Answer:
True
Step-by-step explanation:
A guest Operating System (OS) is a secondary OS to the main installed OS which is the host Operating System (OS). Guest OS can either be a part of a partition or a Virtual Machine (VM). This guest OS is used as a substitute to the host OS.
vSphere Web Client can be installed by using a CD-ROM, DVD or ISO image which has the installation image to make a Virtual Machine (VM) functional.
