Question 1 Hotspot

HOTSPOT

You are designing a cost-optimized solution that uses Azure Batch to run two types of jobs on Linux nodes.

Question 3 Single choice

Your company deploys several virtual machines on-premises and to Azure. ExpressRoute is deployed and configured for on-premises to Azure connectivity.

Several virtual machines exhibit network connectivity issues.

You need to analyze the network traffic to identify whether packets are being allowed or denied from Azure to the virtual machines.

Solution: Install and configure the Azure Monitoring agent and the Dependency Agent on all the virtual machines. Use VM insights in Azure Monitor to analyze the network traffic.

Does this meet the goal?

  1. A

    Yes

  2. B

    No

Show answer and explanation

Correct answer: B

Question 4 Single choice

You have an app named App1 that uses two on-premises Microsoft SQL Server databases named DB1 and DB2.

You plan to migrate DB1 and DB2 to Azure.

You need to recommend an Azure solution to host DB1 and DB2.

The solution must meet the following requirements:

1. Support server-side transactions across DB1 and DB2.
2. Minimize administrative effort to update the solution.

What should you recommend?

  1. A

    two SQL Server databases on an Azure virtual machine

  2. B

    two Azure SQL databases on different Azure SQL Database servers

  3. C

    two Azure SQL databases in an elastic pool

  4. D

    two Azure SQL databases on the same Azure SQL Database managed instance

Show answer and explanation

Correct answer: D

Explanation

An Azure SQL Managed Instance is a fully managed SQL Server Database Engine hosted in Azure that provides most of the SQL Server capabilities. It supports features like cross-database queries and transactions, which is crucial for your requirement of supporting server-side transactions across DB1 and DB2. Additionally, since it's a fully managed solution, it minimizes the administrative effort needed to update and maintain the system.

Question 5 Hotspot

HOTSPOT

You have an on-premises web server farm that contains 10 servers. The servers run Windows Server 2016 and host a .NET Framework application named Appl. The state data for App1 is maintained by using a database named DB1. The usage patterns of App1 vary significantly.

You plan to perform the following actions:

1. Migrate App1 to Azure.
2. Migrate DB1 to an Azure SQL database.

You need to recommend a virtual machine-based solution to host App1. The solution must meet the following requirements:

1. Minimize how long it takes to scale out resources during surges in demand for App1.
2. Ensure minimum capacity availability of the virtual machines at all times.
3. Ensure that the solution can be recovered if an Azure region fails.
4. Minimize compute costs.

What should you include in the recommendation? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.
