B. There is a missing packet VLAN in the VSM configuration.
C. VSM has no network connection to vCenter.
D. The VSM extension key is not installed on vCenter.
E. The vCenter extension key is not installed on VSM.
Correct Answer: D
Explanation/Reference:
Explanation:
The VSM uses the extension key when communicating with the vCenter Server. Each VSM has its own unique extension key, such as Cisco_Nexus_1000V_32943215
Use the show vmware vc extension-key command to find the extension key of the VSM. It is also listed in the .xml file.
The extension key registered on the vCenter Server can be found through the MOB.
The same extension key cannot be used to create more than one DVS on the vCenter Server.
