functional or message acknowledgements
In an e-commerce environment, the risk of communication failure is best minimized by using functional or message acknowledgments because: They confirm receipt of messages between systems, ensuring that data was successfully transmitted and received. If an acknowledgment is not received, the sender can retry sending or take corrective actions, minimizing the risk of lost or incomplete communication. This mechanism is essential for reliable, end-to-end communication, especially in transactional environments like e-commerce. Why not the others? A. Alternative or diverse routing ➤ Helps improve network availability but does not guarantee message receipt or confirmation. B. Compression software to minimize transmission duration ➤ Improves efficiency but doesn’t address communication failure or message loss. D. A packet filtering firewall to reroute messages ➤ Firewalls control traffic flow for security, not for rerouting or guaranteeing delivery.
