Which two are types of network virtualization? (Choose two.)
A. VSS: Virtual Switching System
B. VRF: Virtual Routing and Forwarding
C. VCI: Virtual Channel Identifier
D. VLSM: Variable Length Subnet Masking
E. VM: Virtual Machine
F. VMP: Virtual Memory Pool
Correct Answer: AB
Explanation/Reference:
Network virtualization encompasses logical isolated network segments that share the same physical infrastructure. Each segment operates independently and is logically separate from the other segments. Each network segment appears with its own privacy, security, independent set of policies, QoS levels, and independent routing paths.
Here are some examples of network virtualization technologies:
VLAN: Virtual local-area network
VSAN: Virtual storage-area network
VRF: Virtual routing and forwarding
VPN: Virtual private network vPC: Virtual Port Channel
This answer is incorrect. VRF is the only correct option. VSS is a device virtualization technology.
Here are some examples of network virtualization technologies:
■ VLAN: Virtual local area network
■ VSAN: Virtual storage area network
■ VRF: Virtual routing and forwarding
■ VPN: Virtual private network
■ vPC: Virtual Port Channel
Here are some examples of device virtualization technologies:
■ Server virtualization: Virtual machines (VM)
■ Virtual Switching System (VSS)
■ Cisco Adaptive Security Appliance (ASA) fi rewall context
■ Virtual device contexts (VDCs)
