Which statement about hot-potato routing architecture design is true?

Hot-potato routing refers to the practice of routing traffic out of the network as quickly as possible—typically using the shortest IGP path to the egress point. While efficient for internal networks, it can lead to unpredictable routing behavior and suboptimal traffic paths if not coordinated with external peers.

D is correct: Without alignment between internal metrics and external relationships, hot-potato routing can result in asymmetric routing, congestion, or routing loops.

A is incorrect: Content providers often prefer cold-potato routing to control quality of service.

B describes cold-potato routing, where traffic is retained longer.

C is misleading; OSPF doesn’t define hot-potato behavior explicitly—it results from equal-cost metrics and shortest IGP paths.
