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

This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

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?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.

A
sys.dm_pdw_resource_waits
Why wrong: Shows resource waits aggregated, not current queries
B
sys.dm_pdw_waits
Why wrong: Shows waits, not active queries
C
sys.dm_pdw_query_stats_xe
Why wrong: Shows query execution statistics, not current state
D
sys.dm_pdw_exec_requests
Shows currently running queries with resource consumption

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

Option D is correct because 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.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
