   A network administrator is deploying a dynamic routing protocol in a network with limited bandwidth on the WAN links. The administrator is concerned about the amount of control traffic the protocol will generate. Which action would most effectively reduce the bandwidth consumed by the routing protocol?

   • AIncrease the hello and dead intervals on the WAN interfaces
   • BDisable the routing protocol on the WAN interfaces
   • CDecrease the hello and dead intervals to detect failures faster
   • DUse a routing protocol that does not send hello packets

   In terms of scalability, how do dynamic routing protocols compare to static routing?

   • ADynamic routing protocols scale better because they automatically adapt to network growth.
   • BDynamic routing protocols cannot scale beyond a single autonomous system.
   • CBoth scale equally because they use the same routing table structure.
   • DStatic routing scales better because it uses less CPU.

   A junior network engineer is reviewing the routing table on a router and sees routes that were not manually configured. The engineer asks why these routes are present. Which explanation correctly describes the source of these routes?

   • AThey were manually added by another administrator and are not visible in the configuration
   • BThey were learned from neighboring routers through a dynamic routing protocol
   • CThey are default routes automatically generated by the router's operating system
   • DThey are routes to directly connected networks that appear automatically

   What is the primary characteristic of a dynamic routing protocol?

   • AIt requires the network administrator to manually configure every route on every router.
   • BIt automatically discovers and maintains routes by exchanging information with neighboring routers.
   • CIt only works within a single broadcast domain and cannot route between subnets.
   • DIt uses a single default route for all destinations, eliminating the need for a routing table.

   A network administrator is explaining the benefits of dynamic routing to a manager. The manager asks, 'What is the main advantage of using a dynamic routing protocol over static routing?' Which response is the most accurate?

   • ADynamic routing protocols use less CPU and memory than static routing
   • BDynamic routing protocols automatically adapt to network changes, reducing the need for manual configuration
   • CDynamic routing protocols guarantee the fastest path to every destination
   • DDynamic routing protocols eliminate the need for routers to maintain a routing table
