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?

  1. Assuming a directory user profile alone explains each failed sign-in and applied policy decision.
  2. Assuming a policy in report-only mode is already enforcing its grant requirements.
  3. Treating an internal employee's user account as the same object type as an application service principal.
  4. 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.

Question 401

During an operational risk workshop at a regional insurer, the compliance analyst records this concrete requirement: A public-facing Azure application requires mitigation against volumetric network-layer denial-of-service attacks. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Use appropriate Azure DDoS Protection capabilities for public IP resources while planning application resiliency.
  2. Use Microsoft Defender for Office 365 for supported email and collaboration threat protection.
  3. Use Microsoft Defender for Cloud Apps discovery and cloud app monitoring capabilities.
  4. Use supported Defender for Cloud Apps session controls integrated with the access policy.

Explanation
