   How does a dynamic routing protocol differ from static routing in terms of route updates?

   • ADynamic routing protocols only update routes during maintenance windows.
   • BDynamic routing protocols automatically update the routing table when network changes occur.
   • CStatic routing automatically updates routes based on link state advertisements.
   • DDynamic routing protocols require manual reconfiguration whenever the network topology changes.

   What is a disadvantage of dynamic routing protocols related to network bandwidth?

   • AThey use bandwidth to exchange routing information with other routers.
   • BThey reduce bandwidth usage by compressing all data traffic.
   • CThey require dedicated high-bandwidth links for all connections.
   • DThey eliminate the need for bandwidth management.

   A small business has a single router connecting its office network to an ISP. The office has one internal subnet (192.168.1.0/24) and uses a single default route to the ISP. The business has no plans to add additional sites or redundant links. Which routing approach is most appropriate for this environment?

   • ADeploy OSPF to allow the router to automatically detect the ISP's network
   • BUse static routing with a default route and a route to the internal subnet
   • CUse a dynamic protocol to reduce the administrative overhead of the default route
   • DImplement BGP to exchange routes with the ISP for better redundancy

   Which of the following is a key advantage of using a dynamic routing protocol?

   • AIt guarantees that all routes will use the shortest path at all times.
   • BIt requires no CPU or memory resources on the router.
   • CIt reduces administrative overhead by automatically discovering and maintaining routes.
   • DIt eliminates the need for routing tables on all routers.

   A network administrator is choosing between OSPF and static routing for a network with 50 routers. The network is expected to grow by 10 routers per year. The administrator is concerned about the CPU and memory overhead of OSPF on the smaller routers. Which approach best balances scalability with resource constraints?

   • AUse OSPF on all routers and accept the CPU and memory overhead
   • BUse OSPF on the core routers and static routing on the smaller edge routers
   • CUse static routing on all routers to avoid the overhead
   • DUse a distance-vector protocol like RIP instead of OSPF
