I'm kinda wondering about a question I got asked on my CCENT exam.
In a new network setup consisting of a host connected to a switch connected to a router- a serial link then another switch at the far end with a host/server is attached. Why the first ping failed.
The options were a. it had to look up the mac entry for he host in the addresstable, b. it had to do an arp and dns request... there were three more answers I really can't remember but didn't stick in my mind cos I am pretty sure they were out in space.
Does anyone have a definitive answer on this. The question had no router configs or show outputs, but simply stated the network was configured correctly. I rmember my instructor saying this would happen, and it was normal, but he did not say why. I have been over my notes and coursework and though all (even the printed matter and videos) say this will happen none give an explanation. I have asked a couple of friends who are more Qulified but none seem to have a definate answer... it's kinda bugging me.
