A networks uses only RIP v1 as the routing protocol. What is the maximum number of usable IP addresses that can be supported on each LAN if one Class C address block is used?
  1. 30
  2. 32
  3. 62
  4. 14
Explanation
Answer - C - A maximum of 62 IP addresses can be supported on each LAN.

Key Takeaway: Since this network setup uses RIP v1, VLSM cannot be used. The setup has a total of 8 networks, with 4 LANs and 4 point-to-point WAN connections. Hence, a subnet mask of 255.255.255.224 should be used. This will account for a total of 8 networks, with each network supporting 30 IP addresses.
