    24. A network administrator must use the subnet to create 6 additional subnets each containing up to 2000 hosts for local LANs. Which subnet mask should the administrator use to create the new subnets?
    25. When connecting two devices, which situation would normally require the use of a crossover cable?
    connecting a host to a router console port
    26. Which router mode is accessed by entering the enable command?
