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?

When a user receives an 'EAP-TLS authentication failed' message when moving between remote sites, it indicates that the PSN nodes at these sites are not recognizing the user's device. In a Cisco Identity Services Engine (ISE) deployment with multiple Policy Service Nodes (PSNs), it's important to ensure that devices are consistently added to all relevant PSN nodes to maintain a cohesive authentication experience. By adding the device to all PSN nodes in the deployment, the user will be able to authenticate seamlessly at any remote site.
For me the best answer here is the D.
