최신 Microsoft Azure DP-300 무료샘플문제 (Q252-Q257):

질문 # 252
You have an Azure Stream Analytics job.
You need to ensure that the job has enough streaming units provisioned.
You configure monitoring of the SU % Utilization metric.
Which two additional metrics should you monitor? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

정답:C,E

설명:
To react to increased workloads and increase streaming units, consider setting an alert of 80% on the SU Utilization metric. Also, you can use watermark delay and backlogged events metrics to see if there is an impact.
Note: Backlogged Input Events: Number of input events that are backlogged. A non-zero value for this metric implies that your job isn't able to keep up with the number of incoming events. If this value is slowly increasing or consistently non-zero, you should scale out your job, by increasing the SUs.

질문 # 253
You deploy an instance of SQL Server on Azure Virtual Machines named VM1.
You need to create a SQL Server Agent job that will rebuild indexes of the databases hosted on VM1. The solution must use the principle of least privilege.
What should you create first?

정답:B

설명:
With a system-assigned managed identity, Azure automatically creates an identity in Azure AD that is tied to the Azure VM instance. This allows you to grant the identity permissions to the specific resources that it requires, without having to manage credentials or rotate passwords.
Using a managed identity ensures that only the necessary permissions are granted to the job, which is in line with the principle of least privilege. The job can then use this managed identity to perform the required actions, such as rebuilding indexes.


질문 # 254
You have two Azure virtual machines named VM1 and VM2 that run Windows Server 2019. VM1 and VM2 each host a default Microsoft SQL Server 2019 instance. VM1 contains a database named DB1 that is backed up to a file named D:\DB1.bak.
You plan to deploy an Always On availability group that will have the following configurations:
VM1 will host the primary replica of DB1.
VM2 will host a secondary replica of DB1.
You need to prepare the secondary database on VM2 for the availability group.
How should you complete the Transact-SQL statement? To answer, select the appropriate options in the answer area.

정답:

질문 # 255
You have an Azure subscription that contains an instance of SQL Server on Azure Virtual Machines. The virtual machine hosts a database named DB1. You need to monitor DB1 by using Extended Events. The solution must meet the following requirements:
* Capture raw event data and store the data in Azure Storage.
* Minimize the performance impact of capturing extended events.
How should you complete the Transact-SQL statement? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

질문 # 256
You have an Azure subscription that contains an Azure SQL database named db1.
You need to implement SQL insights for db1.
Which two resources should you create first? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point

정답:B,E

설명:
Basic Concept: This question tests monitor, configure, and optimize database resources in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why B and D is Correct: a virtual machine is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation.
This fits the case because the requested outcome is: You need to implement SQL insights for db1. The selected feature addresses that outcome directly rather than relying on a workaround. a Log Analytics workspace matches the expected DP-300 administration action. Log Analytics stores logs and metrics in a queryable workspace and supports workbooks, dashboards, alerting, and cross-resource analysis. The question is not asking for a general Azure capability; it is asking for the feature that produces this result: You need to implement SQL insights for db1.
Why A is Wrong: an Azure logic app is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It is useful in other troubleshooting paths, but this scenario requires a more specific monitoring or optimization feature.
Why C is Wrong: an Azure function is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It does not expose the required metric, query history, wait/blocking signal, or tuning mechanism; using it would not give the administrator the evidence requested.
Why E is Wrong: a storage account is related to operational monitoring or tuning, but it must match the exact signal needed: query history, resource utilization, wait/blocking detail, or automatic remediation. It would produce a different operational signal than the one needed to investigate, alert, or tune the workload in this question.
