Answer: In setting up Active Directory Federation Services (AD FS), the following security domains are required:
Resource Partner (RP) Security Domain: This is the domain that contains the web applications or services that will be accessed by users who authenticate through AD FS.
Account Partner (AP) Security Domain: This is the domain that contains the user accounts and credentials that will be used for authentication.
Federation Service Security Domain: This is the domain that hosts the AD FS servers and is responsible for authenticating users and issuing security tokens.
Therefore, the correct answer is:
- Resource Partner (RP) Security Domain
- Account Partner (AP) Security Domain
- Federation Service Security Domain
All three security domains are required for setting up AD FS.
