Certified Information Systems Auditor (CISA) — Question 271

The risk of communication failure in an e-commerce environment is BEST minimized through the use of:

Answer options

• A. alternative or diverse routing.
• B. compression software to minimize transmission duration.
• C. functional or message acknowledgments.
• D. a packet filtering firewall to reroute messages

Correct answer: A

Explanation

Using alternative or diverse routing provides multiple pathways for data transmission, which effectively mitigates the risk of communication failures. In contrast, compression software mainly focuses on reducing data size and transmission time, while functional acknowledgments confirm receipt but do not prevent failures. A packet filtering firewall is designed for security, not specifically for minimizing communication failures.
