Microsoft SC-900 Practice Test 7

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.

Question 61

During a security controls rollout at a customer support provider, the risk manager records this concrete requirement: Several applications must rely on one trusted service to issue identity assertions for users. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Evaluate likelihood, impact, existing controls, and risk treatment choices before accepting or mitigating the exposure.
  2. Establish governance roles, approved control policies, and management review checkpoints.
  3. Keep tenant user access, data classification, and configuration controls under the customer's governance while the provider operates the SaaS service.
  4. Use an identity provider to authenticate identities and provide trusted identity claims to relying applications.

Explanation

Correct Answer

D:

Use an identity provider to authenticate identities and provide trusted identity claims to relying applications. An identity provider authenticates identities and supplies the identity information applications rely on. To verify, trace a sign-in through the provider and validate the relying application's accepted identity assertion.

Incorrect Answers

A:

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 identity provider.

B:

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 identity provider.

C:

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 identity provider.

Question 62

During a security controls rollout at a customer support provider, the risk manager records this concrete requirement: Several applications must rely on one trusted service to issue identity assertions for users. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Use an identity provider to authenticate identities and provide trusted identity claims to relying applications. 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. Map each threat path to independent controls and test whether another layer still reduces impact after one fails.
  3. Check guest patch compliance and the provider's published infrastructure responsibility scope separately.
  4. Review access-policy decisions and logs for both on-premises and remote requests with comparable risk signals.

Explanation

Correct Answer

A:

Trace a sign-in through the provider and validate the relying application's accepted identity assertion. An identity provider authenticates identities and supplies the identity information applications rely on.

Incorrect Answers

B:

Map each threat path to independent controls and test whether another layer still reduces impact after one fails. This would test defense in depth, whereas the required evidence is: Trace a sign-in through the provider and validate the relying application's accepted identity assertion.

C:

Check guest patch compliance and the provider's published infrastructure responsibility scope separately. This would test shared responsibility in IaaS, whereas the required evidence is: Trace a sign-in through the provider and validate the relying application's accepted identity assertion.

D:

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: Trace a sign-in through the provider and validate the relying application's accepted identity assertion.

Question 63

Following a quarterly control assessment at a financial software company, the technology auditor has to defend a design against oversimplified assumptions. The requirement is: Several applications must rely on one trusted service to issue identity assertions for users. 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. Encryption at rest protects stored content from unauthorized reading without claiming to control user authorization.
  2. An identity provider authenticates identities and supplies the identity information applications rely on.
  3. PaaS abstracts infrastructure management without removing the customer's application and data security decisions.
  4. Assume breach means design for detection and damage limitation even while preventive controls operate.

Explanation

Correct Answer

B:

An identity provider authenticates identities and supplies the identity information applications rely on. It explains why the selected measure—Use an identity provider to authenticate identities and provide trusted identity claims to relying applications—fits the specific requirement. It should be verified by checking: Trace a sign-in through the provider and validate the relying application's accepted identity assertion.

Incorrect Answers

A:

Encryption at rest protects stored content from unauthorized reading without claiming to control user authorization. This describes encryption at rest; the governing concept here is: An identity provider authenticates identities and supplies the identity information applications rely on.

C:

PaaS abstracts infrastructure management without removing the customer's application and data security decisions. This describes shared responsibility in PaaS; the governing concept here is: An identity provider authenticates identities and supplies the identity information applications rely on.

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: An identity provider authenticates identities and supplies the identity information applications rely on.

Question 64

Following a quarterly control assessment at a financial software company, the technology auditor has to defend a design against oversimplified assumptions. The requirement is: Several applications must rely on one trusted service to issue identity assertions for users. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Assuming encrypted disks also encrypt every network packet sent to an external endpoint.
  2. Treating physical office location as sufficient proof of identity and authorization.
  3. Assuming every application must independently store and validate every user's password.
  4. Treating provider-hosted SaaS as permission to ignore tenant access and data governance.

Explanation

Correct Answer

C:

Assuming every application must independently store and validate every user's password. This belief conflicts with this control principle: An identity provider authenticates identities and supplies the identity information applications rely on. The appropriate response instead is: Use an identity provider to authenticate identities and provide trusted identity claims to relying applications.

Incorrect Answers

A:

Assuming encrypted disks also encrypt every network packet sent to an external endpoint. That caution concerns encryption in transit; the specific misconception here is: Assuming every application must independently store and validate every user's password.

B:

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 application must independently store and validate every user's password.

D:

Treating provider-hosted SaaS as permission to ignore tenant access and data governance. That caution concerns shared responsibility in SaaS; the specific misconception here is: Assuming every application must independently store and validate every user's password.

Question 65

During a migration readiness meeting at a healthcare cooperative, the application administrator records this concrete requirement: An enterprise needs a managed directory of users, groups, and related identity attributes. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Use directory services to organize identity objects and make them discoverable to authorized systems.
  2. Keep responsibility for application code, user access, and data configuration while the platform provider maintains the underlying runtime and infrastructure.
  3. Plan containment, segmentation, continuous monitoring, and recovery as if some initial compromise may occur.
  4. Map regulatory requirements to controls, gather evidence, and document control exceptions.

Explanation

Correct Answer

A:

Use directory services to organize identity objects and make them discoverable to authorized systems. Directory services provide a structured identity store and lookup capabilities; they do not alone define every resource permission. To verify, query authorized directory entries and compare membership and attribute changes to the source of truth.

Incorrect Answers

B:

Keep responsibility for application code, user access, and data configuration while the platform provider maintains the underlying runtime and infrastructure. That addresses a different task: a development group moves an application to a managed platform and must assign duties for application code and identities. The present requirement concerns directory services.

C:

Plan containment, segmentation, continuous monitoring, and recovery as if some initial compromise may occur. That addresses a different task: a security team is designing controls for a possible stolen administrator token. The present requirement concerns directory services.

D:

Map regulatory requirements to controls, gather evidence, and document control exceptions. That addresses a different task: a regulated organization must demonstrate that required controls are operating against an external obligation. The present requirement concerns directory services.

Question 66

During a migration readiness meeting at a healthcare cooperative, the application administrator records this concrete requirement: An enterprise needs a managed directory of users, groups, and related identity attributes. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Use directory services to organize identity objects and make them discoverable to authorized systems. Which evidence BEST verifies that the action met its stated purpose?

  1. Recompute the artifact hash and compare it with the authenticated expected value.
  2. Query authorized directory entries and compare membership and attribute changes to the source of truth.
  3. Check guest patch compliance and the provider's published infrastructure responsibility scope separately.
  4. Review risk-register entries, decision ownership, residual risk, and the approved treatment plan.

Explanation

Correct Answer

B:

Query authorized directory entries and compare membership and attribute changes to the source of truth. Directory services provide a structured identity store and lookup capabilities; they do not alone define every resource permission.

Incorrect Answers

A:

Recompute the artifact hash and compare it with the authenticated expected value. This would test hashing versus encryption, whereas the required evidence is: Query authorized directory entries and compare membership and attribute changes to the source of truth.

C:

Check guest patch compliance and the provider's published infrastructure responsibility scope separately. This would test shared responsibility in IaaS, whereas the required evidence is: Query authorized directory entries and compare membership and attribute changes to the source of truth.

D:

Review risk-register entries, decision ownership, residual risk, and the approved treatment plan. This would test grc risk management, whereas the required evidence is: Query authorized directory entries and compare membership and attribute changes to the source of truth.

Question 67

Following a control design challenge at a public utility, the information governance lead has to defend a design against oversimplified assumptions. The requirement is: An enterprise needs a managed directory of users, groups, and related identity attributes. 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. Assume breach means design for detection and damage limitation even while preventive controls operate.
  2. Governance creates authority and accountability for managing information security and compliance activities.
  3. Directory services provide a structured identity store and lookup capabilities; they do not alone define every resource permission.
  4. Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate.

Explanation

Correct Answer

C:

Directory services provide a structured identity store and lookup capabilities; they do not alone define every resource permission. It explains why the selected measure—Use directory services to organize identity objects and make them discoverable to authorized systems—fits the specific requirement. It should be verified by checking: Query authorized directory entries and compare membership and attribute changes to the source of truth.

Incorrect Answers

A:

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: Directory services provide a structured identity store and lookup capabilities; they do not alone define every resource permission.

B:

Governance creates authority and accountability for managing information security and compliance activities. This describes grc governance; the governing concept here is: Directory services provide a structured identity store and lookup capabilities; they do not alone define every resource permission.

D:

Compliance focuses on meeting applicable obligations and demonstrating that required controls exist and operate. This describes grc compliance; the governing concept here is: Directory services provide a structured identity store and lookup capabilities; they do not alone define every resource permission.

Question 68

Following a control design challenge at a public utility, the information governance lead has to defend a design against oversimplified assumptions. The requirement is: An enterprise needs a managed directory of users, groups, and related identity attributes. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?

  1. Treating physical office location as sufficient proof of identity and authorization.
  2. Claiming a strong network edge eliminates the need for identity, endpoint, and data controls.
  3. Assuming an IaaS provider automatically patches every customer-controlled guest OS and application.
  4. Assuming a directory group entry automatically grants access to every resource without permission configuration.

Explanation

Correct Answer

D:

Assuming a directory group entry automatically grants access to every resource without permission configuration. This belief conflicts with this control principle: Directory services provide a structured identity store and lookup capabilities; they do not alone define every resource permission. The appropriate response instead is: Use directory services to organize identity objects and make them discoverable to authorized systems.

Incorrect Answers

A:

Treating physical office location as sufficient proof of identity and authorization. That caution concerns zero trust explicit verification; the specific misconception here is: Assuming a directory group entry automatically grants access to every resource without permission configuration.

B:

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 a directory group entry automatically grants access to every resource without permission configuration.

C:

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 a directory group entry automatically grants access to every resource without permission configuration.

Question 69

During an access-management redesign at a research institute, the incident responder records this concrete requirement: A partner's staff should use its existing organizational identity to access a separate service. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?

  1. Assign only the narrow permissions and duration needed for the operator's documented task.
  2. Establish a trusted federation relationship so the external identity provider can authenticate the partner users.
  3. Use supported encryption-at-rest controls with appropriate key protection for stored information.
  4. Combine complementary controls at identity, network, host, application, and data layers rather than relying on one perimeter.

Explanation

Correct Answer

B:

Establish a trusted federation relationship so the external identity provider can authenticate the partner users. Federation extends authentication trust across organizational or security boundaries. To verify, validate the trust configuration and sign-in tokens while confirming no separate local password is required.

Incorrect Answers

A:

Assign only the narrow permissions and duration needed for the operator's documented task. That addresses a different task: a helpdesk operator requests permanent global administrator access to do occasional password resets. The present requirement concerns federation.

C:

Use supported encryption-at-rest controls with appropriate key protection for stored information. That addresses a different task: a storage team must protect sensitive data on disks and backups if physical media is stolen. The present requirement concerns federation.

D:

Combine complementary controls at identity, network, host, application, and data layers rather than relying on one perimeter. That addresses a different task: an organization needs multiple compensating layers because any one defensive control might fail. The present requirement concerns federation.

Question 70

During an access-management redesign at a research institute, the incident responder records this concrete requirement: A partner's staff should use its existing organizational identity to access a separate service. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Establish a trusted federation relationship so the external identity provider can authenticate the partner users. Which evidence BEST verifies that the action met its stated purpose?

  1. Inspect storage encryption state and key access controls, then test a retrieval authorized by the key policy.
  2. Review application settings, identity permissions, and provider platform maintenance coverage separately.
  3. Validate the trust configuration and sign-in tokens while confirming no separate local password is required.
  4. Check guest patch compliance and the provider's published infrastructure responsibility scope separately.

Explanation

Correct Answer

C:

Validate the trust configuration and sign-in tokens while confirming no separate local password is required. Federation extends authentication trust across organizational or security boundaries.

Incorrect Answers

A:

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: Validate the trust configuration and sign-in tokens while confirming no separate local password is required.

B:

Review application settings, identity permissions, and provider platform maintenance coverage separately. This would test shared responsibility in PaaS, whereas the required evidence is: Validate the trust configuration and sign-in tokens while confirming no separate local password is required.

D:

Check guest patch compliance and the provider's published infrastructure responsibility scope separately. This would test shared responsibility in IaaS, whereas the required evidence is: Validate the trust configuration and sign-in tokens while confirming no separate local password is required.
