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

Least cost routing is a technique used in telecommunication and networking that selects the path for data transmission based on cost-effectiveness. When determining the minimum-cost path, various factors can be considered, and in this case, the chosen option includes bandwidth, delay, and cash costs, which are all critical in calculating routing costs.

Bandwidth refers to the data transfer capacity of a link, which can affect the performance and thus the cost of transmitting data. Higher bandwidth paths may be preferred when cost is measured not just in monetary terms but in the efficiency and speed of data transfer.

Delay is the time taken for a packet of data to travel from the source to the destination. Minimizing delay can reduce overall costs related to the time taken for communication, making paths with lower latency more desirable.

Cash costs refer to the actual monetary expense associated with using a particular path, which can include fees, taxes, or other financial considerations. Choosing paths with lower cash costs directly impacts the total expenditure of data transmission.

The other choices provide factors that may be useful but do not directly align as closely with the standard metrics used in least cost routing computations. For example, while reliability and distance are important, they do not always translate directly into computational cost metrics as effectively as bandwidth, delay
