Question 10
During a cloud governance workshop at a school district, the application administrator records this concrete requirement: A development group moves an application to a managed platform and must assign duties for application code and identities. The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Keep responsibility for application code, user access, and data configuration while the platform provider maintains the underlying runtime and infrastructure. Which evidence BEST verifies that the action met its stated purpose?
- Inspect successful authentication events and the factor or method that established the identity claim.
- Verify that access decisions still enforce identity-centric requirements from home, office, and mobile networks.
- Test access as authorized and unauthorized identities and verify permission evaluations differ correctly.
- Review application settings, identity permissions, and provider platform maintenance coverage separately.
Explanation
Correct Answer
D:Review application settings, identity permissions, and provider platform maintenance coverage separately. PaaS abstracts infrastructure management without removing the customer's application and data security decisions.
Incorrect Answers
A:Inspect successful authentication events and the factor or method that established the identity claim. This would test authentication, whereas the required evidence is: Review application settings, identity permissions, and provider platform maintenance coverage separately.
B:Verify that access decisions still enforce identity-centric requirements from home, office, and mobile networks. This would test identity as security perimeter, whereas the required evidence is: Review application settings, identity permissions, and provider platform maintenance coverage separately.
C:Test access as authorized and unauthorized identities and verify permission evaluations differ correctly. This would test authorization, whereas the required evidence is: Review application settings, identity permissions, and provider platform maintenance coverage separately.
Question 11
Following a tabletop exercise at a public university, the information governance lead has to defend a design against oversimplified assumptions. The requirement is: A development group moves an application to a managed platform and must assign duties for application code and identities. 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?
- PaaS abstracts infrastructure management without removing the customer's application and data security decisions.
- Federation extends authentication trust across organizational or security boundaries.
- An identity provider authenticates identities and supplies the identity information applications rely on.
- Authorization determines what an authenticated identity may do to a given resource.
Explanation
Correct Answer
A:PaaS abstracts infrastructure management without removing the customer's application and data security decisions. It explains why the selected measure—Keep responsibility for application code, user access, and data configuration while the platform provider maintains the underlying runtime and infrastructure—fits the specific requirement. It should be verified by checking: Review application settings, identity permissions, and provider platform maintenance coverage separately.
Incorrect Answers
B:Federation extends authentication trust across organizational or security boundaries. This describes federation; the governing concept here is: PaaS abstracts infrastructure management without removing the customer's application and data security decisions.
C:An identity provider authenticates identities and supplies the identity information applications rely on. This describes identity provider; the governing concept here is: PaaS abstracts infrastructure management without removing the customer's application and data security decisions.
D:Authorization determines what an authenticated identity may do to a given resource. This describes authorization; the governing concept here is: PaaS abstracts infrastructure management without removing the customer's application and data security decisions.
Question 12
Following a tabletop exercise at a public university, the information governance lead has to defend a design against oversimplified assumptions. The requirement is: A development group moves an application to a managed platform and must assign duties for application code and identities. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?
- Mistaking possession of a username for proof the claimant is authenticated.
- Assuming managed runtimes automatically secure every application permission and data-handling decision.
- Assuming single sign-on automatically gives a user authorization to every connected application.
- Assuming a directory group entry automatically grants access to every resource without permission configuration.
Explanation
Correct Answer
B:Assuming managed runtimes automatically secure every application permission and data-handling decision. This belief conflicts with this control principle: PaaS abstracts infrastructure management without removing the customer's application and data security decisions. The appropriate response instead is: Keep responsibility for application code, user access, and data configuration while the platform provider maintains the underlying runtime and infrastructure.
Incorrect Answers
A:Mistaking possession of a username for proof the claimant is authenticated. That caution concerns authentication; the specific misconception here is: Assuming managed runtimes automatically secure every application permission and data-handling decision.
C: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 managed runtimes automatically secure every application permission and data-handling decision.
D: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 managed runtimes automatically secure every application permission and data-handling decision.
Question 13
During a vendor assurance review at a pharmaceutical distributor, the incident responder records this concrete requirement: An organization needs multiple compensating layers because any one defensive control might fail. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?
- Configure trusted single sign-on across applications that accept the identity provider's session or tokens.
- Use an identity provider to authenticate identities and provide trusted identity claims to relying applications.
- Establish a trusted federation relationship so the external identity provider can authenticate the partner users.
- Combine complementary controls at identity, network, host, application, and data layers rather than relying on one perimeter.
Explanation
Correct Answer
D:Combine complementary controls at identity, network, host, application, and data layers rather than relying on one perimeter. Defense in depth deliberately layers independent protection so a single compromised control does not expose every asset. To verify, map each threat path to independent controls and test whether another layer still reduces impact after one fails.
Incorrect Answers
A:Configure trusted single sign-on across applications that accept the identity provider's session or tokens. That addresses a different task: a staff member needs to open several approved cloud apps without repeated independent sign-ins. The present requirement concerns defense in depth.
B:Use an identity provider to authenticate identities and provide trusted identity claims to relying applications. That addresses a different task: several applications must rely on one trusted service to issue identity assertions for users. The present requirement concerns defense in depth.
C:Establish a trusted federation relationship so the external identity provider can authenticate the partner users. That addresses a different task: a partner's staff should use its existing organizational identity to access a separate service. The present requirement concerns defense in depth.

- Validate the trust configuration and sign-in tokens while confirming no separate local password is required.
- Inspect successful authentication events and the factor or method that established the identity claim.
Explanation
Correct Answer
A:Map each threat path to independent controls and test whether another layer still reduces impact after one fails. Defense in depth deliberately layers independent protection so a single compromised control does not expose every asset.
Incorrect Answers
B: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: Map each threat path to independent controls and test whether another layer still reduces impact after one fails.
C: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: Map each threat path to independent controls and test whether another layer still reduces impact after one fails.
D:Inspect successful authentication events and the factor or method that established the identity claim. This would test authentication, whereas the required evidence is: Map each threat path to independent controls and test whether another layer still reduces impact after one fails.

- Assuming a directory group entry automatically grants access to every resource without permission configuration.
- Claiming a strong network edge eliminates the need for identity, endpoint, and data controls.
- Assuming every application must independently store and validate every user's password.
Explanation
Correct Answer
C:Claiming a strong network edge eliminates the need for identity, endpoint, and data controls. This belief conflicts with this control principle: Defense in depth deliberately layers independent protection so a single compromised control does not expose every asset. The appropriate response instead is: Combine complementary controls at identity, network, host, application, and data layers rather than relying on one perimeter.
Incorrect Answers
A:Mistaking possession of a username for proof the claimant is authenticated. That caution concerns authentication; the specific misconception here is: Claiming a strong network edge eliminates the need for identity, endpoint, and data controls.

Question 17
During an infrastructure modernization effort at a managed services company, the identity administrator records this concrete requirement: A team proposes trusting all requests originating from a corporate office subnet. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?
- Evaluate identity, device, resource, and contextual signals for each access request instead of relying on network location alone.
- Base access protection on user and workload identities with contextual policy rather than only network location.
- Use directory services to organize identity objects and make them discoverable to authorized systems.
- Use an identity provider to authenticate identities and provide trusted identity claims to relying applications.
Explanation
Correct Answer
A:Evaluate identity, device, resource, and contextual signals for each access request instead of relying on network location alone. Zero Trust says verify explicitly, not trust requests because they originated inside a familiar network. To verify, review access-policy decisions and logs for both on-premises and remote requests with comparable risk signals.
Incorrect Answers
B:Base access protection on user and workload identities with contextual policy rather than only network location. That addresses a different task: remote workers use cloud services from networks not managed by the enterprise. The present requirement concerns zero trust explicit verification.
C:Use directory services to organize identity objects and make them discoverable to authorized systems. That addresses a different task: an enterprise needs a managed directory of users, groups, and related identity attributes. The present requirement concerns zero trust explicit verification.
D:Use an identity provider to authenticate identities and provide trusted identity claims to relying applications. That addresses a different task: several applications must rely on one trusted service to issue identity assertions for users. The present requirement concerns zero trust explicit verification.

- Query authorized directory entries and compare membership and attribute changes to the source of truth.
Explanation
Correct Answer
B:Review access-policy decisions and logs for both on-premises and remote requests with comparable risk signals. Zero Trust says verify explicitly, not trust requests because they originated inside a familiar network.
Incorrect Answers
A:Verify that access decisions still enforce identity-centric requirements from home, office, and mobile networks. This would test identity as security perimeter, whereas the required evidence is: Review access-policy decisions and logs for both on-premises and remote requests with comparable risk signals.
C: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: Review access-policy decisions and logs for both on-premises and remote requests with comparable risk signals.
D: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: Review access-policy decisions and logs for both on-premises and remote requests with comparable risk signals.
Question 19
Following a privacy readiness assessment at a retail payments business, the compliance analyst has to defend a design against oversimplified assumptions. The requirement is: A team proposes trusting all requests originating from a corporate office subnet. The review is limited to the control and concept described by this requirement.
