B. RIP has an administrative distance (AD) of 120, while EIGRP has an administrative distance of 90, so the router will discard any route with a higher AD than 90 to that same network.

D. Recovery from a lost route requires manual intervention by a human to replace the lost route.

A. RIPv1 and RIPv2 only use the lowest hop count to determine the best path to a remote network.
15.
A. Since the routing table shows no route to the 192.168.22.0 network, the router will discard the packet and send an ICMP destination unreachable message out of interface FastEthernet 0/0, which is the source LAN from which the packet originated.

C. Static routes have an administrative distance of 1 by default. Unless you change this, a static route will always be used over any other dynamically learned route. EIGRP has an administrative distance of 90, and RIP has an administrative distance of 120, by default.

C. BGP is the only EGP listed.

D. Recovery from a lost route requires manual intervention by a human to replace the lost route. The advantages are less overhead on the router and network, as well as more security
