}Refer to the exhibit. You are reviewing the workload classifier configuration for an Azure Synapse Analytics dedicated SQL pool. You notice that the 'HeavyLoader' classifier has a queryExecutionTimeoutSeconds of 0. What is the implication of this setting?
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
✓
Queries classified as 'HeavyLoader' will not have a timeout.
When queryExecutionTimeoutSeconds is set to 0, it means no timeout is enforced. Queries classified as 'HeavyLoader' can run indefinitely without being terminated by the timeout mechanism. Option A is incorrect because a value of 0 does not mean indefinite waiting for resources; it refers to the timeout duration. Option B is incorrect; 0 is a valid configuration that disables the timeout. Option D is incorrect; a timeout of 0 does not cause immediate timeout but rather no timeout.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Queries classified as 'HeavyLoader' will wait indefinitely for resources.
Why it's wrong here
A queryExecutionTimeoutSeconds value of 0 disables the timeout, so classified queries are not terminated for exceeding a duration limit; it does not govern resource waiting. The setting targets capping long-running query execution, not controlling concurrency queueing behaviour.
- ✗
The configuration is invalid; queryExecutionTimeoutSeconds must be greater than 0.
Why it's wrong here
Zero is a valid value for queryExecutionTimeoutSeconds, meaning queries run without a time limit rather than being rejected at configuration time. It is tempting because other timeout parameters require positive integers, so a zero looks like a validation error, but Synapse treats zero here as unlimited execution time.
- ✓
Queries classified as 'HeavyLoader' will not have a timeout.
Why this is correct
A queryExecutionTimeoutSeconds value of zero disables the timeout entirely, so 'HeavyLoader' queries run until completion or manual cancellation. This satisfies the stem's scenario by confirming that the classifier imposes no execution time limit, unlike classifiers with a positive value that terminate queries after the specified seconds.
- ✗
Queries classified as 'HeavyLoader' will timeout immediately.
Why it's wrong here
Zero disables the timeout entirely, so classified queries run until completion rather than being cancelled at once. It is tempting because zero often signals an immediate expiry in scheduling contexts, but here the value means no limit, which is the correct choice when long-running HeavyLoader batches must not be terminated.
