How is the distance of dynamic routes changed?

• A. Through the dynamic process
• B. By editing static routes
• C. By rebooting the device
• D. By disabling the interface

Answer: (A)

Dynamic routing controls the distance of routes learned through it. The distance shown for these routes comes from the administrative distance the routing protocol assigns to paths it discovers, and the router uses that value to decide which route to prefer when multiple options exist. Because this distance is determined by the dynamic protocol during its operation, changes are made by adjusting the dynamic process or the protocol’s own distance/cost settings. Editing static routes wouldn’t impact dynamic ones, since they carry the protocol’s learned distance. Rebooting the device or disabling an interface can disrupt or remove routes, but they don’t directly change the distance values assigned to dynamic routes.
