CompTIA A+ Core 1 (220-1101) — Question 504

An online retailer would like to add capacity to support increased sales. Additional servers have been installed. Which of the following should be used to ensure each new server is being properly utilized?

Answer options

• A. Virtualization
• B. Clustering
• C. Load balancer
• D. Round-robin DNS

Correct answer: C

Explanation

The correct answer is C, as a load balancer distributes incoming traffic across multiple servers, ensuring that each server is used efficiently and preventing any single server from becoming overwhelmed. Virtualization (A) and clustering (B) are useful for resource management but do not directly manage traffic distribution like a load balancer does. Round-robin DNS (D) can distribute requests but lacks the intelligent load management features of a dedicated load balancer.
