Which three of the following cost factors might least-cost routing use to calculate a minimum-cost path for a packet? (Choose three.)

The three cost factors that least-cost routing might use to calculate a minimum-cost path for a packet are:

A. Bandwidth

B. Delay

D. Cash costs

Explanation:

– Bandwidth: This factor considers the capacity of the link, affecting the cost of transmission. Higher bandwidth generally leads to lower transmission time and costs.

– Delay: This reflects the time it takes for a packet to traverse the network. Lower delay typically equates to a more efficient (and therefore cheaper) path.

– Cash costs: This refers to the monetary cost associated with using a particular route or link, which is a primary consideration in least-cost routing.

Router load (C) is less about cost and more about performance and congestion, thus it’s not typically a direct factor in calculating least-cost paths. If you have any further questions or need more detailed assistance, consider checking out our extended services page!
