Which of the following would the telecommunications carrier use to segregate customer traffic over
long fiber links?

A.
VLAN

B.
MPLS

C.
VPN

D.
PSTN

MPLS is a mechanism in high-performance telecommunications networks that
directs data from one network node to the next based on short path labels rather than long
network addresses, avoiding complex lookups in a routing table. The labels identify virtual links
(paths) between distant nodes rather than endpoints
