Microsoft SC-900 Practice Test 78

Question 770

During a migration readiness meeting at a healthcare cooperative, the application administrator 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. The team implements the following response: Use appropriate Azure DDoS Protection capabilities for public IP resources while planning application resiliency. Which evidence BEST verifies that the action met its stated purpose?

  1. Trigger a test alert and inspect the automated workflow run and resulting approved actions.
  2. Review protection coverage and attack telemetry or metrics for the protected public endpoint.
  3. Inspect investigation results, action approvals where configured, and remediation history.
  4. Run a hypothesis-driven hunt and record matching events or absence of evidence with scope.

Explanation

Correct Answer

B:

Review protection coverage and attack telemetry or metrics for the protected public endpoint. This tests the relevant control rather than an adjacent capability. The implemented response is: Use appropriate Azure DDoS Protection capabilities for public IP resources while planning application resiliency. The control principle is: DDoS Protection addresses denial-of-service traffic; it is not the same control as web-request inspection.

Incorrect Answers

A:

Trigger a test alert and inspect the automated workflow run and resulting approved actions. This would test soar concept, whereas the required evidence is: Review protection coverage and attack telemetry or metrics for the protected public endpoint.

C:

Inspect investigation results, action approvals where configured, and remediation history. This would test defender automated investigation, whereas the required evidence is: Review protection coverage and attack telemetry or metrics for the protected public endpoint.

D:

Run a hypothesis-driven hunt and record matching events or absence of evidence with scope. This would test sentinel threat hunting, whereas the required evidence is: Review protection coverage and attack telemetry or metrics for the protected public endpoint.

Question 771

Following an internal access audit at a public utility, the information governance lead has to defend a design against oversimplified assumptions. The requirement is: A public-facing Azure application requires mitigation against volumetric network-layer denial-of-service attacks. The review is limited to the control and concept described by this requirement. Which security, identity, or compliance principle MOST directly explains the appropriate approach?

  1. Threat intelligence adds adversary and indicator context that helps analysts prioritize and interpret signals.
  2. Defender for Storage is a workload-specific protection for storage resource threats.
  3. DDoS Protection addresses denial-of-service traffic; it is not the same control as web-request inspection.
  4. SOAR coordinates security processes and automates response actions; it complements detection.

Explanation

Correct Answer

C:

DDoS Protection addresses denial-of-service traffic; it is not the same control as web-request inspection. It explains why the selected measure—Use appropriate Azure DDoS Protection capabilities for public IP resources while planning application resiliency—fits the specific requirement. It should be verified by checking: Review protection coverage and attack telemetry or metrics for the protected public endpoint.

Incorrect Answers

A:

Threat intelligence adds adversary and indicator context that helps analysts prioritize and interpret signals. This describes microsoft threat intelligence; the governing concept here is: DDoS Protection addresses denial-of-service traffic; it is not the same control as web-request inspection.

B:

Defender for Storage is a workload-specific protection for storage resource threats. This describes defender for storage; the governing concept here is: DDoS Protection addresses denial-of-service traffic; it is not the same control as web-request inspection.

D:

SOAR coordinates security processes and automates response actions; it complements detection. This describes soar concept; the governing concept here is: DDoS Protection addresses denial-of-service traffic; it is not the same control as web-request inspection.

Question 772

Following an internal access audit at a public utility, the information governance lead has to defend a design against oversimplified assumptions. The requirement is: A public-facing Azure application requires mitigation against volumetric network-layer denial-of-service attacks. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming any unverified IP address list is equivalent to contextualized threat intelligence.
  2. Assuming enrolling a user in Entra alone deploys endpoint detection sensors to every laptop.
  3. Assuming Sentinel replaces all endpoint, email, and identity sensors that produce security signals.
  4. Assuming an HTTP WAF alone mitigates every network-layer flood against public IP infrastructure.

Explanation

Correct Answer

D:

Assuming an HTTP WAF alone mitigates every network-layer flood against public IP infrastructure. This belief conflicts with this control principle: DDoS Protection addresses denial-of-service traffic; it is not the same control as web-request inspection. The appropriate response instead is: Use appropriate Azure DDoS Protection capabilities for public IP resources while planning application resiliency.

Incorrect Answers

A:

Assuming any unverified IP address list is equivalent to contextualized threat intelligence. That caution concerns microsoft threat intelligence; the specific misconception here is: Assuming an HTTP WAF alone mitigates every network-layer flood against public IP infrastructure.

B:

Assuming enrolling a user in Entra alone deploys endpoint detection sensors to every laptop. That caution can be material to defender for endpoint, but it is not the specific flawed assumption described by this requirement. The relevant misconception is: Assuming an HTTP WAF alone mitigates every network-layer flood against public IP infrastructure.

C:

Assuming Sentinel replaces all endpoint, email, and identity sensors that produce security signals. That caution concerns microsoft sentinel central analytics; the specific misconception here is: Assuming an HTTP WAF alone mitigates every network-layer flood against public IP infrastructure.

Question 773

During an access-management redesign at a research institute, the incident responder records this concrete requirement: Multiple Azure subnets require centralized, stateful network traffic policy and logging. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Enable an appropriate Defender for Cloud workload protection plan for the relevant resource type.
  2. Use Azure Firewall and deliberate routing to enforce central network and application traffic rules.
  3. Use Microsoft Defender Vulnerability Management exposure and recommendation insights.
  4. Use supported Defender for Cloud Apps session controls integrated with the access policy.

Explanation

Correct Answer

B:

Use Azure Firewall and deliberate routing to enforce central network and application traffic rules. This is the best match because Azure Firewall supplies centralized network traffic inspection and rule enforcement for routed flows. A practical confirmation is: Inspect effective routes, matching firewall rules, and firewall diagnostic logs for sample connections.

Incorrect Answers

A:

Enable an appropriate Defender for Cloud workload protection plan for the relevant resource type. That addresses a different task: a deployed server needs threat alerts and workload-specific hardening rather than posture reporting alone. The present requirement concerns azure firewall.

C:

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 azure firewall.

D:

Use supported Defender for Cloud Apps session controls integrated with the access policy. This response addresses a different security or compliance task, namely: A company wants to restrict downloads from a risky cloud application session. The immediate case instead calls for azure firewall; specifically, use azure firewall and deliberate routing to enforce central network and application traffic rules.

Question 774

During an access-management redesign at a research institute, the incident responder records this concrete requirement: Multiple Azure subnets require centralized, stateful network traffic policy and logging. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Use Azure Firewall and deliberate routing to enforce central network and application traffic rules. Which evidence BEST verifies that the action met its stated purpose?

  1. Check recipient scope, malicious message verdicts, and remediation actions in the investigation.
  2. Inspect attachment verdicts and resulting delivery or quarantine actions on a controlled sample.
  3. Inspect effective routes, matching firewall rules, and firewall diagnostic logs for sample connections.
  4. Confirm sensor health and inspect alerts related to the supported directory environment.

Explanation

Correct Answer

C:

Inspect effective routes, matching firewall rules, and firewall diagnostic logs for sample connections. This tests the relevant control rather than an adjacent capability. The implemented response is: Use Azure Firewall and deliberate routing to enforce central network and application traffic rules. The control principle is: Azure Firewall supplies centralized network traffic inspection and rule enforcement for routed flows.

Incorrect Answers

A:

Check recipient scope, malicious message verdicts, and remediation actions in the investigation. This would test defender for office 365 investigation, whereas the required evidence is: Inspect effective routes, matching firewall rules, and firewall diagnostic logs for sample connections.

B:

Inspect attachment verdicts and resulting delivery or quarantine actions on a controlled sample. This would test safe attachments, whereas the required evidence is: Inspect effective routes, matching firewall rules, and firewall diagnostic logs for sample connections.

D:

Confirm sensor health and inspect alerts related to the supported directory environment. This would test defender for identity, whereas the required evidence is: Inspect effective routes, matching firewall rules, and firewall diagnostic logs for sample connections.

Question 775

Following a peer architecture review at a hospitality operator, the security architect has to defend a design against oversimplified assumptions. The requirement is: Multiple Azure subnets require centralized, stateful network traffic policy and logging. The review is limited to the control and concept described by this requirement. Which security, identity, or compliance principle MOST directly explains the appropriate approach?

  1. Incident management groups relevant security signals to support coordinated analysis.
  2. EDR is concerned with detecting and responding to endpoint behaviors after or during an attack.
  3. Secure score summarizes assessed posture improvements, not a certificate that attacks are impossible.
  4. Azure Firewall supplies centralized network traffic inspection and rule enforcement for routed flows.

Explanation

Correct Answer

D:

Azure Firewall supplies centralized network traffic inspection and rule enforcement for routed flows. It explains why the selected measure—Use Azure Firewall and deliberate routing to enforce central network and application traffic rules—fits the specific requirement. It should be verified by checking: Inspect effective routes, matching firewall rules, and firewall diagnostic logs for sample connections.

Incorrect Answers

A:

Incident management groups relevant security signals to support coordinated analysis. This describes sentinel incident investigation; the governing concept here is: Azure Firewall supplies centralized network traffic inspection and rule enforcement for routed flows.

B:

EDR is concerned with detecting and responding to endpoint behaviors after or during an attack. This describes endpoint detection and response; the governing concept here is: Azure Firewall supplies centralized network traffic inspection and rule enforcement for routed flows.

C:

Secure score summarizes assessed posture improvements, not a certificate that attacks are impossible. This describes defender for cloud secure score; the governing concept here is: Azure Firewall supplies centralized network traffic inspection and rule enforcement for routed flows.

Question 776

Following a peer architecture review at a hospitality operator, the security architect has to defend a design against oversimplified assumptions. The requirement is: Multiple Azure subnets require centralized, stateful network traffic policy and logging. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming Azure Firewall automatically inspects traffic that was never routed through it.
  2. Assuming a playbook with no trigger can respond to an incident as soon as one is ingested.
  3. Assuming an endpoint antivirus policy is an adequate substitute for email threat protections.
  4. Assuming an automated playbook always discovers threats without any alerting or trigger data.

Explanation

Correct Answer

A:

Assuming Azure Firewall automatically inspects traffic that was never routed through it. This belief conflicts with this control principle: Azure Firewall supplies centralized network traffic inspection and rule enforcement for routed flows. The appropriate response instead is: Use Azure Firewall and deliberate routing to enforce central network and application traffic rules.
