What is the relationship between a Forwarding Equivalence Class (FEC) and the MPLS label that a Label Switching Router (LSR) advertises for that FEC?
The correct answer is B. The LSR assigns a unique label to each FEC, but labels assigned by different LSRs do not. See the full explanation below for the reasoning.

Options
- AAn LSR assigns the same label to FECs with the same best next hop: labels remain constant
- BThe LSR assigns a unique label to each FEC, but labels assigned by different LSRs do not
