DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
Which THREE features should you use to optimize query performance in Azure Synapse Analytics dedicated SQL pool? (Choose three.)
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
✓
Materialized views.
Options C, D, and E are correct. Materialized views precompute and store aggregated data, reducing compute for complex queries. Workload management with workload groups and importance allocates resources and prioritizes critical queries. Result-set caching stores the results of repeated queries, eliminating recomputation. Option A (T-SQL views) is a logical abstraction and does not inherently optimize performance. Option B (geo-redundant storage) provides disaster recovery but does not affect query performance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
T-SQL views.
Why it's wrong here
T-SQL views are logical and do not improve performance.
- ✗
Geo-redundant storage (GRS).
Why it's wrong here
GRS is for disaster recovery, not performance.
- ✓
Materialized views.
Why this is correct
Materialized views precompute and store results for faster queries.
- ✓
Workload management with workload groups and importance.
Why this is correct
Workload management prioritizes and isolates resources for critical queries.
- ✓
Result-set caching.
Why this is correct
Caching stores query results for subsequent executions.
