A. All the routes are in the passive mode because R1 is in the query process for those routes.
B. R1 is in AS 200.
C. R1 will load balance between three pat hs to reach the 192.168.1.48/28 prefix because all three paths have the same advertised distance (AD) of 40512000.
D. 40512000 is the advertised distance (AD) via 192.168.1.66 to reach the 192.168.1.48/28 prefix.
E. All the routes are in the passive mod e because these routes are in the hold- down state.
F. The best path for R1 to reach the 192.168.1.48/28 prefix is via 192.168.1.66.

A. A hub router prevents routes from being advertised to the remote router.
B. Only remote routers are configured as stubs.
C. Stub routers are not queried for routes.
D. Spoke routers connected to hub routers answer the route queries for the stub router.
E. A stub router should have only EIGRP hub routers as neighbors.
F. EIGRP stub routing should be used on hub routers only.

A. An EIGRP route will go active if there are no successors or feasible successors in the EIGRP topology table.
B. An EIGRP route will go passive  if there are no successors in the EIGRP topology table.
C. DUAL will trigger an EIGRP query process while placing the flapping routes in the holddown state.
D. A feasible successor in the EIGRP topology table can become the successor only after all the query requests have been replied to.
E. The stuck in active state is caused when the wait for the query replies have timed out.
F. EIGRP queries are sent during the loading state in the EIGRP neighbor establishment process.

A. When summarization is configured, the router will also create a route to null 0.
B. The summary route remains in the route table, even if there are no more specific routes to the network.
C. Summarization is configured on a per- interface level.
D. The maximum metric for the specific routes is used as the metric for the summary route.
E. Automatic summarization across major network boundaries  is enabled by default.

B.On R4, the 172.16.1.0/24 route has a metric of 20
C.The R3 S0/0 interface should not need the no ip split - horizon eigrp 1 configuration command for the  172.16.1.0/24 route to appear in the routing table of R2 as an D EX route
D.The administrative distance of the 172.16.1.0/24 route in the routing table of R3 is 170
E.On R5, the 4.0.0.0/8 route will have an administrative distance of 120 and a hop co unt of 6

B. Router R1 can send traffic destined for network 10.6.1.0/24 out of interface FastEthernet0/0.
C. Router R1 is waiting for a reply from the neighb or 10.1.2.1 to the hello message sent out before it declares the neighbor unreachable.
D. Router R1 is waiting for a reply from the neighbor 10.1.2.1 in response to the query sent out about network 10.6.1.0/24.
