NEW QUESTION # 58
You have an Azure SQL database named db1 on a server named server1.
The Intelligent Insights diagnostics log identifies that several tables are missing indexes.
You need to ensure that indexes are created for the tables.
What should you do?
Answer: C
Explanation:
Reference:
https://docs.microsoft.com/en-us/azure/azure-sql/database/automatic-tuning-overview Basic Concept: This question tests performance optimization for SQL workloads, including Query Store, automatic tuning, index/statistics maintenance, and engine-level resource behavior.
Why C is Correct: Automatic tuning uses built-in recommendations and verification to create/drop indexes or force last known good plans where supported. The scenario asks for: You need to ensure that indexes are created for the tables. That makes Modify the automatic tuning settings for db1. the option that satisfies the required Azure SQL layer and operational outcome.
Why A is Wrong: RuntheDBCC SQLPERF command. 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 B is Wrong: Run the dbcc dbreindex command. 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 D is Wrong: Query Store captures query text, plans, and runtime statistics, making it central for reviewing query history and troubleshooting plan regressions. It is useful in other troubleshooting paths, but this scenario requires a more specific monitoring or optimization feature.
NEW QUESTION # 59
Hotspot Question
You have an Azure subscription that contains an Azure SQL database.
The database fails to respond to queries in a timely manner.
You need to identify whether the issue relates to resource_semaphore waits.
How should you complete the Transact-SQL query? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
If your top wait type is RESOURCE_SEMAHPORE and you don't have a high CPU usage issue, you may have a memory grant waiting issue.
Determine if a RESOURCE_SEMAHPORE wait is a top wait
Use the following query to determine if a RESOURCE_SEMAHPORE wait is a top wait SELECT wait_type, SUM(wait_time) AS total_wait_time_ms FROM sys.dm_exec_requests AS req JOIN sys.dm_exec_sessions AS sess ON req.session_id = sess.session_id WHERE is_user_process = 1 - GROUP BY wait_type - ORDER BY SUM(wait_time) DESC; Reference:

NEW QUESTION # 60
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:
https://docs.microsoft.com/en-us/sql/relational-databases/system-catalog-views/sys-resource-stats-azure-sql-database 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 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 retrieve the resource usage of db1 from the last week.
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 # 61
You have an Azure Data Factory that contains 10 pipelines.
You need to label each pipeline with its main purpose of either ingest, transform, or load. The labels must be available for grouping and filtering when using the monitoring experience in Data Factory.
What should you add to each pipeline?
Answer: E
Explanation:
Explanation
Azure Data Factory annotations help you easily filter different Azure Data Factory objects based on a tag. You can define tags so you can see their performance or find errors faster.
