   A startup has a single site with two routers and a handful of static routes. The network is expected to grow to 50 sites over the next two years, with multiple redundant WAN links between sites. The CTO wants to minimize the operational effort of managing routes as the network scales. What should the network team do to best prepare for this growth?

   • AUse a single default route on all routers pointing to the internet
   • BWait until the network reaches 25 sites before implementing a dynamic protocol
   • CDeploy a dynamic routing protocol such as OSPF to automate route discovery and failover
   • DContinue using static routes but document them thoroughly for future reference

   A network administrator is considering deploying OSPF across a small network of five routers connected by low-bandwidth links. The administrator is concerned about the overhead that a dynamic routing protocol will introduce. Which drawback of dynamic routing protocols is most relevant to this specific concern?

   • AInability to support multiple paths to the same destination
   • BIncreased bandwidth consumption due to hello packets and route updates
   • CRequirement for a dedicated management network for protocol operation
   • DComplete loss of routing functionality during the initial convergence period

   A network has two sites connected by two redundant WAN links. Currently, static routes are configured with a higher preference for the primary link. When the primary link fails, the router does not automatically switch to the backup link because the static route remains in the table. What is the most efficient way to ensure automatic failover?

   • AAdd a second static route with a lower preference to the backup link
   • BConfigure the backup link with a higher metric so it is always used
   • CManually remove the static route for the primary link when it fails
   • DUse a dynamic routing protocol to detect the link failure and update the routing table

   Which of the following is a potential disadvantage of using dynamic routing protocols?

   • AThey require a dedicated router for each network segment.
   • BThey are unable to adapt to network topology changes.
   • CThey consume additional CPU and memory resources on routers.
   • DThey increase the amount of manual configuration required for each route.

   A company operates a regional office with 25 branches, each connected to the main office via a single WAN link. The network team is replacing the current static route configuration because a new branch is added every few months and WAN providers occasionally change the next-hop IP addresses. Which benefit of a dynamic routing protocol directly addresses the operational pain point in this scenario?

   • AAutomatic route discovery and re-convergence when the network topology changes
   • BLower CPU and memory utilization on the edge routers compared to static routes
   • CGuaranteed use of the shortest path to every destination at all times
   • DElimination of all routing loops without any additional configuration
