A technician is troubleshooting authentication issues on a server. It turns out the clock on the server was 72 minutes behind. Setting the clock to the correct time fixed the issue. Given the scenario, which of the following authentication methods was being used?
A. Kerberos
B. CHAP
C. TACACS+
D. RADIUS
Correct Answer: A
Explanation/Reference:
Explanation: Kerberos is a distributed authentication service that allows a process (a client) running on behalf of a principal (a user) to prove its identity to a verifier (an application server, or just server) without sending data across the network that might allow an attacker or the verifier to subsequently impersonate the principal. Kerberos optionally provides integrity and confidentiality for data sent between the client and server.
