The answer is to enable result set caching for the database. This feature directly addresses the need for Azure Synapse result set caching for query performance by storing the complete output of a query in the Synapse cache, so when the same query is run again against the frequently accessed fact table, the results are served instantly from cache without re-scanning the underlying data. This not only speeds up repeated queries but also reduces resource contention, ensuring other workloads are not impacted. On the Microsoft Azure Data Fundamentals DP-900 exam, this question tests your understanding of dedicated SQL pool performance features; a common trap is confusing result set caching with materialized views, which require manual maintenance and storage, or with workload classification, which only prioritizes resources. Remember the memory tip: “Cache the result, don’t re-scan the column.”
DP-900 Describe an analytics workload on Azure Practice Question
This DP-900 practice question tests your understanding of describe an analytics workload on azure. 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 company uses Azure Synapse Analytics to run analytical queries on large datasets. You need to ensure that queries against a frequently accessed fact table perform well without impacting other workloads. Which feature should you use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable result set caching for the database.
Option C is correct. Result set caching stores query results in the Synapse cache, speeding up repeated queries and reducing resource contention. Option A is wrong because materialized views require upfront storage and maintenance. Option B is wrong because workload classification prioritizes, not caches. Option D is wrong because splitting tables increases complexity.
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.
✗
Create materialized views on the fact table.
Why it's wrong here
Materialized views are pre-computed but still consume storage and need maintenance.
✓
Enable result set caching for the database.
Why this is correct
Result set caching stores query results for repeated execution without recomputation.
Related concept
Read the scenario before looking for a memorised answer.
✗
Partition the fact table by a frequently filtered column.
Why it's wrong here
Partitioning improves scan performance but not as effective as caching for repeated queries.
✗
Use workload classification to prioritize the queries.
Why it's wrong here
Prioritization does not cache results; it only assigns resources.
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.
