Google Professional Cloud Network Engineer Question 1
Select 2Google Cloud PlatformYour organization is designing a distributed application that will span multiple Google Cloud regions. The application requires low-latency communication between services in different regions, high availability, and secure connectivity. Which of the following design decisions would best meet these requirements?
- A
Use Cloud Interconnect to establish a private connection between regions.
- B
Configure a Shared VPC and use VPC Network Peering for communication between regions.
- C
Implement a global external HTTP(S) Load Balancer with backends in multiple regions.
- D
Enable Private Google Access for secure communication between services in different regions.
- E
Use a single VPC with subnets in multiple regions and leverage Google Cloud's global network.
Show answer and explanation
Correct answers: C, E
Explanation
To meet the requirements of low latency, high availability, and secure connectivity for an inter-region application, the best design involves using Google Cloud's global infrastructure. A global external HTTP(S) Load Balancer ensures low-latency and highly available traffic distribution, while a single VPC with subnets across regions leverages Google's global network backbone for secure and efficient communication between regions.
- A. Incorrect.
Cloud Interconnect is used for private, high-bandwidth connections between on-premises networks and Google Cloud, not for inter-region communication within Google Cloud.
- B. Incorrect.
While VPC Network Peering can connect VPCs across regions, it is less efficient than leveraging Google Cloud's global network for inter-region communication within a single VPC.
- C. Correct.
A global external HTTP(S) Load Balancer provides low-latency, highly available, and secure communication by distributing traffic across multiple regions.
- D. Incorrect.
Private Google Access enables private communication to Google services from instances without public IPs but does not directly address inter-region communication requirements.
- E. Correct.
A single VPC with subnets in multiple regions allows you to use Google Cloud's global network backbone, ensuring low-latency and secure communication between regions.
