Snowflake SnowPro Core Practice Test 5
Question 40
For an original SnowPro Core educational scenario, consider: A marketing dashboard surge occurs at 9 AM while an administrator is considering a permanently larger single cluster. Select TWO complementary steps: the targeted correction and its strongest prechange validation.
- Assume adding eight clusters makes a single serial query run eight times faster.
- Check: Inspect queued overload time, cluster count, concurrency and credit usage during a realistic peak.
- Change: Configure and evaluate an appropriate multi-cluster warehouse and scaling policy to absorb concurrent sessions.
- Check: Check retention settings, query timestamp and a before/after row sample before restoring.
- Change: Use permanent tables for durable recovery requirements and transient tables for suitable short-lived data with reduced recovery guarantees.
Explanation
Correct Answer
B:Additional clusters can reduce queuing under concurrency, but do not inherently accelerate one slow query. Acceptance: The peak workload completes with reduced queuing while the cluster count contracts after demand subsides.
C:Additional clusters can reduce queuing under concurrency, but do not inherently accelerate one slow query. Evidence: Inspect queued overload time, cluster count, concurrency and credit usage during a realistic peak.
Incorrect Answers
A:For this select two assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it. Additional clusters can reduce queuing under concurrency, but do not inherently accelerate one slow query.
D:Check: Check retention settings, query timestamp and a before/after row sample before restoring. Additional clusters can reduce queuing under concurrency, but do not inherently accelerate one slow query.
E:Change: Use permanent tables for durable recovery requirements and transient tables for suitable short-lived data with reduced recovery guarantees. Additional clusters can reduce queuing under concurrency, but do not inherently accelerate one slow query.
Question 41
A Snowflake engineer is examining this platform situation: A sandbox warehouse stays running overnight while no analysts submit queries, wasting credits. A proposed shortcut is: Keep a development warehouse running around the clock because stored tables become unavailable during suspension. What should the Snowflake engineer recommend as the narrowly scoped correction? Select ONE best answer.
- Keep a development warehouse running around the clock because stored tables become unavailable during suspension.
- Set workload-suitable AUTO_SUSPEND and AUTO_RESUME values and validate startup behavior and billing.
- Tune MIN_CLUSTER_COUNT, MAX_CLUSTER_COUNT and supported scaling policy against measured concurrency requirements.
- Let Snowflake manage compressed columnar micro-partitions for native table data and use pruning-aware design where necessary.
Explanation
Correct Answer
B:An idle warehouse can be suspended to stop compute consumption and resumed when authorized work requires it. Applied case: A sandbox warehouse stays running overnight while no analysts submit queries, wasting credits.
Incorrect Answers
A:An idle warehouse can be suspended to stop compute consumption and resumed when authorized work requires it. For this best change assessment, the shortcut changes or bypasses the necessary correctness, governance or operational boundary rather than correcting it.
C:Tune MIN_CLUSTER_COUNT, MAX_CLUSTER_COUNT and supported scaling policy against measured concurrency requirements. An idle warehouse can be suspended to stop compute consumption and resumed when authorized work requires it.
D:Let Snowflake manage compressed columnar micro-partitions for native table data and use pruning-aware design where necessary. An idle warehouse can be suspended to stop compute consumption and resumed when authorized work requires it.
Question 42
A Snowflake implementation review finds: A sandbox warehouse stays running overnight while no analysts submit queries, wasting credits. The team proposes: Set workload-suitable AUTO_SUSPEND and AUTO_RESUME values and validate startup behavior and billing. Which platform principle most strongly supports the recommended response? Select ONE best answer.
- Iceberg tables use external cloud object storage and Iceberg metadata rather than Snowflake's native managed storage layout.
- An idle warehouse can be suspended to stop compute consumption and resumed when authorized work requires it.
- Streams track table change offsets; consuming a stream in committed DML advances its position, so independent consumers need separate offsets.
- Standard Snowflake table storage is automatically organized into immutable columnar micro-partitions and their metadata rather than manually managed warehouse files.
Explanation
Correct Answer
B:Demonstrable success requires: Idle hours stop consuming warehouse compute and the next permitted query resumes processing as expected. Applied case: A sandbox warehouse stays running overnight while no analysts submit queries, wasting credits.

Question 44
A candidate correction has been tested and the platform team requires a post-change acceptance check. Original problem: A sandbox warehouse stays running overnight while no analysts submit queries, wasting credits. The service owner needs positive and negative results and evidence that legitimate data workflows still function. Which acceptance result demonstrates correct platform behavior without disrupting authorized workflows? Select ONE best answer.

- Change: Set workload-suitable AUTO_SUSPEND and AUTO_RESUME values and validate startup behavior and billing. Verify: Review warehouse configuration, idle duration and metered credit history around overnight gaps.

Question 46
A Snowflake engineer is examining this platform situation: A development team manually resumes its warehouse every morning after disabling automatic resume to reduce spending. A proposed shortcut is: Keep a development warehouse running around the clock because stored tables become unavailable during suspension. What should the Snowflake engineer recommend as the narrowly scoped correction? Select ONE best answer.
- Test a larger warehouse size for the memory- or compute-bound individual query and review profile improvement versus credits.
- Keep a development warehouse running around the clock because stored tables become unavailable during suspension.
- Select Snowsight for suitable interactive tasks and supported Snowflake connectors, drivers or CLI for automated access.
- Set workload-suitable AUTO_SUSPEND and AUTO_RESUME values and validate startup behavior and billing.
Explanation
Correct Answer
D:An idle warehouse can be suspended to stop compute consumption and resumed when authorized work requires it. This targeted change addresses the stated technical or governance gap without discarding necessary controls.
Incorrect Answers
A:This option addresses a different Snowflake technical topic (Warehouse resizing for resource-intensive queries) rather than the documented Warehouse auto-suspend and auto-resume decision.
B:An idle warehouse can be suspended to stop compute consumption and resumed when authorized work requires it. Use this instead: Set workload-suitable AUTO_SUSPEND and AUTO_RESUME values and validate startup behavior and billing.
C:Select Snowsight for suitable interactive tasks and supported Snowflake connectors, drivers or CLI for automated access. An idle warehouse can be suspended to stop compute consumption and resumed when authorized work requires it.
