A cloud-based web store is experiencing poor website performance and unavailability. Which of the following approaches would prevent the issue without administrator intervention?

A load balancer placed in front of the web server tier continuously and automatically routes incoming requests across available servers based on health and load, eliminating single-server bottlenecks and improving both availability and performance without requiring an administrator to manually intervene during a traffic spike.

Increasing computing resources is a manual action performed by an administrator and does not represent an automated or self-correcting solution.

Increasing network bandwidth is a manual configuration change by an administrator and does not address server-side processing limitations causing poor performance.

Partnering with a cloud provider to scale resources describes a business arrangement or auto-scaling agreement, not a specific technical component that prevents the issue autonomously in real time.
