AZ-900 Describe Azure management and governance Practice Question
This AZ-900 practice question tests your understanding of describe azure management and governance. 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.
A company uses Azure Policy to require that all storage accounts must have blob soft delete enabled. They also want to automatically create a remediation task that fixes any existing non-compliant storage accounts. Which policy effect should they include in the policy definition to achieve automatic remediation?
Why wrong: The Deny effect blocks creation or update of non-compliant resources, but it does not remediate already existing non-compliant resources.
B
Audit
Why wrong: The Audit effect simply logs compliance state for resources. It does not trigger automatic remediation.
C
DeployIfNotExists
DeployIfNotExists creates a remediation task that deploys a configuration to make existing resources compliant. It is designed for automatic remediation of non-compliant resources.
D
Append
Why wrong: The Append effect adds additional fields to a resource during creation or update, but it is not used for remediation of existing resources in the same way as DeployIfNotExists.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DeployIfNotExists
The DeployIfNotExists effect is designed to automatically remediate non-compliant resources by deploying a defined template (e.g., enabling blob soft delete) when the resource is evaluated as non-compliant. This effect triggers a remediation task that can be run on existing resources, ensuring all storage accounts meet the policy requirement without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Deny
Why it's wrong here
The Deny effect blocks creation or update of non-compliant resources, but it does not remediate already existing non-compliant resources.
✗
Audit
Why it's wrong here
The Audit effect simply logs compliance state for resources. It does not trigger automatic remediation.
✓
DeployIfNotExists
Why this is correct
DeployIfNotExists creates a remediation task that deploys a configuration to make existing resources compliant. It is designed for automatic remediation of non-compliant resources.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'Audit' (which only reports) with 'DeployIfNotExists' (which actually fixes), or assume 'Deny' can retroactively fix existing resources, when it only blocks new non-compliant changes.
Detailed technical explanation
How to think about this question
Under the hood, DeployIfNotExists uses a linked ARM template (specified in the policy definition's 'deployment' property) that is executed via Azure Resource Manager when the policy evaluation identifies non-compliance. A subtle behavior is that the remediation task must be explicitly triggered (manually or via a schedule) after policy assignment; it does not run automatically on all existing resources at assignment time. In a real-world scenario, this is critical for enforcing security baselines across a large fleet of storage accounts without requiring a separate scripting solution.

TExam Day Tips
→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.
