Which option describes Cisco’s virtual device context feature?
A. logical virtualization of a single physical switch
B. logical witches aggregated into a single physical switch
C. logical switches aggregated into multiple physical switches
D. multiple physical switches partitioned to a single virtual switch
Answer = A
logical virtualization of a single physical switch
Answer=A
“Cisco NX-OS introduces support for virtual device contexts (VDCs), which allows the switches to be virtualized at the device level. Each configured VDC presents itself as a unique device to connected users within the framework of that physical switch. The VDC runs as a separate logical entity within the switch, maintaining its own unique set of running software processes, having its own configuration, and being managed by a separate administrator. ”
“VDCs in the Cisco NX-OS Software platform extend virtualization support to enable true device virtualization. Virtualization of the physical switch offers a number of operational benefits such as greater fault isolation, leading to improved availability”
