Google Professional Cloud Network Engineer Question 93
Select 2Google Cloud PlatformYour company is planning to deploy a global application that serves users from multiple continents. The application is hosted in multiple Google Cloud regions. To optimize performance and reliability, you need to design the network architecture. Which two steps should you take when planning this global network environment?
- A
Use a global external HTTPS load balancer to distribute traffic across multiple regions.
- B
Rely on a single regional VPC network for all workloads to simplify the architecture.
- C
Enable Cloud CDN to reduce latency for end-users accessing static content.
- D
Create separate VPC networks for each region to ensure network isolation.
Show answer and explanation
Correct answers: A, C
Explanation
When planning a global network environment for a multi-region application, you should utilize global networking features like the global external HTTPS load balancer and Cloud CDN to optimize performance and reliability. These tools leverage Google's global network infrastructure, providing low latency and high availability. Avoid overly regionalized or isolated designs, as they can hinder scalability and increase complexity.
- A. Correct.
Correct: A global external HTTPS load balancer allows you to distribute traffic across multiple regions, ensuring high availability and low latency for users worldwide.
- B. Incorrect.
Incorrect: Using a single regional VPC network for all workloads limits scalability and performance for a global application, as it does not take advantage of Google Cloud's global network infrastructure.
- C. Correct.
Correct: Cloud CDN caches content at the edge, reducing latency and improving performance for end-users accessing static assets globally.
- D. Incorrect.
Incorrect: Creating separate VPC networks for each region can complicate the architecture and make network management and inter-region communication more difficult. A shared VPC or a global network design is often preferred for global applications.
