CompTIA A+ Core 1 (220-1101) — Question 248

An online retailer is working to support increased sales and boost server capacity by installing additional servers. Which of the following should be used to ensure each new server will be properly utilized?

Answer options

• A. Virtualization
• B. DNS
• C. Clustering
• D. Load balancer

Correct answer: D

Explanation

The correct answer is D, Load balancer, as it distributes incoming network traffic across multiple servers to ensure no single server becomes overwhelmed. Virtualization (A) allows multiple virtual servers on a single physical server but does not manage traffic. DNS (B) is used for resolving domain names and does not handle server load, and Clustering (C) helps with redundancy but does not manage the distribution of incoming traffic.
