You’re called in to consult for a company that’s issuing about 100 new wireless mobile devices to selected employees. there are two subnets, each with a dhcp scope that has about 150 unused addresses and an access point that relays dhcp requests from wireless clients to the dhcp server. the mobile devices will be equally distributed between the subnets. both scopes are served by a dual-homed server. you want these mobile devices to be issued ip addresses, using the last 75 addresses of both scopes, and have a shorter lease time for addresses. what do you propose? what information do you need to carry out the proposal?
