Google Professional Cloud Developer Question 30
Select 2Google Cloud PlatformYou are designing a global application on Google Cloud that must minimize latency for users in different regions while adhering to compliance requirements for data residency. Which architectural decisions should you make to ensure the application meets both objectives?
- A
Deploy the application across multiple regions and use a global load balancer to route traffic to the nearest region.
- B
Store user data in a multi-region bucket for high availability and low latency.
- C
Use zonal services exclusively to reduce costs and improve latency for all regions.
- D
Leverage regional services to ensure compliance with data residency requirements.
- E
Use a single region deployment with a Content Delivery Network (CDN) to serve static content globally.
Show answer and explanation
Correct answers: A, D
Explanation
To minimize latency for users across different regions, you need to deploy your application across multiple regions and use a global load balancer to direct traffic to the closest region. At the same time, to meet compliance requirements for data residency, regional services must be used to store and process data in specific regions. Combining these approaches ensures the application meets both objectives effectively.
- A. Correct.
Deploying the application across multiple regions and using a global load balancer ensures low latency for users by routing their traffic to the nearest region, addressing the latency requirement.
- B. Incorrect.
Storing user data in a multi-region bucket improves availability and durability but doesn't address data residency compliance, which often requires data to remain within a specific geographic location.
- C. Incorrect.
Zonal services are limited to a single zone and aren't suitable for minimizing latency across multiple regions. They also don't support regional or global data residency compliance.
- D. Correct.
Leveraging regional services ensures compliance with data residency requirements, as these services allow you to specify the region where data is stored and processed.
- E. Incorrect.
Using a single region deployment with a CDN improves global access to static content but does not address latency for dynamic content or ensure data residency compliance for users in different regions.
