NEW QUESTION # 17
You use Juniper Apstra to enable a new VXLAN virtual network.
Which two components would be automatically derived in this situation? (Choose two.)
- A. Route Zone
- B. IP subnet
- C. VXLAN VNI
- D. VLAN-ID
Answer: B,C
Explanation:
According to the Juniper documentation1, a VXLAN virtual network is a collection of Layer 2 forwarding domains that span multiple racks in a fabric. A VXLAN virtual network requires a name and a VXLAN network identifier (VNI), which is a 24-bit number that identifies the virtual network. The VNI can be either explicitly assigned or auto-assigned from a resource pool. A VXLAN virtual network can also have Layer 3 connectivity, which enables routing between different VNIs within a routing zone. A routing zone is an L3 domain that isolates the IP traffic of different tenants. A routing zone can have one or more VNIs associated with it. To enable Layer 3 connectivity, a VXLAN virtual network needs an IP subnet, which is a range of IP addresses that can be assigned to the hosts in the virtual network. The IP subnet can be either explicitly assigned or auto-assigned from a resource pool. Therefore, the correct answer is A and C. IP subnet and VXLAN VNI are two components that would be automatically derived when enabling a new VXLAN virtual network using Juniper Apstra.

NEW QUESTION # 18
Which statement about Juniper Apstra role-based access control is correct?
- A. The user role can create roles.
- B. The viewer role is predefined and can be deleted.
- C. The administrator role can see all permissions.
- D. The administrator role is the only predefined role.
Answer: C
Explanation:
Juniper Apstra role-based access control (RBAC) is a feature that allows you to specify access permissions for different users based on their roles. RBAC servers are remote network servers that authenticate and authorize network access based on roles assigned to individual users within an enterprise1. Juniper Apstra has four predefined user roles: administrator, device_ztp, user, and viewer2. The administrator role is the most powerful role, and it can see all permissions and perform all actions in the Apstra software application. The administrator role can also create, clone, edit, and delete user roles, except for the four predefined user roles, which cannot be modified2. Therefore, the statement that the administrator role can see all permissions is correct.
The following three statements are incorrect in this scenario:
* The viewer role is predefined and can be deleted. This is not true, because the viewer role is one of the four predefined user roles, and it cannot be deleted. The viewer role is the most restricted role, and it can only view the network information and configuration, but not make any changes2.
* The user role can create roles. This is not true, because the user role is one of the four predefined user roles, and it cannot create roles. The user role can perform most of the network configuration and management tasks, but it cannot access the platform settings or the user management features2.
* The administrator role is the only predefined role. This is not true, because there are four predefined user roles, not just one. The other three predefined user roles are device_ztp, user, and viewer2.

NEW QUESTION # 19
You must configure a static route for traffic to exit a configured routing zone. In the Juniper Apstra Ul. where would you accomplish this task?
- A. under Active -> Virtual -> Routing Zones
- B. under Staged -> Virtual -> Routing Zones
- C. under Staged -> Connectivity Templates
- D. under Active -> Connectivity Templates
Answer: C
Explanation:
To configure a static route for traffic to exit a configured routing zone, you need to use the Connectivity Templates feature in the Juniper Apstra UI. A Connectivity Template is a set of configuration parameters that can be applied to a device or a group of devices in a blueprint. You can use Connectivity Templates to configure static routes, BGP, OSPF, and other network services. To create a Connectivity Template, you need to go to the Staged tab and select Connectivity Templates from the left menu. Then, you can click on the + icon to create a new template. You can specify the name, description, andscope of the template. The scope determines which devices or device groups the template will be applied to. You can also specify the order of the template, which determines the priority of the template when multiple templates are applied to the same device. After creating the template, you can add configuration items to the template. To add a static route, you need to select Static Route from the drop-down menu and enter the destination network, subnet mask, and next-hop IP address. You can also specify the administrative distance and the track object for the static route.
After adding the configuration items, you need to save the template and commit the changes to the blueprint.
The other options are incorrect because:
* A. under Active -> Virtual -> Routing Zones is wrong because this option allows you to view and modify the existing routing zones, but not to configure static routes for them.
* B. under Staged -> Virtual -> Routing Zones is wrong because this option allows you to create and delete routing zones, but not to configure static routes for them.
* C. under Active -> Connectivity Templates is wrong because this option allows you to view the existing connectivity templates, but not to create or modify them. References:

NEW QUESTION # 20
What does EVPN use lo identity which remote leaf device advertised the EVPN route?
- A. a community tag
- B. a VRF target value
- C. a route distinguisher value
- D. a route target value
Answer: C
Explanation:
EVPN uses a route distinguisher (RD) value to identify which remote leaf device advertised the EVPN route.
An RD is a 64-bit value that is prepended to the EVPN NLRI to create a unique VPNv4 or VPNv6 prefix. The RD value is usually derived from the IP address of the PE that originates the EVPN route. By comparing the RD values of different EVPN routes, a PE can determine which remote PE advertised the route and which VRF the route belongs to. The other options are incorrect because:
* B. a community tag is wrong because a community tag is an optional transitive BGP attribute that can be used to group destinations that share some common properties. A community tag does not identify the source of the EVPN route.
* C. a route target value is wrong because a route target (RT) value is an extended BGP community that is used to control the import and export of EVPN routes between VRFs. An RT value does not identify the source of the EVPN route.
* D. a VRF target value is wrong because there is no such thing as a VRF target value in EVPN. A VRF is a virtual routing and forwarding instance that isolates the IP traffic of different VPNs on a PE. A VRF does not have a target value associated with it. References:

NEW QUESTION # 21
You are adding a new switch to Juniper Apstra software. The Managed Devices page shows the "0 OS-Quarantined" status. What is the proper next step to make the device ready for use in a blueprint?
- A. Acknowledge the device.
- B. Take the device out of maintenance mode.
- C. Take the device out of drain state.
- D. Install the agent for the device.
Answer: A
Explanation:
When a new switch is added to Juniper Apstra software, it initially shows the "0 OS-Quarantined" status, which means that the device is not yet managed by Apstra and has not been assigned to any blueprint. The proper next step to make the device ready for use in a blueprint is to acknowledge the device, which is a manual action that confirms the device identity and ownership. Acknowledging the device changes its status to
"OOS-Ready", which means that the device is ready to be assigned to a blueprint and deployed12. References

NEW QUESTION # 22
Exhibit.
Referring to the exhibit, how many tack types ate used in the staged blueprint?
- A. three
- B. six
- C. seven
- D. two
Answer: D
Explanation:
Referring to the exhibit, the image shows the Racks table under the Staged menu in the Juniper Apstra UI. The Racks table displays the details of the racks that are used in the blueprint, such as the name, rack type, and date. The rack type is a resource that defines the type and number of leaf devices, access switches, and/or generic systems that are used in rack builds1. The image shows seven racks in the table, but only two rack types: BorderLeaf and ServerRack. Therefore, the statement D is correct in this scenario.
The following three statements are incorrect in this scenario:
* A. six. This is not true, because there are not six rack types in the table, but only two. The number six corresponds to the number of racks that have the same rack type: ServerRack.
* B. three. This is not true, because there are not three rack types in the table, but only two. The number
* three does not correspond to any relevant information in the table or the image.
* C. seven. This is not true, because there are not seven rack types in the table, but only two. The number seven corresponds to the total number of racks in the table, not the rack types.

NEW QUESTION # 23
You want to apply a configlet to a specific device using Juniper Apstra. Which two parameters would be used to accomplish this task? (Choose two.)
- A. hostname
- B. tags
- C. port group
- D. form factor
Answer: A,B
Explanation:
To apply a configlet to a specific device using Juniper Apstra, you need to specify the device's hostname and tags. The hostname is the unique identifier of the device in the Apstra system, and the tags are the labels that you can assign to the device to group it with other devices that share the same characteristics. You can use the hostname and tags to filter the devices that you want to apply the configlet to in the blueprint catalog12.

NEW QUESTION # 24
Using Juniper Apstra. which component is defined in a template?
- A. the definition of IP pools
- B. the leaf-to-spine interconnection
- C. the number of spine devices in a topology
- D. the speed of the links between the spine devices and the leaf devices
Answer: B
Explanation:
According to the Juniper documentation1, a template is a configuration template that defines a network's policy intent and structure. A template can be either rack-based or pod-based, depending on the type and number of racks and pods in the network design. A template includes the following details:
* Policies: These are the parameters that apply to the entire network, such as the overlay control protocol, the ASN allocation scheme, and the underlay type.
* Structure: This is the physical layout of the network, such as the type and number of racks, pods, spines, and leaves. The structure also defines the leaf-to-spine interconnection, which is the number and type of links between the leaf and spine devices. The leaf-to-spine interconnection can be either single or dual, depending on the redundancy and bandwidth requirements.
Therefore, the correct answer is A. the leaf-to-spine interconnection. This is a component that is defined in a template, as it determines the physical connectivity of the network. The speed of the links, the number of spine devices, and the definition of IP pools are not components that are defined in a template, as they are either derived from the device profiles, the resource pools, or the blueprint settings.

NEW QUESTION # 25
IBA probes analyze telemetry data from specified devices within a blueprint. Which component Identities devices that supply data tor a specific probe?
- A. graph query
- B. processor
- C. search engine
- D. data selector
Answer: A
Explanation:
A graph query is a component that identifies devices that supply data for a specific probe. A graph query is an expression that matches nodes in the Apstra graph database based on their attributes, such as device name, role, type, or tag. A graph query can be used to select the source devices for the input processors of a probe, as well as to filter the data by device attributes in the subsequent processors of a probe12. References:

NEW QUESTION # 26
When an agent installation is successful, devices are placed into which state using the Juniper Apstra Ul?
- A. OOS-READY
- B. OOS-QUARANTINED
- C. IS-ACTIVE
- D. IS-MAINT
Answer: B
Explanation:
When an agent installation is successful, devices are placed into the Out of Service Quarantined (OOS-QUARANTINED) state using the Juniper Apstra UI. This state means that the device is not yet managed by Apstra and has not been assigned to any blueprint. The device configuration at this point is called Pristine Config. To make the device ready for use in a blueprint, you need toacknowledge the device, which changes its state to Out of Service Ready (OOS-READY)12. References:

NEW QUESTION # 27
A member of your organization made changes to a predefined interface map using Juniper Apstra.
Which two statements are correct in this scenario? (Choose two.)
- A. Changes made to predefined interface maps will not have an impact on the Apstra software.
- B. Any changes made to predefined interface maps are discarded when Apstra is upgraded.
- C. Changes to interface maps in the global catalog do not affect interface maps that have already been imported into blueprint catalogs
- D. Changes to interface maps in the global catalog will raise anomalies that may need to be addressed at the next commit.
Answer: B,C
Explanation:
According to the Juniper documentation1, an interface map is a configuration template that maps interfaces between logical devices and physical hardware devices (represented with device profiles) while adhering to vendor specifications. An interface map can be either predefined or custom. A predefined interface map is one that ships with Apstra software and supports most qualified Juniper devices. A custom interface map is one that is created by the user to meet specific requirements. An interface map can be stored in either the global catalog or the blueprint catalog. The global catalog contains all the interface maps that are available for use in any blueprint. The blueprint catalog contains the interface maps that are imported from the global catalog and used in a specific blueprint.
When a member of your organization makes changes to a predefined interface map, the following statements are correct:
* Changes to interface maps in the global catalog do not affect interface maps that have already been imported into blueprint catalogs. This means that the existing blueprints that use the original version of the interface map will not be impacted by the changes. However, if you want to use the updated version of the interface map in a new or existing blueprint, you need to import it again from the global catalog.
* Any changes made to predefined interface maps are discarded when Apstra is upgraded. This means that the changes will not be preserved across different versions of Apstra software. If you want to retain a customized interface map through Apstra upgrades, you need to clone the predefined interface map, give it a unique name, and customize it instead of changing the predefined one directly.
Therefore, the correct answer is A and B. Changes to interface maps in the global catalog do not affect interface maps that have already been imported into blueprint catalogs and any changes made to predefined interface maps are discarded when Apstra is upgraded.

NEW QUESTION # 28
In Juniper Apstra. which statement is correct?
- A. VMware anomaly detection requires an Apstra server running on VMware.
- B. VMware anomaly detection is on by default.
- C. VMware anomaly detection requires a VMware hypervisor with exports enabled.
- D. VMware anomaly detection requires a vCenter server configured under External Systems
Answer: D
Explanation:
VMware anomaly detection is a feature of Apstra that provides visibility and validation of the virtual network settings and the physical network settings in a VMware vSphere environment. To enable this feature, Apstra requires a connection to a vCenter server that manages the ESX/ESXi hosts and the VMs connected to the Apstra-managed leaf switches. The vCenter server must be configured under External Systems in the Apstra web interface, and the vCenter integration must be staged and committed in the blueprint. This allows Apstra to collect information about VMs, ESX/ESXi hosts, port groups, and VDS, and to flag any inconsistencies or mismatches that might affect VM connectivity. The other options are incorrect because:
* VMware anomaly detection is not on by default. It must be enabled by configuring a vCenter server under External Systems and adding a virtual infra to the blueprint.
* VMware anomaly detection does not require a VMware hypervisor with exports enabled. It only requires LLDP transmit to be enabled on the VMware distributed virtual switch to associate host interfaces with leaf interfaces.
* VMware anomaly detection does not require an Apstra server running on VMware. It can run on any supported platform, such as Linux, Windows, or Docker. References:

NEW QUESTION # 29
What are two system-defined user roles that are available in Juniper Apstra? (Choose two.)
- A. user
- B. viewer
- C. root
- D. authorized
Answer: A,B
Explanation:
Juniper Apstra provides four system-defined user roles that are available in the Apstra GUI environment. They are: administrator, device_ztp, viewer, and user1. Based on the web search results, we can infer the following statements:
* viewer: This role includes permissions to only view various elements in the Apstra system, such as blueprints, devices, design, resources, external systems, platform, and others. Users with this role cannot create, edit, or delete any element12.
* user: This role includes permissions to view and edit various elements in the Apstra system, such as blueprints, devices, design, resources, external systems, platform, and others. Users with this role cannot create or delete any element12.
* authorized: This is not a system-defined user role in Juniper Apstra. It is a term used to describe users who have been authenticated by an external system, such as LDAP, Active Directory, TACACS+, or RADIUS3.
* root: This is not a system-defined user role in Juniper Apstra. It is a term used to describe the superuser account on a Linux system, which has full access to all commands and files. Creating a user in the Apstra GUI does not provide that user access to the Apstra platform via SSH. To access the Apstra platform via SSH, you must create a local Linux system user4. References:

NEW QUESTION # 30
Which two statements are correct about probes? (Choose two.)
- A. Default probes are enabled, based on the intent for a blueprint.
- B. All default probes are enabled for all blueprints.
- C. Default probes can be cloned, modified, and saved.
- D. Only the variable parameters tor default probes can be edited and saved.
Answer: A,C
Explanation:
Probes are the basic unit of abstraction in Intent-Based Analytics (IBA). They are used to collect, process, and analyze data from the network and raise anomalies based on specified conditions. Probes are composed of processors and stages that form a directed acyclic graph (DAG) of data flow. The following statements are correct about probes:
* A. Default probes can be cloned, modified, and saved. This is true because Apstra provides a set of default probes that cover common use cases and scenarios. These probes can be cloned and modified to suit the specific needs of the user. The modified probes can be saved as new probes with different names and descriptions. This allows the user to customize and extend the functionality of the default probes.
* D. Default probes are enabled, based on the intent for a blueprint. This is true because Apstra enables or disables the default probes automatically based on the intent of the blueprint. The intent of the blueprint is the high-level description of the desired state and behavior of the network. Apstra uses the intent to determine which default probes are relevant and applicable for the blueprint and enables them accordingly. For example, if the intent of the blueprint is to deployan EVPN-VXLAN fabric, Apstra will enable the default probes related to EVPN-VXLAN, such as EVPN-VXLAN Anomaly Detection, EVPN-VXLAN Fabric Health, and EVPN-VXLAN Fabric Validation. The following statements are incorrect about probes:
* B. Only the variable parameters for default probes can be edited and saved. This is false because the user can edit and save any parameters for the default probes, not just the variable ones. The variable parameters are the ones that depend on the network topology, devices, or configuration, such as device
* names, interface names, IP addresses, VLAN IDs, etc. The user can also edit and save the fixed parameters, such as the duration, threshold, condition, etc. However, the user cannot edit and save the default probes directly. The user must clone the default probes first and then edit and save the cloned probes as new probes.
* C. All default probes are enabled for all blueprints. This is false because Apstra does not enable all default probes for all blueprints. Apstra enables the default probes based on the intent of the blueprint, as explained above. This means that only the default probes that are relevant and applicable for the blueprint are enabled. For example, if the intent of the blueprint is to deploy a BGP IP fabric, Apstra will not enable the default probes related to EVPN-VXLAN, since they are not relevant for the blueprint. The user can also manually enable or disable the default probes as needed. References:

NEW QUESTION # 31
In the Juniper Apstra Ul. which two resource types would be created in the Resources menu? (Choose two.)
- A. ASN pools
- B. DHCP pools
- C. IP pools
- D. bridge domain identifier (BDI)
Answer: A,C
Explanation:
According to the Juniper documentation1, the Resources menu in the Juniper Apstra UI allows you to create and manage various types of resources that are assigned to different elements of the network. Resources include the following types:
* IPv4 (including Host IPv4)
* IPv6 (including Host IPv6)
* ASN (autonomous system number)
* VNI (virtual network identifier)
* VLAN (virtual local area network)
* Integer (used for pool type VLAN in local pools in Freeform blueprints) Therefore, the correct answer is C and D. ASN pools and IP pools are two types of resources that can be created in the Resources menu. Bridge domain identifier (BDI) and DHCP pools are not applicable in this scenario, because they are not part of the resources types supported by Juniper Apstra.

Exhibit.
Which two statements ate correct about the graph query output shown in the exhibit? (Choose two.)
- A. The switch in the output is a Juniper device.
- B. The output shows a LAG connection.
- C. The interface has tags assigned to it.
- D. The interface has an IP address assigned to it.
Answer: A,B
Explanation:
The graph query output shown in the exhibit is a JSON representation of an interface node and its properties in the Apstra graph database. Based on the output, we can infer the following statements:
* The output shows a LAG connection. This is true because the interface node has a property called lag_mode which is set to lacp_active, indicating that the interface is part of a link aggregation group (LAG) that uses the Link Aggregation Control Protocol (LACP) to negotiate the link state and parameters12.
* The switch in the output is a Juniper device. This is true because the interface node has a property called if_name which is set to ae2, indicating that the interface name follows the Juniper naming convention for aggregated Ethernet interfaces34.
* The interface has an IP address assigned to it. This is false because the interface node has properties called ipv4_addr and ipv6_addr which are both set to null, indicating that the interface does not have any IPv4 or IPv6 address configured2.
* The interface has tags assigned to it. This is false because the interface node has a property called tags which is set to null, indicating that the interface does not have any tags associated with it2.

Which protocol is used to advertise EVPN routes?
- A. IS-IS
- B. RIP
- C. OSPF
- D. BGP
Answer: D
Explanation:
BGP is the protocol used to advertise EVPN routes. EVPN routes are a new type of BGP network layer reachability information (NLRI) that carry MAC address and IP prefix information for Ethernet VPNs. EVPN routes are exchanged between PEs using BGP multiprotocol extensions (MP-BGP) over MPLS, VXLAN, SR, or SRv6 tunnels. EVPN routes enable PEs to learn the reachability of MAC addresses and IP prefixes of different sites within the same EVPN instance. EVPN routes also support various features such as fast convergence, redundancy, aliasing, and inter-subnet routing. The other options are incorrect because:
* A. OSPF is wrong because OSPF is an interior gateway protocol (IGP) that is used to advertise IP routes within an autonomous system. OSPF is not used to advertise EVPN routes, which are a type of BGP NLRI that carry MAC address and IP prefix information for Ethernet VPNs.
* C. IS-IS is wrong because IS-IS is an interior gateway protocol (IGP) that is used to advertise IP routes and MPLS labels within an autonomous system. IS-IS is not used to advertise EVPN routes, which are a type of BGP NLRI that carry MAC address and IP prefix information for Ethernet VPNs.
* D. RIP is wrong because RIP is an interior gateway protocol (IGP) that is used to advertise IP routes within an autonomous system. RIP is not used to advertise EVPN routes, which are a type of BGP NLRI that carry MAC address and IP prefix information for Ethernet VPNs. References:

Which statement is correct about the Juniper Apstra Rendered configuration?
- A. It is built at commit time and stored in a MySQL database.
- B. It is dynamically tendered at commit time.
- C. It is rendered from the graph database and stored locally.
- D. It is stored in a NoSQL database and incrementally updated.
Answer: B
Explanation:
The Juniper Apstra Rendered configuration is the configuration that is generated from the staged blueprint and applied to the devices in the network. The Rendered configuration is dynamically rendered at commit time, which means that it is created on the fly based on the latest changes and validations in the blueprint. The Rendered configuration is not stored in any database, but it can be viewed in the Apstra UI or downloaded as a file. The Rendered configuration reflects the desired state of the network as defined by the intent of the blueprint. The other options are incorrect because:
* A. It is built at commit time and stored in a MySQL database is wrong because the Rendered configuration is not stored in any database, let alone a MySQLdatabase. Apstra uses a graph database to store the network topology and configuration data, not a relational database like MySQL.
* B. It is stored in a NoSQL database and incrementally updated is wrong because the Rendered configuration is not stored in any database, let alone a NoSQL database. Apstra uses a graph database to store the network topology and configuration data, not a non-relational database like NoSQL. The Rendered configuration is not incrementally updated, but dynamically rendered at commit time.
* D. It is rendered from the graph database and stored locally is wrong because the Rendered configuration is not rendered from the graph database, but from the staged blueprint. The graph database stores the network topology and configuration data, but the Rendered configuration is generated from the blueprint, which is a logical representation of the network design and intent. The Rendered configuration is not stored locally, but it can be downloaded as a file if needed. References:

NEW QUESTION # 35
In the Juniper Apstra Ul. you are creating a VNI pool for virtual networks.
In this scenario, which VNI range is acceptable?
- A. Any range is acceptable for the VNI pool.
- B. The valid VNI range is 2 through 4096.
- C. The valid VNI range is 4096 through 16777214.
- D. The valid VNI range is 1 through 10000.
Answer: C
Explanation:
In the Juniper Apstra UI, you can create VNI pools for virtual networks that use VXLAN encapsulation in the overlay network. A VNI pool is a resource pool that contains a range of VNIs that can be assigned to the virtual networks. The valid VNI range for a VNI pool is 4096 through 16777214, according to the VXLAN standard1. Therefore, the statement B is correct in this scenario.
The following three statements are incorrect in this scenario:
* Any range is acceptable for the VNI pool. This is not true, because the VNI range has a lower and upper limit defined by the VXLAN standard1. The lower limit is 4096, and the upper limit is 16777214. Any VNI outside this range is invalid and cannot be used for VXLAN encapsulation.
* The valid VNI range is 2 through 4096. This is not true, because the VNI range does not start from 2, but from 4096. The VNIs from 2 to 4095 are reserved and cannot be used for VXLAN encapsulation1.
* The valid VNI range is 1 through 10000. This is not true, because the VNI range does not include 1, which is also reserved and cannot be used for VXLAN encapsulation1. The VNI range also does not end at 10000, but at 16777214, which is the maximum possible value for a 24-bit VNI field1.

NEW QUESTION # 36
Exhibit.
Referring to the exhibit, what needs to change in the IP fabric to make it a valid IP fabric?
- A. The IP fabric must consist of only one device model throughout the fabric.
- B. The connection between the two spine nodes must be removed.
- C. The connection between the two spine nodes must be increased to 40 Gbps.
- D. The IP fabric connections must be increased to a speed greater than 10 Gbps.
Answer: B
Explanation:
To make the IP fabric a valid IP fabric, the connection between the two spine nodes must be removed. This is because an IP fabric is a network topology that uses a spine-leaf architecture, where the spine devices are only connected to the leaf devices, and the leaf devices are only connected to the spine devices. This creates a non-blocking, high-performance, and scalable network that supports Layer 3 routing protocols such as BGP or OSPF. The connection between the two spine nodes in the exhibit violates the spine-leaf design principle and introduces unnecessary complexity and potential loops in the network. The other options are incorrect because:
* A. The IP fabric must consist of only one device model throughout the fabric is wrong because an IP fabric can support different device models as long as they are compatible and interoperable. The exhibit shows two different models of QFX switches, which are both supported by Juniper Networks for IP fabric deployments.
* B. The connection between the two spine nodes must be increased to 40 Gbps is wrong because increasing the speed of the connection does not make the IP fabric valid. The connection between the two spine nodes should be removed, as explained above.
* C. The IP fabric connections must be increased to a speed greater than 10 Gbps is wrong because the speed of the connections does not affect the validity of theIP fabric. The IP fabric can use any speed that meets the bandwidth and performance requirements of the network. 10 Gbps is a common speed for IP fabric connections, but higher or lower speeds can also be used depending on the network design and devices.

- D. Use interconnection through an external gateway.
Answer: D
Explanation:
According to the Juniper documentation1, a routing zone is an L3 domain, the unit of tenancy in multi-tenant networks. You create routing zones for tenants to isolate their IP traffic from one another, thus enabling tenants to re-use IP subnets. In addition to being in its own VRF, each routing zone can be assigned its own DHCP relay server and external system connections. You can create one or more virtual networks within a routing zone, which means a tenant can stretch its L2 applications across multiple racks within its routing zone. For virtual networks with Layer 3 SVI, the SVI is associated with a Virtual Routing and Forwarding (VRF) instance for each routing zone isolating the virtual network SVI from other virtual network SVIs in other routing zones. If you're using multiple routing zones, external system connections must be from leaf switches in the fabric. Routing between routing zones must be accomplished with external systems. Therefore, the correct answer is D. Use interconnection through an external gateway. References: Routing Zones
NEW QUESTION # 38
Which two statements are correct about Time Voyager? {Choose two.)
- A. Time Voyager retains up to twenty-five saved revisions.
- B. Time Voyager retains the last ten blueprint commits.
- C. Time Voyager retains the five most recent blueprint commits.
- D. Time Voyager retains all of the blueprint revisions from the last Juniper Apstra backup.
Answer: A,C
Explanation:
Time Voyager is a feature of Juniper Apstra that allows you to restore previous revisions of a blueprint, which is a logical representation of your network design and configuration. Time Voyager automatically saves the five most recent blueprint commits, which are the changes that you apply to the network. You can also manually save up to twenty-five revisions by keeping them, which prevents them from being overwritten by new commits. Therefore, the correct answer is B and D. Time Voyager retains the five most recent blueprint commits and Time Voyager retains up to twenty-five saved revisions.

NEW QUESTION # 39
Which attribute enables Juniper Apstra to scale and manage thousands of devices with a single server instance?
- A. Apstra is based on NGINX.
- B. Apstra is available as an OVA.
- C. Apstra is a distributed state system.
- D. Apstra is installed as a cloud resource.
Answer: C
Explanation:
The attribute that enables Juniper Apstra to scale and manage thousands of devices with a single server instance is that Apstra is a distributed state system. This means that Apstra uses a graph database to store the network topology and configuration data in a distributed and replicated manner across multiple server nodes.
This allows Apstra to handle large-scale networks with high performance, reliability, and availability. Apstra also uses a stateful orchestration engine that ensures the network state is always consistent with the intent of the blueprint, which is the logical representation of thenetwork design and behavior. Apstra can automatically detect and resolve any discrepancies between the desired and actual network state, as well as handle any changes or failures in the network. The other options are incorrect because:
* A. Apstra is installed as a cloud resource is wrong because Apstra can be installed either as a cloud resource or as an on-premises resource. Apstra is available as a virtual machine image that can be deployed on various hypervisors, such as VMware ESXi, QEMU/KVM, Microsoft Hyper-V, or Oracle VirtualBox. Apstra can also be deployed on public cloud platforms, such as Amazon Web Services (AWS) or Microsoft Azure. However, the installation method does not affect the scalability of Apstra, which is determined by the distributed state system architecture.
* B. Apstra is based on NGINX is wrong because Apstra is not based on NGINX, but on Python and Django. NGINX is a web server and reverse proxy that Apstra uses to serve the web user interface and the REST API. However, NGINX is not the core component of Apstra, and it does not affect the scalability of Apstra, which is determined by the distributed state system architecture.
* C. Apstra is available as an OVA is wrong because Apstra is available as an OVF, not an OVA. An
* OVF (Open Virtualization Format) is a standard format for packaging and distributing virtual machine images. An OVA (Open Virtual Appliance) is a single file that contains the OVF and the virtual disk images. Apstra provides an OVF file that can be imported into various hypervisors, such as VMware ESXi, QEMU/KVM, Microsoft Hyper-V, or Oracle VirtualBox. However, the availability of Apstra as an OVF does not affect the scalability of Apstra, which is determined by the distributed state system architecture. References:

NEW QUESTION # 40
You want to make a widget appear on the main dashboard in Juniper Apstra. In this scenario, which statement is correct?
- A. Widgets automatically appear on the blueprint dashboard.
- B. When creating the widget, select the Add to Blueprint Dashboard option.
- C. On the blueprint dashboard, click on the Add Widget option.
- D. Set the Default toggle switch to On for the desired widget.
Answer: D
Explanation:
In Juniper Apstra, a widget is a graphical element that displays data from an intent-based analytics (IBA) probe. A widget can be used to monitor different aspects of the network and raise alerts to any anomalies. A widget can be viewed by itself or added to an analytics dashboard. A dashboard is a collection of widgets that can be customized and organized according to the user's preference1.
The main dashboard in Juniper Apstra is the blueprint dashboard, which is the default view that shows the network information and configuration for the active blueprint. A blueprint is a logical representation of the network design and intent. The blueprint dashboard can display the system-generated dashboards, the user-generated dashboards, and the individual widgets that are relevant to the network2.
To make a widget appear on the main dashboard in Juniper Apstra, the user needs to set the Default toggle switch to On for the desired widget. This will add the widget to the blueprint dashboard, where it can be viewed along with other network information. The user can also remove the widget from the blueprint dashboard by setting the Default toggle switch to Off for the widget3. Therefore, the statement D is correct in this scenario.
The following three statements are incorrect in this scenario:
* When creating the widget, select the Add to Blueprint Dashboard option. This is not true, because there is no such option when creating a widget in Juniper Apstra. The user can only select the widget type, the probe, and the display mode when creating a widget4. To add the widget to the blueprint dashboard, the user needs to set the Default toggle switch to On for the widget after creating it3.
* On the blueprint dashboard, click on the Add Widget option. This is not true, because there is no such option on the blueprint dashboard in Juniper Apstra. The user can only view, edit, or delete the existing widgets and dashboards on the blueprint dashboard2. To add a widget to the blueprint dashboard, the user needs to set the Default toggle switch to On for the widget from the widgets table view3.
* Widgets automatically appear on the blueprint dashboard. This is not true, because widgets do not automatically appear on the blueprint dashboard in Juniper Apstra. The user needs to manually add the widgets to the blueprint dashboard by setting the Default toggle switch to On for the widgets that they
* want to see on the blueprint dashboard3. The only exception is the widgets that are part of the system-generated dashboards, which are automatically created and added to the blueprint dashboard based on the state of the active blueprint2.
