Which feature helps prevent accidental deletion of a critical resource?

Resource Locks prevent accidental deletion or modification of Azure resources. You can apply "CanNotDelete" locks to prevent deletion, or "ReadOnly" locks to prevent any changes. This is crucial for critical resources like production databases or virtual networks. Azure Blueprint helps manage compliance and consistency across subscriptions, but doesn't directly prevent accidental deletion. Azure Advisor provides recommendations for optimizing resources, security, and cost, but doesn't enforce actions. RBAC (Role-Based Access Control) manages who has access to perform actions on resources, but a user with delete permissions could still accidentally delete a resource if no lock is in place.
