Question 710
A corporate WLAN uses device certificates, but a lost laptop still has an unrevoked certificate. Which configuration decision most directly resolves the situation?
- Maintain an approved projector registry and require explicit registration or limited quarantine for new MAC identities
- Revoke the lost device certificate and ensure the authentication policy checks revocation
- Configure supported pre-authentication or guest/quarantine policy with a narrow onboarding service list
- Align identity policy and role-mapping intent across wired and wireless enforcement points
Explanation
Correct Answer
B:Credential removal must take effect before expiry for lost devices. A published revocation record alone does not prove the access service reads it.
Incorrect Answers
A:MAC-based access relies on accurately maintained device identity records. It would not resolve the documented symptom; credential removal must take effect before expiry for lost devices.
C:Devices can receive limited services before full identity validation without broad network access. By contrast, credential removal must take effect before expiry for lost devices.
D:The same user may otherwise get inconsistent access by transport. In this situation, credential removal must take effect before expiry for lost devices.
Question 711
A corporate WLAN uses device certificates, but a lost laptop still has an unrevoked certificate. Which check most directly demonstrates the desired network behavior?
- Measure first-login time and observe RADIUS requests during primary loss
- Verify the registered printer is assigned print-only access and an unknown MAC is rejected
- Check policy rule hits and the resulting enforced role for student and teacher test accounts
- Attempt a safe revocation test and inspect rejection logs
Explanation
Correct Answer
D:A published revocation record alone does not prove the access service reads it. Credential removal must take effect before expiry for lost devices.
Incorrect Answers
A:Response-time evidence reveals excessive wait or broken fallback. It would not resolve the documented symptom; a published revocation record alone does not prove the access service reads it.
B:MAC-based exceptions should not create an open guest bypass. By contrast, a published revocation record alone does not prove the access service reads it.
C:Comparing both categories identifies an overbroad match. The relevant technical distinction is that a published revocation record alone does not prove the access service reads it.
Question 712
A corporate WLAN uses device certificates, but a lost laptop still has an unrevoked certificate. Which assumption would be most misleading when investigating this situation?
- Increase AP transmission power to repair a wrongly authorized user role
- Change the employee's directory password and assume the device certificate is invalidated
- Assume listing two servers in configuration guarantees instant failover under every timeout
- Place unauthenticated clients directly in the full employee VLAN to simplify setup
Explanation
Correct Answer
B:User passwords and device certificates have separate lifecycles. Credential removal must take effect before expiry for lost devices.
Incorrect Answers
A:RF strength does not control directory policy selection. By contrast, user passwords and device certificates have separate lifecycles.
C:Priorities and timers influence actual behavior. The relevant technical distinction is that user passwords and device certificates have separate lifecycles.
D:An onboarding exception must not confer employee authorization. Here, however, user passwords and device certificates have separate lifecycles.
Question 713
A corporate WLAN uses device certificates, but a lost laptop still has an unrevoked certificate. Which safeguard best reduces the deployment risk in this case?
- Retain secure break-glass access and monitor central AAA failures
- Stage group rule changes with explicit denied-access regression cases
- Test local VLAN existence and authorization attributes before enabling the contractor cohort
- Document device loss response, certificate rotation and offline validation limits
Explanation
Correct Answer
D:Revocation must be operationally enforceable. A published revocation record alone does not prove the access service reads it.
Incorrect Answers
A:An identity outage must not eliminate authorized emergency maintenance. In this situation, revocation must be operationally enforceable.
B:A broad group rule can affect every student simultaneously. Here, however, revocation must be operationally enforceable.
C:An undefined VLAN can cause unpredictable access failures. The relevant technical distinction is that revocation must be operationally enforceable.
Question 714
A student signs in successfully but gets a role allowing teacher-only applications after a directory group restructure. What is the most appropriate first technical change?
- Correct the RADIUS policy precedence and group-to-role mapping
- Check whether the switch accepts and applies the exact VLAN/role attributes returned by RADIUS
- Return a constrained guest role and apply the corresponding ACL or segment enforcement
- Configure 802.1X on the switch with RADIUS and the approved role or VLAN attributes
Explanation
Correct Answer
A:Authorization rules can select the wrong role even with valid identity. Comparing both categories identifies an overbroad match.
Incorrect Answers
B:A policy may decide correctly while the NAS cannot enforce the result. It would not resolve the documented symptom; authorization rules can select the wrong role even with valid identity.
C:Authorization defines service reachability beyond mere connection success. In this situation, authorization rules can select the wrong role even with valid identity.
D:Central identity decisions can determine the client's authorized network segment. Here, however, authorization rules can select the wrong role even with valid identity.
Question 715
A student signs in successfully but gets a role allowing teacher-only applications after a directory group restructure. Which observation would best verify that the intended behavior is working?
- Compare access-accept attributes to the effective interface VLAN and session logs
- Inspect a permitted and denied administrator command/session along with AAA logs
- Check policy rule hits and the resulting enforced role for student and teacher test accounts
- Measure first-login time and observe RADIUS requests during primary loss
Explanation
Correct Answer
C:Comparing both categories identifies an overbroad match. Authorization rules can select the wrong role even with valid identity.
Incorrect Answers
A:The discrepancy distinguishes server decision from device application. It would not resolve the documented symptom; comparing both categories identifies an overbroad match.
B:Login success alone does not prove command authorization. By contrast, comparing both categories identifies an overbroad match.
D:Response-time evidence reveals excessive wait or broken fallback. In this situation, comparing both categories identifies an overbroad match.
Question 716
A student signs in successfully but gets a role allowing teacher-only applications after a directory group restructure. Which belief about the configuration should the team reject?
- Change the employee's directory password and assume the device certificate is invalidated
- Map guest identities to the staff role because they both use a RADIUS server
- Assume RADIUS Access-Accept always implies the VLAN was successfully assigned
- Increase AP transmission power to repair a wrongly authorized user role
Explanation
Correct Answer
D:RF strength does not control directory policy selection. Authorization rules can select the wrong role even with valid identity.
Incorrect Answers
A:User passwords and device certificates have separate lifecycles. By contrast, rF strength does not control directory policy selection.
B:Shared authentication infrastructure does not imply shared access rights. The relevant technical distinction is that rF strength does not control directory policy selection.
C:Acceptance and enforcement are separate operations. It would not resolve the documented symptom; rF strength does not control directory policy selection.
Question 717
A student signs in successfully but gets a role allowing teacher-only applications after a directory group restructure. Which TWO actions together implement the required change and verify that it works? Choose TWO.
- Use a supported reauthentication or change-of-authorization process with policy validation
- Check policy rule hits and the resulting enforced role for student and teacher test accounts
- Correct the RADIUS policy precedence and group-to-role mapping
- Update the trusted certificate-chain policy and distribute the intended intermediate/root certificates
- Document expected transport-specific exceptions and retest after policy changes
Explanation
Correct Answers
B:Comparing both categories identifies an overbroad match. Authorization rules can select the wrong role even with valid identity.
C:Authorization rules can select the wrong role even with valid identity. Comparing both categories identifies an overbroad match.
Incorrect Answers
A:Authorization changes may require an explicit session update to take effect. Here, however, authorization rules can select the wrong role even with valid identity.
D:EAP-TLS trust requires compatible certificate issuers and approved names. By contrast, authorization rules can select the wrong role even with valid identity.
E:Controlled differences are acceptable only when intentional. The relevant technical distinction is that a broad group rule can affect every student simultaneously.
Question 718
An enterprise uses MAC authentication for classroom projectors and wants to detect unregistered replacements. What should the network engineer do to address this requirement?
- Revoke the lost device certificate and ensure the authentication policy checks revocation
- Configure 802.1X on the switch with RADIUS and the approved role or VLAN attributes
- Use MAC authentication bypass with a restricted printer role where supported
- Maintain an approved projector registry and require explicit registration or limited quarantine for new MAC identities
Explanation
Correct Answer
D:MAC-based access relies on accurately maintained device identity records. The comparison confirms the inventory boundary actually controls access.
Incorrect Answers
A:Credential removal must take effect before expiry for lost devices. Here, however, mAC-based access relies on accurately maintained device identity records.
B:Central identity decisions can determine the client's authorized network segment. In this situation, mAC-based access relies on accurately maintained device identity records.
C:Non-802.1X devices still require an accountable limited access decision. The relevant technical distinction is that mAC-based access relies on accurately maintained device identity records.
Question 719
An enterprise uses MAC authentication for classroom projectors and wants to detect unregistered replacements. What should the team inspect to confirm the result?
- Probe DNS and an employee-record destination from a test guest identity
- Connect an enrolled and an unknown projector and inspect the resulting port session roles
- Check policy rule hits and the resulting enforced role for student and teacher test accounts
- Measure first-login time and observe RADIUS requests during primary loss
Explanation
Correct Answer
B:The comparison confirms the inventory boundary actually controls access. MAC-based access relies on accurately maintained device identity records.
Incorrect Answers
A:Both an allowed and denied test are needed to prove policy. In this situation, the comparison confirms the inventory boundary actually controls access.
C:Comparing both categories identifies an overbroad match. It would not resolve the documented symptom; the comparison confirms the inventory boundary actually controls access.
D:Response-time evidence reveals excessive wait or broken fallback. Here, however, the comparison confirms the inventory boundary actually controls access.
Question 720
An enterprise uses MAC authentication for classroom projectors and wants to detect unregistered replacements. Which misconception is most likely to obstruct a correct fix?
- Treat every AAA timeout as explicit authorization to the most trusted subnet
- Accept any MAC address from a projector vendor's OUI into the trusted role
- Assume identical username text always produces an identical role without policy configuration
- Increase AP transmission power to repair a wrongly authorized user role
Explanation
Correct Answer
B:Vendor prefixes do not guarantee that a device is owned or approved. MAC-based access relies on accurately maintained device identity records.
Incorrect Answers
A:Authentication failure is not a proof of user identity. In this situation, vendor prefixes do not guarantee that a device is owned or approved.
C:Service type and NAS attributes can affect authorization rules. It would not resolve the documented symptom; vendor prefixes do not guarantee that a device is owned or approved.
D:RF strength does not control directory policy selection. By contrast, vendor prefixes do not guarantee that a device is owned or approved.
