Answer: C

Explanation:

Radius service tracking locates the availability of the RADIUS service configured on the switch. It helps to minimize the waiting period for new clients in the unauth-vid (Guest Vlan) when authentication fails because of service is not available, as well as previously authenticated clients in unauth-vid (Guest Vlan) when re-authentication fails because service is not available during the re-authentication period. Note that this feature is disabled by default.
