- A
Azure Policy with the 'Deny' effect
Why wrong: The 'Deny' effect would block the creation of any resource that does not have the 'Department' tag. This is not what the team wants because they want the resource to be created and the tag to be automatically added, not blocked.
- B
Azure Policy with the 'Append' effect
The 'Append' effect is designed to automatically add specified fields (such as tags) to a resource during creation or update. This meets the requirement because the tag is applied without blocking resource creation.
- C
Azure Resource Lock
Why wrong: Azure Resource Locks are used to prevent accidental deletion or modification of resources. They do not automatically add tags or enforce tagging policies.
- D
Azure role-based access control (RBAC) with a custom role
Why wrong: Azure RBAC manages permissions for who can perform actions on resources. It does not automatically add tags to resources during creation. A custom role could be created, but it cannot automatically apply tags; it only grants or denies permissions.
Quick Answer
The answer is Azure Policy with the Append effect. This is the correct choice because Append automatically adds the ‘Department’ tag with a default value of ‘Finance’ to a resource during creation or update without blocking the operation, modifying the resource request to include the missing tag and ensuring compliance without interrupting the creation process. On the Microsoft Azure Fundamentals AZ-900 exam, this scenario tests your understanding of how Azure Policy effects differ: Append adds missing properties, while Deny blocks non-compliant resources entirely. A common trap is confusing Append with the DeployIfNotExists effect, which applies changes after creation rather than during it. Remember the memory tip: “Append adds, Deny ends”—if you need to enforce a default tag without stopping resource creation, Append is your go-to effect.
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 has an Azure subscription with multiple resource groups. The governance team wants to ensure that every new resource created in the subscription automatically receives a 'Department' tag with a default value of 'Finance' if the creator did not specify one. The team wants the tag to be applied without blocking the creation of the resource. Which Azure feature should they use?
Answer choices
Why each option matters

Correct answer & explanation
Azure Policy with the 'Append' effect
Azure Policy with the 'Append' effect is the correct choice because it adds the 'Department' tag with a default value of 'Finance' to a resource during creation or update, without blocking the operation. Unlike 'Deny', which prevents non-compliant resources, 'Append' modifies the resource request to include the missing tag, ensuring compliance without interrupting the creation process.
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.
- ✗
Azure Policy with the 'Deny' effect
Why it's wrong here
The 'Deny' effect would block the creation of any resource that does not have the 'Department' tag. This is not what the team wants because they want the resource to be created and the tag to be automatically added, not blocked.
- ✓
Azure Policy with the 'Append' effect
Why this is correct
The 'Append' effect is designed to automatically add specified fields (such as tags) to a resource during creation or update. This meets the requirement because the tag is applied without blocking resource creation.

Azure RBAC manages permissions for who can perform actions on resources. It does not automatically add tags to resources during creation. A custom role could be created, but it cannot automatically apply tags; it only grants or denies permissions.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'Append' with 'Deny', assuming that enforcing a tag requires blocking non-compliant resources, but 'Append' silently adds the missing tag without interrupting the creation flow.
Detailed technical explanation
How to think about this question
The 'Append' effect works by injecting additional fields into the resource's properties during the PUT or PATCH request, before the resource provider processes it. This is implemented via Azure Policy's evaluation engine, which intercepts the request and applies the effect if the condition (e.g., missing tag) is met. In a real-world scenario, if a creator specifies a different 'Department' tag value, 'Append' will not overwrite it unless the policy uses 'Append' with a condition that checks for the absence of the tag, ensuring only default values are added.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A company has a policy that all Azure resources must have an 'Owner' tag. They want to automatically add the 'Owner' tag with a value 'Default' to any resource created without it. Which Azure Policy effect should they use?
medium- ✓ A.Append
- B.Modify
- C.Deny
- D.Audit
Why A: The Append effect is correct because it allows Azure Policy to add the 'Owner' tag with a value 'Default' to any resource that is created without that tag. Append works by adding specified fields (like tags) to the resource during creation or update, without blocking the operation. This ensures compliance with the tagging policy automatically, without denying the resource creation.
