Certified Information Systems Auditor (CISA) — Question 230

Which of the following approaches would BEST enable an e-commerce website to handle unpredictable amounts of traffic?

Answer options

• A. Index key databases to improve response time.
• B. Re-factor applications to improve efficiency.
• C. Cluster application servers to distribute web traffic.
• D. Configure resources to scale.

Correct answer: C

Explanation

Clustering application servers allows for the distribution of web traffic across multiple servers, ensuring that no single server becomes overwhelmed during traffic spikes. The other options, while beneficial for performance and efficiency, do not directly address the need to manage unpredictable traffic levels as effectively as clustering does.
