Microsoft SC-900 Practice Test 63

Question 620

Following a disaster recovery exercise at an international shipping company, the SOC lead has to defend a design against oversimplified assumptions. The requirement is: A data service should not be reachable from broad public network paths. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming foundational CSPM recommendations automatically enable every paid threat-protection plan.
  2. Assuming private networking removes the need to control which identities may read the data.
  3. Assuming each alert must be treated as an entirely independent breach without correlation.
  4. Assuming a hunting query returns events for devices that were never onboarded or supplied data.

Explanation

Correct Answer

B:

Assuming private networking removes the need to control which identities may read the data. This belief conflicts with this control principle: Network exposure reduction complements, rather than replaces, identity and application authorization. The appropriate response instead is: Design private or restricted service connectivity and enforce the intended subnet and network access controls.

Incorrect Answers

A:

Assuming foundational CSPM recommendations automatically enable every paid threat-protection plan. That caution concerns cloud workload protection; the specific misconception here is: Assuming private networking removes the need to control which identities may read the data.

C:

Assuming each alert must be treated as an entirely independent breach without correlation. That caution can be material to sentinel incident investigation, but it is not the specific flawed assumption described by this requirement. The relevant misconception is: Assuming private networking removes the need to control which identities may read the data.

D:

Assuming a hunting query returns events for devices that were never onboarded or supplied data. That caution concerns defender xdr advanced hunting; the specific misconception here is: Assuming private networking removes the need to control which identities may read the data.

Question 621

During an infrastructure modernization effort at a financial software company, the IT operations director records this concrete requirement: Two NSG rules appear to conflict for the same traffic, and an administrator needs to predict the result. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Use Microsoft Defender Vulnerability Management exposure and recommendation insights.
  2. Apply security orchestration, automation, and response workflows under appropriate control and approval.
  3. Use Microsoft Threat Intelligence capabilities to enrich relevant security analysis.
  4. Evaluate matching NSG rules in effective priority order and apply the intended first match.

Explanation

Correct Answer

D:

Evaluate matching NSG rules in effective priority order and apply the intended first match. This is the best match because NSG rule evaluation follows defined priority and direction, not a random last-created-rule order. A practical confirmation is: Inspect effective NSG rule priority and validate the predicted traffic outcome with connection tests.

Incorrect Answers

A:

Use Microsoft Defender Vulnerability Management exposure and recommendation insights. That addresses a different task: security needs a prioritized view of software exposure and remediation opportunities on devices. The present requirement concerns security rule priority.

B:

Apply security orchestration, automation, and response workflows under appropriate control and approval. This response addresses a different security or compliance task, namely: A SOC wants repeatable triage and response steps for commonly detected incidents. The immediate case instead calls for security rule priority; specifically, evaluate matching nsg rules in effective priority order and apply the intended first match.

C:

Use Microsoft Threat Intelligence capabilities to enrich relevant security analysis. This response addresses a different security or compliance task, namely: A threat analyst wants curated threat actor, infrastructure, and indicator context to inform an investigation. The immediate case instead calls for security rule priority; specifically, evaluate matching nsg rules in effective priority order and apply the intended first match.

Question 622

  3. Assuming the newest NSG rule always wins regardless of rule priority.
  4. Assuming one reported phishing email represents the entire campaign without searching related messages.

Explanation

Correct Answer

C:

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

A:

Assuming deploying a firewall alone verifies every container image and runtime configuration. That caution concerns defender for containers; the specific misconception here is: Assuming the newest NSG rule always wins regardless of rule priority.

B:

Assuming storage threat detections are equivalent to a corporate email phishing filter. That caution concerns defender for storage; the specific misconception here is: Assuming the newest NSG rule always wins regardless of rule priority.

D:

Assuming one reported phishing email represents the entire campaign without searching related messages. That caution concerns defender for office 365 investigation; the specific misconception here is: Assuming the newest NSG rule always wins regardless of rule priority.
