Answer:
a ticket-granting-ticket which asserts the authenticity of the user's credentials to other network resources.
Step-by-step explanation:
Kerberos is an authentication protocol designed to ensure security when communicating over a public or non-secure network by using symmetric key cryptography.
When a user first authenticates with a Kerberos-based server, he/she will receive a ticket-granting-ticket which asserts the authenticity of the user's credentials to other network resources.
