Designing Azure Infrastructure Solutions — Question 23

You are designing a point of sale (POS) solution that will be deployed across multiple locations and will use an Azure Databricks workspace in the Standard tier. The solution will include multiple apps deployed to the on-premises network of each location.

You need to configure the authentication method that will be used by the app to access the workspace. The solution must minimize the administrative effort associated with staff turnover and credential management.

What should you configure?

Answer options

• A. a managed identity
• B. a service principal
• C. a personal access token

Correct answer: B

Explanation

A service principal is the correct choice as it provides a secure way to authenticate applications without needing to manage user credentials. A managed identity is typically used for Azure services to interact with other Azure resources, and a personal access token is not ideal for applications as it requires manual management of tokens, which can lead to issues with staff turnover.
