Google Professional Cloud Network Engineer Question 91
Select 2Google Cloud PlatformYour organization is planning to expand its services globally and needs to design a highly available and low-latency network. The services will be deployed across multiple continents, and the organization wants to use Google Cloud to ensure optimal performance and fault tolerance. Which of the following design choices should you implement to meet these requirements?
- A
Leverage Cloud Load Balancing with a global external HTTP(S) load balancer.
- B
Use Virtual Private Cloud (VPC) networks with regional subnets only to ensure better control over resources.
- C
Enable Cloud CDN to cache content closer to users in different geographic locations.
- D
Configure Cloud Interconnect for private connectivity between on-premises data centers and Google Cloud.
- E
Deploy a single Compute Engine instance in one region to handle global traffic.
Show answer and explanation
Correct answers: A, C
Explanation
To design a global and highly available network environment, it is essential to use a global load balancer to route traffic optimally based on user location and backend health. Additionally, enabling Cloud CDN ensures that static content is served from edge locations closer to users, reducing latency and improving performance. These features together provide a robust, scalable, and low-latency solution for global users.
- A. Correct.
Leverage Cloud Load Balancing with a global external HTTP(S) load balancer: Correct. A global external HTTP(S) load balancer provides a single anycast IP and routes traffic to the nearest backend, ensuring low latency and high availability for users worldwide.
- B. Incorrect.
Use Virtual Private Cloud (VPC) networks with regional subnets only to ensure better control over resources: Incorrect. While regional subnets provide granular control, they do not inherently improve global availability or latency. A global solution like Cloud Load Balancing is required for this use case.
- C. Correct.
Enable Cloud CDN to cache content closer to users in different geographic locations: Correct. Cloud CDN reduces latency by serving cached content from Google's globally distributed edge locations, improving performance for users worldwide.
- D. Incorrect.
Configure Cloud Interconnect for private connectivity between on-premises data centers and Google Cloud: Incorrect. While useful for hybrid connectivity, Cloud Interconnect does not directly address global availability or latency for public-facing services.
- E. Incorrect.
Deploy a single Compute Engine instance in one region to handle global traffic: Incorrect. A single instance in one region is a single point of failure and does not provide the scalability or low latency needed for a global deployment.
