Which of the following are most likely to operate in the data plane of a Nexus switch? (Choose two.)

A. BGP
B. EIGRP
C. OSPF

D. store-and-forward switching

E. SNMP

F. cut-through switching

Explanation:

Of the available choices, cut-through switching and store-and-forward switching are most likely to operate in the data plane of a Nexus switch. A Nexus switch consists of three operational planes: the data plane, which is also known as the forwarding plane, the control plane, and the management plane. Of the three, the data plane is where traffic forwarding occurs. Cut-through switching allows a switch to begin forwarding a frame before the frame has been received in its entirety. Store-and-forward switching receives an entire frame and stores it in memory before forwarding the frame to its destination.
Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), and Border Gateway Protocol (BGP) all operate in the control plane of a Nexus switch. The control plane is responsible for gathering and calculating the information required to make the decisions that the data plane needs for forwarding. Routing protocols operate in the control plane because they enable the collection and transfer of routing information between neighbors. This information is used to construct routing tables that he data plane can then use for forwarding.
Simple Network Management Protocol (SNMP) is an Internet Protocol (IP) network management protocol that operates in the management plane of a Nexus switch. The management plane is responsible for monitoring and configuration of the control plane. Therefore, network administrators typically interact directly with protocols running in the management plane.
