Using symmetric key cryptography, Kerberos authenticates clients to other entities on a network and
facilitates communications through the assignment of:

A.
Tokens.

B.
Passwords.

C.
Public keys.

D.
Session keys.

Explanation:
The correct answer is “Session keys”. Session keys are temporary keys assigned by the KDC and used
for an allotted period of time as the secret key between two entities. Answer a is incorrect because
it refers to asymmetric encryption that is not used in the basic Kerberos protocol. Answer Passwords
is incorrect because it is not a key, and answer Tokens is incorrect because a token generates
dynamic passwords.
