Company XYZ branch offices connect to headquarters using two links, MPLS and Internet.

A (Policy-based routing):Allows classification of traffic based on source, destination, or protocol and applies forwarding policies accordingly, such as sending VoIP over MPLS and best-effort traffic over either link. PBR operates in fast-path switching modes to avoid process switching if properly configured.

Other options explained:

B: Virtual links relate to OSPF, not traffic steering.

C: Visualization is not a network forwarding technology.

D: Floating static routes select one link for all traffic, not per-traffic-type control.
