I need some help with the following subnet problem:\n\n"You are the new administrator of a 2000 node network.\nThere is only one router on the entire network, which\nprovides all the computers with Internet access. The\ncompany's ISP has assigned the following 8 network\naddresses to them:\n\n10.24.32.0/24\n10.24.33.0/24\n10.24.34.0/24\n10.30.35.0/24\n10.30.36.0/24\n10.30.37.0/24\n10.30.38.0/24\n10.30.39.9/24\n\nWhat subnet mask could you use to minimize the complexity\nof the routing tables while maintaining the existing\nInternet connectivity?\n\na. 255.255.252.0\nb. 255.255.255.252\nc. 255.255.255.248\nd. 255.255.248.0 "\n\nThe answer is 'd.' Quite frankly I do not understand what\nthe problem is getting at nor how 'd' gives the desired\nresults.\n\nAny explainations would be appreciated.
