   A branch site has a static route to a remote subnet. The administrator wants to ensure that if the next-hop IP becomes unreachable, the route is removed from the routing table. Which feature should be configured?

   • ARedistribution of the static route into a dynamic protocol
   • BA tracking mechanism that monitors the next-hop reachability
   • CA lower administrative distance on the static route
   • DA higher metric on the static route

   What is a common cause of routing problems in an SD-WAN environment when both static and dynamic routes are configured?

   • AThe routing protocol using a different metric than the static route
   • BThe SD-WAN device running out of memory due to too many routes
   • CA static route with a lower administrative distance overriding a dynamic route to the same destination
   • DThe dynamic routing protocol automatically disabling itself when a static route is present

   An SD-WAN branch is running OSPF with a core router. The branch is not learning a specific route that the core router is advertising. The OSPF neighbor is up, and other routes from the core are being learned. Which troubleshooting step is most likely to identify the issue?

   • ACheck if a route filter is blocking the specific route on the branch
   • BCheck the OSPF area ID on both routers
   • CIncrease the OSPF metric on the core router
   • DVerify the OSPF hello and dead timers

   A branch site has a static default route pointing to the SD-WAN fabric and also runs OSPF with a local router. The administrator wants OSPF to be preferred for the default route when the OSPF neighbor is up, but fall back to the static default if OSPF goes down. Which configuration approach achieves this behavior?

   • ARedistribute the static default route into OSPF and rely on OSPF metric
   • BSet the OSPF default route's administrative distance lower than the static route's administrative distance
   • CIncrease the OSPF hello and dead timers to make convergence faster
   • DSet the static route's administrative distance lower than OSPF's administrative distance

   What is the function of a route filter in an SD-WAN routing configuration?

   • ATo increase the speed of the routing protocol's convergence
   • BTo automatically generate static routes for all connected networks
   • CTo encrypt routing updates between routers
   • DTo control which routes are advertised to or accepted from neighboring routers
