                                              Microsoft Administering Relational Databases on Microsoft Azure Sample Questions (Q388-Q393):

                                              NEW QUESTION # 388
                                              You have an Azure subscription that contains a Standard SKU Azure SQL database named DB1.
                                              You need to enable point-in-time recovery (PITR) backups for DBl. The solution must maximize how long the backups are retained. Which retention period should you configure?

                                              Answer: A

                                              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 B is Correct: 35 days is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. In this scenario, the important constraint is: You need to enable point-in-time recovery (PITR) backups for DBl. 35 days satisfies that constraint without adding an unrelated service or manual process.
                                              Why A is Wrong: seven days 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 is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.
                                              Why C is Wrong: 180 days 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 handles a different resilience pattern and would not deliver the failover or recovery behavior required here.
                                              Why D is Wrong: 365 days 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 is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.


                                              NEW QUESTION # 389
                                              You have several Azure SQL databases on the same Azure SQL Database server in a resource group named
                                              ResourceGroup1.
                                              You must be alerted when CPU usage exceeds 80 percent for any database. The solution must apply to any
                                              additional databases that are created on the Azure SQL server.
                                              Which resource type should you use to create the alert?

                                              Answer: A

                                              Explanation:
                                              Section: [none]
                                              Explanation:
                                              There are resource types related to application code, compute infrastructure, networking, storage + databases.
                                              You can deploy up to 800 instances of a resource type in each resource group.
                                              Some resources can exist outside of a resource group. These resources are deployed to the subscription,
                                              management group, or tenant. Only specific resource types are supported at these scopes.

                                              NEW QUESTION # 390
                                              You have SQL Server on an Azure virtual machine.
                                              You review the query plan shown in the following exhibit.

                                              For each of the following statements, select yes if the statement is true. Otherwise, select no.
                                              NOTE: Each correct selection is worth one point.

                                              Answer:

                                              Explanation:

                                              NEW QUESTION # 391
                                              You have an Azure SQL database named DB1.
                                              You need to identify long-running queries against DB1 by using an Extended Events session.
                                              Which event should you use to create the session?

                                              Answer: C

                                              Explanation:
                                              To identify long-running queries in an Azure SQL Database using Extended Events, the primary event to use is sql_statement_completed.

                                              NEW QUESTION # 392
                                              You have an Azure SQL Database server named sqlsrv1 that hosts 10 Azure SQL databases.
                                              The databases perform slower than expected.
                                              You need to identify whether the performance issue relates to the use of tempdb by Azure SQL databases on
                                              sqlsrv1.
                                              What should you do?

                                              Answer: D

                                              Explanation:
                                              Section: [none]
                                              Explanation:
                                              The diagnostics log outputs tempDB contention details. You can use the information as the starting point for
                                              troubleshooting.
                                              You can use the Intelligent Insights performance diagnostics log of Azure SQL Database to troubleshoot
                                              performance issues.

                                              ......

                                              DP-300 test questions have a mock examination system with a timing function, which provides you with the same examination environment as the real exam. Although some of the hard copy materials contain mock examination papers, they do not have the automatic timekeeping system. Therefore, it is difficult for them to bring the students into a real test state. With DP-300 Exam Guide, you can perform the same computer operations as the real exam, completely taking you into the state of the actual exam, which will help you to predict the problems that may occur during the exam, and let you familiarize yourself with the exam operation in advance and avoid rushing during exams.
