Final answer:
With a Read-only lock on an Azure resource, an authorized user can remove the Read-only lock to change the resource. Other options like adding a Delete lock, making no changes, or changing to a Read/Write lock are not applicable.
Step-by-step explanation:
If an Azure resource has a Read-only lock, certain actions regarding the lock are permitted depending on the level of access the user has. Specifically:
- b) Remove the Read-only lock: A user with appropriate permissions (like an owner or user access administrator) can remove a Read-only lock from the resource. Once the lock is removed, the resource can be modified or deleted as necessary.
Options a), c), and d) are not correct because:
- You cannot add a Delete lock to a resource that already has a Read-only lock without removing the Read-only lock first.
- Changes can be made to the lock by an authorized user, which means that c) is not correct.
- Locks in Azure are either Read-only or Delete. There isn't a Read/Write lock, so option d) is not possible.
In conclusion, the correct answer is b) Remove the Read-only lock, assuming the user has the necessary permissions to do so.
