This AZ-104 practice question tests your understanding of manage azure identities and governance. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
You need to prevent accidental deletion of a production resource group while still allowing administrators to update resources inside it. What should you apply to the resource group?
A ReadOnly lock
Why wrong: A ReadOnly lock would prevent updates, which does not meet the requirement.
A CanNotDelete lock
A CanNotDelete lock prevents accidental deletion while still allowing updates.
A deny assignment
Why wrong: A deny assignment is not the standard simple mechanism for this requirement.
A budget alert
Why wrong: A budget alert only monitors spending.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
A CanNotDelete lock
A CanNotDelete lock (B) prevents the resource group from being deleted while still allowing all operations (including updates) on resources within it. This is the correct choice because the requirement is to block accidental deletion of the entire resource group, not to restrict modifications to its resources.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
A ReadOnly lock
Why it's wrong here
A ReadOnly lock would prevent updates, which does not meet the requirement.
A CanNotDelete lock
Why this is correct
A CanNotDelete lock prevents accidental deletion while still allowing updates.

A deny assignment
Why it's wrong here
A deny assignment is not the standard simple mechanism for this requirement.
A budget alert
Why it's wrong here
A budget alert only monitors spending.
Common exam traps
The trap here is that candidates often confuse a ReadOnly lock with a CanNotDelete lock, assuming that preventing deletion requires a more restrictive lock, but the correct lock is the one that specifically targets deletion only.
Detailed technical explanation
Azure resource locks operate at the management plane level, applying to all users and roles regardless of RBAC permissions. A CanNotDelete lock uses the Microsoft.Authorization/locks resource type and is inherited by all child resources within the scope, meaning it blocks DELETE calls to the resource group itself but allows PUT, PATCH, and POST operations on its resources. In a real-world scenario, this is critical for production environments where you want to prevent accidental removal of the entire group while still allowing DevOps teams to deploy updates.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
