Multiple choice

Refer to the exhibit. What is the significance of the /8 in the route to the 10.0.0.0 network?

  1. It indicates that there are 8 hops between this and the 10.0.0.0 network.

  2. It represents the time, in milliseconds, it takes for a ping to reply when sent to the 10.0.0.0 network.

  3. It indicates that there are 8 subnets in the destination network to which the router can forward packets.

  4. It indicates the number of consecutive bits, from the left, in the destination IP address of a packet that must match 10.0.0.0 to use that route.

D Correct answer
Explanation

CIDR notation /8 indicates a subnet mask of 255.0.0.0, meaning the first 8 bits (first octet) of the destination IP must match 10.x.x.x for this route to be used. This is the prefix length - it tells the router how many bits, starting from the left, must match the network address. The remaining bits can vary for individual host addresses within that network.
