Question 700

Following a quarterly control assessment at a healthcare cooperative, the technology auditor has to defend a design against oversimplified assumptions. The requirement is: A SOC must correlate identity, endpoint, email, and cloud application security incidents. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming private networking removes the need to control which identities may read the data.
  2. Assuming Defender XDR is only a single antivirus engine and cannot correlate supported security domains.
  3. Assuming a plain environment variable checked into source control provides equivalent secret governance.
  4. Assuming every virtual machine must expose TCP 3389 or 22 publicly for remote administration.

Explanation

Correct Answer

B:

Assuming Defender XDR is only a single antivirus engine and cannot correlate supported security domains. This belief conflicts with this control principle: Defender XDR connects supported Microsoft threat-protection signals for unified investigation and response. The appropriate response instead is: Use Microsoft Defender XDR's unified incident and cross-domain investigation experience.

Incorrect Answers

A:

Assuming private networking removes the need to control which identities may read the data. That caution concerns private connectivity and subnet rules; the specific misconception here is: Assuming Defender XDR is only a single antivirus engine and cannot correlate supported security domains.

C:

Assuming a plain environment variable checked into source control provides equivalent secret governance. That caution concerns azure key vault; the specific misconception here is: Assuming Defender XDR is only a single antivirus engine and cannot correlate supported security domains.

D:

Assuming every virtual machine must expose TCP 3389 or 22 publicly for remote administration. That caution concerns azure bastion; the specific misconception here is: Assuming Defender XDR is only a single antivirus engine and cannot correlate supported security domains.

Question 701

During a baseline configuration review at an investment advisory office, the application administrator records this concrete requirement: A mail security team needs protection and investigation for malicious messages and phishing. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Apply security orchestration, automation, and response workflows under appropriate control and approval.
  2. Assign appropriate security policies or standards and use assessed results to guide corrections.
  3. Use Microsoft Sentinel analytics and incident capabilities across connected data.
  4. Use Microsoft Defender for Office 365 for supported email and collaboration threat protection.

Explanation

Correct Answer

D:

Use Microsoft Defender for Office 365 for supported email and collaboration threat protection.
