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
Explanation:
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
Very good question. In many of cert studies and guides I have met the information about that VSS is “DEVICE VIRTUALIZATION TECHNOLOGY”. But…

“Q. What is a virtual switching system (VSS)?
A. A VSS is network system virtualization technology that pools multiple Cisco ® Catalyst ® 6500 Series Switches into one virtual switch, increasing operational efficiency, boosting nonstop communications, and scaling system bandwidth capacity to 1.4 Tbps. At the initial phase, a VSS will allow two physical Cisco Catalyst 6500 Series Switches to operate as a single logical virtual switch called a virtual switching system 1440 (VSS1440). (See Figure 1.)”
