Microsoft SC-100 Practice Test 18

Question 170

A governance team has raised this design requirement: A pod runs as a privileged root container with host filesystem mounts for routine application logging. What should the cybersecurity architect recommend?

  1. Require trusted registry sources, image vulnerability checks and provenance verification.
  2. Apply least-privilege container runtime settings and eliminate unnecessary host access.
  3. Include image and dependency scanning for the exact release artifact.
  4. Add supported container runtime detection and managed-cluster threat protection.

Explanation

Correct Answer

B:

Privileged containers expand the impact of an application compromise to the host. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: Developers deploy container images directly from an unverified personal registry into production. Secure container supply chains need confidence in artifact origin and content. It does not solve the specified case, for which Apply least-privilege container runtime settings and eliminate unnecessary host access. is appropriate.

C:

This recommendation fits a different scenario: A team scans source code but never examines third-party packages shipped in the final container image. The deployed container can contain vulnerable components absent from source scans. It does not solve the specified case, for which Apply least-privilege container runtime settings and eliminate unnecessary host access. is appropriate.

D:

This recommendation fits a different scenario: Runtime detections are missing for workloads in a managed Kubernetes cluster despite completed image scanning. Build-time scanning does not observe malicious behavior after deployment. It does not solve the specified case, for which Apply least-privilege container runtime settings and eliminate unnecessary host access. is appropriate.

Question 171

A regulated organization needs a safer design because: A team moves a policy assignment into enforcement without testing its effect on existing resources. Which change MOST directly mitigates the design gap?

  1. Apply reviewed infrastructure-as-code changes and detect configuration drift against the declared baseline.
  2. Evaluate policy compliance and use a phased enforcement rollout with appropriate exemptions.
  3. Manage shared security templates through branch review and controlled pipeline promotion.
  4. Issue a time-bounded exception with justification, compensating safeguards and expiration review.

Explanation

Correct Answer

B:

Preventive policy can disrupt existing operations if not assessed first. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: Administrators make portal edits in production that drift from approved landing-zone templates. Reproducible templates make changes auditable and reduce hidden production variance. It does not solve the specified case, for which Evaluate policy compliance and use a phased enforcement rollout with appropriate exemptions. is appropriate.

C:

This recommendation fits a different scenario: Two teams edit shared network security definitions concurrently without versioned approval. Version control and peer approval reduce accidental changes to common network protections. It does not solve the specified case, for which Evaluate policy compliance and use a phased enforcement rollout with appropriate exemptions. is appropriate.

D:

This recommendation fits a different scenario: A workload owner requests a permanent exemption from encryption requirements for a short migration. Exceptions should not silently become enduring gaps in platform policy. It does not solve the specified case, for which Evaluate policy compliance and use a phased enforcement rollout with appropriate exemptions. is appropriate.

Question 172

A cybersecurity architect is evaluating the following business requirement: Existing resources violate a required diagnostic-settings policy, but the team assumes a policy assignment changes them retroactively. Which architecture recommendation BEST addresses the case?

  1. Require scoped Azure Policy exemptions with recorded rationale, owner and end date.
  2. Review initiative compliance at policy and resource levels and collect supporting configuration evidence.
  3. Use a scoped Azure Policy deny or equivalent enforcement effect for prohibited public storage configuration.
  4. Define remediation tasks and managed identities for supported deployIfNotExists policy effects.

Explanation

Correct Answer

D:

Assessment and remediation are different actions for already-deployed resources. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A production subscription receives a temporary security-policy exemption without business justification or expiry. Exceptions must remain reviewable, owned and time-bounded so temporary deviations do not become permanent exposures. It does not solve the specified case, for which Define remediation tasks and managed identities for supported deployIfNotExists policy effects. is appropriate.

B:

This recommendation fits a different scenario: A compliance team uses an initiative for common controls but cannot identify which resource failed each policy. Aggregated scores cannot replace specific failed-resource findings. It does not solve the specified case, for which Define remediation tasks and managed identities for supported deployIfNotExists policy effects. is appropriate.

C:

This recommendation fits a different scenario: Security standards require all new storage accounts to disable anonymous public blob access. Preventive guardrails stop noncompliant resources before they become exposed. It does not solve the specified case, for which Define remediation tasks and managed identities for supported deployIfNotExists policy effects. is appropriate.

Question 173

A hybrid-cloud design review identifies this security gap: A SQL team reviews vulnerability recommendations but has no way to investigate suspicious database queries. Which action is MOST appropriate for the stated need?

  1. Design Defender for Databases threat detection and database audit correlation.
  2. Correlate Defender storage detections with resource identity, workload owner and activity logs.
  3. Select Defender data workload plans based on actual protected services, licensing and risk.
  4. Evaluate Microsoft Defender for Storage protection and supported threat detections for the account.

Explanation

Correct Answer

A:

Data-plane attacks require investigation signals beyond posture findings. This choice directly fits the stated architecture requirement.

Incorrect Answers

B:

This recommendation fits a different scenario: A storage threat alert identifies a suspicious upload but the SOC cannot map it to a specific application owner. Alerting needs context to determine responsible systems and required containment. It does not solve the specified case, for which Design Defender for Databases threat detection and database audit correlation. is appropriate.

C:

This recommendation fits a different scenario: An architect enables all data threat protection plans without assessing resource coverage and ongoing ingestion cost. Protection choices should be justified by workload exposure and supported capabilities. It does not solve the specified case, for which Design Defender for Databases threat detection and database audit correlation. is appropriate.

D:

This recommendation fits a different scenario: A security architect turns on Defender for Cloud posture recommendations for storage but expects runtime alerts on malicious blob access automatically. Storage-specific threat protection is distinct from configuration assessment. It does not solve the specified case, for which Design Defender for Databases threat detection and database audit correlation. is appropriate.

Question 174

During a security architecture workshop, the team learns that: An automation deletes suspicious users immediately based only on a low-confidence anomaly signal. What should the cybersecurity architect recommend?

  1. Record playbook run IDs, incident links and action outcomes in the response evidence.
  2. Design a Logic Apps playbook triggered by validated Sentinel automation rules.
  3. Insert evidence checks, human approval and reversible containment before destructive SOAR actions.
  4. Design action-center review and approval responsibilities into the response workflow.

Explanation

Correct Answer

C:

Security automation must reflect confidence and potential business disruption. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A SOC cannot explain which playbook isolated a device after several overlapping detections. Automation needs traceability to support review, rollback and accountability. It does not solve the specified case, for which Insert evidence checks, human approval and reversible containment before destructive SOAR actions. is appropriate.

B:

This recommendation fits a different scenario: A Sentinel analytic rule produces hundreds of identical alerts, and analysts manually open tickets for each. SOAR automates repeatable steps while preserving scoped triggering and response authority. It does not solve the specified case, for which Insert evidence checks, human approval and reversible containment before destructive SOAR actions. is appropriate.

D:

This recommendation fits a different scenario: A Defender XDR automated investigation recommends an action that requires approval, but leadership assumes it already executed. Proposed automated response and executed remediation are distinct states. It does not solve the specified case, for which Insert evidence checks, human approval and reversible containment before destructive SOAR actions. is appropriate.

Question 175

A multinational enterprise reports this risk: An online store is targeted by repetitive automated login attempts, and the team only considers storage encryption. Which change MOST directly mitigates the design gap?

  1. Restrict origin access to trusted reverse proxies and protect the approved ingress path.
  2. Design bot, rate-limit and identity-abuse defenses in the application ingress architecture.
  3. Separate web, application and data tiers using controlled network segmentation.
  4. Enforce authenticated encryption on internal service-to-database traffic where supported.

Explanation

Correct Answer

B:

Credential stuffing is an application authentication threat rather than a data-at-rest issue. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A public API accepts traffic directly on its application origin even though the architecture diagram shows an edge firewall. A bypassable edge control cannot filter traffic that reaches the origin directly. It does not solve the specified case, for which Design bot, rate-limit and identity-abuse defenses in the application ingress architecture. is appropriate.

C:

This recommendation fits a different scenario: A multi-tier web app places its database and front end in the same unrestricted subnet. Tier isolation reduces lateral access to sensitive data components. It does not solve the specified case, for which Design bot, rate-limit and identity-abuse defenses in the application ingress architecture. is appropriate.

D:

This recommendation fits a different scenario: A web workload has public TLS but uses plaintext connections between its internal service and database. Internet TLS does not automatically secure backend service communications. It does not solve the specified case, for which Design bot, rate-limit and identity-abuse defenses in the application ingress architecture. is appropriate.

Question 176

An architecture approval board must resolve this concern: The AI governance board approves a model but no one owns evaluations for harmful outputs or data leakage. Which architecture recommendation BEST addresses the case?

  1. Define permitted training and fine-tuning data categories and privacy protections.
  2. Design scoped agent identities, approval gates and audited tool authorization.
  3. Perform AI data classification and access-path discovery before selecting the model architecture.
  4. Assign model risk ownership with preproduction safety, privacy and adversarial evaluation gates.

Explanation

Correct Answer

D:

Model approval needs measurable evidence and accountable remediation of observed safety failures. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A team sends every internal document to model tuning without confirming consent or data minimization rules. Data minimization and authorized provenance are security requirements throughout AI development. It does not solve the specified case, for which Assign model risk ownership with preproduction safety, privacy and adversarial evaluation gates. is appropriate.

B:

This recommendation fits a different scenario: An autonomous AI agent can call production administration tools with the operator's full credentials. An agent must not inherit unrestricted human powers merely because it is asked to automate tasks. It does not solve the specified case, for which Assign model risk ownership with preproduction safety, privacy and adversarial evaluation gates. is appropriate.

C:

This recommendation fits a different scenario: A company wants to deploy an AI assistant to answer HR questions but has not inventoried the sensitive data sources. Secure AI design starts with knowing which data the assistant may retrieve and expose. It does not solve the specified case, for which Assign model risk ownership with preproduction safety, privacy and adversarial evaluation gates. is appropriate.

Question 177

A security engineering lead describes the following problem: A phishing case is closed as resolved after mailbox cleanup although attacker-issued OAuth grants remain active. Which action is MOST appropriate for the stated need?

  1. Require confirmation of containment state and follow-up monitoring in incident playbooks.
  2. Add post-incident root-cause analysis and detection engineering follow-up to incident governance.
  3. Establish incident severity criteria, ownership and cross-team escalation procedures.
  4. Require persistence, identity and token remediation checks before incident closure.

Explanation

Correct Answer

D:

Removing an initial artifact does not establish that access mechanisms have been removed. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: Analysts isolate a server but no one validates whether that response action actually completed. Requested actions can remain pending or fail when devices are offline or disconnected. It does not solve the specified case, for which Require persistence, identity and token remediation checks before incident closure. is appropriate.

B:

This recommendation fits a different scenario: After a breach, investigators have no process to incorporate lessons into detection coverage. Repeated attack patterns persist if improvements are not linked to incidents. It does not solve the specified case, for which Require persistence, identity and token remediation checks before incident closure. is appropriate.

C:

This recommendation fits a different scenario: A critical incident is assigned to several teams without a named incident commander or escalation owner. A defined response lifecycle prevents conflicting containment and missed handoffs. It does not solve the specified case, for which Require persistence, identity and token remediation checks before incident closure. is appropriate.

Question 178

A governance team has raised this design requirement: An AI model accesses a document index containing unrelated departments' confidential files. What should the cybersecurity architect recommend?

  1. Apply data minimization, log access restrictions and approved retention for AI prompts and outputs.
  2. Require supported authentication and network restrictions for Azure AI service endpoints.
  3. Design user-aware retrieval security and filtered document access in the AI workload.
  4. Treat model input and retrieved text as untrusted, and gate privileged tool execution with policy.

Explanation

Correct Answer

C:

AI applications must respect original data entitlements during retrieval. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: An AI service sends model prompts into logs containing personal identifiers with indefinite retention. AI operational telemetry can itself contain sensitive regulated content. It does not solve the specified case, for which Design user-aware retrieval security and filtered document access in the AI workload. is appropriate.

B:

This recommendation fits a different scenario: An Azure AI service endpoint allows public anonymous queries because its output includes safety moderation. Content moderation does not authorize callers or prevent resource abuse. It does not solve the specified case, for which Design user-aware retrieval security and filtered document access in the AI workload. is appropriate.

D:

This recommendation fits a different scenario: A prompt-injection attack asks an AI assistant to run a privileged management API call. Untrusted instructions cannot supersede the application authorization boundary. It does not solve the specified case, for which Design user-aware retrieval security and filtered document access in the AI workload. is appropriate.

Question 179

A regulated organization needs a safer design because: A hospital has recovery objectives but has never quantified the maximum permissible data loss for patient scheduling. Which change MOST directly mitigates the design gap?

  1. Build a dependency map and test recovery of the identity, network and data services required by order processing.
  2. Rank cybersecurity recovery priorities using safety, outage impact and critical business processes rather than asset price alone.
  3. Perform a business impact analysis and map revenue-critical services to accountable owners and dependencies.
  4. Define a documented recovery point objective for the scheduling data and validate it against clinical risk.

Explanation

Correct Answer

D:

RPO specifies acceptable data loss and drives backup and replication design rather than merely restoration time. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A distribution firm promises one-hour recovery without identifying the network and identity systems its order platform needs. A recovered application is not usable if prerequisite identity and network control planes remain unavailable. It does not solve the specified case, for which Define a documented recovery point objective for the scheduling data and validate it against clinical risk. is appropriate.

B:

This recommendation fits a different scenario: Executives prioritize systems only by purchase cost, ignoring the operational harm of a manufacturing shutdown. Criticality reflects consequences for the mission and safety, not only the acquisition cost of hardware. It does not solve the specified case, for which Define a documented recovery point objective for the scheduling data and validate it against clinical risk. is appropriate.

C:

This recommendation fits a different scenario: A retailer cannot decide which workloads to restore first because all servers have equal priority labels. Business impact analysis distinguishes business-critical recovery order from an undifferentiated inventory of machines. It does not solve the specified case, for which Define a documented recovery point objective for the scheduling data and validate it against clinical risk. is appropriate.

Question 180

A cybersecurity architect is evaluating the following business requirement: A Secure Score rises after a control receives an exception status although the underlying user access configuration is unchanged. Which architecture recommendation BEST addresses the case?

  1. Rank Microsoft 365 hardening measures by exposure, business dependencies and tested rollout impact.
  2. Evaluate Microsoft Secure Score recommendations and effective protection for Microsoft 365 workloads.
  3. Distinguish Secure Score acceptance states from verified technical control enforcement.
  4. Normalize posture assessment for licensed controls, coverage and business-critical workloads.

Explanation

Correct Answer

C:

Assessment scores may not prove an unsafe configuration has been repaired. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: The security architect wants to prioritize tenant security improvements but cannot quantify the impact of disrupting daily collaboration. Security priorities should integrate risk reduction and operating continuity. It does not solve the specified case, for which Distinguish Secure Score acceptance states from verified technical control enforcement. is appropriate.

B:

This recommendation fits a different scenario: A collaboration tenant has several risky sharing settings but leadership only tracks purchased security licenses. Security product licensing does not establish that recommended controls are enabled. It does not solve the specified case, for which Distinguish Secure Score acceptance states from verified technical control enforcement. is appropriate.

D:

This recommendation fits a different scenario: An architect compares two Microsoft 365 tenants' security scores without considering their different licensed feature sets. Raw score comparison may be misleading when the set of eligible assessed controls differs. It does not solve the specified case, for which Distinguish Secure Score acceptance states from verified technical control enforcement. is appropriate.
