Full question →mediummultiple choiceObjective-mapped
A company stores critical financial records in an Azure Storage account. The operations team needs to ensure that the storage account cannot be deleted by any user, including administrators with Contributor permissions. However, authorized users must still be able to add and modify blobs. The solution should not affect the ability to update the account's configuration. Which Azure feature should the company implement?
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
Assign the Storage Blob Data Owner role to the operations team.
This role grants full control over storage blob data, but it does not prevent deletion of the storage account itself. Users holding this role can still delete the account if they also have delete permissions at the storage account level.
B
Best answer
Apply a CanNotDelete resource lock on the storage account.
A CanNotDelete resource lock prevents the storage account from being deleted by any user or process, while allowing all other operations (such as reading and updating blobs) as long as the user has the necessary RBAC permissions. This meets the requirement exactly.
C
Distractor review
Create an Azure Policy that denies delete operations on storage accounts.
Azure Policy can enforce rules across resources, but it is not a direct resource lock. Policy effects like 'Deny' can block operations, but they apply at the subscription or management group scope and can be more complex to configure. Additionally, policy exclusions could potentially allow deletions. A resource lock is the simpler and more targeted solution.
D
Distractor review
Move the storage account to a new resource group.
Moving the storage account to a different resource group does not provide any protection against deletion. The storage account can still be deleted from the new resource group by users with appropriate permissions.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this AZ-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Apply a CanNotDelete resource lock on the storage account. — Resource locks are an Azure governance feature that prevent accidental deletion or modification of resources. A CanNotDelete lock ensures that the storage account cannot be deleted, while still allowing authorized users to read, write, and update blobs and configuration. Azure Policy can enforce rules but does not directly lock a resource; RBAC roles alone do not prevent deletion if a user has delete permissions. Moving the resource group does not provide deletion protection.
