Question 6 of 94

HOTSPOT -

You use Resource Manager to deploy a new Microsoft SQL Server instance in a Microsoft Azure virtual machine (VM) that uses Premium storage. The combined initial size of the SQL Server user database files is expected to be over 200 gigabytes (GB). You must maximize performance for the database files and the log file.

You add the following additional drive volumes to the VM:

You have the following requirements:

✑ Maximize performance of the SQL Server instance.

✑ Use Premium storage when possible.

You need to deploy the SQL instance.

In the table below, identify the drive where you must store each SQL Server file type.

NOTE: Make only one selection in each column. Each correct selection is worth one point.

Hot Area:

    Correct Answer:

    Enable read caching on the disk(s) hosting the data files and TempDB.

    Do not enable caching on disk(s) hosting the log file. Host caching is not used for log files.

    Incorrect Answers:

    C, D: Avoid using operating system or temporary disks for database storage or logging.

Question 7 of 94

DRAG DROP -

You are building a new Always On Availability Group in Microsoft Azure. The corporate domain controllers (DCs) are attached to a virtual network named

ProductionNetwork. The DCs are part of an availability set named ProductionServers1.

You create the first node of the availability group and add it to an availability set named ProductionServers2. The availability group node is a virtual machine (VM) that runs Microsoft SQL Server. You attach the node to ProductionNetwork.

The servers in the availability group must be directly accessible only by other company VMs in Azure.

You need to configure the second SQL Server VM for the availability group.

How should you configure the VM? To answer, drag the appropriate configuration settings to the correct target locations. Each configuration setting may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

NOTE: Each correct selection is worth one point.

Select and Place:

    Correct Answer:

    Explanation;

    Box 1: ProductionNetwork -

    The virtual network is named ProductionNetwork.

    Box 2: None /Not Assigned -

    As the servers in the availability group must be directly accessible only by other company VMs in Azure, there should be no Public IP address.

    Box 3: ProductionServer2 -

    You create the first node of the availability group and add it to an availability set named ProductionServers2. The availability group node is a virtual machine (VM) that runs Microsoft SQL Server.

Question 8 of 94

HOTSPOT -

You plan to migrate a Microsoft SQL Server workload from an on-premises server to a Microsoft Azure virtual machine (VM). The current server contains 4 cores with an average CPU workload of 6 percent and a peak workload of 10 percent when using 2.4Ghz processors.

You gather the following metrics:

You need to design a SQL Server VM to support the migration while minimizing costs.

For each setting, which value should you use? To answer, select the appropriate storage option from each list in the answer area.

NOTE: Each correct selection is worth one point.

Hot Area:

    Correct Answer:

    Data drive: Premium Storage -

    Transaction log drive: Standard Storage

    TempDB drive: Premium Storage -

    Note: A standard disk is expected to handle 500 IOPS or 60MB/s.

    A P10 Premium disk is expected to handle 500 IOPS.

    A P20 Premium disk is expected to handle 2300 IOPS.

    A P30 Premium disk is expected to handle 5000 IOPS.

    VM size: A3 -

    Max data disk throughput is 8x500 IOPS

Question 9 of 94

You plan to migrate a database To Microsoft Azure SQL Database. The database requires 500 gigabytes (GB) of storage.

The database must support 50 concurrent logins. You must minimize the cost associated with hosting the database.

You need to create the database.

Which pricing tier should you use?

    Correct Answer: D

    D

    For a database size of 500 GB the Premium tier is required.

    Both P1 and P2 are adequate. P1 is preferred as it is cheaper.

    Note:

    Incorrect Answers:

    A, C: Maximum database size is 250 GB for the Standard pricing tier.

Question 10 of 94

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution. Determine whether the solution meets stated goals.

You manage a Microsoft SQL Server environment with several databases.

You need to ensure that queries use statistical data and do not initialize values for local variables.

Solution: You enable the PARAMETER_SNIFFING option for the databases.

Does the solution meet the goal?

    Correct Answer: B

    Enabling the PARAMETER_SNIFFING option allows SQL Server to use the parameter values during the first execution to create and cache the execution plan. This means that subsequent executions will use this cached execution plan, which is based on the initial parameter values, rather than statistical data. To meet the stated goal of ensuring that queries use statistical data and do not initialize values for local variables, disabling parameter sniffing would be more appropriate. Therefore, enabling the PARAMETER_SNIFFING option does not meet the goal.
