A gannet-cliff camera site has sign-in code ready but no directory application object yet. What Microsoft identity platform step must the developer complete before MSAL can sign users in?
Select an answer to reveal the explanation.
Short Explanation
MSAL needs an app registration the way a badge printer needs an employee record—client ID, redirect URI, and a credential. Bastion and Defender are ops/security products; a resource group alone is not an identity.
Full Explanation
An app registration on the Microsoft identity platform creates the application identity (application/client ID), redirect URIs, and credentials used by MSAL sign-in flows. Networking jump boxes and Defender plans are not substitutes for registration. Resource groups organize Azure resources; they do not register OAuth clients.
