Microsoft SC-900 Practice Test 57

Question 560

Following a privileged access audit at a hospitality operator, the enterprise architect has to defend a design against oversimplified assumptions. The requirement is: An incident responder wants a central interface to triage supported Microsoft Defender alerts. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming Sentinel replaces all endpoint, email, and identity sensors that produce security signals.
  2. Assuming simply naming two subnets guarantees every unwanted flow is blocked without access rules.
  3. Assuming the Defender portal replaces Azure resource deployments, subscriptions, and identity RBAC configuration.
  4. Assuming the newest NSG rule always wins regardless of rule priority.

Explanation

Correct Answer

C:

Assuming the Defender portal replaces Azure resource deployments, subscriptions, and identity RBAC configuration. This belief conflicts with this control principle: The Defender portal unifies supported security operations experiences, not every Azure resource setting. The appropriate response instead is: Use the unified Microsoft Defender portal for supported incidents, alerts, and hunting workflows.

Incorrect Answers

A:

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 the Defender portal replaces Azure resource deployments, subscriptions, and identity RBAC configuration.

B:

Assuming simply naming two subnets guarantees every unwanted flow is blocked without access rules. That caution concerns azure virtual network segmentation; the specific misconception here is: Assuming the Defender portal replaces Azure resource deployments, subscriptions, and identity RBAC configuration.

D:

Assuming the newest NSG rule always wins regardless of rule priority. That caution concerns security rule priority; the specific misconception here is: Assuming the Defender portal replaces Azure resource deployments, subscriptions, and identity RBAC configuration.

Question 561

During a tenant consolidation at a regional insurer, the information governance lead records this concrete requirement: A SOC wants supported automated investigation and remediation for certain endpoint or email threats. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Use appropriate Defender automated investigation and response controls with reviewed permissions.
  2. Design private or restricted service connectivity and enforce the intended subnet and network access controls.
  3. Use an appropriate Defender for Servers protection plan and onboard the eligible machines.
  4. Use Microsoft Sentinel hunting queries against available telemetry and preserve findings.

Question 565

During a security controls rollout at a legal services firm, the security architect records this concrete requirement: A phishing email and an endpoint alert may represent one attack chain. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Use a Sentinel playbook and suitable trigger or automation configuration.
  2. Correlate related signals in Defender XDR rather than investigating the email and endpoint in silos.
  3. Enable an appropriate Defender for Cloud workload protection plan for the relevant resource type.
  4. Design private or restricted service connectivity and enforce the intended subnet and network access controls.

Explanation

Correct Answer

B:

Correlate related signals in Defender XDR rather than investigating the email and endpoint in silos. Cross-product correlation connects different attack stages through shared evidence. To verify, inspect common entities, incident timelines, and consolidated alert grouping.

Incorrect Answers

A:

Use a Sentinel playbook and suitable trigger or automation configuration. That addresses a different task: a SOC wants to automatically enrich an incident and notify an on-call team after detection. The present requirement concerns incident correlation across products.

C:

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 incident correlation across products.

D:

Design private or restricted service connectivity and enforce the intended subnet and network access controls. That addresses a different task: a data service should not be reachable from broad public network paths. The present requirement concerns incident correlation across products.
