Melinda is a new network consultant and is supporting a network for a business. Melinda finds that the client uses subnetting due to a large number of hosts. All hosts have a subnet mask of 255.255.255.192. Melinda is trying to get a host with an IP address of 192.168.2.193 to communicate with a host at IP address of 192.168.2.246. Both hosts are already on the same switch. What additional device will Melinda need to route the traffic between these two hosts?
  1. A network bridge
  2. A circuit-level gateway
  3. A network router
  4. None. These addresses are on the same logical network.
Explanation
Answer: D - No device is needed to route traffic as both of these devices are on the same network.

Key Takeaway: With the subnet mask of 255.255.255.192, every device with an address whose last octet is higher than 192 is on the same logical network. The system is including the first two bits of the last octet as a part of the network address. In this example every device with an IP address from 192.168.2.193 to 192.168.2.254 would be on the same network.
