In EAP-TLS authentication, what is required on the client side?

A valid client certificate and private key

A hospital network uses Cisco ISE for wireless access. They want to deploy certificate-based authentication for all staff laptops using EAP-TLS. The security team requires that only devices with a valid certificate from the internal CA and a certificate that has not been revoked are allowed. Which configuration in Cisco ISE is essential to meet this requirement?

Configure the wireless controller to use PEAP with the internal CA certificate as the server certificate.

Create an authentication policy that uses the certificate authentication profile with the 'Validate Certificate' option enabled and a trust chain that includes the internal CA.

Set up an authorization policy that grants access based on the endpoint's MAC address.

Enable 'Allow Guest Access' in the wireless SSID configuration.

A company wants to authenticate both the machine and the user for network access. They have deployed machine certificates to all company laptops and user certificates to all employees. The requirement is that both machine and user must be authenticated before granting access. Which EAP method should be used?

EAP-TLS with both machine and user certificates in the authentication policy.

PEAP-MSCHAPv2 with machine certificates only.

A network administrator is troubleshooting EAP-TLS authentication failures. The ISE logs show 'Certificate validation failed' for a specific user, but other users with certificates from the same CA can authenticate. The user's certificate is not expired and the CRL is reachable. What should the administrator check next?

Check if the user's certificate has been revoked.

Check if the user's certificate is in the correct format.

Check if the user's certificate is linked to the correct user account.

Check if the user's certificate has the correct key usage.

An organization is deploying EAP-TLS and has a two-tier PKI: a root CA and multiple issuing CAs. ISE has the root CA certificate in its trust store, but not the issuing CA certificates. During testing, all client certificates fail validation. What is the most efficient solution?

Use a single-tier PKI with only a root CA.

Import all issuing CA certificates into ISE's trust store.

Configure ISE to ignore the trust chain and only check the root CA.

Have clients send the full certificate chain during authentication.
