Which statement best describes the reason for the error messages?

Refer to the exhibit. EIGRP had converged in AS 1 when the link between router R1 and R2
went down. The console on router R2 generated the following messages:
*Mar 20 12:12:06: %DUAL-5-NBRCHANGE: IP-EIGRP 1: Neighbor 10.1.4.3
(Serial0) is down: stuck in active
*Mar 20 12:15:23: %DUAL-3-SIA: Route 10.1.1.0/24 stuck-in-active
state in IP-EIGRP 1. Cleaning up
The network administrator issued the show ip eigrp topology active command on R2 to
check the status of the EIGRP network. Which statement best describes the reason for the
error messages? Select the best response.

What configuration should be done on the routers in autonomous system 100 in order for the traffic coming from

Refer to the exhibit. Autonomous systems 200 and 300 have EBGP sessions established
with their directly connected routers in autonomoussystem 100. IGP has been configured
on all routers in autonomous system 100 and they successfully exchange routing updates.
Traffic originated in autonomous system 200 cannot reach the destination autonomous
system 300. What configuration should be done on the routers in autonomous system 100
in order for the traffic coming from autonomous system 200 to be forwarded to autonomous
system 300? Select the best response.

Which three path features would be reasons be for the router to ignore some of the routes and not consider the

A router is running BGP and receives more than one route for a particular prefix.Assume all
the routes for this prefix have the same attributes. Which three path features would be
reasons be for the router to ignore some of the routes and not consider them as candidates
for the best path? (Choose three.)
