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 wants to ensure that all Azure resources are tagged with a 'CostCenter' tag at creation time. If a resource is created without the tag, it should be automatically denied. Which Azure Policy effect should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A) deny
The 'deny' effect is correct because it actively blocks any resource creation request that does not include the required 'CostCenter' tag. Azure Policy with the 'deny' effect evaluates the resource against the policy rule at creation or update time and rejects the request if the condition is not met, ensuring compliance before the resource is provisioned.
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.
✓
A) deny
Why this is correct
The deny effect prevents resources from being created if they do not comply with the policy condition.

✗
B) audit
Why it's wrong here
Audit only logs non-compliant resources; it does not block their creation.
✗
C) append
Why it's wrong here
Append adds the missing tag but does not deny creation if the tag cannot be added.
✗
D) deployIfNotExists
Why it's wrong here
DeployIfNotExists deploys additional resources to correct non-compliance, but does not block the original resource creation.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'deny' with 'audit' or 'append', thinking that logging or auto-tagging is sufficient to enforce compliance, but only 'deny' actively prevents the resource from being created in the first place.
Detailed technical explanation
How to think about this question
Azure Policy effects are evaluated in a specific order during resource creation: 'deny' is checked first and can short-circuit the request, returning an HTTP 403 Forbidden status to the caller. The 'deny' effect uses Azure Resource Manager's role-based access control (RBAC) to enforce the block, meaning even if a user has Contributor permissions, the policy overrides the action. In a real-world scenario, a company might combine 'deny' with 'audit' to both block non-compliant resources and log attempts for security monitoring.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
