DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
Your Azure Synapse Analytics dedicated SQL pool is experiencing performance degradation. Queries that previously completed in seconds now take minutes. You suspect memory pressure and concurrency issues. What should you first review to diagnose the problem?
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
✓
sys.dm_pdw_exec_requests
Sys.dm_pdw_exec_requests provides a list of all currently executing or recent requests in the dedicated SQL pool, including their status, resource class, and elapsed time. This is the best first step to identify queries that may be causing memory pressure or concurrency issues. Option A (sys.dm_pdw_resource_waits) shows only resource waits but does not show the actual requests causing the waits. Option B (sys.dm_pdw_waits) shows wait information but lacks the direct request context needed for diagnosis. Option C (sys.dm_pdw_query_stats_xe) provides query execution statistics but not real-time active requests, so it is less suitable for immediate troubleshooting.
