Microsoft SC-900 Practice Test 6

Question 50

During a pilot deployment at a municipal transit authority, the information governance lead records this concrete requirement: A regulated organization must demonstrate that required controls are operating against an external obligation. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Map regulatory requirements to controls, gather evidence, and document control exceptions. Which evidence BEST verifies that the action met its stated purpose?

  1. Trace a sign-in through the provider and validate the relying application's accepted identity assertion.
  2. Examine the obligation-to-control mapping and dated evidence of implementation and testing.
  3. Query authorized directory entries and compare membership and attribute changes to the source of truth.
  4. Validate the trust configuration and sign-in tokens while confirming no separate local password is required.

Explanation

Correct Answer

B:

Examine the obligation-to-control mapping and dated evidence of implementation and testing. Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate.

Incorrect Answers

A:

Trace a sign-in through the provider and validate the relying application's accepted identity assertion. This would test identity provider, whereas the required evidence is: Examine the obligation-to-control mapping and dated evidence of implementation and testing.

C:

Query authorized directory entries and compare membership and attribute changes to the source of truth. This would test directory services, whereas the required evidence is: Examine the obligation-to-control mapping and dated evidence of implementation and testing.

D:

Validate the trust configuration and sign-in tokens while confirming no separate local password is required. This would test federation, whereas the required evidence is: Examine the obligation-to-control mapping and dated evidence of implementation and testing.

Question 51

Following an internal access audit at a pharmaceutical distributor, the training coordinator has to defend a design against oversimplified assumptions. The requirement is: A regulated organization must demonstrate that required controls are operating against an external obligation. The review is limited to the control and concept described by this requirement. Which security, identity, or compliance principle MOST directly explains the appropriate approach?

  1. Single sign-on reuses an established authentication context across participating applications.
  2. An identity provider authenticates identities and supplies the identity information applications rely on.
  3. Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate.
  4. Modern cloud security commonly treats identity as a central control point rather than the physical network edge.

Explanation

Correct Answer

C:

Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate. It explains why the selected measure—Map regulatory requirements to controls, gather evidence, and document control exceptions—fits the specific requirement. It should be verified by checking: Examine the obligation-to-control mapping and dated evidence of implementation and testing.

Incorrect Answers

A:

Single sign-on reuses an established authentication context across participating applications. This describes single sign-on concept; the governing concept here is: Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate.

B:

An identity provider authenticates identities and supplies the identity information applications rely on. This describes identity provider; the governing concept here is: Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate.

D:

Modern cloud security commonly treats identity as a central control point rather than the physical network edge. This describes identity as security perimeter; the governing concept here is: Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate.

Question 52

Following an internal access audit at a pharmaceutical distributor, the training coordinator has to defend a design against oversimplified assumptions. The requirement is: A regulated organization must demonstrate that required controls are operating against an external obligation. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming a directory group entry automatically grants access to every resource without permission configuration.
  2. Assuming single sign-on automatically gives a user authorization to every connected application.
  3. Assuming federation requires copying all partner passwords into the receiving organization.
  4. Assuming a risk score by itself proves that every legal and contractual obligation is satisfied.

Explanation

Correct Answer

D:

Assuming a risk score by itself proves that every legal and contractual obligation is satisfied. This belief conflicts with this control principle: Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate. The appropriate response instead is: Map regulatory requirements to controls, gather evidence, and document control exceptions.

Incorrect Answers

A:

Assuming a directory group entry automatically grants access to every resource without permission configuration. That caution concerns directory services; the specific misconception here is: Assuming a risk score by itself proves that every legal and contractual obligation is satisfied.

B:

Assuming single sign-on automatically gives a user authorization to every connected application. That caution concerns single sign-on concept; the specific misconception here is: Assuming a risk score by itself proves that every legal and contractual obligation is satisfied.

C:

Assuming federation requires copying all partner passwords into the receiving organization. That caution concerns federation; the specific misconception here is: Assuming a risk score by itself proves that every legal and contractual obligation is satisfied.

Question 53

During a new service launch at a subscription media service, the security architect records this concrete requirement: A user enters a username but the service still needs assurance that the claimant owns the account. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Establish governance roles, approved control policies, and management review checkpoints.
  2. Perform authentication using an appropriate credential or authenticator before treating the claimant as the user.
  3. Have the customer maintain guest OS configuration, patching, and applications while the provider secures the physical infrastructure.
  4. Evaluate likelihood, impact, existing controls, and risk treatment choices before accepting or mitigating the exposure.

Explanation

Correct Answer

B:

Perform authentication using an appropriate credential or authenticator before treating the claimant as the user. Authentication establishes who or what is making an identity claim; it precedes authorization decisions. To verify, inspect successful authentication events and the factor or method that established the identity claim.

Incorrect Answers

A:

Establish governance roles, approved control policies, and management review checkpoints. That addresses a different task: a board needs accountable security policies, decision owners, and periodic oversight. The present requirement concerns authentication.

C:

Have the customer maintain guest OS configuration, patching, and applications while the provider secures the physical infrastructure. That addresses a different task: a business deploys virtual machines and asks whether the cloud host will patch the guest operating system. The present requirement concerns authentication.

D:

Evaluate likelihood, impact, existing controls, and risk treatment choices before accepting or mitigating the exposure. That addresses a different task: a service team must prioritize treatment of a threat that has high business impact but uncertain likelihood. The present requirement concerns authentication.

Question 54

During a new service launch at a subscription media service, the security architect records this concrete requirement: A user enters a username but the service still needs assurance that the claimant owns the account. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Perform authentication using an appropriate credential or authenticator before treating the claimant as the user. Which evidence BEST verifies that the action met its stated purpose?

  1. Review access-policy decisions and logs for both on-premises and remote requests with comparable risk signals.
  2. Examine the obligation-to-control mapping and dated evidence of implementation and testing.
  3. Inspect successful authentication events and the factor or method that established the identity claim.
  4. Run a simulated compromise and confirm lateral movement is limited and response telemetry is available.

Explanation

Correct Answer

C:

Inspect successful authentication events and the factor or method that established the identity claim. Authentication establishes who or what is making an identity claim; it precedes authorization decisions.

Incorrect Answers

A:

Review access-policy decisions and logs for both on-premises and remote requests with comparable risk signals. This would test zero trust explicit verification, whereas the required evidence is: Inspect successful authentication events and the factor or method that established the identity claim.

B:

Examine the obligation-to-control mapping and dated evidence of implementation and testing. This would test grc compliance, whereas the required evidence is: Inspect successful authentication events and the factor or method that established the identity claim.

D:

Run a simulated compromise and confirm lateral movement is limited and response telemetry is available. This would test zero trust assume breach, whereas the required evidence is: Inspect successful authentication events and the factor or method that established the identity claim.

Question 55

Following a peer architecture review at a managed services company, the cloud platform manager has to defend a design against oversimplified assumptions. The requirement is: A user enters a username but the service still needs assurance that the claimant owns the account. The review is limited to the control and concept described by this requirement. Which security, identity, or compliance principle MOST directly explains the appropriate approach?

  1. Risk management is the structured identification, evaluation, and treatment of uncertainty to business objectives.
  2. Assume breach means design for detection and damage limitation even while preventive controls operate.
  3. Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate.
  4. Authentication establishes who or what is making an identity claim; it precedes authorization decisions.

Explanation

Correct Answer

D:

Authentication establishes who or what is making an identity claim; it precedes authorization decisions. It explains why the selected measure—Perform authentication using an appropriate credential or authenticator before treating the claimant as the user—fits the specific requirement. It should be verified by checking: Inspect successful authentication events and the factor or method that established the identity claim.

Incorrect Answers

A:

Risk management is the structured identification, evaluation, and treatment of uncertainty to business objectives. This describes grc risk management; the governing concept here is: Authentication establishes who or what is making an identity claim; it precedes authorization decisions.

B:

Assume breach means design for detection and damage limitation even while preventive controls operate. This describes zero trust assume breach; the governing concept here is: Authentication establishes who or what is making an identity claim; it precedes authorization decisions.

C:

Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate. This describes grc compliance; the governing concept here is: Authentication establishes who or what is making an identity claim; it precedes authorization decisions.

Question 56

Following a peer architecture review at a managed services company, the cloud platform manager has to defend a design against oversimplified assumptions. The requirement is: A user enters a username but the service still needs assurance that the claimant owns the account. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Mistaking possession of a username for proof the claimant is authenticated.
  2. Assuming disk encryption alone prevents an authorized but malicious signed-in user from reading data.
  3. Claiming a strong network edge eliminates the need for identity, endpoint, and data controls.
  4. Assuming an IaaS provider automatically patches every customer-controlled guest OS and application.

Explanation

Correct Answer

A:

Mistaking possession of a username for proof the claimant is authenticated. This belief conflicts with this control principle: Authentication establishes who or what is making an identity claim; it precedes authorization decisions. The appropriate response instead is: Perform authentication using an appropriate credential or authenticator before treating the claimant as the user.

Incorrect Answers

B:

Assuming disk encryption alone prevents an authorized but malicious signed-in user from reading data. That caution concerns encryption at rest; the specific misconception here is: Mistaking possession of a username for proof the claimant is authenticated.

C:

Claiming a strong network edge eliminates the need for identity, endpoint, and data controls. That caution concerns defense in depth; the specific misconception here is: Mistaking possession of a username for proof the claimant is authenticated.

D:

Assuming an IaaS provider automatically patches every customer-controlled guest OS and application. That caution concerns shared responsibility in IaaS; the specific misconception here is: Mistaking possession of a username for proof the claimant is authenticated.

Question 57

During a tenant consolidation at an industrial design firm, the compliance analyst records this concrete requirement: A correctly signed-in employee requests access to a confidential payroll folder. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Establish governance roles, approved control policies, and management review checkpoints.
  2. Evaluate identity, device, resource, and contextual signals for each access request instead of relying on network location alone.
  3. Evaluate the employee's permissions and resource policy before granting access to the folder.
  4. Keep tenant user access, data classification, and configuration controls under the customer's governance while the provider operates the SaaS service.

Explanation

Correct Answer

C:

Evaluate the employee's permissions and resource policy before granting access to the folder. Authorization determines what an authenticated identity may do to a given resource. To verify, test access as authorized and unauthorized identities and verify permission evaluations differ correctly.

Incorrect Answers

A:

Establish governance roles, approved control policies, and management review checkpoints. That addresses a different task: a board needs accountable security policies, decision owners, and periodic oversight. The present requirement concerns authorization.

B:

Evaluate identity, device, resource, and contextual signals for each access request instead of relying on network location alone. That addresses a different task: a team proposes trusting all requests originating from a corporate office subnet. The present requirement concerns authorization.

D:

Keep tenant user access, data classification, and configuration controls under the customer's governance while the provider operates the SaaS service. That addresses a different task: a subscriber to a SaaS application must decide who governs employees' access and the information they upload. The present requirement concerns authorization.

Question 58

During a tenant consolidation at an industrial design firm, the compliance analyst records this concrete requirement: A correctly signed-in employee requests access to a confidential payroll folder. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Evaluate the employee's permissions and resource policy before granting access to the folder. Which evidence BEST verifies that the action met its stated purpose?

  1. Inspect the tenant access assignments, information protection rules, and provider documentation for the responsibility boundary.
  2. Review access-policy decisions and logs for both on-premises and remote requests with comparable risk signals.
  3. Inspect storage encryption state and key access controls, then test a retrieval authorized by the key policy.
  4. Test access as authorized and unauthorized identities and verify permission evaluations differ correctly.

Explanation

Correct Answer

D:

Test access as authorized and unauthorized identities and verify permission evaluations differ correctly. Authorization determines what an authenticated identity may do to a given resource.

Incorrect Answers

A:

Inspect the tenant access assignments, information protection rules, and provider documentation for the responsibility boundary. This would test shared responsibility in SaaS, whereas the required evidence is: Test access as authorized and unauthorized identities and verify permission evaluations differ correctly.

B:

Review access-policy decisions and logs for both on-premises and remote requests with comparable risk signals. This would test zero trust explicit verification, whereas the required evidence is: Test access as authorized and unauthorized identities and verify permission evaluations differ correctly.

C:

Inspect storage encryption state and key access controls, then test a retrieval authorized by the key policy. This would test encryption at rest, whereas the required evidence is: Test access as authorized and unauthorized identities and verify permission evaluations differ correctly.

Question 59

Following a technical incident debrief at a national retailer, the IT operations director has to defend a design against oversimplified assumptions. The requirement is: A correctly signed-in employee requests access to a confidential payroll folder. The review is limited to the control and concept described by this requirement. Which security, identity, or compliance principle MOST directly explains the appropriate approach?

  1. Authorization determines what an authenticated identity may do to a given resource.
  2. Least privilege minimizes standing permissions, attack surface, and impact if an account is compromised.
  3. Hashing supports integrity comparison; it is not a reversible confidentiality mechanism.
  4. Assume breach means design for detection and damage limitation even while preventive controls operate.

Explanation

Correct Answer

A:

Authorization determines what an authenticated identity may do to a given resource. It explains why the selected measure—Evaluate the employee's permissions and resource policy before granting access to the folder—fits the specific requirement. It should be verified by checking: Test access as authorized and unauthorized identities and verify permission evaluations differ correctly.

Incorrect Answers

B:

Least privilege minimizes standing permissions, attack surface, and impact if an account is compromised. This describes zero trust least privilege; the governing concept here is: Authorization determines what an authenticated identity may do to a given resource.

C:

Hashing supports integrity comparison; it is not a reversible confidentiality mechanism. This describes hashing versus encryption; the governing concept here is: Authorization determines what an authenticated identity may do to a given resource.

D:

Assume breach means design for detection and damage limitation even while preventive controls operate. This describes zero trust assume breach; the governing concept here is: Authorization determines what an authenticated identity may do to a given resource.

Question 60

Following a technical incident debrief at a national retailer, the IT operations director has to defend a design against oversimplified assumptions. The requirement is: A correctly signed-in employee requests access to a confidential payroll folder. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Claiming a strong network edge eliminates the need for identity, endpoint, and data controls.
  2. Assuming every authenticated employee has permission to read every organizational file.
  3. Treating physical office location as sufficient proof of identity and authorization.
  4. Assuming an IaaS provider automatically patches every customer-controlled guest OS and application.

Explanation

Correct Answer

B:

Assuming every authenticated employee has permission to read every organizational file. This belief conflicts with this control principle: Authorization determines what an authenticated identity may do to a given resource. The appropriate response instead is: Evaluate the employee's permissions and resource policy before granting access to the folder.

Incorrect Answers

A:

Claiming a strong network edge eliminates the need for identity, endpoint, and data controls. That caution concerns defense in depth; the specific misconception here is: Assuming every authenticated employee has permission to read every organizational file.

C:

Treating physical office location as sufficient proof of identity and authorization. That caution concerns zero trust explicit verification; the specific misconception here is: Assuming every authenticated employee has permission to read every organizational file.

D:

Assuming an IaaS provider automatically patches every customer-controlled guest OS and application. That caution concerns shared responsibility in IaaS; the specific misconception here is: Assuming every authenticated employee has permission to read every organizational file.
