Correct Answer: BD
Explanation/Reference:
Explanation:
The VSM utilizes three network interfaces that provide separate functions. They are the following:
Network Adapter 1 – control interface: This interface is used to communicate to and from the VSM to VEM. The communication between the VSM and VEM is done through Layer 2 as the default, which requires the VSM Control Interface and also that all of the VEMs are on the same Layer 2 domain (same VLAN). Layer3 support is available as well.
Network Adapter 2 – management interface: This interface is used for administrative connectivity to the VSM, which is the management 0 interface. Layer 3 support is available on this interface for VSM to VEM communication and is the recommended interface to be used.
Network Adapter 3 – packet interface: This interface is used for the Cisco Nexus 1000V protocols, such as Cisco Discovery Protocol (CDP) and multicast traffic. Communication on this interface occurs only between VSM and VEM.
