Certified Information Systems Auditor (CISA) — Question 1165

Which of the following BEST reduces the risk of a network transmission failure?

Answer options

• A. Compression software to minimize transmission duration
• B. Server load balancing
• C. A packet filtering firewall to reroute messages
• D. Alternative or diverse routing

Correct answer: D

Explanation

D is correct because using alternative or diverse routing ensures that if one path fails, another can be used, thus maintaining network reliability. A, B, and C may improve performance or security but do not directly address the risk of transmission failure.
