Sample Exam Questions

Try these 12 original sample questions for Microsoft SC-900. They are designed for self-assessment and are not official exam questions.

Question 1

Topic: security fundamentals

A manager asks why identity is central to Microsoft security. Which answer is strongest?

  • A. Identity controls who can access resources and is a core enforcement point for Zero Trust.
  • B. Identity matters only for email branding.
  • C. Identity replaces all network and data controls.
  • D. Identity is unrelated to cloud security.

Best answer: A

Explanation: SC-900 is fundamentals-level, so it rewards recognizing identity as a core security boundary without overstating it as the only control.

What this tests: Microsoft security and identity fundamentals.


Question 2

Topic: Zero Trust

Which statement best describes Zero Trust?

  • A. Trust every device inside the office network.
  • B. Verify explicitly, use least privilege, and assume breach rather than trusting by network location.
  • C. Disable MFA to improve productivity.
  • D. Give users permanent administrator access.

Best answer: B

Explanation: Zero Trust combines explicit verification, least privilege, and breach-aware design. It is not a single product or a perimeter-only model.

What this tests: Zero Trust principles.


Question 3

Topic: Microsoft Entra

A company wants single sign-on and conditional access for cloud apps. Which Microsoft platform is most relevant?

  • A. Azure Cost Management only.
  • B. Microsoft Planner only.
  • C. Microsoft Entra ID.
  • D. A local spreadsheet of users.

Best answer: C

Explanation: Microsoft Entra ID provides identity, authentication, conditional access, and SSO capabilities for Microsoft cloud environments.

What this tests: Recognizing Microsoft identity services.


Question 4

Topic: Microsoft Defender

A security team wants endpoint threat detection and response across user devices. Which product family is most relevant?

  • A. Microsoft Forms.
  • B. Azure DNS only.
  • C. A storage lifecycle policy.
  • D. Microsoft Defender.

Best answer: D

Explanation: Microsoft Defender includes endpoint and XDR capabilities. SC-900 candidates should know broad product-family fit.

What this tests: Matching security needs to Microsoft security product families.


Question 5

Topic: Microsoft Purview

A compliance team needs data classification, sensitivity labels, and retention controls. Which Microsoft family is most relevant?

  • A. Microsoft Purview.
  • B. Azure Virtual Desktop only.
  • C. GitHub Actions only.
  • D. Azure Bastion only.

Best answer: A

Explanation: Purview is the Microsoft compliance, information protection, data governance, and risk-management family.

What this tests: Recognizing compliance and information-protection tooling.


Question 6

Topic: MFA

A user password is stolen. Which control most directly reduces the chance that the stolen password alone grants access?

  • A. A shorter username.
  • B. Multi-factor authentication.
  • C. A larger mailbox.
  • D. A public IP address.

Best answer: B

Explanation: MFA requires another proof beyond the password. It is a common baseline control in identity security.

What this tests: Understanding authentication controls.


Question 7

Topic: shared responsibility

In cloud security, what does shared responsibility mean?

  • A. The provider owns every security decision.
  • B. The customer owns nothing after moving to cloud.
  • C. The cloud provider and customer each own different security responsibilities depending on the service model.
  • D. Only auditors own cloud security.

Best answer: C

Explanation: Shared responsibility clarifies who manages physical, platform, identity, data, and configuration controls.

What this tests: Cloud shared-responsibility concepts.


Question 8

Topic: least privilege

A user needs to read compliance reports but not change policies. What is the best access principle?

  • A. Make the user a global administrator.
  • B. Share the compliance administrator password.
  • C. Disable audit logging.
  • D. Grant only the permissions needed for the reporting task.

Best answer: D

Explanation: Least privilege limits access to what is needed. This reduces accidental and malicious risk.

What this tests: Applying least privilege.


Question 9

Topic: SIEM basics

A team wants to collect security events, correlate detections, and investigate incidents. Which tool category fits?

  • A. SIEM and security operations tooling such as Microsoft Sentinel.
  • B. A presentation template.
  • C. A billing export only.
  • D. A desktop wallpaper service.

Best answer: A

Explanation: Sentinel is Microsoft’s cloud-native SIEM/SOAR option. The fundamentals route expects category recognition.

What this tests: Understanding security operations tooling.


Question 10

Topic: compliance

A regulation requires proof of access reviews and audit records. What should the organization maintain?

  • A. Only informal chat messages.
  • B. Auditable controls, review evidence, and reporting aligned to the requirement.
  • C. No records to reduce storage.
  • D. A public link to all data.

Best answer: B

Explanation: Compliance depends on implemented controls and evidence. The answer should preserve auditability.

What this tests: Connecting compliance requirements to evidence.


Question 11

Topic: data protection

A file contains confidential customer information. What should be considered first?

  • A. Publishing the file publicly.
  • B. Removing all labels.
  • C. Classification, access controls, encryption, retention, and sharing restrictions.
  • D. Ignoring data location and ownership.

Best answer: C

Explanation: Data protection is layered. Classification helps drive access, encryption, sharing, and lifecycle decisions.

What this tests: Data-security fundamentals.


Question 12

Topic: route fit

A candidate is new to Microsoft security and wants fundamentals before analyst or architect paths. Which route is the closest fit?

  • A. SC-100 only.
  • B. AZ-120 only.
  • C. MB-330 only.
  • D. SC-900.

Best answer: D

Explanation: SC-900 is the fundamentals route for security, compliance, and identity. Advanced routes assume more role-specific knowledge.

What this tests: Choosing the correct Microsoft security route.
