MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -Virtual networks can be created by using a software-defined networking (SDN) controller to configure network devices, such as switches and routers. They can also be created by using a virtual private network (VPN) service to connect to a remote network. Virtual networking has many benefits over physical networking.

Detailed explanation-2: -While physical networking connects computers through cabling and other hardware, virtual networking extends these capabilities by using software management to connect computers and servers over the Internet.

Detailed explanation-3: -A virtual switch (vSwitch) is a software program that enables one virtual machine (VM) to communicate with another. Virtual switches are also used to establish connections between virtual and physical networks and to carry a VM’s traffic to other VMs or a physical network.

Detailed explanation-4: -Virtual networks form their connections through the internet. Virtual network servers create a network that has no direct physical connection, but one that allows file sharing and communication. Some organisations use virtual networks to enable users at home to connect to the organisation’s data and facilities.

Detailed explanation-5: -Network virtualization software allows network administrators to move virtual machines across different domains without reconfiguring the network. The software creates a network overlay that can run separate virtual network layers on top of the same physical network fabric.
