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. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 organization uses Azure Synapse Analytics serverless SQL pool to query data in Azure Data Lake Storage Gen2. You notice that queries are taking longer than expected. You need to identify which queries are consuming the most resources and optimize them. What should you do first?
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Query the sys.dm_exec_requests DMV to view running queries and their resource usage.
Option A is correct because DMVs like sys.dm_exec_requests provide real-time resource consumption for serverless SQL pool. Option B is wrong because query hints may help but you need to identify problematic queries first. Option C is wrong because diagnostic settings send logs to Log Analytics, but DMVs are immediate. Option D is wrong because statistics are already maintained by the serverless pool.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use query hints to optimize execution plans.
Why it's wrong here
Hints require knowing which queries to optimize.
✓
Query the sys.dm_exec_requests DMV to view running queries and their resource usage.
Why this is correct
DMVs give real-time insight into resource consumption.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Enable diagnostic settings and send query logs to Log Analytics.
Why it's wrong here
Logs are for historical analysis, not immediate.
✗
Create statistics on all columns used in queries.
Why it's wrong here
Serverless SQL pool auto-creates statistics.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
