Question 40

A global enterprise wants separate authentication capacity near access devices and centralized administration. The observed failure is: An untested one-node design can lose all authentication decisions when that appliance fails. Which controlled recovery BEST restores the intended state?

  1. The supported recovery is to use an external DNS alias as the sole replacement for policy node redundancy.
  2. The supported recovery is to assume a single standalone VM provides multi-site fault tolerance automatically.
  3. The supported recovery is to deploy eligible redundant PSNs and verify connectivity and availability against the actual business target.
  4. The supported recovery is to put PSNs only behind an untested high-latency path regardless of failure modes.

Explanation

Correct Answer

C:

This restores the intended operational behavior for Standalone versus distributed ISE design. For the specific situation, a global enterprise wants separate authentication capacity near access devices and centralized administration.

Incorrect Answers

A:

Use an external DNS alias as the sole replacement for policy node redundancy. This action does not repair the identified failure. An untested one-node design can lose all authentication decisions when that appliance fails. Instead, deploy eligible redundant PSNs and verify connectivity and availability against the actual business target. For the specific situation, a global enterprise wants separate authentication capacity near access devices and centralized administration.

B:

Assume a single standalone VM provides multi-site fault tolerance automatically. This action does not repair the identified failure. An untested one-node design can lose all authentication decisions when that appliance fails. Instead, deploy eligible redundant PSNs and verify connectivity and availability against the actual business target. For the specific situation, a global enterprise wants separate authentication capacity near access devices and centralized administration.

D:

Put PSNs only behind an untested high-latency path regardless of failure modes. This action does not repair the identified failure. An untested one-node design can lose all authentication decisions when that appliance fails. Instead, deploy eligible redundant PSNs and verify connectivity and availability against the actual business target. For the specific situation, a global enterprise wants separate authentication capacity near access devices and centralized administration.

Question 41

A site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance. What is the BEST supported ISE implementation or corrective action?

  1. Assume adding a PSN automatically edits every switch AAA configuration.
  2. Configure primary and secondary reachable RADIUS servers and test client retry or failover behavior with consistent ISE policy.
  3. Set all network devices to use the same failed single destination.
  4. Disable RADIUS timeouts instead of configuring an alternate server.

Explanation

Correct Answer

B:

Access-device RADIUS high availability depends on the NAD server list and working policy service endpoints. For the specific situation, a site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance.

Incorrect Answers

A:

This does not implement the required control for Multi-site Policy Service Node availability. Redundant PSNs do not improve uptime when the access device never targets the backup.

C:

That option would set all network devices to use the same failed single destination, but it addresses a different concern. Access-device RADIUS high availability depends on the NAD server list and working policy service endpoints.

D:

Redundant PSNs do not improve uptime when the access device never targets the backup. For the specific situation, a site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance.

Question 42

A site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance. Which evidence BEST verifies the intended operational outcome?

  1. A successful ICMP echo that does not test the required identity-service workflow.
  2. A browser theme label without a current authorization trace.
  3. NAD server group, timeout and retry values, PSN health, network route and successful failover events.
  4. An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.

Explanation

Correct Answer

C:

Access-device RADIUS high availability depends on the NAD server list and working policy service endpoints. These observations directly establish the result of Multi-site Policy Service Node availability for the described endpoint or network device.

Incorrect Answers

A:

This observation cannot verify Multi-site Policy Service Node availability. Access-device RADIUS high availability depends on the NAD server list and working policy service endpoints.

B:

This observation cannot verify Multi-site Policy Service Node availability. For the specific situation, a site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance.

D:

This observation cannot verify Multi-site Policy Service Node availability. Check nAD server group, timeout and retry values, PSN health, network route and successful failover events.

Question 43

A site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance. Which technical principle BEST explains the required decision?

  1. All Cisco ISE administration and policy personas perform exactly the same service.
  2. Access-device RADIUS high availability depends on the NAD server list and working policy service endpoints.
  3. A captive portal page automatically changes network authorization on every active NAD session without signaling.
  4. A MAC address is a cryptographic proof of endpoint device ownership.

Explanation

Correct Answer

B:

The supported implementation is to configure primary and secondary reachable RADIUS servers and test client retry or failover behavior with consistent ISE policy. For the specific situation, a site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance.

Incorrect Answers

A:

This generalization is not valid for Multi-site Policy Service Node availability. Instead access-device RADIUS high availability depends on the NAD server list and working policy service endpoints.

C:

This generalization is not valid for Multi-site Policy Service Node availability. For the specific situation, a site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance.

D:

This generalization is not valid for Multi-site Policy Service Node availability. Verify the actual state using nAD server group, timeout and retry values, PSN health, network route and successful failover events.

Question 44

A site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance. An operator proposes the following incorrect shortcut: Assume adding a PSN automatically edits every switch AAA configuration. What material risk or failure follows from that shortcut?

  1. Accurate device accounting automatically created every earlier failed EAP exchange.
  2. Redundant PSNs do not improve uptime when the access device never targets the backup.
  3. Inspecting a correct endpoint certificate generated the original directory outage.
  4. A justified least-privilege ACL caused every unrelated network authentication fault.

Explanation

Correct Answer

B:

The shortcut is unsuitable because access-device RADIUS high availability depends on the NAD server list and working policy service endpoints. For the specific situation, a site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance.

Incorrect Answers

A:

This unrelated assertion does not explain the Multi-site Policy Service Node availability problem. The relevant risk is that redundant PSNs do not improve uptime when the access device never targets the backup.

C:

This unrelated assertion does not explain the Multi-site Policy Service Node availability problem. For the specific situation, a site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance.

D:

This unrelated assertion does not explain the Multi-site Policy Service Node availability problem. Check nAD server group, timeout and retry values, PSN health, network route and successful failover events.

Question 45

A site has two PSNs but network devices only define one RADIUS host and authentication stops during maintenance. The observed failure is: Redundant PSNs do not improve uptime when the access device never targets the backup. Which controlled recovery BEST restores the intended state?

  1. Correct NAD AAA server definitions and verify authentication during controlled PSN loss.
  2. Set all network devices to use the same failed single destination.
  3. Disable RADIUS timeouts instead of configuring an alternate server.
  4. Assume adding a PSN automatically edits every switch AAA configuration.

Explanation

Question 46

A wireless controller sends all authorization to a distant PSN even though a healthy local policy node exists. Which configuration decision most directly satisfies the requirement?

  1. In this case, configure primary and secondary reachable RADIUS servers and test client retry or failover behavior with consistent ISE policy.
  2. In this case, set all network devices to use the same failed single destination.
  3. In this case, disable RADIUS timeouts instead of configuring an alternate server.
  4. In this case, assume adding a PSN automatically edits every switch AAA configuration.

Explanation

Correct Answer

A:

Access-device RADIUS high availability depends on the NAD server list and working policy service endpoints. For the specific situation, a wireless controller sends all authorization to a distant PSN even though a healthy local policy node exists.

Incorrect Answers

B:

Set all network devices to use the same failed single destination. This alternative overlooks a required prerequisite or targets the wrong function. Access-device RADIUS high availability depends on the NAD server list and working policy service endpoints. The relevant evidence is nAD server group, timeout and retry values, PSN health, network route and successful failover events. For the specific situation, a wireless controller sends all authorization to a distant PSN even though a healthy local policy node exists.

C:

Redundant PSNs do not improve uptime when the access device never targets the backup. Instead the intended policy action is configure primary and secondary reachable RADIUS servers and test client retry or failover behavior with consistent ISE policy.

D:

This does not implement the required control for Multi-site Policy Service Node availability. Use the supported approach: configure primary and secondary reachable RADIUS servers and test client retry or failover behavior with consistent ISE policy.

Question 47

A wireless controller sends all authorization to a distant PSN even though a healthy local policy node exists. What observations most directly test this network-access condition?

  1. The supporting evidence is nAD server group, timeout and retry values, PSN health, network route and successful failover events.
  2. The supporting evidence is a device hostname alone without the policy result or authenticated source.
  3. The supporting evidence is a successful ICMP echo that does not test the required identity-service workflow.
  4. The supporting evidence is a browser theme label without a current authorization trace.

Explanation

Correct Answer

A:

Access-device RADIUS high availability depends on the NAD server list and working policy service endpoints. NAD server group, timeout and retry values, PSN health, network route and successful failover events.

Incorrect Answers

B:

This observation cannot verify Multi-site Policy Service Node availability. A device hostname alone without the policy result or authenticated source.

C:

This observation cannot verify Multi-site Policy Service Node availability. A successful ICMP echo that does not test the required identity-service workflow.

D:

This observation cannot verify Multi-site Policy Service Node availability. A browser theme label without a current authorization trace.

Question 48

A wireless controller sends all authorization to a distant PSN even though a healthy local policy node exists. What principle of ISE authentication and authorization explains this case?

  1. The governing principle is that a MAC address is a cryptographic proof of endpoint device ownership.
  2. The governing principle is that access-device RADIUS high availability depends on the NAD server list and working policy service endpoints.
  3. The governing principle is that all Cisco ISE administration and policy personas perform exactly the same service.
  4. The governing principle is that a policy display name alone is the complete source of enforcement state.

Explanation

Correct Answer

B:

The supported implementation is to configure primary and secondary reachable RADIUS servers and test client retry or failover behavior with consistent ISE policy. For the specific situation, a wireless controller sends all authorization to a distant PSN even though a healthy local policy node exists.

Incorrect Answers

A:

This generalization is not valid for Multi-site Policy Service Node availability. For the specific situation, a wireless controller sends all authorization to a distant PSN even though a healthy local policy node exists.

C:

This generalization is not valid for Multi-site Policy Service Node availability. All Cisco ISE administration and policy personas perform exactly the same service.

D:

Question 49

A wireless controller sends all authorization to a distant PSN even though a healthy local policy node exists. An operator proposes the following incorrect shortcut: Assume adding a PSN automatically edits every switch AAA configuration. Which negative consequence BEST explains the shortcut’s flaw?

  1. The material consequence is that a justified least-privilege ACL caused every unrelated network authentication fault.
  2. The material consequence is that a correctly recorded TACACS command audit caused the preceding security violation.
  3. The material consequence is that inspecting a correct endpoint certificate generated the original directory outage.
  4. The material consequence is that redundant PSNs do not improve uptime when the access device never targets the backup.

Explanation

Correct Answer

D:

The shortcut is unsuitable because access-device RADIUS high availability depends on the NAD server list and working policy service endpoints. For the specific situation, a wireless controller sends all authorization to a distant PSN even though a healthy local policy node exists.

Question 50

A wireless controller sends all authorization to a distant PSN even though a healthy local policy node exists. The observed failure is: Redundant PSNs do not improve uptime when the access device never targets the backup. How should the administrator correct and verify this failure?

  1. The supported recovery is to disable RADIUS timeouts instead of configuring an alternate server.
  2. The supported recovery is to assume adding a PSN automatically edits every switch AAA configuration.
  3. The supported recovery is to correct NAD AAA server definitions and verify authentication during controlled PSN loss.
  4. The supported recovery is to set all network devices to use the same failed single destination.

Explanation

Correct Answer

C:

Access-device RADIUS high availability depends on the NAD server list and working policy service endpoints. Recheck nAD server group, timeout and retry values, PSN health, network route and successful failover events.
