Your network contains a Webbased application that runs on Windows Server 2003. You plan to migrate the Webbased application to Windows Server 2008 R2. You need to recommend a server configuration to support the Webbased application.

The server configuration must meet the following requirements:

– Ensure that the application is available to all users if a single server fails
– Support the installation of .NET applications
– Minimize software costs

What should you recommend?

A.
Install the Server Core installation of Windows Server 2008 R2 Standard on two servers.
Configure the servers in a Network Load Balancing cluster.

B.
Install the full installation of Windows Server 2008 R2 Web on two servers. Configure the servers in a Network Load Balancing cluster.

C.
Install the full installation of Windows Server 2008 R2 Enterprise on two servers. Configure the servers in a failover cluster.

D.
Install the full installation of Windows Server 2008 R2 Datacenter on two servers. Configure the servers in a failover cluster.

Explanation:

Web Edition meets the requirements

Windows Web Server 2008 R2
Windows Web Server 2008 R2 is designed to function specifically as a Web application server.
Other roles, such as Windows Deployment Server and Active Directory Domain Services (AD DS), are not supported on Windows Web Server 2008 R2. You deploy this server role either on a screened subnet to support a website viewable to external hosts or as an intranet server. As appropriate given its stripped-down role, Windows Web Server 2008 R2 does not support the high-powered hardware configurations that other editions of Windows Server 2008 R2 do. Windows Web Server 2008 R2 has the following properties:

: Supports a maximum of 32 GB of RAM and 4 sockets in symmetric multiprocessing (SMP) configuration

You should plan to deploy Windows Web Server 2008 R2 in the Server Core configuration, which minimizes its attack surface, something that is very important on a server that interacts
with hosts external to your network environment. You should plan to deploy the full version of Windows Web Server 2008 R2 only if your organizations web applications rely on features
that are not available in the Server Core version of Windows Web Server 2008 R2. Unlike the Server Core version of Windows Web Server 2008, Windows Web Server 2008 R2 supports
a greater amount of Internet Information Services (IIS) functionality.

Why Failover Cluster will not work.
