CV0-002 · Question #274
A cloud-based web store is experiencing poor website performance and unavailability. Which of the following approaches would prevent the issue without administrator intervention?
The correct answer is A. Install and deploy a load balancer in the front of the web server. To prevent poor website performance and unavailability without administrator intervention, deploying a load balancer is an effective approach that automatically distributes incoming traffic across multiple web servers.

Why each option
To prevent poor website performance and unavailability without administrator intervention, deploying a load balancer is an effective approach that automatically distributes incoming traffic across multiple web servers.
A load balancer automatically distributes incoming network traffic across a group of backend web servers, preventing any single server from becoming a bottleneck and ensuring high availability. By intelligently directing requests to healthy and available servers, it prevents performance degradation and service unavailability without requiring manual administrator intervention once configured.
Increasing computing resources to a single web server provides vertical scaling but does not prevent future performance issues if demand exceeds the new capacity or if that single server fails, and it usually requires intervention.
Increasing network bandwidth addresses only network-related bottlenecks and does not solve problems related to web server processing capacity or single points of failure that lead to unavailability.
Partnering with a cloud provider to scale resources is a strategic decision that enables elasticity, but the specific component that automatically distributes traffic and prevents issues for a web store is the load balancer.
