In the context of this material, which term describes the overall consideration of a medium based on cost, distance, and performance factors?

• A. Factors in media selection
• B. Network topology
• C. Data encapsulation
• D. Error correction codes

Answer: (A)

Media selection hinges on weighing cost, distance, and performance to decide which transmission medium to use. The best term here is “Factors in media selection” because it directly names the process of considering multiple criteria—budget, the needed reach, and performance requirements like bandwidth and latency—to choose the appropriate medium.

Understanding this helps you see why the other options don’t fit. Network topology describes how devices are arranged and connected, not how you evaluate and pick a medium. Data encapsulation is about adding headers and trailers to data for transmission, not selecting the delivery channel. Error correction codes are techniques to detect and fix errors in the transmitted data, which relates to reliability rather than the choice of medium.
