Question

The management of the Cisco Nexus switches is provided over an isolated put-of-band network. The VDC feature is configured on the Cisco Nexus core switches. How is out-of-band management access provided for each VDC?

Options

  • AAll the VDC have the same out-of-band IP address.
  • BEach VDC has a dedicated out-of-band Ethernet management port.
  • CEach VDC has a unique out-of-band IP address from the same IP subnet.
  • DEach VDC has a unique out-of-band IP address from different IP subnets among VDCs.

Explanation

Virtual Device Contexts (VDC) allow you to carve out multiple virtual switches from a single physical Nexus switch Each VDC is logically isolated from every other VDC on a switch. Therefore just like with physical switches, in order to trunk or route traffic between them, physical interfaces and cabling is required to connect two or more VDCs together before this can happen. A useful VDC feature is that the mgmt0 interface on the Supervisor can be assigned a different IP address by each VDC. VDC management can be done via virtualizing the management port so that, each VDC will get logical instance of management port and where we have to provide the separate IP address to each Virtual management Port present in VDC from the same subnet.
