Dynamic Routing provides the ability to select the best route based on routing metrics.

• A. True
• B. False
• C. Not sure
• D. Not applicable

Answer: (B)

Routing decisions in dynamic routing rely on metrics that rate how good a path is. A routing protocol assigns a cost to each possible route to a destination, and the router installs the route with the lowest cost into its forwarding table. Different protocols define metrics in different ways: RIP uses hop count, OSPF uses a cost based on link bandwidth, and EIGRP uses a composite metric that can include bandwidth, delay, reliability, and load. Because these protocols regularly exchange updates and recalculate costs as the network changes, the router can automatically switch to a better path if a link fails or its conditions worsen. While administrative distance can influence which routes are accepted from different protocols, the concept of selecting the best path based on routing metrics is the core mechanism dynamic routing uses to forward packets efficiently.
