4 / 46
C. Azure Service Management
D. Microsoft identity platform
Answer: D
Explanation:
Scenario: To access the resources in Azure, App1 must use the managed identity of
the virtual machines that will host the app.
Managed identities provide an identity for applications to use when connecting to
resources that support Azure Active Directory (Azure AD) authentication. Applications
may use the managed identity to obtain Azure AD tokens.

Box 1: Azure AD Identity Protection
Azure AD Identity Protection helps you manage the roll-out of Azure AD Multi-Factor
Authentication (MFA) registration by configuring a Conditional Access policy to
require MFA registration no matter what modern authentication app you are signing in
to.
Scenario: Users that manage the production environment by using the Azure portal
must connect from a hybrid Azure AD-joined device and authenticate by using Azure
Multi-Factor Authentication (MFA).
