Microsoft Administering Relational Databases on Microsoft Azure Sample Questions (Q117-Q122):

NEW QUESTION # 117
You are creating a new notebook in Azure Databricks that will support R as the primary language but will also support Scala and SQL.
Which switch should you use to switch between languages?

Answer: A

Explanation:
Section: [none]
Explanation:
You can override the default language by specifying the language magic command %<language> at the beginning of a cell. The supported magic commands are: %python, %r, %scala, and %sql.
Reference:

NEW QUESTION # 118
You are building an Azure virtual machine.
You allocate two 1-TiB, P30 premium storage disks to the virtual machine. Each disk provides 5,000 IOPS.
You plan to migrate an on-premises instance of Microsoft SQL Server to the virtual machine. The instance has a database that contains a 1.2-TiB data file. The database requires 10,000 IOPS.
You need to configure storage for the virtual machine to support the database.
Which three objects should you create in sequence? To answer, move the appropriate objects from the list of objects to the answer area and arrange them in the correct order.

Answer:

Explanation:

Explanation:

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 # 119
You have an Azure subscription that contains an Azure SQL database named SQL1.
SQL1 is in an Azure region that does not support availability zones.
You need to ensure that you have a secondary replica of SQLI in the same region.
What should you use?

Answer: C

Explanation:
Basic Concept: This question tests high availability and disaster recovery design for Azure SQL, SQL Server on Azure VMs, and regional failure scenarios.
Why C is Correct: Active geo-replication creates readable secondary databases, but failover groups add the managed listener and automatic failover abstraction needed for application continuity at scale. This fits the case because the requested outcome is: You need to ensure that you have a secondary replica of SQLI in the same region. The selected feature addresses that outcome directly rather than relying on a workaround.
Why A is Wrong: Log shipping is a SQL Server HA/DR technique that copies and restores log backups to a secondary database; it is more manual and operationally heavier for Azure SQL Managed Instance migration than LRS. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.
Why B is Wrong: Auto-failover groups provide managed geo-replication and listener-based failover for Azure SQL Database or Managed Instance, including automatic failover policies for regional outages. It handles a different resilience pattern and would not deliver the failover or recovery behavior required here.
Why D is Wrong: Microsoft SQL Server failover clusters is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.


NEW QUESTION # 120
You have a burstable Azure virtual machine named VMI that hosts an instance of Microsoft SQL Server.
You need to attach an Azure ultra disk to VMI. The solution must minimize downtime on VMI.
In which order should you perform the actions? To answer, move all actions from the list of actions to the answer area and arrange them in the correct order.

Answer:

Explanation:

Explanation:

Basic Concept: This question tests plan and configure a high availability and disaster recovery (ha/dr) environment in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You need to attach an Azure ultra disk to VMI.
Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.


NEW QUESTION # 121
You are developing an application that uses Azure Data Lake Storage Gen 2.
You need to recommend a solution to grant permissions to a specific application for a limited time period.
What should you include in the recommendation?

Answer: A

Explanation:
Section: [none]
Explanation:
A shared access signature (SAS) provides secure delegated access to resources in your storage account. With a SAS, you have granular control over how a client can access your data. For example:
What resources the client may access.
What permissions they have to those resources.
How long the SAS is valid.
Note: Data Lake Storage Gen2 supports the following authorization mechanisms:
* Shared Key authorization
* Shared access signature (SAS) authorization
* Role-based access control (Azure RBAC)
Access control lists (ACL) Data Lake Storage Gen2 supports the following authorization mechanisms:
* Shared Key authorization
* Shared access signature (SAS) authorization
* Role-based access control (Azure RBAC)
* Access control lists (ACL)
