Question:
What are the three major components of cisco network virtualization? (Choose Three)
- network access control
- path isolation
- virtual network services
- policy enforcement
Explanation: Network virtualization architecture has three main components:
+ Network access control and segmentation of classes of users: Users are authenticated and either allowed or denied into a logical partition. Users a re segmented into employees, contractors and consultants, and guests, with respective access to IT assets. This component identifies users who are authorized to access the network and then places them into the appropriate logical partition.
+ Path isolation: Network isolation is preserved across the entire enterprise: from the edge to the campus to the WAN and back again. This component maintains traffic partitioned over a routed infrastructure and transports traffic over and between isolated partitions. The function of mapping isolated paths to VLANs and to virtual services is also performed in component.
+ Network Services virtualization: This component provides access to shared or dedicated network services such as security, quality of service (QoS), and address management (Dynamic Host Configuration Protocol [DHCP] and Domain Name System [DNS]). It also applies policy per partition and isolates application environments, if required.
