Your network consists of one Active Directory domain. All servers run Windows Server 2008 R2.
You plan to publish a Web site on two Web servers. You need to recommend a solution for the
deployment of the two Web servers. The solution must provide the following requirements:
• Session-state information for all users
• Access to the Web site if a single server fails
• Scalability to as many as seven Web servers
• Support for multiple dedicated IP addresses for each Web server
What should you recommend?

A.
Install failover clustering on each Web server.

B.
Install Network Load Balancing on each Web server.

C.
Assign multiple bindings in Internet Information Services (IIS) 7.0.

D.
Create managed handler mappings in Internet Information Services (IIS) 7.0.

Explanation:
To ensure that the users of the website would be able to access the Web site if a single server fails.
The website should be scalable to as many as seven Web servers and the web servers should be able
to store session-state information for all users. It should also provide support for multiple dedicated
IP addresses for each Web server. The Network Load Balancing (NLB) feature in Windows Server
2008 enhances the availability and scalability of Internet server applications such as those used on
Web, FTP, firewall, proxy, virtual private network (VPN), and other mission-critical servers. NLB
provides high availability of a website by detecting and recovering from a cluster host that fails or
goes offline. You should not use failover clustering in this scenario because failover clustering does
not provide scalability.
