   What is the primary function of Equal-Cost Multi-Path (ECMP) routing in a Layer 3 deployment?

   • ATo reduce the routing table size by summarizing multiple routes into one
   • BTo automatically fail over to a backup path with a higher cost
   • CTo load-balance traffic across multiple equal-cost paths and provide redundancy if one path fails
   • DTo select the single best path based on the lowest administrative distance

   A network engineer is configuring OSPF on a PA-Series firewall that connects to two different OSPF areas. The firewall is an ABR. The engineer needs to redistribute static routes into OSPF. However, the engineer notices that the static routes are being advertised as Type 5 external routes, and some routers in Area 1 are not receiving them. The routers in Area 1 are configured as stub areas. What is the most likely reason for this issue, and what is the correct solution?

   • AThe ABR is not configured to redistribute static routes into Area 1; the engineer should configure redistribution separately for each area.
   • BThe ABR is not generating a default route into Area 1, so the routers cannot reach the external networks.
   • CThe static routes have a higher metric than the OSPF default route, so they are not preferred.
   • DStub areas do not accept Type 5 external routes; the engineer should configure the area as a not-so-stubby area (NSSA) to allow external routes.

   In which scenario is a static route most appropriate?

   • AA small network with a stable topology and a single path to a remote network
   • BA network where routes must be dynamically learned from a service provider
   • CA network that requires automatic failover to multiple redundant paths
   • DA large enterprise network with hundreds of routers and frequent topology changes
