A.Attempt to TELNET from the router connected to the inside of the firewall to the router connected to theoutside of the firewall. If telnet works， BGP will work， since telnet and BGP both use TCP to transportdata.
B.Ping from the router connected to the inside interface of the firewall to the router connected to theoutside interface of the firewall. If you can ping between them， BGP should work， since BGP uses IP totransport packets.
C.There is no way to make BGP work across a firewall without special configuration， so there is no simpletest 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.

On the basis of the network provided in the exhibit， all routers are configured to run EIGRP on all links. 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）？（）
A. PG-R3 will receive up to four queries for 192.168.1.0/24， one each from PG-R2， PG-R4， PGR5，and PG-R6.
B. PG-R3 will receive up eight queries for 192.168.1.0/24， one from PG-R2， two from PG-R4，three from PG-R5， and four from PG-R6.
C. PG-R3 will receive one query for 192.168.1.0/24， since the remote routers， PG-R4， PG-R5， and PG-R6， are natural stubs in EIGRP.
D. PG-R3 will not receive any queries from PG-R2， because there are no alternate paths for 192.168.1.0/24.
