Virtualization and Network Function Virtualization

What is network function virtualization (NFV)?

• Replacing physical servers with virtual servers

• Moving the network infrastructure into the hypervisor

• Creating virtual switches and routers

• Deploying multiple VLANs and redundant connections

What are the benefits of network function virtualization (NFV)?

• Reduced physical server requirements

• Ability to add fault tolerance and monitoring services

• Simplified deployment of new switches and routers

• All of the above

What is the role of the hypervisor in network function virtualization (NFV)?

• Managing all virtual systems and operating systems

• Controlling access to CPU, memory, and network

• Providing a central management console

• All of the above

What is a vSwitch in virtualization?

• A physical switch used in virtual environments

• A virtual switch that replaces physical switches

• A network interface card for virtual machines

• A management console for hypervisors

What features are supported by virtual switches?

• NetFlow

• Link Aggregation Control Protocol (LACP)

• Port mirroring

• All of the above

What is a vNIC in virtualization?

• A virtual network interface card

• A physical network interface card

• A virtual switch

• A management console for virtual machines

What can be configured through the hypervisor for vNICs?

• Load balancing

• VLAN capabilities

• Additional monitoring

• All of the above

What is the purpose of the uplink in the hypervisor?

• To connect virtual machines to the physical network

• To manage access to CPU, memory, and network

• To provide a central management console

• To configure virtual switches

What can be done with network connections in the hypervisor?

• Make networks private

• Associate networks with VLANs

• Build complex network configurations

• All of the above

What is the purpose of network function virtualization (NFV)?

• To replace physical servers with virtual servers

• To simplify network management

• To provide additional network capabilities

• All of the above
