Step-by-step explanation:
The correct answer is False. When using guest OS customization, VMware Tools are required to be installed on the guest OS that is being customized. VMware Tools is a set of utilities that enhance the performance and functionality of the guest operating system when running on a VMware virtual machine. It provides drivers and other software components to enable features like time synchronization, file sharing, copy/paste, and screen resolutions optimization. Without VMware Tools, the customized guest OS may not have full functionality and performance on the virtual machine.
