Cisco Exam 300-715 Topic 2 Question 90 Discussion

Actual exam question for Cisco's 300-715 exam

Question #: 90
Topic #: 2

An enterprise uses a separate PSN for each of its four remote sites. Recently, a user reported receiving an "EAP-TLS authentication failed" message when moving between remote sites. Which configuration must be applied on Cisco ISE?

AUse a third-party certificate on the network device.

BAdd the device to all PSN nodes in the deployment.

CRenew the expired certificate on one of the PSN.

DConfigure an authorization profile for the end users.

Show Suggested Answer

Suggested Answer: B

When using separate PSNs for different sites, the network device must be added to all PSN nodes in the deployment, so that the device can communicate with the appropriate PSN based on the location of the user1. If the device is not added to all PSN nodes, the user may encounter an EAP-TLS authentication failure when moving between sites, as the device may not be able to reach the PSN that issued the certificate2. The other options are not relevant for this scenario, as they do not address the issue of PSN communication.

Ah, the joys of enterprise networking. I'm sure the correct answer is hidden somewhere in a Cisco manual the size of a phone book.

I think both options could potentially solve the issue, but I would go with C) to address the expired certificate first.

This reminds me of that time I tried to connect to the corporate network from my toaster. Needless to say, the 'EAP-TLS authentication failed' message wasn't the only problem I had that day.

I bet the answer is D. Configuring an authorization profile for the end users sounds like the logical solution here.

Hmm, I'm not sure. Maybe C is the way to go. Renewing the expired certificate on one of the PSN could be the fix.

I see your point, but I still think C is the best choice. Renewing the expired certificate on one of the PSN seems like the most logical step.

I'm not sure about that. D might be the way to go. Configuring an authorization profile for the end users could help.

I agree with you, A could also work. Using a third-party certificate on the network device could be the solution.

But wouldn't adding the device to all PSN nodes help in ensuring seamless authentication across all sites?

I think the correct answer is B. Adding the device to all PSN nodes in the deployment should resolve the issue with the 'EAP-TLS authentication failed' message when moving between remote sites.
