DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing

You are monitoring an Azure Synapse Analytics dedicated SQL pool using dynamic management views (DMVs). You want to identify queries that are experiencing excessive memory grants causing concurrency issues. Which DMV should you query?

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) is correct because it contains the total_request_memory_granted column, which can be used to identify queries with excessive memory grants contributing to concurrency issues. Option A (sys.dm_pdw_waits) only shows wait types, not memory grants. Option C (sys.dm_pdw_resource_waits) shows resource wait statistics but not actual grant amounts. Option D (sys.dm_pdw_workload_management_workload_groups_details) provides workload group configuration and metrics, not per-query memory grant details.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • sys.dm_pdw_waits

    Why it's wrong here

    sys.dm_pdw_waits displays wait details but does not show memory grant values.

  • sys.dm_pdw_exec_requests

    Why this is correct

    Correct. sys.dm_pdw_exec_requests includes columns for memory grants, allowing identification of memory-heavy queries.

  • sys.dm_pdw_resource_waits

    Why it's wrong here

    sys.dm_pdw_resource_waits shows resource class membership, not actual memory grants per query.

  • sys.dm_pdw_workload_management_workload_groups_details

    Why it's wrong here

    sys.dm_pdw_workload_management_workload_groups_details shows workload group settings, not the memory grants of individual queries.
