Kerberos is a network authentication protocol designed to provide strong authentication for client/server applications by using secret-key cryptography. The Kerberos Key Distribution Center (KDC) is the core component of the Kerberos protocol, and it consists of two main components:

  1. Authentication service: The authentication service is responsible for verifying the identity of users and servers in the Kerberos realm. It runs on the KDC and authenticates users by verifying their passwords or other credentials. It also issues tickets that are used for subsequent authentication requests.

  2. Ticket-granting service: The ticket-granting service is responsible for issuing service tickets to users who request access to network resources. It is also responsible for renewing and revoking these tickets. The ticket-granting service runs on the KDC and is a critical component of the Kerberos authentication process.

Therefore, the correct answers to the question are B. Ticket-granting service and D. Authentication service. The account service and data service are not part of the Kerberos KDC architecture.
