Q: CASE STUDY: TechStream Gaming Overview: 500 employees, $100M revenue. On-prem US/EU, 200 servers, 5TB MySQL. 2M peak users, $100K/mo cost. Business: Reduce cost 40%, 5x growth, launch APAC/SA/Africa, daily deployments. Executives: - CEO: "Scale rapidly to compete. Cloud is critical." - CFO: "Cost reduction paramount. Max $100K/mo. ROI in 18 months." - CTO: "Team has limited cloud experience. 99.95% uptime non-negotiable." Tech: <100ms latency globally, real-time analytics, 5x seasonal spikes, EU data residency, DDoS protection, CI/CD. Constraints: 12-month migration, 4hr max downtime, 20 devs (Java/MySQL), 5 ops (limited cloud), $2M budget. Which migration strategy should you recommend for the core gaming application to meet the business and technical requirements?

Analyze the constraints (12 months, Java skills) against the goals (global scale, daily deployments). Replatforming strikes the right balance.

Q: What mistakes do candidates make on this GCP PCA question?

Choosing Lift and Shift (A) ignores the need for modernization (daily deployments, 5x scale). Choosing Rewrite (C) ignores the 12-month timeline constraint.
