Explanation

{"question_number": 10, "question": "Five thousand employees access a cloud-hosted web application daily during the same time frame. Some users report performance issues. What is the best configuration approach?", "correct_answer": "B. Scale horizontally based on a schedule", "explanation": "Since 5,000 users connect during the same predictable daily time window, the load pattern is known in advance. Schedule-based scaling proactively adds capacity before the peak period begins, preventing performance issues rather than reacting after they occur. Horizontal scaling (adding more instances) is preferred for web applications because it distributes traffic across multiple nodes without a single point of failure. Vertical scaling (adding more CPU/RAM to one instance) has hardware limits and causes downtime during resizing. Event-based or load-based scaling is reactive-it responds after degradation is already occurring-whereas schedule-based scaling anticipates and prepares for the predictable daily surge.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
