Microsoft Administering Relational Databases on Microsoft Azure Sample Questions (Q105-Q110):

NEW QUESTION # 105
You have 20 Azure SQL databases provisioned by using the vCore purchasing model.
You plan to create an Azure SQL Database elastic pool and add the 20 databases.
Which three metrics should you use to size the elastic pool to meet the demands of your workload? Each
correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

Answer: A,B,D

Explanation:
Section: [none]
Explanation:
CE: Estimate the vCores needed for the pool as follows:
For vCore-based purchasing model: MAX(<Total number of DBs X average vCore utilization per DB>,
<Number of concurrently peaking DBs X Peak vCore utilization per DB)
A: Estimate the storage space needed for the pool by adding the number of bytes needed for all the databases
in the pool.

NEW QUESTION # 106
Your company has an Azure SQL Database instance. This database is going to be added to a failover group. It has to be ensured that the database becomes available as quickly as possible if a major outage occurs. The Read/Write failover policy is set to Automatic.
Which of the following can occur as a result of this configuration? (Select TWO)

Answer: A,C

Explanation:
If you set the Read/Write failover policy as Automatic, in the event of a datacenter or Azure regional outage, the databases will failover automatically.
For Automatic failover, you can also set the Read/Write grace period as shown below.

Option B is incorrect because this is based on a dataceter or Azure regional outage Option C is incorrect since the policy is set as Automatic, so the databases can't be failed over manually.

NEW QUESTION # 108
You have a 50-TB Microsoft SQL Server database named DB1.
You need to reduce the time it takes to perform database consistency checks of DB1.
Which Transact-SQL 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:

Reference:
https://docs.microsoft.com/en-us/sql/t-sql/database-console-commands/dbcc-checkdb-transact-sql?view=sql- server-ver15 Basic Concept: This question tests plan and configure a high availability and disaster recovery (ha/dr) environment in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You need to reduce the time it takes to perform database consistency checks of DB1.
Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.


NEW QUESTION # 109
You have an Azure SQL database named db1.
You need to retrieve the resource usage of db1 from the last week.
How should you complete the statement? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

Explanation:

Box 1: sys.resource_stats
sys.resource_stats returns CPU usage and storage data for an Azure SQL Database. It has database_name and start_time columns.
Box 2: DateAdd
The following example returns all databases that are averaging at least 80% of compute utilization over the last one week.
DECLARE @s datetime;
DECLARE @e datetime;
SET @s= DateAdd(d,-7,GetUTCDate());
SET @e= GETUTCDATE();
SELECT database_name, AVG(avg_cpu_percent) AS Average_Compute_Utilization FROM sys.resource_stats WHERE start_time BETWEEN @s AND @e GROUP BY database_name HAVING AVG(avg_cpu_percent) >= 80 Reference:
