Which two network actions occur within the data plane?
(Choose two)
A. Run routing protocols.
B. Make a configuration change from an incoming NETCONF RPC.
C. Add or remove an 802.1Q trunking header.
D. Match the destination MAC address to the MAC address table.

Solution
Correct answer: C. Add or remove an 802.1Q trunking header and D. Match the destination MAC address to the MAC address table.
The data plane is responsible for the forwarding and switching of data packets, which includes tasks like adding or removing VLAN tags (802.1Q trunking) and looking up the destination MAC address in the MAC address table.
The other options are not part of the data plane:
A. Running routing protocols is a control plane function.
B. Making a configuration change from an incoming NETCONF RPC is a management plane function.
E. Replying to an incoming ICMP echo request is a control plane function.
