Question
What should you use to associate the same identity to more than one Azure virtual machine?
A. an Azure AD user account
B. a user-assigned managed identity
C. a system-assigned managed identity
D. an Azure AD security group
Answer
B. a user-assigned managed identity
Explanation
A user-assigned managed identity is a standalone Azure resource that can be assigned to one or more Azure service instances. It allows you to associate the same identity with multiple Azure resources, including virtual machines.
Unlike system-assigned managed identities, which are tied to the lifecycle of a single Azure resource instance, user-assigned managed identities are reusable and can be assigned, removed, and reassigned to different resources as needed. This makes user-assigned managed identities a flexible option when you need to share the same identity across multiple resources, such as virtual machines.
By assigning a user-assigned managed identity to your Azure virtual machines, you can grant them the necessary permissions to access other Azure resources or services that support Azure Active Directory authentication, without the need to manage credentials or share secrets.
