DP-300 Configure and manage automation of tasks Practice Question
Exhibit
Refer to the exhibit.
{ "type": "Microsoft.Sql/servers/databases", "apiVersion": "2022-05-01-preview", "properties": { "autoPauseDelay": 60, "minCapacity": 0.5, "zoneRedundant": false } }You are reviewing an ARM template snippet for an Azure SQL Database. The database should be configured to automatically pause after 60 minutes of inactivity and resume with a minimum capacity of 0.5 vCores. However, the database is not pausing as expected. What is the most likely cause?
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
✓
The database is not configured with the 'Serverless' compute tier.
Auto-pause functionality is only available for Azure SQL Database in the serverless compute tier. Without configuring the database as serverless (by setting the 'sku' property to include 'Serverless' tier), the auto-pause and auto-resume features will not work, regardless of other property settings. Option A is incorrect because the 'zoneRedundant' property does not affect auto-pause. Option C is incorrect because the minimum 'autoPauseDelay' for serverless is 60 minutes, not 360. Option D is incorrect because the API version used supports serverless features.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The 'zoneRedundant' property is set to false, which prevents auto-pause.
Why it's wrong here
Setting `zoneRedundant` to false has no bearing on auto-pause; the pause/resume behaviour belongs to the serverless compute tier, not the zone-redundancy setting. It tempts because zone redundancy genuinely affects availability configuration, and would be the right focus if the requirement were resilience across availability zones rather than inactivity-based pausing.
- ✓
The database is not configured with the 'Serverless' compute tier.
Why this is correct
Auto-pausing after inactivity and resuming at a minimum 0.5 vCores are exclusive to the serverless compute tier. Provisioned and hyperscale tiers never auto-pause, so the database must be serverless for the configured behaviour to take effect.
- ✗
The 'autoPauseDelay' value is too low; it must be at least 360 minutes.
Why it's wrong here
The 360-minute floor applies to serverless auto-pause only when the database sits on a General Purpose or Business Critical tier, not to the Hyperscale serverless configuration described. It is tempting because 360 minutes is a genuine minimum for some serverless deployments, so it would be the right answer if the stem specified General Purpose rather than Hyperscale.
- ✗
The API version does not support auto-pause.
Why it's wrong here
The API version governs resource schema and property availability, not the serverless auto-pause timer itself; pause behaviour is controlled by the `autoPauseDelay` property and the serverless compute tier, so an unsupported API version would fail template deployment outright rather than silently skip pausing. It tempts because older API versions genuinely omit newer properties, which is the correct diagnosis when a template rejects an unrecognised field.
