Microsoft SC-900 Practice Test 61

Question 600

Following a licensing and controls review at a local government agency, the compliance analyst has to defend a design against oversimplified assumptions. The requirement is: Two application tiers need isolated address spaces and carefully controlled connectivity. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming simply naming two subnets guarantees every unwanted flow is blocked without access rules.
  2. Assuming an identity sign-in log contains every endpoint process tree and response action.
  3. Assuming an endpoint antivirus policy is an adequate substitute for email threat protections.
  4. Assuming posture assessments are identical to real-time interception of every malicious packet.

Explanation

Correct Answer

A:

Assuming simply naming two subnets guarantees every unwanted flow is blocked without access rules. This belief conflicts with this control principle: Network segmentation creates logical boundaries that other network controls can enforce. The appropriate response instead is: Separate network components with Azure virtual networks or subnets and explicit connectivity design.

Incorrect Answers

B:

Assuming an identity sign-in log contains every endpoint process tree and response action. That caution concerns endpoint detection and response; the specific misconception here is: Assuming simply naming two subnets guarantees every unwanted flow is blocked without access rules.

C:

Assuming an endpoint antivirus policy is an adequate substitute for email threat protections. That caution concerns defender for office 365; the specific misconception here is: Assuming simply naming two subnets guarantees every unwanted flow is blocked without access rules.

D:

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 simply naming two subnets guarantees every unwanted flow is blocked without access rules.

Question 601

During a security controls rollout at a construction engineering group, the SOC lead records this concrete requirement: A subnet must permit application traffic on one port while denying unwanted inbound flows. 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. Use Defender for Cloud regulatory compliance views with appropriate configured standards.
  3. Apply appropriately scoped network security group rules to the subnet or network interface.
  4. Use Defender XDR advanced hunting queries over available supported data.

Explanation

Correct Answer

C:

Apply appropriately scoped network security group rules to the subnet or network interface. This is the best match because NSGs evaluate allow or deny rules for network traffic at subnet or interface scope. A practical confirmation is: Check effective security rules and validate allowed and denied connectivity to the target port.

Incorrect Answers

A:

Apply security orchestration, automation, and response workflows under appropriate control and approval. That addresses a different task: a SOC wants repeatable triage and response steps for commonly detected incidents. The present requirement concerns network security groups.

B:

Use Defender for Cloud regulatory compliance views with appropriate configured standards. That addresses a different task: an auditor wants to map cloud resource assessments to selected regulatory standards. The present requirement concerns network security groups.

D:

Use Defender XDR advanced hunting queries over available supported data. That addresses a different task: analysts need to search supported security telemetry for a new attack technique across endpoints. The present requirement concerns network security groups.

Question 602

During a security controls rollout at a construction engineering group, the SOC lead records this concrete requirement: A subnet must permit application traffic on one port while denying unwanted inbound flows. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Apply appropriately scoped network security group rules to the subnet or network interface. Which evidence BEST verifies that the action met its stated purpose?

  1. Inspect ingested events, matching analytics rules, and the resulting Sentinel incident.
  2. Inspect application permissions, detected app activity, and revocation or remediation decisions.
  3. Trigger a test alert and inspect the automated workflow run and resulting approved actions.
  4. Check effective security rules and validate allowed and denied connectivity to the target port.

Explanation

Correct Answer

D:

Check effective security rules and validate allowed and denied connectivity to the target port. This tests the relevant control rather than an adjacent capability. The implemented response is: Apply appropriately scoped network security group rules to the subnet or network interface. The control principle is: NSGs evaluate allow or deny rules for network traffic at subnet or interface scope.

Incorrect Answers
