Question 300

An access interface has IBNS 2.0 policy events in an order that traps endpoints in an unauthenticated session. The observed failure is: Incorrect event ordering can bypass desired methods or prevent legitimate endpoints from authenticating. Which remediation resolves the underlying fault while maintaining policy?

  1. The supported recovery is to use only the RADIUS server GUI to change every switch control-policy event.
  2. The supported recovery is to assume IBNS control policy is equivalent to a named VLAN description.
  3. The supported recovery is to enable unconditional success on all failed EAP attempts.
  4. The supported recovery is to correct event policy and validate timed EAP retries and authorized fallback for representative endpoints.

Explanation

Correct Answer

D:

IBNS 2.0 policy maps drive access-session behavior based on relevant authentication events. For the specific situation, an access interface has IBNS 2.0 policy events in an order that traps endpoints in an unauthenticated session.

Incorrect Answers

A:

Use only the RADIUS server GUI to change every switch control-policy event. This action does not repair the identified failure. Incorrect event ordering can bypass desired methods or prevent legitimate endpoints from authenticating. Instead, correct event policy and validate timed EAP retries and authorized fallback for representative endpoints. For the specific situation, an access interface has IBNS 2.0 policy events in an order that traps endpoints in an unauthenticated session.

B:

Assume IBNS control policy is equivalent to a named VLAN description. This action does not repair the identified failure. Incorrect event ordering can bypass desired methods or prevent legitimate endpoints from authenticating. Instead, correct event policy and validate timed EAP retries and authorized fallback for representative endpoints. For the specific situation, an access interface has IBNS 2.0 policy events in an order that traps endpoints in an unauthenticated session.

C:

Enable unconditional success on all failed EAP attempts. This action does not repair the identified failure. Incorrect event ordering can bypass desired methods or prevent legitimate endpoints from authenticating. Instead, correct event policy and validate timed EAP retries and authorized fallback for representative endpoints. For the specific situation, an access interface has IBNS 2.0 policy events in an order that traps endpoints in an unauthenticated session.

Question 301

An IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode. Which administrator action is appropriate for this ISE access-control problem?

  1. Use multi-host unconditional authorization as a substitute for per-device security.
  2. Assume every port automatically distinguishes phone and desktop with no host-mode settings.
  3. Select supported multi-domain or multi-auth host mode matched to phone and data device behavior and security policy.
  4. Add the phone to an AD group and claim the switch host mode changed.

Explanation

Correct Answer

C:

Verify the effect through switch host mode, learned MACs, voice and data sessions, authentication outcomes and VLAN application.

Incorrect Answers

A:

This does not implement the required control for Host modes for phone and PC on one port.

B:

That option would assume every port automatically distinguishes phone and desktop with no host-mode settings, but it addresses a different concern. Verify the effect through switch host mode, learned MACs, voice and data sessions, authentication outcomes and VLAN application.

D:

Using single-host where multiple identities are required can force a device off the port or apply incorrect policy. For the specific situation, an IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode.

Question 302

An IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode. Which collected records establish that the ISE decision actually took effect?

  1. A switch interface description without any live AAA request or response.
  2. An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
  3. Switch host mode, learned MACs, voice and data sessions, authentication outcomes and VLAN application.
  4. A current login screenshot from a completely unrelated ISE deployment.

Explanation

Correct Answer

C:

These observations directly establish the result of Host modes for phone and PC on one port for the described endpoint or network device. For the specific situation, an IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode.

Incorrect Answers

A:

This observation cannot verify Host modes for phone and PC on one port. For the specific situation, an IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode.

B:

This observation cannot verify Host modes for phone and PC on one port. Check switch host mode, learned MACs, voice and data sessions, authentication outcomes and VLAN application.

D:

This observation cannot verify Host modes for phone and PC on one port. Host-mode choice defines how multiple endpoint identities share an authenticated interface.

Question 303

An IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode. Which statement about the relevant technology is correct?

  1. A captive portal page automatically changes network authorization on every active NAD session without signaling.
  2. Host-mode choice defines how multiple endpoint identities share an authenticated interface.
  3. A successful switch port link signal always proves the device identity and policy were verified.
  4. Every RADIUS Access-Accept grants unrestricted access to all applications.

Explanation

Correct Answer

B:

This is the governing technical behavior for Host modes for phone and PC on one port. For the specific situation, an IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode.

Incorrect Answers

A:

A captive portal page automatically changes network authorization on every active NAD session without signaling. This generalization is not valid for Host modes for phone and PC on one port. Instead host-mode choice defines how multiple endpoint identities share an authenticated interface.

Question 304

An IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode. An operator proposes the following incorrect shortcut: Use multi-host unconditional authorization as a substitute for per-device security. What specific security or operational failure should be anticipated?

  1. Reading the authentication event report caused the original network access outage.
  2. The only result is an unrelated portal background color change.
  3. Using single-host where multiple identities are required can force a device off the port or apply incorrect policy.
  4. Accurate device accounting automatically created every earlier failed EAP exchange.

Explanation

Correct Answer

C:

The shortcut is unsuitable because host-mode choice defines how multiple endpoint identities share an authenticated interface. For the specific situation, an IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode.

Incorrect Answers

A:

This unrelated assertion does not explain the Host modes for phone and PC on one port problem. The relevant risk is that using single-host where multiple identities are required can force a device off the port or apply incorrect policy.

B:

This unrelated assertion does not explain the Host modes for phone and PC on one port problem. For the specific situation, an IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode.

D:

This unrelated assertion does not explain the Host modes for phone and PC on one port problem. Check switch host mode, learned MACs, voice and data sessions, authentication outcomes and VLAN application.

Question 305

An IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode. The observed failure is: Using single-host where multiple identities are required can force a device off the port or apply incorrect policy. Which remediation resolves the underlying fault while maintaining policy?

  1. Assume every port automatically distinguishes phone and desktop with no host-mode settings.
  2. Add the phone to an AD group and claim the switch host mode changed.
  3. Correct host mode and test the phone plus workstation with independently expected policies.
  4. Use multi-host unconditional authorization as a substitute for per-device security.

Explanation

Correct Answer

C:

This restores the intended operational behavior for Host modes for phone and PC on one port. For the specific situation, an IP phone and workstation share an access switch port but only one MAC is permitted by its current authentication host mode.

Incorrect Answers

A:

That option would assume every port automatically distinguishes phone and desktop with no host-mode settings, but it addresses a different concern. This restores the intended operational behavior for Host modes for phone and PC on one port.

B:

That option would add the phone to an AD group and claim the switch host mode changed, but it addresses a different concern. This restores the intended operational behavior for Host modes for phone and PC on one port.

D:
