Question 690
A contractor authenticates on a wired port but the access switch does not install the restricted RADIUS VLAN. What is the most appropriate first technical change?
- Correct the RADIUS policy precedence and group-to-role mapping
- Return a constrained guest role and apply the corresponding ACL or segment enforcement
- Align the configured shared secret and server identity on both RADIUS client and server
- Check whether the switch accepts and applies the exact VLAN/role attributes returned by RADIUS
Explanation
Correct Answer
D:A policy may decide correctly while the NAS cannot enforce the result. The discrepancy distinguishes server decision from device application.
Incorrect Answers
A:Authorization rules can select the wrong role even with valid identity. It would not resolve the documented symptom; a policy may decide correctly while the NAS cannot enforce the result.
B:Authorization defines service reachability beyond mere connection success. By contrast, a policy may decide correctly while the NAS cannot enforce the result.
C:Mismatched authentication parameters can cause request rejection or silence. In this situation, a policy may decide correctly while the NAS cannot enforce the result.
Question 691
A contractor authenticates on a wired port but the access switch does not install the restricted RADIUS VLAN. Which observation would best verify that the intended behavior is working?
- Check policy rule hits and the resulting enforced role for student and teacher test accounts
- Attempt a safe revocation test and inspect rejection logs
- Compare access-accept attributes to the effective interface VLAN and session logs
- Inspect collected DHCP/LLDP/MAC signals and the applied device role
Explanation
Correct Answer
C:The discrepancy distinguishes server decision from device application. A policy may decide correctly while the NAS cannot enforce the result.
Incorrect Answers
A:Comparing both categories identifies an overbroad match. It would not resolve the documented symptom; the discrepancy distinguishes server decision from device application.
B:A published revocation record alone does not prove the access service reads it. The relevant technical distinction is that the discrepancy distinguishes server decision from device application.
D:Inputs and outputs reveal which attribute produced the mismatch. By contrast, the discrepancy distinguishes server decision from device application.
Question 692
A contractor authenticates on a wired port but the access switch does not install the restricted RADIUS VLAN. Which belief about the configuration should the team reject?
- Give every network engineer unrestricted local super-user credentials instead of mapped roles
- Assume RADIUS Access-Accept always implies the VLAN was successfully assigned
- Increase AP transmission power to repair a wrongly authorized user role
- Change the employee's directory password and assume the device certificate is invalidated
Explanation
Correct Answer
B:Acceptance and enforcement are separate operations. A policy may decide correctly while the NAS cannot enforce the result.
Incorrect Answers
A:Shared broad access defeats least privilege and audit ownership. The relevant technical distinction is that acceptance and enforcement are separate operations.
C:RF strength does not control directory policy selection. By contrast, acceptance and enforcement are separate operations.
D:User passwords and device certificates have separate lifecycles. Here, however, acceptance and enforcement are separate operations.
Question 693
A contractor authenticates on a wired port but the access switch does not install the restricted RADIUS VLAN. What should be included in the rollout plan to limit a foreseeable failure?
- Test local VLAN existence and authorization attributes before enabling the contractor cohort
- Document device loss response, certificate rotation and offline validation limits
- Require a controlled exception with owner approval for critical devices
- Pilot the certificate migration on both new and existing laptops
Explanation
Correct Answer
A:An undefined VLAN can cause unpredictable access failures. The discrepancy distinguishes server decision from device application.
Incorrect Answers
B:Revocation must be operationally enforceable. The relevant technical distinction is that an undefined VLAN can cause unpredictable access failures.
C:Safety-sensitive endpoints deserve reliable policy governance. Here, however, an undefined VLAN can cause unpredictable access failures.
D:Old clients may have different cached trust configuration. In this situation, an undefined VLAN can cause unpredictable access failures.
Question 694
An administrator uses ClearPass to authorize network devices by profiling and suddenly misclassifies a medical monitor as a laptop. What should the network engineer do to address this requirement?
- Configure 802.1X on the switch with RADIUS and the approved role or VLAN attributes
- Review the profiling attributes and correct the policy classification using verified device inventory
- Correct the RADIUS policy precedence and group-to-role mapping
- Align identity policy and role-mapping intent across wired and wireless enforcement points
Explanation
Correct Answer
B:Profiling can be incomplete and should not override device safety requirements blindly. Inputs and outputs reveal which attribute produced the mismatch.
Incorrect Answers
A:Central identity decisions can determine the client's authorized network segment. Here, however, profiling can be incomplete and should not override device safety requirements blindly.
C:Authorization rules can select the wrong role even with valid identity. In this situation, profiling can be incomplete and should not override device safety requirements blindly.
D:The same user may otherwise get inconsistent access by transport. It would not resolve the documented symptom; profiling can be incomplete and should not override device safety requirements blindly.
Question 695
An administrator uses ClearPass to authorize network devices by profiling and suddenly misclassifies a medical monitor as a laptop. What should the team inspect to confirm the result?
- Inspect collected DHCP/LLDP/MAC signals and the applied device role
- Measure first-login time and observe RADIUS requests during primary loss
- Compare access-accept attributes to the effective interface VLAN and session logs
- Verify the registered printer is assigned print-only access and an unknown MAC is rejected
Explanation
Correct Answer
A:Inputs and outputs reveal which attribute produced the mismatch. Profiling can be incomplete and should not override device safety requirements blindly.
Incorrect Answers
B:Response-time evidence reveals excessive wait or broken fallback. It would not resolve the documented symptom; inputs and outputs reveal which attribute produced the mismatch.
C:The discrepancy distinguishes server decision from device application. In this situation, inputs and outputs reveal which attribute produced the mismatch.
D:MAC-based exceptions should not create an open guest bypass. By contrast, inputs and outputs reveal which attribute produced the mismatch.
Question 696
An administrator uses ClearPass to authorize network devices by profiling and suddenly misclassifies a medical monitor as a laptop. Which misconception is most likely to obstruct a correct fix?
- Assume a guessed device type from a MAC prefix is always sufficient for critical authorization
- Accept any MAC address from a projector vendor's OUI into the trusted role
- Disable 802.1X globally instead of correcting the RADIUS trust relationship
- Turn off TLS server-name and certificate verification on every endpoint
Explanation
Correct Answer
A:OUI heuristics can be ambiguous or stale. Profiling can be incomplete and should not override device safety requirements blindly.
Incorrect Answers
B:Vendor prefixes do not guarantee that a device is owned or approved. By contrast, oUI heuristics can be ambiguous or stale.
C:Broad bypass trades an administrative error for widespread exposure. The relevant technical distinction is that oUI heuristics can be ambiguous or stale.
D:Removing trust checks exposes users to fraudulent authentication servers. It would not resolve the documented symptom; oUI heuristics can be ambiguous or stale.
Question 697
An administrator uses ClearPass to authorize network devices by profiling and suddenly misclassifies a medical monitor as a laptop. What precaution is most important before the change is expanded?
- Document expected transport-specific exceptions and retest after policy changes
- Test local VLAN existence and authorization attributes before enabling the contractor cohort
- Stage group rule changes with explicit denied-access regression cases
- Require a controlled exception with owner approval for critical devices
Explanation
Correct Answer
D:Safety-sensitive endpoints deserve reliable policy governance. Inputs and outputs reveal which attribute produced the mismatch.
Incorrect Answers
A:Controlled differences are acceptable only when intentional. Here, however, safety-sensitive endpoints deserve reliable policy governance.
B:An undefined VLAN can cause unpredictable access failures. The relevant technical distinction is that safety-sensitive endpoints deserve reliable policy governance.
C:A broad group rule can affect every student simultaneously. By contrast, safety-sensitive endpoints deserve reliable policy governance.
Question 698
A switch supports local account login but the operations team needs centrally audited administrator permissions. Which configuration decision most directly resolves the situation?
- Align the configured shared secret and server identity on both RADIUS client and server
- Integrate supported TACACS+ or RADIUS administrator authentication with appropriate role mapping
- Align identity policy and role-mapping intent across wired and wireless enforcement points
- Configure a restricted failure-role or safe fail-closed behavior according to business policy
Explanation
Correct Answer
B:Central AAA can unify identity decisions and accountability for device administration. Login success alone does not prove command authorization.
Incorrect Answers
A:Mismatched authentication parameters can cause request rejection or silence. Here, however, central AAA can unify identity decisions and accountability for device administration.
C:The same user may otherwise get inconsistent access by transport. In this situation, central AAA can unify identity decisions and accountability for device administration.
D:Loss of central identity should not become automatic privilege escalation. The relevant technical distinction is that central AAA can unify identity decisions and accountability for device administration.
Question 699
A switch supports local account login but the operations team needs centrally audited administrator permissions. Which check most directly demonstrates the desired network behavior?
- Check policy rule hits and the resulting enforced role for student and teacher test accounts
- Inspect a permitted and denied administrator command/session along with AAA logs
- Verify the registered printer is assigned print-only access and an unknown MAC is rejected
- Check supplicant and RADIUS handshake errors against the full new chain
Explanation
Correct Answer
B:Login success alone does not prove command authorization. Central AAA can unify identity decisions and accountability for device administration.
Incorrect Answers
A:Comparing both categories identifies an overbroad match. Here, however, login success alone does not prove command authorization.
C:MAC-based exceptions should not create an open guest bypass. In this situation, login success alone does not prove command authorization.
D:Evidence pinpoints whether client or server trust is missing. It would not resolve the documented symptom; login success alone does not prove command authorization.
Question 700
A switch supports local account login but the operations team needs centrally audited administrator permissions. Which THREE steps together deliver the change, verify its effect, and reduce rollout risk? Choose THREE.
- Integrate supported TACACS+ or RADIUS administrator authentication with appropriate role mapping
- Retain secure break-glass access and monitor central AAA failures
- Test local VLAN existence and authorization attributes before enabling the contractor cohort
- Review the profiling attributes and correct the policy classification using verified device inventory
- Inspect a permitted and denied administrator command/session along with AAA logs
- Correct server priority and timeout/failover settings according to tested reachability
Explanation
Correct Answers
A:Central AAA can unify identity decisions and accountability for device administration. Login success alone does not prove command authorization.
B:An identity outage must not eliminate authorized emergency maintenance. Login success alone does not prove command authorization.
E:Login success alone does not prove command authorization. Central AAA can unify identity decisions and accountability for device administration.
Incorrect Answers
C:An undefined VLAN can cause unpredictable access failures. It would not resolve the documented symptom; an identity outage must not eliminate authorized emergency maintenance.
D:Profiling can be incomplete and should not override device safety requirements blindly. By contrast, central AAA can unify identity decisions and accountability for device administration.
F:The client must be able to use a healthy secondary when the primary is unavailable. In this situation, central AAA can unify identity decisions and accountability for device administration.
