Explanation

Deploying multiple links at the enterprise exit (also called WAN redundancy or multi-homing) directly improves reliability by eliminating single points of failure - if one link goes down, traffic fails over to the remaining link(s), keeping the network operational. This is a foundational principle of high-availability network design, where redundancy at critical egress points ensures business continuity. Option B is incorrect because a single exit link creates a bottleneck and a single point of failure, meaning any outage at that link would sever all external connectivity.

Memory tip: Think "multiple exits = multiple escape routes" - just as a building with multiple emergency exits is safer than one with a single door, a network with multiple WAN links is more resilient than one relying on a single connection.
