Which two plug-ins should you configure for PublishingPoint1? (Each correct answer presents part of the solution. Choose two.)

A.
WMS Anonymous User Authentication

B.
WMS IP Address Authorization

C.
WMS Negotiate Authentication

D.
WMS Publishing Points ACL Authorization

Explanation:
WMS Negotiate Authentication
The WMS Negotiate Authentication plug-in grants access to the server based upon the user’s network logon approval. This plug-in uses an encrypted challenge/response scheme to authenticate users. It is a secure form of authentication because the user name and password are not sent across the network; the player acknowledges the password by using a cryptographic exchange with the Windows Media server. Because this plug-in relies upon established user logon credentials, the player and server must be on the same domain or on trusted domains. Negotiate authentication does not work across proxy servers or other firewall applications.
