Microsoft Administering Relational Databases on Microsoft Azure Sample Questions (Q13-Q18):

NEW QUESTION # 13
You are planning a solution that will use Azure SQL Database. Usage of the solution will peak from October
1 to January 1 each year.
During peak usage, the database will require the following:
* 24 cores
* 500 GB of storage
* 124 GB of memory
* More than 50,000 IOPS
During periods of off-peak usage, the service tier of Azure SQL Database will be set to Standard.
Which service tier should you use during peak usage?

Answer: C

Explanation:
Reference:
https://docs.microsoft.com/en-us/azure/azure-sql/database/resource-limits-vcore-single-databases#business- critical---provisioned-compute---gen4


NEW QUESTION # 14
You have an on-premises app named App1 that stores data in an on-premises Microsoft SQL Server 2016 database named DB1.
You plan to deploy additional instances of App1 to separate Azure regions. Each region will have a separate instance of App1 and DB1. The separate instances of DB1 will sync by using Azure SQL Data Sync.
You need to recommend a database service for the deployment. The solution must minimize administrative effort.
What should you include in the recommendation?

Answer: C

Explanation:
Azure SQL Database single database supports Data Sync.
Reference:
https://docs.microsoft.com/en-us/azure/azure-sql/database/features-comparison


NEW QUESTION # 15
You have an Azure SQL managed instance.
You need to restore a database named DB1 by using Transact-SQL.
Which command should you run? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

Explanation:


NEW QUESTION # 16
You have an Azure subscription that contains a logical SQL server named Server1.
The master database of Server1 contains a user named User1.
You need to ensure that User1 can create databases on Server1.
Which database role should you assign to User1?

Answer: B

Explanation:
dbmanager: Can create and delete databases. A member of the dbmanager role that creates a database, becomes the owner of that database, which allows that user to connect to that database as the dbo user. The dbo user has all database permissions in the database. Members of the dbmanager role don't necessarily have permission to access databases that they don't own.
Reference:

NEW QUESTION # 17
A data engineer creates a table to store employee information for a new application. All employee names are in the US English alphabet. All addresses are locations in the United States. The data engineer uses the following statement to create the table.

You need to recommend changes to the data types to reduce storage and improve performance.
Which two actions should you recommend? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

Answer: C,E

Explanation:
Basic Concept: This question tests performance optimization for SQL workloads, including Query Store, automatic tuning, index/statistics maintenance, and engine-level resource behavior.
Why A and E is Correct: Change Salary to the money data type. 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. In this scenario, the important constraint is: You need to recommend changes to the data types to reduce storage and improve performance. Change Salary to the money data type. satisfies that constraint without adding an unrelated service or manual process. Change LastHireDate to the date data type.
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. In this scenario, the important constraint is: You need to recommend changes to the data types to reduce storage and improve performance. Change LastHireDate to the date data type. satisfies that constraint without adding an unrelated service or manual process.
Why B is Wrong: Change PhoneNumber to the float data type. 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.
Why C is Wrong: Change LastHireDate to the datetime2(7) data type. 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 D is Wrong: Change PhoneNumber to the bigint data type. 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.
