Question 1090

At Seabright Municipal Works, a team reports that it corrected the following problem affecting public service networks and records: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. Which observation BEST verifies that the correction actually worked?

  1. A spoofed unknown endpoint cannot obtain privileged user-network resources.
  2. Valid employees receive enterprise access and failed or guest sessions receive only restricted access.
  3. 802.1X requests reach the new ISE node and successful authentications are logged.
  4. The laptop receives its assigned VLAN and the policy hit is visible in ISE logs.

Explanation

Correct Answer

B:

Valid employees receive enterprise access and failed or guest sessions receive only restricted access. This is the decisive evidence for the original problem: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. It verifies that the intended corrective control—Correct authentication method ordering and authorization fallback conditions—works in the relevant environment; a completed change ticket alone would not prove the outcome at Seabright Municipal Works.

Incorrect Answers

A:

A spoofed unknown endpoint cannot obtain privileged user-network resources. This would be relevant evidence for a different failure: An access policy grants privileged access based only on a claimed device MAC address, usually addressed by Combine MAB with profiling, segmentation, and stronger identity controls where possible. It does not demonstrate that the current problem at Seabright Municipal Works was resolved. The specific required evidence is: Valid employees receive enterprise access and failed or guest sessions receive only restricted access.

C:

802.1X requests reach the new ISE node and successful authentications are logged. This would be relevant evidence for a different failure: The switch sends RADIUS to an old ISE address and all port authentication times out after a server migration, usually addressed by Update the network device AAA server configuration and confirm reachability and shared secret. It does not demonstrate that the current problem at Seabright Municipal Works was resolved. The specific required evidence is: Valid employees receive enterprise access and failed or guest sessions receive only restricted access.

D:

The laptop receives its assigned VLAN and the policy hit is visible in ISE logs. This would be relevant evidence for a different failure: An 802.1X laptop authenticates successfully but receives the wrong VLAN due to an authorization profile mismatch, usually addressed by Inspect ISE policy set conditions and the RADIUS authorization result delivered to the switch. It does not demonstrate that the current problem at Seabright Municipal Works was resolved. The specific required evidence is: Valid employees receive enterprise access and failed or guest sessions receive only restricted access.

Question 1091

A security engineer at Frostline Distribution reviews warehouse and transport operations as part of a security incident tabletop exercise. The observed problem is: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. What is the BEST corrective action?

  1. Correct authentication method ordering and authorization fallback conditions.
  2. Configure closed or appropriately restricted authentication behavior with an explicit fallback design.
  3. Combine MAB with profiling, segmentation, and stronger identity controls where possible.
  4. Use Cisco ISE MAC Authentication Bypass with constrained authorization and device profiling.

Explanation

Correct Answer

A:

Correct authentication method ordering and authorization fallback conditions. This directly addresses the documented failure: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. For the Frostline Distribution environment, the measurable success condition is: Valid employees receive enterprise access and failed or guest sessions receive only restricted access. This control targets the specific failure rather than merely changing an unrelated security setting.

Incorrect Answers

B:

Configure closed or appropriately restricted authentication behavior with an explicit fallback design. That action fits another problem: An access switch port allows unauthenticated clients onto a production VLAN when 802.1X fails. It does not directly remediate the current finding at Frostline Distribution: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. The relevant corrective control for this case is: Correct authentication method ordering and authorization fallback conditions.

C:

Combine MAB with profiling, segmentation, and stronger identity controls where possible. That action fits another problem: An access policy grants privileged access based only on a claimed device MAC address. It does not directly remediate the current finding at Frostline Distribution: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. The relevant corrective control for this case is: Correct authentication method ordering and authorization fallback conditions.

D:

Use Cisco ISE MAC Authentication Bypass with constrained authorization and device profiling. That action fits another problem: A printer lacks an 802.1X supplicant but must join a restricted service network. It does not directly remediate the current finding at Frostline Distribution: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. The relevant corrective control for this case is: Correct authentication method ordering and authorization fallback conditions.

Question 1092

During a security incident tabletop exercise at Frostline Distribution, engineers say that they resolved this finding: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. Which result provides the STRONGEST acceptance evidence?

  1. A spoofed unknown endpoint cannot obtain privileged user-network resources.
  2. The known printer reaches only its required service while unknown MAC addresses remain restricted.
  3. An unauthorized test device cannot enter the production VLAN after authentication failure.
  4. Valid employees receive enterprise access and failed or guest sessions receive only restricted access.

Explanation

Correct Answer

D:

Valid employees receive enterprise access and failed or guest sessions receive only restricted access. This is the decisive evidence for the original problem: An organization has separate employee and guest policies but the switch incorrectly falls back to guest VLAN for every failed login. It verifies that the intended corrective control—Correct authentication method ordering and authorization fallback conditions—works in the relevant environment; a completed change ticket alone would not prove the outcome at Frostline Distribution.

Question 1093

At Boreal Foods, during a cross-team security policy review, the security team is examining supplier systems and production operations. The finding is: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. Which action BEST addresses this specific security issue?

  1. Apply session expiration with CoA or another supported active session update.
  2. Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy.
  3. Verify device CoA support, source, shared secret, and permitted UDP exchange.
  4. Record network access device identity, user or endpoint, session identifiers, and authorization result.

Explanation

Correct Answer

B:

Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy. This directly addresses the documented failure: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. For the Boreal Foods environment, the measurable success condition is: The active session changes authorization promptly without waiting for a user reconnection. This control targets the specific failure rather than merely changing an unrelated security setting.

Incorrect Answers

A:

Apply session expiration with CoA or another supported active session update. That action fits another problem: A guest account expires but an existing session remains active because authorization is evaluated only on connection. It does not directly remediate the current finding at Boreal Foods: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. The relevant corrective control for this case is: Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy.

C:

Verify device CoA support, source, shared secret, and permitted UDP exchange. That action fits another problem: An ISE CoA request is sent but the switch ignores it because the configured RADIUS dynamic authorization settings are incorrect. It does not directly remediate the current finding at Boreal Foods: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. The relevant corrective control for this case is: Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy.

D:

Record network access device identity, user or endpoint, session identifiers, and authorization result. That action fits another problem: CoA events occur but analysts cannot correlate which switch session received the updated policy. It does not directly remediate the current finding at Boreal Foods: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. The relevant corrective control for this case is: Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy.

Question 1094

At Boreal Foods, a team reports that it corrected the following problem affecting supplier systems and production operations: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. Which observation BEST verifies that the correction actually worked?

  1. The expired guest loses network access at the policy deadline.
  2. The network access device acknowledges CoA and updates the targeted session.
  3. Audit logs link the original authentication, CoA request, and final session state.
  4. The active session changes authorization promptly without waiting for a user reconnection.

Explanation

Correct Answer

D:

The active session changes authorization promptly without waiting for a user reconnection. This is the decisive evidence for the original problem: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. It verifies that the intended corrective control—Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy—works in the relevant environment; a completed change ticket alone would not prove the outcome at Boreal Foods.

Question 1095

A security engineer at Horizon Energy Services reviews remote workforce and operational IT as part of a planned service expansion. The observed problem is: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. What is the BEST corrective action?

  1. Verify device CoA support, source, shared secret, and permitted UDP exchange.
  2. Trigger appropriate CoA reauthentication or authorization update for the specific live session.
  3. Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy.
  4. Scope dynamic authorization to the intended session identifiers and supported operation.

Explanation

Correct Answer

C:

Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy. This directly addresses the documented failure: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. For the Horizon Energy Services environment, the measurable success condition is: The active session changes authorization promptly without waiting for a user reconnection.

The relevant corrective control for this case is: Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy.

B:

Trigger appropriate CoA reauthentication or authorization update for the specific live session. That action fits another problem: A user is moved to a new security group in ISE while an existing session keeps old permissions. It does not directly remediate the current finding at Horizon Energy Services: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. The relevant corrective control for this case is: Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy.

D:

Scope dynamic authorization to the intended session identifiers and supported operation. That action fits another problem: CoA policy mistakenly terminates all port sessions during a single device compliance change. It does not directly remediate the current finding at Horizon Energy Services: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. The relevant corrective control for this case is: Use a valid RADIUS Change of Authorization to re-evaluate and apply the restricted session policy.

Question 1096

During a planned service expansion at Horizon Energy Services, engineers say that they resolved this finding: An endpoint becomes noncompliant after authentication but retains the originally assigned network role. Which result provides the STRONGEST acceptance evidence?

  1. The user's effective network policy changes and the event is traceable to ISE.
  2. Only the noncompliant endpoint's session changes; unrelated clients remain online.
  3. The active session changes authorization promptly without waiting for a user reconnection.
  4. The network access device acknowledges CoA and updates the targeted session.
