Refer to the exhibit. In this network， R1 is configured not to perform autosummarization within EIGRP. What routes will R3 learn from R2 through EIGRP？ （）
A. 172.30.1.0/24 and 10.1.2.0/24；EIGRP only performs autosummarization at the edge between two major networks.
B. 172.30.0.0/16 and 10.1.2.0/24；R2 will perform autosummarization although R1 will not.
C. Since R2 is configured without autosummarization， it will not propagate the 172.30.1.0/24 route.
D. 172.30.0.0/8 and 10.0.0.0/8.
Refer to the exhibit. In this network， R1 has been configured to advertise a summary route， 192.168.0.0/22， to R2. R2 has been configured to advertise a summary route， 192.168.0.0/21， to R1. Both routers have been configured to remove the discard route （the route to null created when a summary route is configured） by setting the administrative distance of the discard route to 255. What will happen if R1 receives a packet destined to 192.168.3.1？（）
A. The packet will loop between R1 and R2.
B. It is not possible to set the administrative distance on a summary to 255.
C. The packet will be forwarded to R2， where it will be routed to null0.
D. The packet will be dropped by R1， since there is no route to 192.168.3.1.
A.Upgrade the switches
B.Configure BPDU guard
C.Configure VLAN access lists
D.Configure port security
E.Configure Dynamic ARP inspection

In Layer 2 topologies， spanning-tree failures can cause loops in the network. These unblocked loops cancause network failures because of excessive traffic. Which two Catalyst 6500 features can be used to limitexcessive traffic during spanning-tree loop conditions？（）

An expanding company is deploying leased lines between its main site and two remote sites. Thebandwidth of the leased lines is 128kb/s each，terminated on different serial interfaces on the main router.These links are used for combined VOIP and data traffic. The network administrator has implemented a VOIP solution to reduce costs，and has therefore reserved sufficient bandwidth in a low latency queue oneach interface for the VOIP traffic. Users now complain about bad voice quality although no drops areobserved in the low latency queue. What action will likely fix this problem？（）

If the link between PG-R1 and PG-R2 fails， what is the maximum number of queries PG-R3 will receive for 192.168.1.0/24， assuming that all the packets sent during convergence are transmitted once （there are no dropped or retransmitted packets）？（）
Two routers configured to run BGP have been connected to a firewall， one on the inside interface and one on the outside interface.

What is agood first test to see if BGP will work across the firewall？（）
