A. B. C. D.C.
In a Cisco Nexus switch environment, the management access to the switch is provided over an out-of-band network, which is typically a separate dedicated network used for managing the network devices. The out-of-band management network is isolated from the production network, providing an added layer of security.
The Virtual Device Context (VDC) is a feature that allows a physical Nexus switch to be partitioned into multiple logical switches. Each VDC is treated as a separate switch, with its own set of resources such as CPU, memory, and interfaces. This allows multiple departments or tenants to use the same physical switch while maintaining their own isolated network environments.
When it comes to providing out-of-band management access to each VDC, there are different options available:
A. All the VDC have the same out-of-band IP address.
This option would not be ideal as it would mean that all VDCs would share the same management address, which could lead to confusion and make it difficult to troubleshoot issues or perform maintenance tasks.
B. Each VDC has a dedicated out-of-band Ethernet management port.
This option would provide the most secure and efficient method of managing each VDC as it would provide a dedicated and isolated management interface for each VDC. It would also allow for more granular control over access and permissions.
C. Each VDC has a unique out-of-band IP address from the same IP subnet.
This option would allow each VDC to have its own management IP address, but they would all be part of the same subnet, which could cause routing issues or conflicts. It would also make it more difficult to identify which VDC is being managed when looking at the management IP address.
D. Each VDC has a unique out-of-band IP address from different IP subnets among VDCs.
This option would provide each VDC with its own unique management IP address and subnet, which would make it easier to identify and manage each VDC separately. However, it would also require additional routing configurations to ensure connectivity between the different subnets.
In summary, option B, having a dedicated out-of-band Ethernet management port for each VDC, would be the best option for providing out-of-band management access to each VDC on a Cisco Nexus switch.
