Microsoft SC-100 Practice Test 27

Question 260

A security engineering lead describes the following problem: A software vendor claims SOC reports prove that every custom configuration of its application is secure. Which action is MOST appropriate for the stated need?

  1. Prioritize application posture findings by reachable attack paths and regulated data impact.
  2. Validate the application-specific configuration and customer responsibility model separately from vendor assurances.
  3. Assign application security ownership and a funded vulnerability management lifecycle.
  4. Build an application security inventory with criticality, exposure, ownership and identity dependencies.

Explanation

Correct Answer

B:

General vendor audits do not verify the purchaser's unique deployment controls. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: An application assessment scores a public healthcare API and an internal demo app equally because both lack one HTTP header. Contextual risk matters more than equal treatment of every checklist failure. It does not solve the specified case, for which Validate the application-specific configuration and customer responsibility model separately from vendor assurances. is appropriate.

C:

This recommendation fits a different scenario: A security board authorizes a new application but no one owns future dependency updates. Application protection must continue after initial launch and approval. It does not solve the specified case, for which Validate the application-specific configuration and customer responsibility model separately from vendor assurances. is appropriate.

D:

This recommendation fits a different scenario: A corporation has hundreds of internal apps but no inventory of their hosting, owners or authentication methods. Portfolio risk cannot be assessed without knowing the applications and their attack surfaces. It does not solve the specified case, for which Validate the application-specific configuration and customer responsibility model separately from vendor assurances. is appropriate.

Question 261

A governance team has raised this design requirement: A PaaS application team disables authentication because the underlying service platform already uses encryption. What should the cybersecurity architect recommend?

  1. Define customer-owned SaaS identity, sharing and data-protection configuration requirements.
  2. Allocate customer responsibility for guest OS and application security under the IaaS service model.
  3. Require application identity, authorization and secret controls for PaaS workloads.
  4. Create service-model-specific control profiles anchored in shared enterprise security requirements.

Explanation

Correct Answer

C:

Provider platform safeguards do not authenticate application users or authorize data access. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A workload team assumes a SaaS provider automatically controls which internal employees can export confidential files. SaaS providers operate the service but customer access settings remain a shared-responsibility concern. It does not solve the specified case, for which Require application identity, authorization and secret controls for PaaS workloads. is appropriate.

B:

This recommendation fits a different scenario: An Azure VM owner assumes Microsoft patches every custom application installed inside the guest. IaaS customers remain responsible for many workload and software controls. It does not solve the specified case, for which Require application identity, authorization and secret controls for PaaS workloads. is appropriate.

D:

This recommendation fits a different scenario: The same baseline is applied without adaptation to Kubernetes nodes, managed SQL and Microsoft 365. IaaS, PaaS and SaaS expose different customer-configurable control surfaces. It does not solve the specified case, for which Require application identity, authorization and secret controls for PaaS workloads. is appropriate.

Question 262

A regulated organization needs a safer design because: A vendor requests unrestricted production database access to provide temporary support. Which change MOST directly mitigates the design gap?

  1. Include credential revocation and third-party access closure in the data decommissioning plan.
  2. Conduct third-party data-processing due diligence and define contractual security obligations.
  3. Evaluate cross-border data movement restrictions and design approved transfer controls before exporting.
  4. Approve time-limited narrowly scoped vendor access with monitored sessions and expiry.

Explanation

Correct Answer

D:

Contracted support does not justify enduring broad access to regulated records. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A project retires a cloud application but leaves external vendors with active keys to its archived data. Retired workloads can retain accessible sensitive data if external grants persist. It does not solve the specified case, for which Approve time-limited narrowly scoped vendor access with monitored sessions and expiry. is appropriate.

B:

This recommendation fits a different scenario: A SaaS supplier will process regulated customer data but the security team has not assessed its subcontractors. Supply-chain privacy duties extend beyond the immediate service provider. It does not solve the specified case, for which Approve time-limited narrowly scoped vendor access with monitored sessions and expiry. is appropriate.

C:

This recommendation fits a different scenario: A database export crosses a legal jurisdiction without a documented business purpose or residency assessment. Data transfers may trigger obligations that network encryption alone cannot satisfy. It does not solve the specified case, for which Approve time-limited narrowly scoped vendor access with monitored sessions and expiry. is appropriate.

Question 263

A cybersecurity architect is evaluating the following business requirement: A chatbot sends sensitive prompts to a third-party service without documenting retention or residency terms. Which architecture recommendation BEST addresses the case?

  1. Restrict retrieval to user-authorized content and enforce data-plane access controls in the AI pipeline.
  2. Include prompt-injection threat modeling and policy-enforced tool and data boundaries around the model.
  3. Establish AI data-handling requirements for storage, processing locations and vendor agreements before approval.
  4. Enforce model endpoint authentication, authorization and logging independently of content safety controls.

Explanation

Correct Answer

C:

Secure AI adoption includes privacy and contractual data processing controls, not only model accuracy. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A generative AI application can read unrelated customer records through its retrieval index. Retrieval-augmented generation must not bypass original source authorization. It does not solve the specified case, for which Establish AI data-handling requirements for storage, processing locations and vendor agreements before approval. is appropriate.

B:

This recommendation fits a different scenario: A model deployment accepts unfiltered user prompts that may cause the assistant to reveal privileged system instructions. Untrusted prompts must not be treated as authority to use privileged tools or disclose protected context. It does not solve the specified case, for which Establish AI data-handling requirements for storage, processing locations and vendor agreements before approval. is appropriate.

D:

This recommendation fits a different scenario: An AI team enables broad model endpoint access because it assumes safety filters also restrict callers. Content filtering evaluates outputs but does not substitute for access control to model resources. It does not solve the specified case, for which Establish AI data-handling requirements for storage, processing locations and vendor agreements before approval. is appropriate.

Question 264

A hybrid-cloud design review identifies this security gap: A security program wants to track whether strategic exposure-reduction initiatives improve over several months. Which action is MOST appropriate for the stated need?

  1. Coordinate remediation priorities across endpoint and identity owners using attack-path analysis.
  2. Use Security Exposure Management attack paths and asset criticality to prioritize the chained risk.
  3. Distinguish modeled exposure relationships from confirmed compromise telemetry and incident evidence.
  4. Design a measurable exposure-management initiative review with consistent scope and trend baselines.

Explanation

Correct Answer

D:

Trend assessment requires stable coverage and explicit outcomes, not only one dashboard snapshot. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: Two teams independently patch the same low-impact issue while a high-risk identity-to-server path remains open. Cross-domain attack paths require joint mitigation rather than isolated asset queues. It does not solve the specified case, for which Design a measurable exposure-management initiative review with consistent scope and trend baselines. is appropriate.

B:

This recommendation fits a different scenario: A vulnerable workstation links to a privileged service account, but teams prioritize only by its standalone CVSS number. Reachability to privileged resources can matter more than a single isolated severity label. It does not solve the specified case, for which Design a measurable exposure-management initiative review with consistent scope and trend baselines. is appropriate.

C:

This recommendation fits a different scenario: The exposure team treats every modeled attack path as evidence that an adversary has already traversed it. Risk graph edges show possible paths, not proof of actual execution. It does not solve the specified case, for which Design a measurable exposure-management initiative review with consistent scope and trend baselines. is appropriate.

Question 265

During a security architecture workshop, the team learns that: A former contractor remains eligible for Global Administrator role activation months after their project ends. What should the cybersecurity architect recommend?

  1. Use Entra Privileged Identity Management eligible assignments with time-bounded activation.
  2. Configure approval and justification in the applicable PIM activation policy.
  3. Review PIM eligibility periodically and revoke assignments without current business sponsorship.
  4. Use PIM activation and directory audit history to reconstruct the elevation timeline.

Explanation

Correct Answer

C:

Eligible assignments are still an access risk even when not activated. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A security engineer needs elevated directory permissions for one maintenance window but currently holds them permanently. Just-in-time privilege limits the duration of sensitive access while retaining a verifiable activation record. It does not solve the specified case, for which Review PIM eligibility periodically and revoke assignments without current business sponsorship. is appropriate.

B:

This recommendation fits a different scenario: A privileged role activation proceeds without approval even though high-impact changes require a second person. Privilege elevation can be gated on accountable independent authorization. It does not solve the specified case, for which Review PIM eligibility periodically and revoke assignments without current business sponsorship. is appropriate.

D:

This recommendation fits a different scenario: The SOC cannot identify who activated a privileged role just before suspicious tenant configuration changes. Traceable activation events connect privileged authority to specific actions and dates. It does not solve the specified case, for which Review PIM eligibility periodically and revoke assignments without current business sponsorship. is appropriate.

Question 266

A multinational enterprise reports this risk: A model training job copies regulated customer records into a globally shared temporary storage account. Which change MOST directly mitigates the design gap?

  1. Apply data minimization, restricted processing locations and controlled storage to training datasets.
  2. Limit AI prompt telemetry, mask sensitive fields and enforce approved retention and audit permissions.
  3. Enforce user-context data authorization before returning retrieved passages to the model.
  4. Design prompt-injection defenses with explicit tool permission and output-data boundaries.

Explanation

Correct Answer

A:

AI development pipelines require the same confidentiality and residency safeguards as production systems. This choice directly fits the stated architecture requirement.

Incorrect Answers

B:

This recommendation fits a different scenario: A generative AI team logs raw confidential prompts for debugging but cannot define who is permitted to access them. Generated and submitted content can contain regulated information needing protective handling. It does not solve the specified case, for which Apply data minimization, restricted processing locations and controlled storage to training datasets. is appropriate.

C:

This recommendation fits a different scenario: A retrieval AI assistant indexes confidential board documents for all employees without honoring SharePoint permissions. AI retrieval must not elevate the caller's rights to indexed content. It does not solve the specified case, for which Apply data minimization, restricted processing locations and controlled storage to training datasets. is appropriate.

D:

This recommendation fits a different scenario: A prompt contains untrusted instructions telling a tool-using model to disclose the full hidden customer dataset. Model instruction filters cannot replace independent enforcement on protected data tools. It does not solve the specified case, for which Apply data minimization, restricted processing locations and controlled storage to training datasets. is appropriate.

Question 267

An architecture approval board must resolve this concern: An externally accessible test API contains a stale authentication endpoint, but no business owner is listed. Which architecture recommendation BEST addresses the case?

  1. Validate attribution and ownership before treating discovered infrastructure as an enterprise asset.
  2. Link discovered internet-facing assets to application owners and prioritize exposed authentication surfaces.
  3. Reconcile EASM findings with decommissioning and verify public DNS and hosting retirement.
  4. Use Defender External Attack Surface Management discovery to inventory internet-visible assets.

Explanation

Correct Answer

B:

Unknown ownership delays remediation of publicly reachable sensitive interfaces. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: An exposure report shows an unknown domain and administrators assume the organization owns it. Discovery signals require evidence before responsibility or remediation is assigned. It does not solve the specified case, for which Link discovered internet-facing assets to application owners and prioritize exposed authentication surfaces. is appropriate.

C:

This recommendation fits a different scenario: A business removes a legacy service but external scanners still find the previous endpoint. Internet-facing exposure can persist after internal retirement records say a service is gone. It does not solve the specified case, for which Link discovered internet-facing assets to application owners and prioritize exposed authentication surfaces. is appropriate.

D:

This recommendation fits a different scenario: The security team knows internal IP addresses but not the public domains and hosts registered by acquired subsidiaries. External discovery reveals assets beyond known internal CMDB entries. It does not solve the specified case, for which Link discovered internet-facing assets to application owners and prioritize exposed authentication surfaces. is appropriate.

Question 268

A security engineering lead describes the following problem: A Linux estate appears Arc-connected but security extensions are missing on half the servers. Which action is MOST appropriate for the stated need?

  1. Use a controlled onboarding identity and rotate bootstrap credentials with least-privilege permissions.
  2. Validate desired extension deployment and policy compliance across Arc-enabled resource groups.
  3. Confirm feature support and shared operational responsibilities for Arc-enabled non-Azure servers.
  4. Connect eligible non-Azure machines using Azure Arc-enabled servers and approved onboarding methods.

Explanation

Correct Answer

B:

Registration alone does not prove that each required protection component is installed. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: An Arc deployment script embeds a long-lived tenant secret with unrestricted resource creation rights. Hybrid management agents must not create an uncontrolled credential exposure path. It does not solve the specified case, for which Validate desired extension deployment and policy compliance across Arc-enabled resource groups. is appropriate.

C:

This recommendation fits a different scenario: An application team assumes Arc-enabled machines automatically become full Azure virtual machines for every control. Azure Arc extends selected management capabilities without replacing the original hosting environment. It does not solve the specified case, for which Validate desired extension deployment and policy compliance across Arc-enabled resource groups. is appropriate.

D:

This recommendation fits a different scenario: On-premises Linux servers are excluded from Azure inventory and policy compliance checks. Azure Arc can expose supported external machines to Azure governance and security integrations. It does not solve the specified case, for which Validate desired extension deployment and policy compliance across Arc-enabled resource groups. is appropriate.

Question 269

A governance team has raised this design requirement: A regional team wants to deploy controls without identifying the owner responsible for operating them. What should the cybersecurity architect recommend?

  1. Design defense in depth with distinct controls across identities, devices, applications, network and data.
  2. Assign control owners, measurable assurance evidence and escalation paths for each architecture capability.
  3. Extend trust-boundary diagrams to cover both organizations and their cross-tenant connections.
  4. Map security requirements to Microsoft Cybersecurity Reference Architectures capabilities before selecting products.

Explanation

Correct Answer

B:

Control ownership makes an architectural recommendation maintainable and auditable after rollout. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A program proposes one global firewall as a substitute for application, identity and data security controls. No single perimeter control replaces workload-specific authorization and protection. It does not solve the specified case, for which Assign control owners, measurable assurance evidence and escalation paths for each architecture capability. is appropriate.

C:

This recommendation fits a different scenario: A merger introduces a new cloud estate but the reference architecture has not mapped its administrative trust boundaries. Security architecture must represent newly introduced identity boundaries and lateral-movement paths. It does not solve the specified case, for which Assign control owners, measurable assurance evidence and escalation paths for each architecture capability. is appropriate.

D:

This recommendation fits a different scenario: An enterprise compares two security tool purchases without first defining which identity, network and data threats must be covered. Capability mapping exposes gaps and dependencies independently of product branding. It does not solve the specified case, for which Assign control owners, measurable assurance evidence and escalation paths for each architecture capability. is appropriate.

Question 270

A regulated organization needs a safer design because: A team scans source code but never examines third-party packages shipped in the final container image. Which change MOST directly mitigates the design gap?

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

Explanation

Correct Answer

B:

The deployed container can contain vulnerable components absent from source scans. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A pod runs as a privileged root container with host filesystem mounts for routine application logging. Privileged containers expand the impact of an application compromise to the host. It does not solve the specified case, for which Include image and dependency scanning for the exact release artifact. is appropriate.

C:

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 Include image and dependency scanning for the exact release artifact. is appropriate.

D:

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 Include image and dependency scanning for the exact release artifact. is appropriate.
