   A network administrator is deploying a dynamic routing protocol in a network with limited router CPU resources. The administrator notices that the routers are experiencing high CPU utilization during route convergence. Which characteristic of dynamic routing protocols is causing this issue?

   • AThe protocol encrypts all routing updates, consuming CPU cycles
   • BThe protocol requires the router to recalculate routes when the topology changes
   • CThe protocol sends periodic full routing table updates every 30 seconds
   • DThe protocol requires a dedicated CPU core for each neighbor

   A company has a single site with 3 routers and 5 internal subnets. The network is stable, and there are no plans for expansion. The administrator wants to minimize the configuration complexity and ongoing maintenance. Which routing approach is most appropriate?

   • AUse a single default route on each router pointing to the internet
   • BDeploy BGP to exchange routes between the internal routers
   • CConfigure a dynamic routing protocol to allow the routers to learn all subnets automatically
   • DUse static routes on each router to define the paths to each subnet

   A network engineer is designing a network for a financial services company. The network has 15 sites, each with two redundant WAN links. The company requires deterministic routing behavior for compliance audits, meaning the path taken by traffic must be predictable and documented. The engineer is concerned that a dynamic routing protocol might introduce unpredictable path selection. Which approach best satisfies both the redundancy requirement and the compliance requirement?

   • AUse a dynamic protocol but disable all route summarization to keep the routing table simple
   • BUse BGP with multiple paths and rely on the best-path selection algorithm
   • CUse static routes with a floating static route for failover
   • DUse OSPF with equal-cost multipath (ECMP) to load-balance traffic

   How does the operational effort of dynamic routing compare to static routing?

   • AStatic routing requires less initial configuration but more ongoing maintenance.
   • BDynamic routing requires more initial configuration but less ongoing maintenance.
   • CBoth require the same amount of configuration and maintenance.
   • DDynamic routing requires no configuration at all.

   A service provider operates a network with 100 customer sites, each connected via a single link. The provider wants to offer redundant connectivity to its customers, but the customers do not want to run a dynamic routing protocol on their own equipment. Which approach allows the provider to offer redundancy without requiring the customer to run a dynamic protocol?

   • AUse a dynamic protocol on the customer equipment and static routes on the provider edge
   • BUse a single static route on the customer equipment and rely on the provider to reroute traffic
   • CUse static routes on the customer equipment and BGP on the provider edge routers
   • DUse a dynamic routing protocol on the provider edge and static routes on the customer equipment with a floating static route
