What is a benefit of Kerberos authentication?

The correct answer is B. Kerberos securely authenticates clients in a nonsecure environment.. Kerberos was specifically designed by MIT to provide strong, mutual authentication over inherently insecure networks. It achieves this without transmitting passwords in plaintext - instead it uses time-limited tickets issued by a trusted Key Distribution Center (KDC), so credenti

Explanation

Kerberos was specifically designed by MIT to provide strong, mutual authentication over inherently insecure networks. It achieves this without transmitting passwords in plaintext - instead it uses time-limited tickets issued by a trusted Key Distribution Center (KDC), so credentials are never exposed on the wire even if the network is compromised. Option A is incorrect because Kerberos strictly requires clock synchronization (typically within 5 minutes) to prevent replay attacks - mismatched clocks cause authentication failures. Option D is incorrect because the KDC is a single point of failure. Option C is incorrect as Kerberos has infrastructure complexity that makes deployment non-trivial.
