Microsoft SC-900 Practice Test 45

Question 440

Following a compliance walkthrough at a regional insurer, the SOC lead has to defend a design against oversimplified assumptions. The requirement is: Two NSG rules appear to conflict for the same traffic, and an administrator needs to predict the result. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming the newest NSG rule always wins regardless of rule priority.
  2. Assuming each alert must be treated as an entirely independent breach without correlation.
  3. Assuming posture assessments are identical to real-time interception of every malicious packet.
  4. Assuming endpoint antivirus signatures prove every installed application is fully patched.

Explanation

Correct Answer

A:

Assuming the newest NSG rule always wins regardless of rule priority. This belief conflicts with this control principle: NSG rule evaluation follows defined priority and direction, not a random last-created-rule order. The appropriate response instead is: Evaluate matching NSG rules in effective priority order and apply the intended first match.

Incorrect Answers

B:

Assuming each alert must be treated as an entirely independent breach without correlation. That caution concerns sentinel incident investigation; the specific misconception here is: Assuming the newest NSG rule always wins regardless of rule priority.

C:

Assuming posture assessments are identical to real-time interception of every malicious packet. That caution concerns cloud security posture management; the specific misconception here is: Assuming the newest NSG rule always wins regardless of rule priority.

D:

Assuming endpoint antivirus signatures prove every installed application is fully patched. That caution concerns defender vulnerability management; the specific misconception here is: Assuming the newest NSG rule always wins regardless of rule priority.
