Network Practical

What is Network Function Virtualization (NFV)?

• A method of physically connecting multiple servers in a data center

• A process of virtualizing all network devices and moving them into the hypervisor

• A way to physically link multiple virtual servers

• A method of installing physical routers and switches in a virtual environment

What is the main responsibility of the hypervisor in a virtualized network?

• Managing physical server racks

• Configuring physical switches and routers

• Managing virtual machines and network connections

• Installing and upgrading physical network devices

In Network Function Virtualization, what replaces physical network components like switches and routers?

• Virtual CPUs

• Virtual network interface cards (vNICs)

• Virtual switches and routers

• Physical network interface cards (NICs)

What feature allows you to add and remove virtual network devices like switches or routers through automation?

• NetFlow

• vNIC

• Hypervisor API

• Port mirroring

Which of the following is NOT a function of a virtual switch?

• NetFlow

• vNIC

• Hypervisor API

• Port mirroring

What is a vNIC used for in virtual machines?

• To physically connect virtual machines to the network

• To provide virtual machines access to the virtual network

• To manage the hypervisor settings

• To configure VLANs in the physical network

What term is used to describe the central location from which all virtual network and machine resources are managed?

• Network Interface Card (NIC)

• Single Pane of Glass

• Virtual Machine Manager (VMM)

• Data Center

What does the hypervisor manage access to for virtual systems?

• VLANs, CPUs, and data centers

• Memory, CPUs, and network connections

• Firewalls, data storage, and VLANs

• Routers, firewalls, and physical servers

How can a hypervisor facilitate adding a new virtual switch to the network?

• Through physical installation of a network card

• By clicking a few buttons in the hypervisor or using its API

What connects the virtual environment to the physical network in NFV?

• Physical network interface cards (NICs)

• Hypervisor uplinks

• VLAN configurations

• Port mirroring
