Cisco 300-715 Practice Test 73
Question 720
A wireless controller accepts initial RADIUS requests but ignores dynamic authorization on a different management source. The observed failure is: A working initial RADIUS Access-Accept does not prove CoA connectivity or secret alignment. Which controlled recovery BEST restores the intended state?
- The supported recovery is to send every CoA to an unrelated monitoring-only IP address.
- The supported recovery is to repair NAD CoA definitions and verify an acknowledged session reauthorization.
- The supported recovery is to treat DNS resolution success as proof the CoA shared secret is correct.
- The supported recovery is to disable CoA authentication for the whole wireless controller.
Explanation
Correct Answer
B:This restores the intended operational behavior for CoA packet source shared secret and NAD handling.
Incorrect Answers
A:Send every CoA to an unrelated monitoring-only IP address. This action does not repair the identified failure. A working initial RADIUS Access-Accept does not prove CoA connectivity or secret alignment. Instead, repair NAD CoA definitions and verify an acknowledged session reauthorization. For the specific situation, a wireless controller accepts initial RADIUS requests but ignores dynamic authorization on a different management source.
C:Treat DNS resolution success as proof the CoA shared secret is correct. This action does not repair the identified failure. A working initial RADIUS Access-Accept does not prove CoA connectivity or secret alignment. Instead, repair NAD CoA definitions and verify an acknowledged session reauthorization. For the specific situation, a wireless controller accepts initial RADIUS requests but ignores dynamic authorization on a different management source.
D:Disable CoA authentication for the whole wireless controller. This action does not repair the identified failure. A working initial RADIUS Access-Accept does not prove CoA connectivity or secret alignment. Instead, repair NAD CoA definitions and verify an acknowledged session reauthorization. For the specific situation, a wireless controller accepts initial RADIUS requests but ignores dynamic authorization on a different management source.
Question 721
An endpoint is classified as untrusted and must be fully disconnected rather than merely assigned the same ACL. What is the BEST supported ISE implementation or corrective action?
- Choose supported CoA reauth or disconnect behavior according to required session and reauthentication handling.
- Assume a CoA notification always disconnects a client irrespective of message type.
- Use only a profiler rule name as a live session termination signal.
- Disable the switch authentication session feature to avoid CoA troubleshooting.
Explanation
Correct Answer
A:Verify the effect through coA message type, session termination, EAP retry and new policy decision. This is the targeted action for CoA disconnect versus reauthentication outcome.
Incorrect Answers
B:Applying a wrong CoA action can leave a disallowed client online or repeatedly flap an authorized port. This does not implement the required control for CoA disconnect versus reauthentication outcome.
C:Use only a profiler rule name as a live session termination signal. This alternative overlooks a required prerequisite or targets the wrong function. CoA reauthentication and disconnect requests affect session state differently. The relevant evidence is coA message type, session termination, EAP retry and new policy decision. For the specific situation, an endpoint is classified as untrusted and must be fully disconnected rather than merely assigned the same ACL.
D:Applying a wrong CoA action can leave a disallowed client online or repeatedly flap an authorized port. Instead the intended policy action is choose supported CoA reauth or disconnect behavior according to required session and reauthentication handling.
Question 722
An endpoint is classified as untrusted and must be fully disconnected rather than merely assigned the same ACL. Which evidence BEST verifies the intended operational outcome?
- A switch interface description without any live AAA request or response.
- CoA message type, session termination, EAP retry and new policy decision.
- An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
- A current login screenshot from a completely unrelated ISE deployment.
Explanation
Correct Answer
B:These observations directly establish the result of CoA disconnect versus reauthentication outcome for the described endpoint or network device. CoA reauthentication and disconnect requests affect session state differently.
Incorrect Answers
A:A switch interface description without any live AAA request or response. This observation cannot verify CoA disconnect versus reauthentication outcome.

Question 723
An endpoint is classified as untrusted and must be fully disconnected rather than merely assigned the same ACL. Which technical principle BEST explains the required decision?
- CoA reauthentication and disconnect requests affect session state differently.
- A captive portal page automatically changes network authorization on every active NAD session without signaling.
- A successful switch port link signal always proves the device identity and policy were verified.
- Every RADIUS Access-Accept grants unrestricted access to all applications.
Explanation
Correct Answer
A:The supported implementation is to choose supported CoA reauth or disconnect behavior according to required session and reauthentication handling. This is the governing technical behavior for CoA disconnect versus reauthentication outcome.
Incorrect Answers
B:A captive portal page automatically changes network authorization on every active NAD session without signaling. This generalization is not valid for CoA disconnect versus reauthentication outcome. Instead coA reauthentication and disconnect requests affect session state differently. Verify the actual state using coA message type, session termination, EAP retry and new policy decision.

Question 724
An endpoint is classified as untrusted and must be fully disconnected rather than merely assigned the same ACL. An operator proposes the following incorrect shortcut: Assume a CoA notification always disconnects a client irrespective of message type. What material risk or failure follows from that shortcut?
- Reading the authentication event report caused the original network access outage.
- The only result is an unrelated portal background color change.
- Accurate device accounting automatically created every earlier failed EAP exchange.
- Applying a wrong CoA action can leave a disallowed client online or repeatedly flap an authorized port.
Explanation
Correct Answer
D:The supported preventive action is to choose supported CoA reauth or disconnect behavior according to required session and reauthentication handling. The shortcut is unsuitable because coA reauthentication and disconnect requests affect session state differently.

A:This unrelated assertion does not explain the CoA disconnect versus reauthentication outcome problem. The relevant risk is that applying a wrong CoA action can leave a disallowed client online or repeatedly flap an authorized port.
B:This unrelated assertion does not explain the CoA disconnect versus reauthentication outcome problem. Check coA message type, session termination, EAP retry and new policy decision.
C:This unrelated assertion does not explain the CoA disconnect versus reauthentication outcome problem. For the specific situation, an endpoint is classified as untrusted and must be fully disconnected rather than merely assigned the same ACL.
