Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

What is a setting that can be applied to any resource to block modification or deletion?

1. Resource Groups

2. Tags

3. Policies

4. Resource Locks

The correct answer is: Resource Locks

The correct answer is resource locks. Resource locks are a feature in Azure that provides a way to prevent accidental deletion or modification of Azure resources. When a resource lock is applied, it ensures that the resource cannot be altered or removed unless the lock is removed first. This is particularly useful for protecting critical resources that should not be changed or deleted without proper authorization. Resource groups, while useful for organizing resources, do not inherently have the capability to prevent modifications or deletions of resources within them. Tags are metadata attached to resources that help with organization and identification, but they do not enforce any restrictions on the resources themselves. Policies in Azure are used to enforce rules and governance over resources, such as compliance standards, but they do not specifically block modification or deletion like resource locks do. Therefore, resource locks are uniquely suited for safeguarding resources against unintended changes.
