DP-300 Practice Question: Monitor, configure, and optimize database resources
Which TWO methods can you use to monitor Azure SQL Database wait statistics?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Query sys.dm_os_wait_stats
Options A and E are correct. Querying sys.dm_os_wait_stats (A) directly provides cumulative wait statistics at the instance level. Query Store wait statistics reports (E) offer a query-focused view of wait statistics over time. Option B is incorrect because Azure Monitor Alerts are for setting notifications based on metrics or logs, not for monitoring wait statistics directly. Option C is incorrect because sys.dm_exec_query_stats shows execution statistics like CPU and duration, not wait types. Option D is incorrect because 'Dynamic Management Views' is a broad category, not a specific method; while some DMVs relate to waits, the generic term is not a valid answer.
