As a previous reviewer has done, I will include the question here that they were so keen on: If a physically inaccessible computer attached to your local network segment is firewalling all IP traffic, how would you find out if it is up or not? [Hint: this question is very precisely worded.] They eluded to the fact that they intended the answer to be using a switch to find arp record for the device. As they had said the question is very precisely worded - they had not included the use of a switch in the question - some very small office networks just have a dumb hub that doesn't let you do this but hey, why worry about playing by your own, precisely worded rules?
