Routing tables contain a metric field that indicate the cost of a particular route. Which of the following could be possible parameters expressed in this field?
  1. Subnet mask
  2. Number of hops
  3. MAC address
  4. IP address
Explanation
Answer - B - The number of hops is the parameter that determines the cost of the route. IP address, MAC address, and subnet mask do not determine the cost of any route.

Key Takeaway: A cost of a route is obtained using an algorithm. This algorithm may use metrics like weight, local preference, aggregate, AS-path length, origin type, origin, and number of hops to calculate the cost of a route. Number of hops is the most primitive metric used by the RIP protocol.
