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
A. Attempt to TELNET from the router connected to the inside of the firewall to the router connected to the outside of the firewall. If telnet works， BGP will work， since telnet and BGP both use TCP to transport data.
B. Ping from the router connected to the inside interface of the firewall to the router connected to the outside interface of the firewall. If you can ping between them， BGP should work， since BGP uses IP to transport packets.
C. There is no way to make BGP work across a firewall without special configuration， so there is no simple test that will show you if BGP will work or not， other than trying to start the peering session.
D. There is no way to make BGP work across a firewall.
A.Change your Internet provider.
B.Change your public IP address.
C.Allow the email server to send traffic only to TCP port 25.
D.Put your email server in a DMZ.
E.Use a separate public IP address for your email server only.
A. Port 3/12 was already up and forwarding before the loop was created.
B. Port priority is based on lowest priority and lowest port number.
C. You connected the wire on port 3/18 last.
D. None of the above， it is purely random.
A.Increase memory allocation for ACLs.
B.Remove all entries from the ACL and use a single permit ip any any statement.
C.Remove the log keyword from each ACL entry.
D.Reboot the device after the ACL has been applied.
