Windows 2000 uses which of the following as the primary mechanism
for authenticating users requesting access to a network?

A.
Kerberos

B.
Hash functions

C.
Public key certificates

D.
SESAME

Explanation:
While Kerberos is the primary mechanism, system administrators
may also use alternative authentication services running under the
Security Support Provider Interface (SSPI). Answer hash
functions, are used for digital signature implementations. Answer SESAME is incorrect. It is the
Secure European System for
Applications in a Multivendor Environment. SESAME performs
similar functions to Kerberos, but uses public key cryptography to
distribute the secret keys. Answer “Public key certificates” is incorrect, since public key
certificates are not used in the Windows 2000 primary
authentication approach.
