Answer: Leverage Network Service Tiers for different traffic priorities, Utilize managed instance groups with autoscaling

**Correct Answers:** - **Leverage Network Service Tiers for different traffic priorities:** Google Cloud offers Premium and Standard tiers. Premium ensures high performance and availability, while Standard reduces costs for less critical workloads, optimizing network pricing and resource use. - **Utilize managed instance groups with autoscaling:** Autoscaling adjusts instance numbers based on demand, preventing over-provisioning and minimizing costs. **Incorrect Options:** - **Deploy all resources in a single region:** This approach increases latency for distant users and creates a single point of failure, reducing resilience. - **Manually provision a fixed number of instances:** Fixed provisioning can lead to resource under or over-utilization, lacking the flexibility to adapt to demand changes. - **Use Cloud Interconnect for traffic between on-premises and GCP:** While beneficial for secure, low-latency connections between on-premises and GCP, it doesn't directly optimize internal GCP resource utilization or network pricing.
