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?
- Inspect storage encryption state and key access controls, then test a retrieval authorized by the key policy.
- Review application settings, identity permissions, and provider platform maintenance coverage separately.
- Validate the trust configuration and sign-in tokens while confirming no separate local password is required.
- 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.
Question 71
Following a privileged access audit at a hospitality operator, the security architect has to defend a design against oversimplified assumptions. The requirement is: A partner's staff should use its existing organizational identity to access a separate service. 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?
- Defense in depth deliberately layers independent protection so a single compromised control does not expose every asset.
- Encryption in transit addresses exposure of data traveling over a communication channel.
- Hashing supports integrity comparison; it is not a reversible confidentiality mechanism.
- Federation extends authentication trust across organizational or security boundaries.
Explanation
Correct Answer
D:Federation extends authentication trust across organizational or security boundaries. It explains why the selected measure—Establish a trusted federation relationship so the external identity provider can authenticate the partner users—fits the specific requirement. It should be verified by checking: Validate the trust configuration and sign-in tokens while confirming no separate local password is required.
Incorrect Answers
A:Defense in depth deliberately layers independent protection so a single compromised control does not expose every asset. This describes defense in depth; the governing concept here is: Federation extends authentication trust across organizational or security boundaries.
B:Encryption in transit addresses exposure of data traveling over a communication channel. This describes encryption in transit; the governing concept here is: Federation extends authentication trust across organizational or security boundaries.
C:Hashing supports integrity comparison; it is not a reversible confidentiality mechanism. This describes hashing versus encryption; the governing concept here is: Federation extends authentication trust across organizational or security boundaries.
Question 72
Following a privileged access audit at a hospitality operator, the security architect has to defend a design against oversimplified assumptions. The requirement is: A partner's staff should use its existing organizational identity to access a separate service. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?
- Assuming federation requires copying all partner passwords into the receiving organization.
- Believing a successful login proves no adversary can already be present in the environment.
- Assuming an IaaS provider automatically patches every customer-controlled guest OS and application.
- Assuming broad permanent administrative access is acceptable because it saves helpdesk time.
Explanation
Correct Answer
A:Assuming federation requires copying all partner passwords into the receiving organization. This belief conflicts with this control principle: Federation extends authentication trust across organizational or security boundaries. The appropriate response instead is: Establish a trusted federation relationship so the external identity provider can authenticate the partner users.
Incorrect Answers
B:Believing a successful login proves no adversary can already be present in the environment. That caution concerns zero trust assume breach; the specific misconception here is: Assuming federation requires copying all partner passwords into the receiving organization.
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 federation requires copying all partner passwords into the receiving organization.
D:Assuming broad permanent administrative access is acceptable because it saves helpdesk time. That caution concerns zero trust least privilege; the specific misconception here is: Assuming federation requires copying all partner passwords into the receiving organization.
Question 73
During a cloud governance workshop at a regional insurer, the identity administrator records this concrete requirement: Remote workers use cloud services from networks not managed by the enterprise. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?
- Compare a trusted cryptographic digest with a newly computed digest for the received artifact.
- Evaluate likelihood, impact, existing controls, and risk treatment choices before accepting or mitigating the exposure.
- Base access protection on user and workload identities with contextual policy rather than only network location.
- Use supported encryption-at-rest controls with appropriate key protection for stored information.
Explanation
Correct Answer
C:Base access protection on user and workload identities with contextual policy rather than only network location. Modern cloud security commonly treats identity as a central control point rather than the physical network edge. To verify, verify that access decisions still enforce identity-centric requirements from home, office, and mobile networks.
Incorrect Answers
A:Compare a trusted cryptographic digest with a newly computed digest for the received artifact. That addresses a different task: an auditor wants to detect whether a downloaded artifact changed rather than recover original plaintext. The present requirement concerns identity as security perimeter.
B: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 as security perimeter.
D: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 identity as security perimeter.

Question 75
Following a tabletop exercise at a cloud migration consultancy, the compliance analyst has to defend a design against oversimplified assumptions. The requirement is: Remote workers use cloud services from networks not managed by the enterprise. 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?
- Modern cloud security commonly treats identity as a central control point rather than the physical network edge.
- Using SaaS shifts underlying service operation to the provider but does not transfer responsibility for customer identities or data use.
- Assume breach means design for detection and damage limitation even while preventive controls operate.
- PaaS abstracts infrastructure management without removing the customer's application and data security decisions.
Explanation
Correct Answer
A:Modern cloud security commonly treats identity as a central control point rather than the physical network edge. It explains why the selected measure—Base access protection on user and workload identities with contextual policy rather than only network location—fits the specific requirement. It should be verified by checking: Verify that access decisions still enforce identity-centric requirements from home, office, and mobile networks.
Incorrect Answers
B:Using SaaS shifts underlying service operation to the provider but does not transfer responsibility for customer identities or data use. This describes shared responsibility in SaaS; the governing concept here is: Modern cloud security commonly treats identity as a central control point rather than the physical network edge.
C: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: Modern cloud security commonly treats identity as a central control point rather than the physical network edge.

Question 76
Following a tabletop exercise at a cloud migration consultancy, the compliance analyst has to defend a design against oversimplified assumptions. The requirement is: Remote workers use cloud services from networks not managed by the enterprise. The review is limited to the control and concept described by this requirement. Which unsupported assumption would MOST directly undermine this requirement?
- Claiming a strong network edge eliminates the need for identity, endpoint, and data controls.
- Treating corporate IP address membership as the sole security perimeter for cloud resources.
- Assuming an IaaS provider automatically patches every customer-controlled guest OS and application.
- Assuming disk encryption alone prevents an authorized but malicious signed-in user from reading data.
Explanation
Correct Answer
B:Treating corporate IP address membership as the sole security perimeter for cloud resources. This belief conflicts with this control principle: Modern cloud security commonly treats identity as a central control point rather than the physical network edge. The appropriate response instead is: Base access protection on user and workload identities with contextual policy rather than only network location.

Question 77
During a vendor assurance review at a legal services firm, the SOC lead records this concrete requirement: A staff member needs to open several approved cloud apps without repeated independent sign-ins. The solution must address this requirement directly, without replacing unrelated controls. Which primary response BEST meets the requirement?
- Plan containment, segmentation, continuous monitoring, and recovery as if some initial compromise may occur.
- Keep responsibility for application code, user access, and data configuration while the platform provider maintains the underlying runtime and infrastructure.
- Evaluate identity, device, resource, and contextual signals for each access request instead of relying on network location alone.
- Configure trusted single sign-on across applications that accept the identity provider's session or tokens.
Explanation
Correct Answer
D:Configure trusted single sign-on across applications that accept the identity provider's session or tokens. Single sign-on reuses an established authentication context across participating applications. To verify, sign in once and validate access to multiple correctly integrated apps under one identity session.
Incorrect Answers
A: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 single sign-on concept.
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 single sign-on concept.
C: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 single sign-on concept.
Question 78

The solution must address this requirement directly, without replacing unrelated controls. The team implements the following response: Configure trusted single sign-on across applications that accept the identity provider's session or tokens. Which evidence BEST verifies that the action met its stated purpose?
- Sign in once and validate access to multiple correctly integrated apps under one identity session.
- Check certificate validation and negotiated secure transport on the actual client-to-service path.
- Review role assignments, scope, and expiration against the specific support duties.
- Run a simulated compromise and confirm lateral movement is limited and response telemetry is available.
Explanation
Correct Answer
A:Sign in once and validate access to multiple correctly integrated apps under one identity session. Single sign-on reuses an established authentication context across participating applications.
Incorrect Answers
B:Check certificate validation and negotiated secure transport on the actual client-to-service path. This would test encryption in transit, whereas the required evidence is: Sign in once and validate access to multiple correctly integrated apps under one identity session.
C:Review role assignments, scope, and expiration against the specific support duties. This would test zero trust least privilege, whereas the required evidence is: Sign in once and validate access to multiple correctly integrated apps under one identity session.
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: Sign in once and validate access to multiple correctly integrated apps under one identity session.
