You work as an enterprise administrator at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers on the Domain.com network run Windows Server 2008.
Domain.com contains a server named CERTKILLER-SR11 that has the Active Directory Federation Services (AD FS) role installed. You have received instructions from the CIO to test the connectivity of clients in the network to make sure that they can reach the new Federation server and that the Federation server is operational.
What should you do? (Choose all that apply)

A.
The best option is to check if Active Directory Federation Services is running, in the Services tab.

B.
The best option is to look for event ID 674 in the event viewer, Applications, Event ID column.

C.
The best option is to type the Federation Service URL for the new federation server, in a browser window.

D.
None of the above

Explanation:
To test the connectivity of clients in the network to ensure that they can successfully reach the new Federation server and Federation server is operational, you can look for event ID 674. This event verifies that the federation server was able to successfully communicate with the Federation Service.
You can also open a browser window, and then type the Federation Service URL for the new federation server. The Federation Server Service page should appear along with a list of links that identify the Web methods that the Federation Service uses. The Federation Service URL should include the Domain Name System (DNS) host name of the federation server.
