3. WRT Inc. is an energy market research company. The company provides consultancy to clients in the field of crude oil exploration and marketing in form of reposts. The company has a robust IT infrastructure to support the research and marketing operations. The IT department is planning to upgrade the client operating system. To ensure a proper transition to the new operating system, Chris, the Infrastructure Manager, has decided to set up a new virtual lab environment to test the new client operating system. The virtual lab will provide an efficient and cost effective method to test the new client operating system. Brad, the Desktop Administrator, has been assigned the task to set up the lab environment. Brad has analyzed the requirements for setup and identified the following tasks: The new lab setup will use multiple virtual machines with differencing disks based on a common base disk, Win_base, which is kept at the E:\Base location. The base disk has the latest Windows operating system installed. In case the location of the base hard disk is changed, the virtual machine needs to be created with the existing differencing disk based on the new location of the base hard disk. In case the virtual machine is required in an original state after modification, the virtual machine needs to be reverted to the original state. The virtual machine needs to be booted from a CD or a network. To test the setup, Brad decides to create a Win 8 virtual machine at the D:\VHD\Win8 location. After creating the differencing disk, the base will be moved to the D:\Base_new location. How can Brad perform the assigned tasks? Experiment To perform the assigned tasks, Brad need to perform the following tasks: Create a differencing hard disk. Create a virtual machine. Add and configure a virtual hard disk. Create and use snapshots. Boot the virtual machine from CD.
