In which of the following scenarios would the "show cdp neighbors detail"command be an appropriate troubleshooting tool?()
A. Two switches are connected via a trunk. Both switches have been assigned an IP address, subnet mask, and default gateway. A ping is successful between the two switches. However, VLAN information is not passed from one switch to the other switch.B. A router and a switch have been assigned an IP address, a subnet mask, and a default gateway. They are directly connected, but a ping between the two devices fails.C. A router connects to another router through a serial interface. Both routers have been assigned an IP address, subnet mask, and default gateway. The routers are running RIP and the networks directly connected to the first router do not pass to the second router. However, a ping from one router to the serial interface of the directly connected neighboring router is successful.D. A router connects to another router via a switch. Both routers and the switch have been assigned an IP address, subnet mask, and default gateway. Neither the routers nor the switch are able to ping one of the hosts that is directly to the switch.

Two routers configured to run BGP have been connected to a firewall， one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer， including the correct BGP session endpoint addresses and the correct BGP session hop-count limit （EBGP multihop）. What is a good first test to see if BGP will work across the firewall？（）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.
