Selected Answer: BCE

Likely Correct Answers: ✅ 1. Horizontal scaling (e.g., auto-scaling groups) Dynamically adds/removes servers based on demand Helps maintain uptime and fast response times under heavy load ✅ 2. Content Delivery Network (CDN) Distributes static content (images, scripts, etc.) closer to users globally Greatly improves load time and response time ✅ 3. Load balancing Distributes traffic evenly across multiple servers Reduces risk of single points of failure and improves availability and speed
