Explanation

Kerberos functions as a centralized authentication server that issues tickets to clients, allowing them to prove their identity to any service that trusts the Kerberos realm - making unified, single-sign-on authentication across all cluster services entirely by design. This is precisely why option A is correct: Kerberos was architected from the ground up to serve as a shared authentication backbone, and its ticket-granting mechanism works equally well for built-in cluster services and custom third-party or customer-developed applications, provided they are registered with the KDC (Key Distribution Center). Option B is incorrect because it implies a limitation that doesn't exist - there is no architectural barrier preventing Kerberos from authenticating secondary/custom applications as long as they implement the Kerberos protocol. Memory tip: Think of Kerberos as a "universal ticket booth" - any application in the cluster that accepts Kerberos tickets can rely on it for authentication, regardless of whether it was built by the platform vendor or a customer developer.
