Question:- What is the purpose of using Virtual Machine Port Group?
Answer:- Virtual Machine port group helps for Virtual machine communication.
Question:- Give three reasons for using VMware Workstation
Answer:- Three reasons for using VMware workstation are: • Enables the user to run more than one operating system on a single system • Saves the existing OS configuration in the form of virtual machines. • Allows you to work on different OS without switching between them.
Question:- What are pluggable devices which can be added while Virtual Machine is running?
Answer:- You can add HDDs and NIC while Virtual Machine is running.
Question:- What is the use of Promiscuous Mode?
Answer:- Promiscuous mode is useful when you want to run a virtual machine with network sniffers helps you to capture packet of that network. Moreover, if the promiscuous mode set to accept, all the communication is visible to all the virtual machines.
Question:- What is Cold and Hot Migration?
Answer:- When you migrate powered off or suspended, it is known as cold migration. When you migrate your running power on virtual machines, it is known as hot migration.
