Microsoft SC-100 Practice Test 14

Question 130

A governance team has raised this design requirement: An API gateway accepts unlimited requests from every subscription and the backend repeatedly exhausts capacity. What should the cybersecurity architect recommend?

  1. Design governed API versioning and staged deprecation for breaking changes.
  2. Redact credentials and personal content in API telemetry and restrict diagnostic access.
  3. Design authenticated partner identities and per-API authorization in Azure API Management.
  4. Configure appropriate API Management rate and quota limits aligned to business contracts.

Explanation

Correct Answer

D:

Traffic governance protects availability and enforces fair resource consumption. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: An architect publishes an API without a revision or version policy, breaking all consumers when its contract changes. Explicit version lifecycle protects dependent applications during interface evolution. It does not solve the specified case, for which Configure appropriate API Management rate and quota limits aligned to business contracts. is appropriate.

B:

This recommendation fits a different scenario: A gateway logs full bearer tokens and sensitive request payloads to an unrestricted workspace. Observability should not leak the secrets and data it is intended to protect. It does not solve the specified case, for which Configure appropriate API Management rate and quota limits aligned to business contracts. is appropriate.

C:

This recommendation fits a different scenario: A partner API receives legitimate requests but cannot distinguish which partner is allowed to call a sensitive operation. Gateway policies can enforce caller-specific API access rather than only route traffic. It does not solve the specified case, for which Configure appropriate API Management rate and quota limits aligned to business contracts. is appropriate.

Question 131

A regulated organization needs a safer design because: An Azure-hosted application uses a shared storage account key although it runs on managed compute. Which change MOST directly mitigates the design gap?

  1. Federate the SaaS application with Microsoft Entra ID and govern access through supported assignments.
  2. Prefer a managed identity with Azure RBAC for supported service-to-service access.
  3. Grant the monitoring principal a suitable scoped read role rather than subscription-wide ownership.
  4. Assess the application's supported authentication bridge and enforce suitable compensating access controls.

Explanation

Correct Answer

B:

Managed identities avoid long-lived application secrets and permit scoped authorization. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A SaaS vendor offers SAML sign-in but employees keep separate unmanaged passwords for the service. Central identity reduces unmanaged credential stores and supports consistent access lifecycle. It does not solve the specified case, for which Prefer a managed identity with Azure RBAC for supported service-to-service access. is appropriate.

C:

This recommendation fits a different scenario: An IaaS administrator assigns subscription Owner to a monitoring agent that only needs to read diagnostics. Service identities should have permissions aligned to their actual operations. It does not solve the specified case, for which Prefer a managed identity with Azure RBAC for supported service-to-service access. is appropriate.

D:

This recommendation fits a different scenario: A legacy on-premises application cannot use modern federation, but a cloud access design assumes SSO alone resolves the constraint. Legacy protocols need their own migration and protection approach rather than assumed compatibility. It does not solve the specified case, for which Prefer a managed identity with Azure RBAC for supported service-to-service access. is appropriate.

Question 132

A cybersecurity architect is evaluating the following business requirement: A Zero Trust roadmap lists technologies but never defines the current maturity of the identity and device estate. Which architecture recommendation BEST addresses the case?

  1. Plan a risk-based migration with tested access policies and documented legacy exceptions.
  2. Design explicit verification of identity, device state and resource authorization for every sensitive access path.
  3. Assess maturity by pillar and sequence improvements with owners, milestones and measurable outcomes.
  4. Extend Zero Trust governance to workload identities and evaluate their exact resource scopes.

Explanation

Correct Answer

C:

Adoption is a staged capability program rather than a single product installation. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A security team proposes blocking every legacy application immediately despite no inventory of affected business functions. Zero Trust transformation needs controlled transition rather than unplanned production lockouts. It does not solve the specified case, for which Assess maturity by pillar and sequence improvements with owners, milestones and measurable outcomes. is appropriate.

B:

This recommendation fits a different scenario: The organization equates network location inside its headquarters with unrestricted trust. Zero Trust does not assume a trusted user solely from an internal IP address. It does not solve the specified case, for which Assess maturity by pillar and sequence improvements with owners, milestones and measurable outcomes. is appropriate.

D:

This recommendation fits a different scenario: A company implements least privilege for users but gives unattended integration accounts indefinite broad permissions. Nonhuman identities are principals that can bypass human-focused access reviews if ignored. It does not solve the specified case, for which Assess maturity by pillar and sequence improvements with owners, milestones and measurable outcomes. is appropriate.

Question 133

A hybrid-cloud design review identifies this security gap: An enterprise collects custom firewall and application logs from several clouds that lack native XDR incident correlation. Which action is MOST appropriate for the stated need?

  1. Design Microsoft Sentinel SIEM ingestion with normalized sources and analytic detection rules.
  2. Plan the supported Defender portal and Sentinel integration model with clear incident ownership.
  3. Select high-value event sources and retention tiers from detection use cases and ingestion budgets.
  4. Design Microsoft Defender XDR incident correlation for supported cross-workload detections.

Explanation

Correct Answer

A:

A SIEM provides flexible collection and analytics across disparate telemetry sources. This choice directly fits the stated architecture requirement.

Incorrect Answers

B:

This recommendation fits a different scenario: An architect wants Defender XDR incidents and Sentinel investigations to share context without treating them as two competing systems. Integration choices should preserve a consistent case workflow rather than create duplicate response queues. It does not solve the specified case, for which Design Microsoft Sentinel SIEM ingestion with normalized sources and analytic detection rules. is appropriate.

C:

This recommendation fits a different scenario: A threat detection program buys SIEM capacity without deciding which signals are needed or their retention costs. Detection-driven collection balances forensic coverage with sustainable telemetry costs. It does not solve the specified case, for which Design Microsoft Sentinel SIEM ingestion with normalized sources and analytic detection rules. is appropriate.

D:

This recommendation fits a different scenario: A global SOC monitors endpoint, identity and email attacks but cannot correlate them into a single investigation. XDR groups related endpoint, identity and email evidence into coherent attack investigations. It does not solve the specified case, for which Design Microsoft Sentinel SIEM ingestion with normalized sources and analytic detection rules. is appropriate.

Question 134

During a security architecture workshop, the team learns that: A company registers agent identities but has no lifecycle owner or process for revoking their access after retirement. What should the cybersecurity architect recommend?

  1. Validate supported Agent ID capabilities and Conditional Access applicability before committing to the architecture.
  2. Design a distinct governed agent identity with only the API privileges required by the task.
  3. Establish agent identity inventory, ownership, review and deprovisioning controls.
  4. Require policy checks and explicit approval for sensitive agent tool actions.

Explanation

Correct Answer

C:

Nonhuman principals can retain persistent access after the associated workflow stops. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A cross-tenant agent integration is proposed without verifying the current Microsoft Entra Agent ID feature and licensing support. Preview and GA boundaries can affect which agent access controls are available in a given tenant. It does not solve the specified case, for which Establish agent identity inventory, ownership, review and deprovisioning controls. is appropriate.

B:

This recommendation fits a different scenario: An autonomous assistant needs to call an internal ticket API without inheriting its developer's personal Global Administrator token. Agent authorization should be separable from the human user's broad administrative roles. It does not solve the specified case, for which Establish agent identity inventory, ownership, review and deprovisioning controls. is appropriate.

D:

This recommendation fits a different scenario: An AI agent can invoke a high-impact resource deletion tool based on text copied from an untrusted document. Untrusted content must not become authority to perform privileged destructive operations. It does not solve the specified case, for which Establish agent identity inventory, ownership, review and deprovisioning controls. is appropriate.

Question 135

A multinational enterprise reports this risk: An analyst exports large quantities of customer data to personal cloud storage without triggering monitoring. Which change MOST directly mitigates the design gap?

  1. Design data exfiltration monitoring and destination restrictions based on data classification.
  2. Establish data incident triage that confirms identities, accessed records and containment scope.
  3. Prioritize removal of overbroad data permissions alongside platform vulnerability remediation.
  4. Separate datasets by sensitivity and apply least-privilege access and data movement controls.

Explanation

Correct Answer

A:

Risky data movement requires context-aware controls beyond source encryption. This choice directly fits the stated architecture requirement.

Incorrect Answers

B:

This recommendation fits a different scenario: A team immediately disables an entire shared data platform after one suspicious access alert without checking evidence. Evidence-based response reduces harm from both compromise and unnecessary shutdown. It does not solve the specified case, for which Design data exfiltration monitoring and destination restrictions based on data classification. is appropriate.

C:

This recommendation fits a different scenario: A security program patches database servers but ignores the excessive data-reader permissions granted to application service accounts. Compromised application identities can expose data even on fully patched servers. It does not solve the specified case, for which Design data exfiltration monitoring and destination restrictions based on data classification. is appropriate.

D:

This recommendation fits a different scenario: A hospital stores deidentified metrics and raw patient records in one account with identical sharing permissions. High-sensitivity records need protection proportionate to disclosure consequences. It does not solve the specified case, for which Design data exfiltration monitoring and destination restrictions based on data classification. is appropriate.

Question 136

An architecture approval board must resolve this concern: A web application firewall blocks one SQL injection pattern but its origin server remains reachable through a separate public IP. Which architecture recommendation BEST addresses the case?

  1. Remove direct origin exposure and enforce the supported WAF entry path.
  2. Configure appropriate WAF rate-limiting or bot protection rules with measured exception handling.
  3. Monitor WAF detections, false positives and managed rule updates with staged tuning.
  4. Evaluate Azure DDoS Protection with suitable public IP and network architecture.

Explanation

Correct Answer

A:

WAF policy cannot defend traffic routed around the protected edge. This choice directly fits the stated architecture requirement.

Incorrect Answers

B:

This recommendation fits a different scenario: An e-commerce application needs bot defense and rate limiting for repeated API requests rather than broad network port blocks. Layer-seven abuse controls evaluate HTTP behavior, not only packet ports. It does not solve the specified case, for which Remove direct origin exposure and enforce the supported WAF entry path. is appropriate.

C:

This recommendation fits a different scenario: A company deploys an edge WAF but never audits rule logs after legitimate customer requests begin failing. Protective rules need operational assurance to avoid undetected service disruption. It does not solve the specified case, for which Remove direct origin exposure and enforce the supported WAF entry path. is appropriate.

D:

This recommendation fits a different scenario: A high-traffic public web service is exposed to volumetric network floods beyond ordinary application request limits. Volumetric availability attacks require controls distinct from application-layer validation. It does not solve the specified case, for which Remove direct origin exposure and enforce the supported WAF entry path. is appropriate.

Question 137

A security engineering lead describes the following problem: A Cosmos DB workload embeds a full-account key in client applications distributed to external users. Which action is MOST appropriate for the stated need?

  1. Evaluate private connectivity, Microsoft Entra authentication and scoped database authorization.
  2. Replace client account keys with appropriate identity-based or service-mediated scoped access.
  3. Define workspace, SQL and storage data-plane entitlements separately for Synapse workloads.
  4. Include database auditing and threat detection in the data platform security design.

Explanation

Correct Answer

B:

Exposed account secrets permit operations beyond the intended end-user rights. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: An Azure SQL workload permits password access from the entire internet even though only managed Azure services need it. Reducing public access and shared credentials protects database entry points. It does not solve the specified case, for which Replace client account keys with appropriate identity-based or service-mediated scoped access. is appropriate.

C:

This recommendation fits a different scenario: A Synapse analytics workspace enables data access for every contributor role without distinct SQL or storage permissions. Workspace management permissions do not automatically express least-privilege access to underlying data. It does not solve the specified case, for which Replace client account keys with appropriate identity-based or service-mediated scoped access. is appropriate.

D:

This recommendation fits a different scenario: A database is encrypted and backed up, but audit trails for sensitive query activity are not retained. Confidentiality and recovery controls do not replace detection and attribution of data access. It does not solve the specified case, for which Replace client account keys with appropriate identity-based or service-mediated scoped access. is appropriate.

Question 138

A governance team has raised this design requirement: A workload team claims that a Defender for Cloud recommendation automatically proves every control in a security benchmark is satisfied. What should the cybersecurity architect recommend?

  1. Specify benchmark-aligned encryption and key management standards with consistent exception criteria.
  2. Establish periodic control reassessment when responsibility boundaries and managed-service assumptions change.
  3. Map Microsoft Cloud Security Benchmark control families to applicable workloads and required evidence.
  4. Validate effective configurations and compensating controls against the specific benchmark requirements.

Explanation

Correct Answer

D:

Product recommendations are signals, not definitive proof of complete control compliance. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A policy requires encryption but different teams interpret acceptable key custody in incompatible ways. Written control intent creates a shared basis for architecture evaluation and evidence. It does not solve the specified case, for which Validate effective configurations and compensating controls against the specific benchmark requirements. is appropriate.

B:

This recommendation fits a different scenario: An organization adopts a security benchmark but never revisits it after changing cloud service models. Required controls may shift between customer and provider as service models evolve. It does not solve the specified case, for which Validate effective configurations and compensating controls against the specific benchmark requirements. is appropriate.

C:

This recommendation fits a different scenario: Auditors receive a dashboard of deployed services but no mapping between controls and organizational security standards. Benchmark alignment relates deployed safeguards to measurable security obligations. It does not solve the specified case, for which Validate effective configurations and compensating controls against the specific benchmark requirements. is appropriate.

Question 139

A regulated organization needs a safer design because: An application team wants to deploy production Azure resources into any region without review. Which change MOST directly mitigates the design gap?

  1. Include policy-governed diagnostic settings and centralized log routing in landing-zone templates.
  2. Design a management-group hierarchy with standard landing-zone governance and approved exceptions.
  3. Enforce approved-region controls through appropriately scoped Azure Policy assignments.
  4. Define reusable least-privilege RBAC assignments at management-group, subscription and resource scopes.

Explanation

Correct Answer

C:

Location restrictions translate residency policy into preventive resource configuration. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A landing zone is provisioned without any central diagnostic or security event destination. Security telemetry needs to be established as part of the platform baseline, not added after an incident. It does not solve the specified case, for which Enforce approved-region controls through appropriately scoped Azure Policy assignments. is appropriate.

B:

This recommendation fits a different scenario: Developers are creating independent production subscriptions without consistent management-group policy inheritance. Inherited controls allow consistent organization-wide baselines while retaining workload delegation. It does not solve the specified case, for which Enforce approved-region controls through appropriately scoped Azure Policy assignments. is appropriate.

D:

This recommendation fits a different scenario: A new workload has only owner access assigned at subscription root, even though support duties are narrower. Granular role scoping avoids treating every operator as a subscription administrator. It does not solve the specified case, for which Enforce approved-region controls through appropriately scoped Azure Policy assignments. is appropriate.

Question 140

A cybersecurity architect is evaluating the following business requirement: Endpoint detectors become noisy after a new sensor rollout, and leadership believes attacks have doubled. Which architecture recommendation BEST addresses the case?

  1. Use evidence-based narrow tuning and regression tests rather than disabling the broad detection family.
  2. Enrich external indicators with local telemetry, time context and confidence before escalation.
  3. Normalize security metrics by monitored asset coverage and detection-rule changes.
  4. Design behavioral detections and threat-hunting hypotheses beyond one static indicator.

Explanation

Correct Answer

C:

Improved visibility can increase alert counts without a matching change in attacker activity. This choice directly fits the stated architecture requirement.

Incorrect Answers

A:

This recommendation fits a different scenario: A detection rule catches a false-positive administrative script, and the owner asks for blanket script exclusions. Scoped exceptions limit noise without removing visibility for genuine malicious variants. It does not solve the specified case, for which Normalize security metrics by monitored asset coverage and detection-rule changes. is appropriate.

B:

This recommendation fits a different scenario: A SOC promotes every external threat indicator to a high-severity alert without validating matches against tenant events. Intelligence relevance depends on actual environment observations rather than feed labels alone. It does not solve the specified case, for which Normalize security metrics by monitored asset coverage and detection-rule changes. is appropriate.

D:

This recommendation fits a different scenario: A malware campaign changes IP addresses while maintaining the same credential-theft technique. Technique-oriented analytics survive changes to attacker infrastructure. It does not solve the specified case, for which Normalize security metrics by monitored asset coverage and detection-rule changes. is appropriate.
