Question 400
Following an external assurance discussion at a retail payments business, the incident responder has to defend a design against oversimplified assumptions. The requirement is: An internal employee needs an account governed by the organization's identity tenant. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?
- Assuming a directory user profile alone explains each failed sign-in and applied policy decision.
- Assuming a policy in report-only mode is already enforcing its grant requirements.
- Treating an internal employee's user account as the same object type as an application service principal.
- Assuming access approved once during onboarding never needs re-evaluation.
Explanation
Correct Answer
C:Treating an internal employee's user account as the same object type as an application service principal. This belief conflicts with this control principle: Member identities typically represent internal tenant users with organizational lifecycle governance. The appropriate response instead is: Create or provision a member user identity and assign appropriate access through directory groups or roles.
Incorrect Answers
A:Assuming a directory user profile alone explains each failed sign-in and applied policy decision. That caution concerns sign-in logs; the specific misconception here is: Treating an internal employee's user account as the same object type as an application service principal.
B:Assuming a policy in report-only mode is already enforcing its grant requirements. That caution can be material to conditional access mfa requirement, but it is not the specific flawed assumption described by this requirement. The relevant misconception is: Treating an internal employee's user account as the same object type as an application service principal.
D:Assuming access approved once during onboarding never needs re-evaluation. That caution concerns access reviews; the specific misconception here is: Treating an internal employee's user account as the same object type as an application service principal.
