I need some help with the following subnet problem: "You are the new administrator of a 2000 node network. There is only one router on the entire network, which provides all the computers with Internet access. The company's ISP has assigned the following 8 network addresses to them: 10.24.32.0/24 10.24.33.0/24 10.24.34.0/24 10.30.35.0/24 10.30.36.0/24 10.30.37.0/24 10.30.38.0/24 10.30.39.9/24 What subnet mask could you use to minimize the complexity of the routing tables while maintaining the existing Internet connectivity? a. 255.255.252.0 b. 255.255.255.252 c. 255.255.255.248 d. 255.255.248.0 " The answer is 'd.' Quite frankly I do not understand what the problem is getting at nor how 'd' gives the desired results. Any explainations would be appreciated.
