Which two are types of network virtualization? (Choose two.)
|
A. |
VSS: Virtual Switching System |
|
B. |
VRF: virtual routing and forwarding |

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

remote access services |
Correct Answer: ABCE
Explanation:
An architecture framework for media services supports different models of video models. As shown in Figure 14-13, the network provides service to video media in the Media Services Framework. Those services are access services, transport services, bridging services, storage servers, and session control services, which arc provided to endpoints. Access services provide identity of end devices, mobility, and location services. Transport services provide QoS for reliable packet delivery. Bridging services provide transcoding, conferencing, and recording services of media streams.
Storage services provide capture and storage of media streams and content management and distribution.
Session control services provide session signaling and control and gateway services.
