Your network consists of one Active Directory domain named contoso.com. The domain contains
three Windows Server 2008 servers named Server1, Server2, and Server3. Server1 runs Active
Directory Certificate Services (AD CS) and is configured as an enterprise root certification authority.
Server2 hosts an internal Web site. Users currently connect to the Web site by using the URL
https://server2.contoso.com. You plan to replicate the Web site from Server2 to Server3. You need
to recommend a solution to enable users to connect to the Web site through HTTPS on either
Server2 or Server3 by using a single URL The solution must meet the following requirements:
Users must be able to use the https://www.contoso.com URL to connect to the Web site.
Incoming connections must be dynamically balanced between Server2 and Servers3.
What should you recommend?

A.
Add both servers to a Network Load Balancing cluster. Export the Web server certificate on
Server2 to Server3.

B.
Add both servers to a failover cluster. Issue a Web server certificate forwww.contoso.com. Install
the certificate on Server2.

C.
Add both servers to a Network Load Balancing cluster. Issue a Web server certificate for
www.contoso.com.Install the certificate on Server2 and Server3.

D.
Add both servers to a failover cluster. Issue a Web server certificate for server2.contoso.com and
install the certificate on Server2. Issue a Web server certificate for server3.contoso.com and install
the certificate on Server3.

Explanation:
To connect to the Intranet website through HTTPS on either Server2 or Server3 by using a single URL,
https://www.contoso.com add both servers to a Network Load Balancing cluster so that the client
requests can be load balanced between both the servers and both the servers should be able to
serve the request. You should not use a failover cluster because you don’t want another server to
support if one of the servers fails. Next to make a secure intranet connection, you need to issue a
web server certificate for www.contoso.com, which is the default web URL and includes both the
intranet servers. You should not issue a Web server certificate for server2.contoso.com or
server3.contoso.com because that will take care of only one web server whereas the common URL
will take care of both the servers. Next you need to install the certificate on both Server2 and
Server3 because to use certificates they must be installed on both the servers.
