You plan to deploy an application named App1 that will run on five Azure virtual machines. Additional virtual machines will be deployed later to run App1.
You need to recommend a solution to meet the following requirements for the virtual machines that will run App1:
✑ Ensure that the virtual machines can authenticate to Azure Active Directory (Azure AD) to gain access to an Azure key vault, Azure Logic Apps instances, and an Azure SQL database.
✑ Avoid assigning new roles and permissions for Azure services when you deploy additional virtual machines.
✑ Avoid storing secrets and certificates on the virtual machines.
✑ Minimize administrative effort for managing identities.
Which type of identity should you include in the recommendation?
A. a service principal that is configured to use a certificate
B. a system-assigned managed identity
C. a service principal that is configured to use a client secret
D. a user-assigned managed identity
Managed identities for Azure resources is a feature of Azure Active Directory.
User-assigned managed identity can be shared. The same user-assigned managed identity can be associated with more than one Azure resource.
B: System-assigned managed identity cannot be shared. It can only be associated with a single Azure resource.
