Microsoft Administering Relational Databases on Microsoft Azure Sample Questions (Q140-Q145):

NEW QUESTION # 140
You have an Azure Data Factory pipeline that is triggered hourly.
The pipeline has had 100% success for the past seven days.
The pipeline execution fails, and two retries that occur 15 minutes apart also fail. The third failure returns the following error.

What is a possible cause of the error?

Answer: C

Explanation:
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 is Correct: The parameter used to generate year=2021/month=01/day=10/hour=06 was incorrect. 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. The scenario asks for: You have an Azure Data Factory pipeline that is triggered hourly. That makes The parameter used to generate year=2021/month=01
/day=10/hour=06 was incorrect. the option that satisfies the required Azure SQL layer and operational outcome.
Why A is Wrong: From 06:00 to 07:00 on January 10, 2021, there was no data in wwi/BIKES/CARBON. 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: From 06:00 to 07:00 on January 10, 2021, the file format of data in wwi/BIKES/CARBON was incorrect. 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 D is Wrong: The pipeline was triggered too early. 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.


NEW QUESTION # 141
You have an Azure subscription.
You need to deploy two instances of SQL Server on Azure virtual machines in a highly available configuration that will use an Always On availability group. The solution must meet the following requirements:
- Minimize how long it takes to fail over.
- Maintain existing connections to the primary replica during a
failover.
What should you do?

Answer: C

Explanation:
To match the on-premises experience for connecting to your availability group listener, deploy your SQL Server VMs to multiple subnets within the same virtual network. Having multiple subnets negates the need for the extra dependency on an Azure Load Balancer, or a distributed network name (DNN) to route your traffic to your listener. ref: https://learn.microsoft.com/en- us/azure/azure-sql/virtual-machines/windows/availability-group-overview?view=azuresql- vm#connectivity


NEW QUESTION # 142
You have an Azure subscription.
You need to deploy an Azure SQL resource that will support cross database queries by using an Azure Resource Manager (ARM) template.
How should you complete the ARM template? To answer, select the appropriate options in the answer area.

NEW QUESTION # 143
You have SQL Server on an Azure virtual machine named SQL1.
SQL1 has an agent job to back up all databases.
You add a user named dbadmin1 as a SQL Server Agent operator.

Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Answer:

Explanation:

1 - Enable the email settings for the SQL Server Agent
2 - Create a job alert
3 - Create a job notification

NEW QUESTION # 144
You have the following Transact-SQL query.

Which column returned by the query represents the free space in each file?

Answer: D

Explanation:
Example:
Free space for the file in the below query result set will be returned by the FreeSpaceMB column.
SELECT DB_NAME() AS DbName,
name AS FileName,
type_desc,
size/128.0 AS CurrentSizeMB,
size/128.0 - CAST(FILEPROPERTY(name, 'SpaceUsed') AS INT)/128.0 AS FreeSpaceMB FROM sys.database_files WHERE type IN (0,1); Reference:
