- Inspect role definitions, active assignments and role audit events for tenant administrators.
Explanation
Correct Answers
A:Require an additional authentication factor for relevant user sign-ins using supported Entra MFA methods. This is the directly applicable response. MFA combines different factor categories to reduce account takeover from a stolen password alone.
D:Inspect authentication method registration, authentication details and MFA satisfaction in sign-in logs. This is the relevant evidence check for this situation. MFA combines different factor categories to reduce account takeover from a stolen password alone.
Incorrect Answers
B:The workload accesses only the granted resource and no static application credential is embedded in code. This item belongs to a different control area: Managed identities. Its appropriate purpose is: Managed identities remove workload credential handling for supported Azure resources but still require appropriate authorization. For the stated case, Multifactor authentication is the closer match. MFA combines different factor categories to reduce account takeover from a stolen password alone.
C:Use Microsoft Entra ID as the cloud identity and access-management service for users, groups and applications. This item belongs to a different control area: Microsoft Entra ID cloud identity. Its appropriate purpose is: Microsoft Entra ID provides cloud directory and identity services, not network packet filtering or document retention. For the stated case, Multifactor authentication is the closer match. MFA combines different factor categories to reduce account takeover from a stolen password alone.
E:Inspect role definitions, active assignments and role audit events for tenant administrators. This item belongs to a different control area: Microsoft Entra role-based access control. Its appropriate purpose is: Entra administrative roles govern directory and identity operations; Azure resource RBAC is a separate scope model. For the stated case, Multifactor authentication is the closer match. MFA combines different factor categories to reduce account takeover from a stolen password alone.
