The answer is Azure Resource Locks, which override RBAC to prevent accidental deletion. This is correct because Resource Locks apply a 'Deny' effect at the subscription, resource group, or resource level that cannot be bypassed by any RBAC role, including Owner or Contributor—meaning even a user with full administrative permissions cannot delete or modify a locked resource unless the lock itself is first removed by an Owner or User Access Administrator. On the Microsoft Azure Fundamentals AZ-900 exam, this distinction tests your understanding that RBAC controls who can act, while Resource Locks control what actions can be taken regardless of identity, often appearing in scenario-based questions where a Contributor accidentally deletes a critical resource. A common trap is assuming an Owner can always delete anything, but Resource Locks are the exception. Memory tip: think of a padlock on a door—no matter what key (RBAC role) you hold, you cannot open the door until the padlock (Resource Lock) is removed.
AZ-900 Describe Azure management and governance Practice Question

The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Which aspect of Azure governance ensures that resources are protected from accidental or unauthorized deletion regardless of RBAC role?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Resource Locks overriding RBAC
Azure Resource Locks override RBAC because they are applied at the subscription, resource group, or resource level and enforce a 'Deny' effect that cannot be bypassed by any RBAC role, including Owner. This ensures that even users with Contributor or Owner permissions cannot delete or modify a locked resource unless the lock is first removed by an Owner or User Access Administrator.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Azure RBAC deny assignments
Why it's wrong here
Deny assignments block specific RBAC actions; Resource Locks are a separate mechanism for protecting resources from modification/deletion.
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse Azure Policy's 'deny' effect with Resource Locks, not realizing that Policy only blocks non-compliant resource creation or updates, while Resource Locks block all delete or modify operations regardless of RBAC permissions.
Detailed technical explanation
How to think about this question
Resource Locks are implemented as a 'Deny' assignment in Azure's authorization system, which is evaluated after RBAC role assignments. This means that even if a user has an RBAC 'Allow' permission to delete a resource, the lock's 'Deny' takes precedence, effectively creating a 'NotDelete' or 'ReadOnly' constraint. In a real-world scenario, a production database could be protected with a 'CanNotDelete' lock so that even a compromised Owner account cannot accidentally drop the resource without first removing the lock, which itself requires Owner or User Access Administrator rights.

→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.
