Select two actions that occur in the data plane.

The data plane (forwarding plane) handles the actual forwarding of user traffic. Adding or removing an 802.1Q trunking header is a data plane function because it involves modifying frames as they traverse the network device. Matching the destination MAC address to the MAC address table is also a data plane function, as it determines the outbound interface for a frame. Running routing protocols is a control plane function, as it builds the routing table. Making a configuration change via NETCONF is a management plane function. Replying to an ICMP echo request is typically a control plane function, as the device itself is the target of the request, not forwarding user data.
