Google Professional Cloud Network Engineer Question 92
Select 3Google Cloud PlatformYour organization is planning to deploy a global application on Google Cloud that requires low-latency connectivity for users across multiple continents. The application will have backend services hosted in multiple regions, and you need to ensure global load balancing, fault tolerance, and optimal traffic routing. Which Google Cloud networking components should you include in your design?
- A
Cloud Load Balancing with HTTP(S) Load Balancer
- B
Cloud VPN to connect users to Google Cloud regions
- C
Cloud CDN to cache content closer to users
- D
Global VPC to facilitate communication across regions
- E
Network Service Tiers set to Premium Tier
Show answer and explanation
Correct answers: A, C, E
Explanation
To design a global application requiring low-latency and fault tolerance, you need to use Cloud Load Balancing with HTTP(S) Load Balancer for global traffic distribution and fault tolerance. Cloud CDN reduces latency by caching content closer to users. Premium Tier ensures that traffic is routed through Google’s high-performance global network. Cloud VPN and Global VPC are not relevant for this use case.
- A. Correct.
Cloud Load Balancing with HTTP(S) Load Balancer is the correct choice for distributing traffic globally while maintaining fault tolerance and optimal routing. It supports backend services in multiple regions and provides a single anycast IP for global users.
- B. Incorrect.
Cloud VPN is used to securely connect on-premises networks to Google Cloud, but it is not directly applicable for global user connectivity or low-latency traffic routing.
- C. Correct.
Cloud CDN is an essential component for caching content closer to users, reducing latency and improving user experience for static assets.
- D. Incorrect.
Google Cloud does not currently support a true 'Global VPC.' Instead, you can use multiple regional VPCs, but this is not necessary for global load balancing or low-latency connectivity.
- E. Correct.
Network Service Tiers set to Premium Tier ensures that Google’s global private network is used for traffic, which improves performance and reduces latency for global applications.
