DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
Your Azure Synapse Analytics dedicated SQL pool is experiencing performance degradation. You suspect that the workload is generating excessive data movement due to suboptimal distribution. Which dynamic management view (DMV) should you query to identify queries that are causing significant data movement?

Correct answer & explanation
✓
sys.dm_pdw_exec_requests
Sys.dm_pdw_exec_requests shows query steps including data movement operations. Option A is wrong because sys.dm_pdw_node_status shows node health. Option C is wrong because sys.dm_pdw_errors shows error details. Option D is wrong because sys.dm_pdw_waits shows wait states.
