You are an Enterprise administrator for contoso.com. The corporate network of the company consists of a single Active Directory domain that contain 100 Windows Server 2003 physical servers having 64-bit hardware.

The company has given you the responsibility to consolidate the 100 physical servers into 30 Windows Server 2008 physical servers and send the remaining physical servers to the new branch office that plans to open shortly.

Which of the following options would you choose to achieve the desired goal while ensuring the maximum resource utilization by using existing hardware and software? You also need to ensure that your solution would support 64-bit child virtual machines and maintain separate services among the servers.

A.
Install the Hyper-V feature on the existing hardware. Then convert the physical machines into virtual machines.

B.
Install the Microsoft Virtual PC. Then convert the physical machines into virtual machines.

C.
Create the necessary host (A) records after consolidating services across the physical machines.

D.
Install Microsoft Virtual Server 2005 R2 on the existing hardware after installing Windows Server 2008 on them. Then convert the physical machines into virtual machines.

E.
None of the above

Explanation:
To ensure the maximum resource utilization by using existing hardware and software and to ensure the support for 64-bit child virtual machines while maintaining separate services among the servers, you need to install the Hyper-V feature to convert the physical machines into virtual machines.

The Hyper-V feature provides Physical-to-Virtual (P2V) Conversion Wizard that guides administrators through the process of creating a virtual version of a physical server, including creating images of physical hard disks, preparing the images for use in a VM, and creating the final VM. The wizard can create virtual servers from physical servers and can run on Windows Server 2003 with SP1 (32-bit only) and on Windows Server 2008 (without Hyper-V role enabled) besides many other Operating systems.
