Why each option

Kerberos primarily relies on symmetric-key cryptography, using a shared secret key between the client, server, and Key Distribution Center (KDC) for authentication.

ATrue

True would imply Kerberos uses public/private key pairs for its core operations, which is incorrect; it relies on shared secret keys.

BFalseCorrect

False. Kerberos is fundamentally built upon symmetric-key cryptography, where both the client and the KDC, and the KDC and the target server, share a secret key.
