Question 740

A guest web portal redirects successfully but browsers report that its TLS certificate does not match the portal hostname. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Maintain accurate endpoint inventories and exception approvals.
  2. Plan certificate renewals and DNS name changes together.
  3. Make authorization policy and periodic recertification part of onboarding.
  4. Treat weak device attributes as supporting signals, not sole authorization evidence.

Explanation

Correct Answer

B:

This is a continuing control for the failure mode in which the certificate identity check fails before users can safely trust the HTTPS portal. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

A:

That control is useful for a different failure, such as when an access switch detects unauthorized MAC addresses but the operator plans to disable all port controls to restore a single legitimate printer. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when a switch administrator attempts to apply a full-access policy to every authenticated wired client to simplify ticket handling. It would leave the present failure mode insufficiently addressed.

D:

That control is useful for a different failure, such as when a printer is allowed into a protected VLAN solely because its hostname matches an approved naming prefix. It would leave the present failure mode insufficiently addressed.

Question 741

A wireless team enables WPA3-Enterprise on a protected SSID, but users are allowed to ignore certificate-validation failures in their supplicant profiles. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Enforce supplicant configuration policies instead of user-click-through trust.
  2. Maintain accurate endpoint inventories and exception approvals.
  3. Test IoT lateral and management-plane restrictions with every new device class.
  4. Enforce secure provisioning checks before connecting devices to production.

Explanation

Correct Answer

A:

This is a continuing control for the failure mode in which strong WLAN encryption does not prevent credential leakage to a rogue RADIUS server when clients ignore server certificates. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

B:

That control is useful for a different failure, such as when an access switch detects unauthorized MAC addresses but the operator plans to disable all port controls to restore a single legitimate printer. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when an IoT camera VLAN receives full access to network management interfaces because the firewall default rule is permissive. It would leave the present failure mode insufficiently addressed.

D:

That control is useful for a different failure, such as when an employee access switch accepts default administrative passwords from a factory deployment image. It would leave the present failure mode insufficiently addressed.

Question 742

A campus switch uses a production network as its management source without restricting who can initiate SSH sessions. Which ongoing operational safeguard best reduces the chance of recurrence?

  2. Plan certificate renewals and DNS name changes together.
  3. Review old permit rules when network trust boundaries change.
  4. Include SSH-only and management isolation rules in secure device templates.

Explanation

Correct Answer

A:

This is a continuing control for the failure mode in which management exposure to ordinary client segments increases the risk of unauthorized administrative access. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

B:

That control is useful for a different failure, such as when a guest web portal redirects successfully but browsers report that its TLS certificate does not match the portal hostname. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when a branch firewall permits internal IoT devices to initiate sessions to the NAC administration console by a legacy broad access rule. It would leave the present failure mode insufficiently addressed.

A printer is allowed into a protected VLAN solely because its hostname matches an approved naming prefix. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Review AAA protocol protection and transport trust at new sites.
  2. Treat weak device attributes as supporting signals, not sole authorization evidence.
  3. Include SSH-only and management isolation rules in secure device templates.
  4. Review certificate or identity lifecycle and per-user revocation processes.

Explanation

Correct Answer

B:

This is a continuing control for the failure mode in which hostnames are user-changeable labels and do not establish trustworthy device ownership. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

A:

That control is useful for a different failure, such as when a campus uses an unencrypted RADIUS configuration across a transport network where message content protection is mandated. It would leave the present failure mode insufficiently addressed.

C:

Question 747

Staff Wi-Fi clients have correct certificates but the RADIUS server cannot see authentication requests after a network ACL update. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Test AAA transport reachability after security policy changes.
  2. Separate authentication from authorization in incident workflows.
  3. Review identity group and attribute mappings after directory restructuring.
  4. Test revocation and session lifetime policy during certificate rotations.

Explanation

Correct Answer

A:

This is a continuing control for the failure mode in which a network access rule blocks the AAA request or response path before credential validation occurs. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

B:

That control is useful for a different failure, such as when a switch shows an EAP failure but engineers alter the user's VLAN before confirming whether the supplicant completed authentication. It would leave the present failure mode insufficiently addressed.

C:

That control is useful for a different failure, such as when a contractor is in the approved directory group but receives employee network privileges because role mapping ignores the account's contractor attribute. It would leave the present failure mode insufficiently addressed.

Question 748

An access switch performs 802.1X on user ports, but unauthenticated clients are placed into production VLAN by an incorrect fallback policy. Which ongoing operational safeguard best reduces the chance of recurrence?

  1. Include failed-authentication cases in every switch template acceptance test.
  2. Expire approved MAC entries and validate profiling evidence periodically.
  3. Review sponsor approval and guest account lifecycle integrations.
  4. Rehearse AAA failure modes and store outage policy signoffs.

Explanation

Correct Answer

A:

This is a continuing control for the failure mode in which the current fallback grants production access even without successful identity validation. It complements the immediate fix instead of relying on a one-off correction.

Incorrect Answers

B:

That control is useful for a different failure, such as when a lab's headless sensors cannot run an 802.1X supplicant, and technicians propose allowing every unknown MAC to bypass access control. It would leave the present failure mode insufficiently addressed.

C:
