Google Professional Cloud Network Engineer Question 95
Select 3Google Cloud PlatformYou are designing a global network for a multinational organization that has users across North America, Europe, and Asia. The organization needs low-latency access to its cloud-hosted applications, and the solution must be highly available and resilient to regional failures. Which combination of Google Cloud services and configurations would best meet these requirements?
- A
Use Cloud Load Balancing with a global external HTTP(S) load balancer to distribute traffic across multiple regions.
- B
Deploy Virtual Private Cloud (VPC) networks in each region and interconnect them using Cloud VPN.
- C
Enable Cloud CDN to cache content at edge locations closest to users.
- D
Deploy a single regional VPC network in one region and route all traffic through it.
- E
Use Cloud Interconnect to establish private connectivity between on-premises data centers and Google Cloud.
Show answer and explanation
Correct answers: A, C, E
Explanation
To meet the requirements of low-latency, high availability, and resilience across multiple regions, combining Cloud Load Balancing, Cloud CDN, and Cloud Interconnect is the best approach. Cloud Load Balancing ensures global traffic distribution and resilience, while Cloud CDN reduces latency by caching content near users. Cloud Interconnect provides private, high-performance connectivity for hybrid setups. Cloud VPN and a single regional VPC are not suitable for this scenario due to scalability and performance limitations.
- A. Correct.
Cloud Load Balancing with a global external HTTP(S) load balancer provides low-latency traffic distribution across multiple regions while ensuring high availability and resilience to regional failures.
- B. Incorrect.
While Cloud VPN can connect VPCs in different regions, it is not optimal for low-latency global traffic distribution or resilience at scale compared to other solutions like Cloud Load Balancing.
- C. Correct.
Cloud CDN caches content at edge locations, reducing latency for end users by serving content closer to their geographic location.
- D. Incorrect.
A single regional VPC network in one region would not meet the requirements for a global, low-latency, and resilient solution, as it centralizes traffic in one region.
- E. Correct.
Cloud Interconnect provides private connectivity between on-premises data centers and Google Cloud, which can improve performance and reduce latency for hybrid environments.
