CASE STUDY: TechStream Gaming Overview: Gaming company, 500 employees, $100M revenue. 200 on-prem servers (US/EU), MySQL 5TB. 2M peak users. $150K/mo cost. Business Req: Reduce cost 40%, 5x growth, 3 new regions, daily deployments. Execs: CEO wants scale; CFO caps budget at $100K/mo; CTO needs 99.95% uptime, notes team has limited cloud skills. Tech Req: <100ms global latency, real-time analytics, 5x seasonal spikes, EU data residency, DDoS protection. Constraints: 12-month migration, max 4-hour downtime. QUESTION: To meet the requirement for <100ms global latency and DDoS protection, which networking solution should you implement?

Your organization has 10 different departments, each with their own GCP project. The central IT security team wants to manage all firewall rules and subnets centrally, while allowing the departments to create their own VMs. Which networking feature should you use?

You are designing the hybrid connectivity between your on-premises data center and GCP. The connection must support 20 Gbps of throughput, must not traverse the public internet, and requires an industry-standard SLA of 99.99%. Which TWO components are required to achieve this? (Select TWO)
