Why each option

Without the exhibit, a true description of the Cisco Nexus 1000V series switch configuration is that its `mgmt0` interface is typically a Layer 2 interface.

APacket VLAN is a private VLAN

The statement 'Packet VLAN is a private VLAN' describes a specific and optional configuration that is not universally true for all Nexus 1000V deployments.

BVSM connects to the VMware vCenter server

While the VSM does connect to the VMware vCenter server, this describes a functional relationship rather than a specific 'configuration' of the switch itself.

CMgmt0 is a Layer 2 interfaceCorrect

The `mgmt0` interface on a Cisco Nexus 1000V Virtual Supervisor Module (VSM) is commonly configured as a Layer 2 interface. This interface is primarily used for management plane connectivity, enabling the VSM to communicate with the VMware vCenter server and other management entities within the network.

DSVS mode is set to L3

The SVS (Switch Virtualization System) mode, which dictates VSM-VEM communication, can be L2 or L3; asserting it is definitively 'L3' without context from the exhibit is incorrect.
