Which two components are part of the MPLS data plane? (Choose two.)
- LIB
- LFIB
- LDP
- FIB
- RIB
Explanation: According to the sources, the MPLS architecture consists of two primary components: the control plane and the data plane . The data plane, also referred to as the forwarding plane, operates as a simple forwarding engine that directs packets based on destination IP addresses or labels . It utilizes two key data structures for this purpose: the Forwarding Information Base (FIB) and the Label Forwarding Information Base (LFIB) . In contrast, components like the RIB, LIB, and protocols such as LDP reside in the control plane, where they are responsible for Layer 3 protocol exchanges and building the tables that the data plane eventually uses for forwarding .
