You are developing an ASP.NET MVC application to be used on the Internet. The environment uses Active
Directory with delegation to access secure resources.
Users must be able to log on to the application to maintain their personal preferences.
You need to use the least amount of development effort to enable users to log on.
What should you do?

A.
Enable Forms authentication

B.
Enable Windows authentication

C.
Generate server SSL certificates and install them in IIS

D.
Enable Digest authentication

Explanation:
Requirements for Delegation
Delegation relies on Integrated Windows authentication to access resources. There is no limit on the number of
computers that you can delegate your account — you must correctly configure each of them. The Integrated
Windows authentication method works only if the following two conditions exist:
/ You set up your network to use the Kerberos authentication protocol that requires Active Directory.
/ You set up the computers and accounts on your network as trusted for delegation.
