Question 530
Users can run arbitrary unsigned executables on sensitive workstations. What approach should the accountable team prioritize?
- Screen lock and idle timeout
- Application allowlisting
- Endpoint device control
- Secure configuration baseline
Explanation
Correct Answer
B:Allowlisting restricts execution to verified approved applications or publisher rules. By contrast, Screen lock and idle timeout is relevant when unattended logged-in terminals are accessible in shared office areas, not as a substitute for Application allowlisting in this case.
Incorrect Answers
A:Automatic locking limits casual unauthorized use of active authenticated sessions; deploying it would matter if unattended logged-in terminals are accessible in shared office areas, but the deciding issue here is that users can run arbitrary unsigned executables on sensitive workstations.
C:Device controls constrain removable media use based on policy and business requirements; it would be a fit if sensitive workstations allow unmonitored transfer to removable storage, whereas the required response must deal with the fact that users can run arbitrary unsigned executables on sensitive workstations.
D:A controlled baseline specifies supported hardened settings and review exceptions; this is pertinent when new endpoints retain unnecessary services and weak default settings, in contrast with the actual gap where users can run arbitrary unsigned executables on sensitive workstations.
Question 531
Staff routinely use high-privilege local accounts for browsing and email. What is the best-targeted intervention?
- Disk encryption
- Secure configuration baseline
- Local administrator removal
- Application allowlisting
Explanation
Correct Answer
C:Removing unnecessary local admin rights reduces attacker execution and persistence opportunities. By contrast, Application allowlisting is relevant when users can run arbitrary unsigned executables on sensitive workstations, not as a substitute for Local administrator removal in this case.
Incorrect Answers
A:Full-disk encryption protects data at rest when devices and keys are appropriately managed; that helps with the separate case where lost laptops may disclose stored customer files to someone with physical possession, not with the issue that staff routinely use high-privilege local accounts for browsing and email.
B:A controlled baseline specifies supported hardened settings and review exceptions; that helps with the separate case where new endpoints retain unnecessary services and weak default settings, not with the issue that staff routinely use high-privilege local accounts for browsing and email.
D:Allowlisting restricts execution to verified approved applications or publisher rules; that is relevant if users can run arbitrary unsigned executables on sensitive workstations, but it does not directly resolve the need arising when staff routinely use high-privilege local accounts for browsing and email.
Question 532
The CISO must resolve these three conditions: (1) workstations accept inbound connections unnecessary for their business role; (2) new endpoints retain unnecessary services and weak default settings; (3) lost laptops may disclose stored customer files to someone with physical possession. Which THREE options directly satisfy these requirements? Choose THREE.
- Host firewall policy
- Secure configuration baseline
- Application allowlisting
- Local administrator removal
- Screen lock and idle timeout
- Disk encryption
Explanation
Correct Answers
A:For the requirement that workstations accept inbound connections unnecessary for their business role, host firewall policy restricts local network exposure independently of perimeter defenses; Secure configuration baseline separately addresses the need that new endpoints retain unnecessary services and weak default settings.
B:For the requirement that new endpoints retain unnecessary services and weak default settings, a controlled baseline specifies supported hardened settings and review exceptions; Host firewall policy separately addresses the need that workstations accept inbound connections unnecessary for their business role.
F:For the requirement that lost laptops may disclose stored customer files to someone with physical possession, full-disk encryption protects data at rest when devices and keys are appropriately managed; Host firewall policy separately addresses the need that workstations accept inbound connections unnecessary for their business role.
Incorrect Answers
C:Allowlisting restricts execution to verified approved applications or publisher rules; such an effect addresses a situation where users can run arbitrary unsigned executables on sensitive workstations rather than the situation where new endpoints retain unnecessary services and weak default settings; the other need in this item is that lost laptops may disclose stored customer files to someone with physical possession.
D:Removing unnecessary local admin rights reduces attacker execution and persistence opportunities; this is pertinent when staff routinely use high-privilege local accounts for browsing and email, in contrast with the actual gap where new endpoints retain unnecessary services and weak default settings; the other need in this item is that lost laptops may disclose stored customer files to someone with physical possession.
E:Automatic locking limits casual unauthorized use of active authenticated sessions; its proper use case is one in which unattended logged-in terminals are accessible in shared office areas, not one in which new endpoints retain unnecessary services and weak default settings; the other need in this item is that lost laptops may disclose stored customer files to someone with physical possession.
Question 533
Workstations accept inbound connections unnecessary for their business role. What action would satisfy this constraint most directly?
- Local administrator removal
- Host firewall policy
- Application allowlisting
- Secure boot verification
Explanation
Correct Answer
B:Host firewall policy restricts local network exposure independently of perimeter defenses. By contrast, Local administrator removal is relevant when staff routinely use high-privilege local accounts for browsing and email, not as a substitute for Host firewall policy in this case.
Incorrect Answers
A:Removing unnecessary local admin rights reduces attacker execution and persistence opportunities; such an effect addresses a situation where staff routinely use high-privilege local accounts for browsing and email rather than the situation where workstations accept inbound connections unnecessary for their business role.
C:Allowlisting restricts execution to verified approved applications or publisher rules; the condition under which it applies is that users can run arbitrary unsigned executables on sensitive workstations, unlike the condition in the question, where workstations accept inbound connections unnecessary for their business role.
D:Verified boot chains check signed boot stages and help prevent unauthorized early execution; the condition for this measure is that malicious boot components could load before the operating system's normal defenses, whereas the current question concerns a case where workstations accept inbound connections unnecessary for their business role.
Question 534
Sensitive workstations allow unmonitored transfer to removable storage. What approach should the accountable team prioritize?
- Local administrator removal
- Host firewall policy
- Endpoint device control
- Secure boot verification
- Application allowlisting
Explanation
Correct Answer
C:Device controls constrain removable media use based on policy and business requirements. By contrast, Local administrator removal is relevant when staff routinely use high-privilege local accounts for browsing and email, not as a substitute for Endpoint device control in this case.

D:Host firewall policy restricts local network exposure independently of perimeter defenses; it helps when workstations accept inbound connections unnecessary for their business role, whereas the present requirement arises because unattended logged-in terminals are accessible in shared office areas.
Question 536
Malicious boot components could load before the operating system's normal defenses. What should the decision-maker choose?
- Secure boot verification
- Local administrator removal
- Screen lock and idle timeout
- Endpoint device control
Explanation
Correct Answer
A:Verified boot chains check signed boot stages and help prevent unauthorized early execution. By contrast, Endpoint device control is relevant when sensitive workstations allow unmonitored transfer to removable storage, not as a substitute for Secure boot verification in this case.

Question 537
A publicly traded company is reducing exposure from unpatched infrastructure. A remotely exploitable internet-facing vulnerability competes with less relevant high-score findings. What is the best-targeted intervention?
- Patch maintenance window coordination
- Vulnerability age tracking
- Patch compliance verification
- Risk-based patch triage
Explanation
Correct Answer
D:Prioritization combines exploitability, exposure, asset consequence, and compensating safeguards. By contrast, Patch maintenance window coordination is relevant when a required security update would interrupt a critical revenue service during peak operations, not as a substitute for Risk-based patch triage in this case.
Incorrect Answers
A:Coordinated windows balance urgency, business impact, readiness, and rollback capability; deploying it would matter if a required security update would interrupt a critical revenue service during peak operations, but the deciding issue here is that a remotely exploitable internet-facing vulnerability competes with less relevant high-score findings.
B:Aging metrics expose overdue treatment and prioritize escalation; that helps with the separate case where known exploitable findings remain unresolved for longer than the approved service objective, not with the issue that a remotely exploitable internet-facing vulnerability competes with less relevant high-score findings.
C:Independent verification checks installed state and reachable exposure rather than relying only on deployment reports; the condition under which it applies is that a management console reports success but vulnerable package versions remain on systems, unlike the condition in the question, where a remotely exploitable internet-facing vulnerability competes with less relevant high-score findings.
Question 538
An actively exploited vulnerability affects a business-critical authentication gateway. What should the decision-maker choose?
- Patch compliance verification
- Patch rollback plan
- Emergency patch change
- Risk-based patch triage
Explanation
Correct Answer
C:Emergency change follows accelerated authorization and testing appropriate to urgent risk. By contrast, Patch compliance verification is relevant when a management console reports success but vulnerable package versions remain on systems, not as a substitute for Emergency patch change in this case.
Incorrect Answers
A:Independent verification checks installed state and reachable exposure rather than relying only on deployment reports; this is pertinent when a management console reports success but vulnerable package versions remain on systems, in contrast with the actual gap where an actively exploited vulnerability affects a business-critical authentication gateway.
B:Rollback planning defines recovery steps, backups, testing, and authorization for a failed change; the condition under which it applies is that an update breaks an essential industrial application and teams have no restoration procedure, unlike the condition in the question, where an actively exploited vulnerability affects a business-critical authentication gateway.
D:Prioritization combines exploitability, exposure, asset consequence, and compensating safeguards; this provides its benefit when a remotely exploitable internet-facing vulnerability competes with less relevant high-score findings; the matter at hand is instead that an actively exploited vulnerability affects a business-critical authentication gateway.
Question 539
A kernel update may disrupt thousands of incompatible endpoints if deployed simultaneously. What action would satisfy this constraint most directly?
- Staged patch rollout
- Patch rollback plan
- Vulnerability age tracking
- Patch compliance verification
Explanation
Correct Answer
A:Canary and phased deployment detect adverse effects before widespread rollout. By contrast, Patch compliance verification is relevant when a management console reports success but vulnerable package versions remain on systems, not as a substitute for Staged patch rollout in this case.
Incorrect Answers
B:Rollback planning defines recovery steps, backups, testing, and authorization for a failed change; that is relevant if an update breaks an essential industrial application and teams have no restoration procedure, but it does not directly resolve the need arising when a kernel update may disrupt thousands of incompatible endpoints if deployed simultaneously.
C:Aging metrics expose overdue treatment and prioritize escalation; this is pertinent when known exploitable findings remain unresolved for longer than the approved service objective, in contrast with the actual gap where a kernel update may disrupt thousands of incompatible endpoints if deployed simultaneously.
D:Independent verification checks installed state and reachable exposure rather than relying only on deployment reports; it would be a fit if a management console reports success but vulnerable package versions remain on systems, whereas the required response must deal with the fact that a kernel update may disrupt thousands of incompatible endpoints if deployed simultaneously.
Question 540
An update breaks an essential industrial application and teams have no restoration procedure. What approach should the accountable team prioritize?
- Vulnerability age tracking
- Patch compliance verification
- Exception for unpatchable system
- Emergency patch change
- Patch rollback plan
Explanation
Correct Answer
E:Rollback planning defines recovery steps, backups, testing, and authorization for a failed change. By contrast, Vulnerability age tracking is relevant when known exploitable findings remain unresolved for longer than the approved service objective, not as a substitute for Patch rollback plan in this case.
Incorrect Answers
A:Aging metrics expose overdue treatment and prioritize escalation; that helps with the separate case where known exploitable findings remain unresolved for longer than the approved service objective, not with the issue that an update breaks an essential industrial application and teams have no restoration procedure.
B:Independent verification checks installed state and reachable exposure rather than relying only on deployment reports; the condition under which it applies is that a management console reports success but vulnerable package versions remain on systems, unlike the condition in the question, where an update breaks an essential industrial application and teams have no restoration procedure.
C:A governed exception documents isolation, monitoring, replacement, and residual risk ownership; the alternative concern is that a medical device cannot be patched without invalidating vendor support and clinical approval, but the tested need stems from the fact that an update breaks an essential industrial application and teams have no restoration procedure.
D:Emergency change follows accelerated authorization and testing appropriate to urgent risk; the alternative concern is that an actively exploited vulnerability affects a business-critical authentication gateway, but the tested need stems from the fact that an update breaks an essential industrial application and teams have no restoration procedure.
