Which of the following are true concerning authentication within a Cisco Unified Computing
System?
A.
Authentication domains are used to leverage individual authentication systems.
B.
You can create up to 64 authentication domains, each associated with a provider group and
realm in Cisco Unified Computing System Manager.
C.
At login, the user can select the authentication domain to be used.
D.
Cisco Unified Computing System supports LDAP or RADIUS for remote authentication.
E.
A locally authenticated user account is authenticated directly through the fabric interconnect.
The answer here is just worded badly
Cisco UCS supports two methods to authenticate user logins:
• Local to Cisco UCS Manager
• Remote through one of the following protocols:
◦ LDAP
◦ RADIUS
◦ TACACS+
Would have though the answer should be a locally authenticated user accounts is authenticated through the Cisco UCS manager
but see this for details

D is close but as it does not include TACACS as a remote option this is wrong
B is wrong because you can create up to only eight authentication domains
A is wrong as authentication domains are used by Cisco UCS Manager to leverage multiple authentication systems
C is wrong as when logging into the UCs there is no option to select the authentication domain
