Which VMware Single Sign-On component issues Security Assertion Markup Language (SAML) tokens?

A.    VMware Security Token Service
B.    Administration Server
C.    VMware Directory Service
D.    Identity Management Service

Answer: A
Explanation:
The security token service issues Security Assertion Markup Language (SAML) tokens. These security tokens pass information about a system user between an identity provider and a web service.

QUESTION 35
Which two are valid Identity Sources when configuring vCenter Single Sign-On? (Choose two.)

A.    Radius
B.    NIS
C.    OpenLDAP
D.    LocalOS

Answer: CD
Explanation:
Active Directory (Integrated Windows Authentication) Use this option for native Active Directory implementations. The machine on which the vCenter Single Sign-Onservice is running must be in an Active Directory domain if you want to use this option.
See Active Directory Identity Source Settings.
Active Directory as an LDAP Server
This option is available for backward compatibility. It requires that you specify the domain controller and other information. See Active Directory LDAP Server and OpenLDAP Server Identity Source Settings.
OpenLDAP
Use this option for an OpenLDAP identity source. See Active Directory LDAP Server and OpenLDAP Server Identity Source Settings.
LocalOS
Use this option to add the local operating system as an identity source. You are prompted only for the name of the local operating system. If you select this option, all users on the specified machine are visible to vCenter Single Sign-On, even if those users are not part of another domain.

QUESTION 36
An administrator needs to create an Integrated Windows Authentication (IWA) Identity Source on a newly deployed vCenter Server Appliance (VCSA).
Which two actions will accomplish this? (Choose two.)

A.    Use a Service Principal Name (SPN) to configure the Identity Source.
B.    Use a Domain administrator to configure the Identity Source.
C.    Join the VCSA to Active Directory and configure the Identity Source with a Machine Account.
D.    Create a computer account in Active Directory for the VCSA and configure the Identity Source.

Answer: AC
Explanation:
Using a machine account when configuring an Active Directory identity source for vCenter Server requires that the Windows system be joined to the domain. If the system is not joined to the domain, SSO cannot leverage the machine account to create the identity source and perform its function as the secure token service user.
To resolve this issue in VCVA 5.5, use only the Use SPN option.
