When deploying an NSX Edge Transport Node, what two valid IP address assignment options should be specified for the TEP IP addresses? (Choose two.)
- A. Use BootP
- B. Use a Static IP List
- C. Use a DHCP Server
- D. Use RADIUS
- E. Use an IP Pool
Answer: B,E
Explanation:
Explanation
When deploying an NSX Edge Transport Node, two valid IP address assignment options that should be specified for the TEP IP addresses are Use an IP Pool and Use a Static IP List. These options allow the user to assign TEP IP addresses from a predefined range of IP addresses or a manually entered list of IP addresses, respectively345. The other options are incorrect because they are not supported methods for assigning TEP IP addresses. There is no option to use a DHCP server, RADIUS, or BootP for TEP IP address assignment in NSX-T345.

NEW QUESTION # 36
Which three of the following describe the Border Gateway Routing Protocol (BGP) configuration on a Tier-0 Gateway? (Choose three.)
- A. Can be used as an Exterior Gateway Protocol.
- B. FIGRP Is disabled by default.
- C. The network is divided into areas that are logical groups.
- D. BGP is enabled by default.
- E. It supports a 4-byte autonomous system number.
Answer: A,B,E
Explanation:
The answer is A, B, and D.
A) Can be used as an Exterior Gateway Protocol. This is correct. BGP is a protocol that can be used to exchange routing information between different autonomous systems (AS). An AS is a network or a group of networks under a single administrative control. BGP can be used as an Exterior Gateway Protocol (EGP) to connect an AS to other ASes on the internet or other external networks1 B) It supports a 4-byte autonomous system number. This is correct. BGP supports both 2-byte and 4-byte AS numbers. A 2-byte AS number can range from 1 to 65535, while a 4-byte AS number can range from 65536 to 4294967295. NSX supports both 2-byte and 4-byte AS numbers for BGP configuration on a Tier-0 Gateway2 C) The network is divided into areas that are logical groups. This is incorrect. This statement describes OSPF, not BGP. OSPF is another routing protocol that operates within a single AS and divides the network into areas to reduce routing overhead and improve scalability. BGP does not use the concept of areas, but rather uses attributes, policies, and filters to control the routing decisions and traffic flow3 D) FIGRP Is disabled by default. This is correct. FIGRP stands for Fast Interior Gateway Routing Protocol, which is an enhanced version of IGRP, an obsolete routing protocol developed by Cisco. FIGRP is not supported by NSX and is disabled by default on a Tier-0 Gateway.
E) BGP is enabled by default. This is incorrect. BGP is not enabled by default on a Tier-0 Gateway. To enable BGP, you need to configure the local AS number and the BGP neighbors on the Tier-0 Gateway using the NSX Manager UI or API.
To learn more about BGP configuration on a Tier-0 Gateway in NSX, you can refer to the following resources:

NEW QUESTION # 37
What are two valid BGP Attributes that can be used to influence the route path traffic will take? (Choose two.)
- A. BFD
- B. Cost
- C. MED
- D. AS-Path Prepend
Answer: C,D
Explanation:
* AS-Path Prepend: This attribute allows you to prepend one or more AS numbers to the AS path of a route, making it appear longer and less preferable to other BGP routers. You can use this attribute to manipulate the inbound traffic from your BGP peers by advertising a longer AS path for some routes and a shorter AS path for others .
* MED: This attribute stands for Multi-Exit Discriminator and allows you to specify a preference value for a route among multiple exit points from an AS. You can use this attribute to manipulate the outbound traffic to your BGP peers by advertising a lower MED value for some routes and a higher MED value for others .
NEW QUESTION # 38
What needs to be configured on a Tler-0 Gateway lo make NSX Edge Services available to a VM on a VLAN-backed logical switch?
- A. Downlink Interface
- B. Loopback Router Port
- C. Service Interface
- D. VLAN Uplink
Answer: D
Explanation:
Explanation
According to the VMware NSX Documentation, a VLAN uplink is required on a tier-0 gateway to make NSX Edge Services available to a VM on a VLAN-backed logical switch. A VLAN uplink connects a tier-0 gateway to a physical network using VLAN tags. A VLAN uplink can also provide north-south connectivity for overlay segments that are attached to a tier-0 gateway.
NEW QUESTION # 39
A company Is deploying NSX micro-segmentation in their vSphere environment to secure a simple application composed of web. app, and database tiers.
The naming convention will be:
* WKS-WEB-SRV-XXX
* WKY-APP-SRR-XXX
* WKI-DB-SRR-XXX
What is the optimal way to group them to enforce security policies from NSX?
- A. Group all by means of tags membership.
- B. Use Edge as a firewall between tiers.
- C. Create an Ethernet based security policy.
- D. Do a service insertion to accomplish the task.
Answer: A
Explanation:
Explanation
The answer is C. Group all by means of tags membership.
Tags are metadata that can be applied to physical servers, virtual machines, logical ports, and logical segments in NSX. Tags can be used for dynamic security group membership, which allows for granular and flexible enforcement of security policies based on various criteria1 In the scenario, the company is deploying NSX micro-segmentation to secure a simple application composed of web, app, and database tiers. The naming convention will be:
WKS-WEB-SRV-XXX
WKY-APP-SRR-XXX
WKI-DB-SRR-XXX
The optimal way to group them to enforce security policies from NSX is to use tags membership. For example, the company can create three tags: Web, App, and DB, and assign them to the corresponding VMs based on their names. Then, the company can create three security groups: Web-SG, App-SG, and DB-SG, and use the tags as the membership criteria. Finally, the company can create and apply security policies to the security groups based on the desired rules and actions2 Using tags membership has several advantages over the other options:
It is more scalable and dynamic than using Edge as a firewall between tiers. Edge firewall is a centralized solution that can create bottlenecks and performance issues when handling large amounts of traffic3 It is more simple and efficient than doing a service insertion to accomplish the task. Service insertion is a feature that allows for integrating third-party services with NSX, such as antivirus or intrusion prevention systems. Service insertion is not necessary for basic micro-segmentation and can introduce additional complexity and overhead.
It is more flexible and granular than creating an Ethernet based security policy. Ethernet based security policy is a type of policy that uses MAC addresses as the source or destination criteria. Ethernet based security policy is limited by the scope of layer 2 domains and does not support logical constructs such as segments or groups.
To learn more about tags membership and how to use it for micro-segmentation in NSX, you can refer to the following resources:

NEW QUESTION # 40
Which of the two following characteristics about NAT64 are true? (Choose two.)
- A. NAT64 is supported on Tier-1 gateways only.
- B. NAT64 requires the Tier-1 gateway to be configured in active-standby mode.
- C. NAT64 requires the Tier-1 gateway to be configured in active-active mode.
- D. NAT64 is stateless and requires gateways to be deployed in active-standby mode.
- E. NAT64 is supported on Tier-0 and Tier-1 gateways.
Answer: C,E
Explanation:
Explanation
NAT64 is a type of NAT that allows IPv6-only hosts to communicate with IPv4-only hosts by translating the IPv6 addresses to IPv4 addresses and vice versa.
C: NAT64 is supported on Tier-0 and Tier-1 gateways. This is stated in the first result1, which says
"Three types of NAT are supported, in addition to NAT64."
E: NAT64 requires the Tier-1 gateway to be configured in active-active mode. This is implied by the third result2, which says "Stateful NAT is not supported in active-active mode." Since NAT64 is stateless, it can be supported in active-active mode.
NEW QUESTION # 41
A customer has a network where BGP has been enabled and the BGP neighbor is configured on the Tier-0 Gateway. An NSX administrator used the get gateways command to retrieve this Information:
Which two commands must be executed to check BGP neighbor status? (Choose two.)
- A. sa-nexedge-01(tier1_sr> get bgp neighbor
- B. sa-nexedge-01(tier1_dr)> get bgp neighbor
- C. vrf 3
- D. sa-nexedge-01(tier0_sr> get bgp neighbor
- E. vrf 1
- F. vrf 4
Answer: D,F
Explanation:
Explanation
According to the image that you sent, the BGP neighbor is configured on the tier-0 gateway with the UUID
9f8e3a7c-5f9c-4d1a-bb6f-9c7f3d6f3d63 and the VRF ID 4. Therefore, to check the BGP neighbor status, you need to enter the VRF context of 4 and execute the get bgp neighbor command on the tier-0 service router (SR) node.
The other options are either incorrect or not applicable for this scenario. vrf 1, vrf 3, and sa-nexedge-01(tier1_dr)> get bgp neighbor are not related to the BGP neighbor configuration on the tier-0 gateway. sa-nexedge-01(tier1_sr> get bgp neighbor is also not relevant, as there is no BGP neighbor configured on the tier-1 gateway.
NEW QUESTION # 42
When configuring OSPF on a Tler-0 Gateway, which three of the following must match in order to establish a neighbor relationship with an upstream router? (Choose three.)
- A. Area ID
- B. Naming convention
- C. Protocol and Port
- D. Subnet mask
- E. MTU of the Uplink
- F. Address of the neighbor
Answer: A,D,E
Explanation:
Explanation
according to the VMware NSX Documentation, these are the three parameters that must match in order to establish an OSPF neighbor relationship with an upstream router on a tier-0 gateway:
MTU of the Uplink: The maximum transmission unit (MTU) of the uplink interface must match the MTU of the upstream router interface. Otherwise, OSPF packets may be fragmented or dropped, causing neighbor adjacency issues.
Subnet mask: The subnet mask of the uplink interface must match the subnet mask of the upstream router interface. Otherwise, OSPF packets may not reach the correct destination or be rejected by the upstream router.
Area ID: The area ID of the uplink interface must match the area ID of the upstream router interface.
Otherwise, OSPF packets may be ignored or discarded by the upstream router.

NEW QUESTION # 44
An administrator is configuring service insertion for Network Introspection.
Which two places can the Network Introspection be configured? (Choose two.)
- A. Partner SVM
- B. Host pNIC
- C. Tier-0 gateway
- D. Edge Node
- E. Tier-1 gateway
Answer: A,B
Explanation:
Explanation
Network Introspection is a service insertion feature that allows third-party network security services to monitor and analyze the traffic between virtual machines. Network Introspection can be configured on the host pNIC or on the partner SVM, depending on the type of service and the deployment model. The host pNIC configuration is used for services that require traffic redirection from the physical network to the service virtual machine. The partner SVM configuration is used for services that require traffic redirection from the virtual network to the service virtual machine. Network Introspection cannot be configured on the Tier-0 or Tier-1 gateways, as they are not part of the data plane where the service insertion occurs. Network Introspection also cannot be configured on the edge node, as it is a logical construct that hosts the Tier-0 and Tier-1 gateways.

NEW QUESTION # 45
Which two statements are true about IDS Signatures? (Choose two.)
- A. Users can upload their own IDS signature definitions.
- B. An IDS signature contains a set of instructions that determine which traffic is analyzed.
- C. An IDS signature contains data used to identify the creator of known exploits and vulnerabilities.
- D. IDS signatures can be High Risk, Suspicious, Low Risk and Trustworthy.
- E. An IDS signature contains data used to identify known exploits and vulnerabilities.
Answer: B,E
Explanation:
According to the Network Bachelor article1, an IDS signature contains data used to identify an attacker's attempt to exploit a known vulnerability in both the operating system and applications. This implies that statement B is true. According to the VMware NSX Documentation2, IDS/IPS Profiles are used to group signatures, which can then be applied to select applications and traffic. This implies that statement E is true. Statement A is false because users cannot upload their own IDS signature definitions, they have to use the ones provided by VMware or Trustwave3. Statement C is false because an IDS signature does not contain data used to identify the creator of known exploits and vulnerabilities, only the exploits and vulnerabilities themselves. Statement D is false because IDS signatures are classified into one of the following severity categories: Critical, High, Medium, Low, or Informational1.
NEW QUESTION # 46
Which choice is a valid insertion point for North-South network introspection?
- A. Partner SVM
- B. Host Physical NIC
- C. Guest VM vNIC
- D. Tier-0 gateway
Answer: A
Explanation:
According to the VMware NSX Documentation, Partner SVM is a valid insertion point for north-south network introspection. Network introspection is a feature that allows you to insert third-party network services into the data path of your traffic. Partner SVM stands for Partner Service Virtual Machine and is a virtual appliance that runs on an NSX Edge node and provides network services from a partner solution.
NEW QUESTION # 47
An NSX administrator would like to export syslog events that capture messages related to NSX host preparation events. Which message ID (msgld) should be used in the syslog export configuration command as a filler?
- A. MONISTORING
- B. SYSTEM
- C. FABRIC
- D. GROUPING
Answer: C
Explanation:
Explanation
According to the VMware NSX Documentation2, the FABRIC message ID (msgld) captures messages related to NSX host preparation events, such as installation, upgrade, or uninstallation of NSX components on ESXi hosts. The syslog export configuration command for NSX host preparation events would look something like this:
set service syslog export FABRIC
The other options are either incorrect or not relevant for NSX host preparation events. MONITORING captures messages related to NSX monitoring features, such as alarms and system events2. SYSTEM captures messages related to NSX system events, such as login, logout, or configuration changes2. GROUPING captures messages related to NSX grouping objects, such as security groups, security tags, or IP sets2.

NEW QUESTION # 50
Which troubleshooting step will resolve an error with code 1001 during the configuration of a time-based firewall rule?
- A. Changing the lime zone on the ESXi host.
- B. Restarting the NTPservice on the ESXi host.
- C. Reconfiguring the ESXI host with a local NTP server.
- D. Reinstalling the NSX VIBs on the ESXi host.
Answer: B
Explanation:
According to the web search results, error code 1001 is related to a time synchronization issue between the ESXi host and the NSX Manager. This can cause problems when configuring a time-based firewall rule, which requires the ESXi host and the NSX Manager to have the same time zone and NTP server settings . To resolve this error, you need to restart the NTP service on the ESXi host to synchronize the time with the NSX Manager. You can use the following command to restart the NTP service on the ESXi host:
/etc/init.d/ntpd restart
The other options are not valid solutions for this error. Reinstalling the NSX VIBs on the ESXi host will not fix the time synchronization issue. Changing the time zone on the ESXi host may cause more discrepancies with the NSX Manager. Reconfiguring the ESXi host with a local NTP server may not be compatible with the NSX Manager's NTP server.
