This AZ-104 practice question tests your understanding of manage azure identities 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.
You need to prevent accidental deletion of a resource group while still allowing administrators to create and modify resources inside it. Which Azure lock should you apply?
ReadOnly
Why wrong: A ReadOnly lock would prevent modifications as well as deletion.
CanNotDelete
A CanNotDelete lock prevents deletion while still permitting updates.
Delete lock
Why wrong: Delete lock is not the Azure lock type name.
No lock and a budget alert
Why wrong: A budget alert does not prevent deletion.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
CanNotDelete
The CanNotDelete lock prevents deletion of the resource group while still allowing all operations (read, write, modify) on resources within it. This lock type is designed specifically to protect against accidental deletion without restricting administrative actions like creating or updating 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.
ReadOnly
Why it's wrong here
A ReadOnly lock would prevent modifications as well as deletion.
CanNotDelete
Why this is correct

Delete lock
Why it's wrong here
Delete lock is not the Azure lock type name.
No lock and a budget alert
Why it's wrong here
A budget alert does not prevent deletion.
Common exam traps
The trap here is that candidates confuse the CanNotDelete lock with the ReadOnly lock, mistakenly thinking ReadOnly still allows modifications, or they invent a non-existent 'Delete lock' option because it sounds plausible.
Detailed technical explanation
Azure locks are applied at the management group, subscription, resource group, or resource scope and are inherited by all child resources. The CanNotDelete lock uses Azure Resource Manager's authorization system to block DELETE operations at the specified scope while allowing all other operations (GET, PUT, PATCH). This lock is enforced even for users with Owner permissions, making it a critical governance tool for protecting production environments from accidental deletion.
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.
