NEW QUESTION # 58
What should you implement to meet the disaster recovery requirements for the PaaS solution?

A. Availability Zones
B. geo-replication
C. failover groups
D. Always On availability groups

Answer: C

Explanation:
Section: [none]
Explanation:
Scenario: In the event of an Azure regional outage, ensure that the customers can access the PaaS solution
with minimal downtime. The solution must provide automatic failover.
The auto-failover groups feature allows you to manage the replication and failover of a group of databases on a
server or all databases in a managed instance to another region. It is a declarative abstraction on top of the
existing active geo-replication feature, designed to simplify deployment and management of geo-replicated
databases at scale. You can initiate failover manually or you can delegate it to the Azure service based on a
user-defined policy.
The latter option allows you to automatically recover multiple related databases in a secondary region after a
catastrophic failure or other unplanned event that results in full or partial loss of the SQL Database or SQL
Managed Instance availability in the primary region.

NEW QUESTION # 61
You need to trigger an Azure Data Factory pipeline when a file arrives in an Azure Data Lake Storage Gen2 container.
Which resource provider should you enable?

A. Microsoft.EventGrid
B. Microsoft.EventHub
C. Microsoft.Automation
D. Microsoft.Sql

Answer: A

Explanation:
Event-driven architecture (EDA) is a common data integration pattern that involves production, detection, consumption, and reaction to events. Data integration scenarios often require Data Factory customers to trigger pipelines based on events happening in storage account, such as the arrival or deletion of a file in Azure Blob Storage account. Data Factory natively integrates with Azure Event Grid, which lets you trigger pipelines on such events.

NEW QUESTION # 62
You have an Azure SQL database.
You discover that the plan cache is full of compiled plans that were used only once.
You run the select * from sys.database_scoped_configurationsTransact-SQL command and receive the results shown in the following table.

You need relieve the memory pressure.
What should you configure?

A. ACCELERATED_PLAN_FORCING
B. QUERY_OPTIMIZER_HOTFIXES
C. OPTIMIZE_FOR_AD_HOC_WORKLOADS
D. LEGACY_CARDINALITY_ESTIMATION

Answer: C

Explanation:
Section: [none]
Explanation:
OPTIMIZE_FOR_AD_HOC_WORKLOADS = { ON | OFF }
Enables or disables a compiled plan stub to be stored in cache when a batch is compiled for the first time. The default is OFF. Once the database scoped configuration OPTIMIZE_FOR_AD_HOC_WORKLOADS is enabled for a database, a compiled plan stub will be stored in cache when a batch is compiled for the first time. Plan stubs have a smaller memory footprint compared to the size of the full compiled plan.
Incorrect Answers:
A: LEGACY_CARDINALITY_ESTIMATION = { ON | OFF | PRIMARY }
Enables you to set the query optimizer cardinality estimation model to the SQL Server 2012 and earlier version independent of the compatibility level of the database. The default is OFF, which sets the query optimizer cardinality estimation model based on the compatibility level of the database.
B: QUERY_OPTIMIZER_HOTFIXES = { ON | OFF | PRIMARY }
Enables or disables query optimization hotfixes regardless of the compatibility level of the database. The default is OFF, which disables query optimization hotfixes that were released after the highest available compatibility level was introduced for a specific version (post-RTM).

Follow these same steps to create striped virtual disk:
* Create Log Storage Pool.
* Create Virtual Disk
* Create Volume
Box 1: a storage pool
Box 2: a virtual disk that uses stripe layout
Disk Striping: Use multiple disks and stripe them together to get a combined higher IOPS and Throughput limit.
The combined limit per VM should be higher than the combined limits of attached premium disks.
Box 3: a volume

NEW QUESTION # 65
You have a new Azure SQL database. The database contains a column that stores confidential information.
You need to track each time values from the column are returned in a query. The tracking information must be stored for 365 days from the date the query was executed.
Which three actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

A. Turn on auditing and write audit logs to an Azure Storage account.
B. Turn on Azure Advanced Threat Protection (ATP).
C. Turn on Advanced Data Security for the Azure SQL server.
D. Apply sensitivity labels named Highly Confidential to the column.
E. Add extended properties to the column.

Answer: A,C,D

Explanation:
C: Advanced Data Security (ADS) is a unified package for advanced SQL security capabilities. ADS is available for Azure SQL Database, Azure SQL Managed Instance, and Azure Synapse Analytics. It includes functionality for discovering and classifying sensitive data D: You can apply sensitivity-classification labels persistently to columns by using new metadata attributes that have been added to the SQL Server database engine. This metadata can then be used for advanced, sensitivity-based auditing and protection scenarios.
A: An important aspect of the information-protection paradigm is the ability to monitor access to sensitive data. Azure SQL Auditing has been enhanced to include a new field in the audit log called data_sensitivity_information. This field logs the sensitivity classifications (labels) of the data that was returned by a query. Here's an example:

Answer:

Explanation:

NEW QUESTION # 67
You have an Azure SQL database named DB1.
You need to ensure that DB1 will support automatic failover without data loss if a datacenter fails. The solution must minimize costs.
Which deployment option and pricing tier should you configure?

A. Azure SQL Database Hyperscale
B. Azure SQL Database Basic
C. This feature is not available in SQL Managed Instance.
D. Azure SQL Database managed instance General Purpose
E. Azure SQL Database Premium

Answer: E

Explanation:
By default, the cluster of nodes for the premium availability model is created in the same datacenter. With the introduction of Azure Availability Zones, SQL Database can place different replicas of the Business Critical database to different availability zones in the same region. To eliminate a single point of failure, the control ring is also duplicated across multiple zones as three gateway rings (GW). The routing to a specific gateway ring is controlled by Azure Traffic Manager (ATM). Because the zone redundant configuration in the Premium or Business Critical service tiers does not create additional database redundancy, you can enable it at no extra cost. By selecting a zone redundant configuration, you can make your Premium or Business Critical databases resilient to a much larger set of failures, including catastrophic datacenter outages, without any changes to the application logic. You can also convert any existing Premium or Business Critical databases or pools to the zone redundant configuration.

NEW QUESTION # 68
You have an Azure SQL database that contains a table named Employees. Employees contains a column named Salary.
You need to encrypt the Salary column. The solution must prevent database administrators from reading the data in the Salary column and must provide the most secure encryption.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Answer:

Explanation:

Explanation:
Step 1: Create a column master key
Create a column master key metadata entry before you create a column encryption key metadata entry in the database and before any column in the database can be encrypted using Always Encrypted.
Step 2: Create a column encryption key.
Step 3: Encrypt the Salary column by using the randomized encryption type.
Randomized encryption uses a method that encrypts data in a less predictable manner. Randomized encryption is more secure, but prevents searching, grouping, indexing, and joining on encrypted columns.
Note: A column encryption key metadata object contains one or two encrypted values of a column encryption key that is used to encrypt data in a column. Each value is encrypted using a column master key.
Incorrect Answers:
Deterministic encryption.
Deterministic encryption always generates the same encrypted value for any given plain text value. Using deterministic encryption allows point lookups, equality joins, grouping and indexing on encrypted columns. However, it may also allow unauthorized users to guess information about encrypted values by examining patterns in the encrypted column, especially if there's a small set of possible encrypted values, such as True/False, or North/South/East/West region.
