You need to gather the IP address of a remote switch that is located in Hawaii. What can you do to find the address?
Options
A. Issue the show ip arp command on the router connected to the switch.
B. Issue the show ip route command on the router connected to the switch.
C. Issue the show cdp neighbor command on the router connected to the switch.
D. Issue the show cdp neighbors detail command on the router connected to the switch.
Correct Answer
Issue the show cdp neighbors detail command on the router connected to the switch.
Explanation
Although option A is certainly the "best" answer, unfortunately option D will work just fine and your boss would probably prefer you to use the
show cdp neighbors detail command.

1. You need to subnet a network that has 5 subnets, each with at least 16 hosts. Which classful subnet mask would you use?
You need 5 subnets, each with at least 16 hosts. The mask 255.255.255.240 provides 16 subnets with 14 hosts-this will not work. The mask 255.255.255.224 provides 8 subnets, each with 30 hosts. This is the best answer.
2. Which command is required for connectivity in a Frame Relay network if Inverse ARP is not operational?
If you have a router in your Frame Relay network that does not support IARP, you must create Frame Relay maps on your router, which provide known DLCI-to-IP address mappings.
3. What VTP mode allows you to change VLAN information on the switch?
A CIDR address of /19 is 255.255.224.0. This is a Class B address, so that is only 3 subnet bits, but it provides 13 host bits, or 8 subnets, each with 8,190 hosts.
5. Which command will allow you to see real-time translations on your router?
Any secondary route to a remote network is considered a feasible successor, and those routes are only found in the topology table and used as backup routes in case of primary route failure. You can see the topology table with the
show ip eigrp topology command.
