A company uses Azure Policy to enforce governance. They want to prevent users from creating virtual machines of the Standard_DS3_v2 SKU in their subscription, and they also want to log any attempt to create such a VM (whether successful or not) for audit purposes. What is the minimum number of Azure Policy assignments required to meet both requirements?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
One – assign a policy definition with the Deny effect.
A single Deny effect prevents creation but does not produce a separate compliance state for audit purposes; it only logs a denial event. The requirement explicitly asks for logging attempts for audit, which is more clearly satisfied by an Audit effect.
B
Distractor review
One – assign a policy definition with the Audit effect.
An Audit effect logs the attempt and shows compliance state, but it does not block the creation of the VM. The requirement also includes preventing the VM from being created.
C
Best answer
Two – assign one policy definition with the Deny effect and another with the Audit effect.
Assigning two policies, one with Deny and one with Audit, simultaneously blocks forbidden VM SKU creation and provides a clear compliance view of all attempts (both successful and blocked) for auditing. This is the minimum configuration to satisfy both requirements.
D
Distractor review
Two – assign one policy definition with the Deny effect and another with the Append effect.
The Append effect adds tags or settings but does not log attempts for audit. Combining Deny with Append still does not address the logging/audit requirement.
Common exam trap
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Technical deep dive
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.

FAQ
Questions learners often ask
What does this AZ-900 question test?
Standard ACLs match source addresses.
What is the correct answer to this question?
The correct answer is: Two – assign one policy definition with the Deny effect and another with the Audit effect. — The Deny effect blocks the creation of non-compliant resources, and the Audit effect logs the attempt and flags the resource as non-compliant without blocking it. To both block and log such attempts, the company must assign two separate policy definitions: one with the Deny effect and another with the Audit effect. A single Deny assignment logs the denial event in the activity log but does not provide the explicit compliance state in the Policy compliance dashboard for the desired audit view. A single Audit assignment only logs and does not block. The Append effect adds tags or properties but does not block or audit the creation attempt.
