Google Professional Data Engineer Question 76
Single answerGoogle Cloud PlatformYou are designing a data processing system on Google Cloud Platform (GCP) that requires secure communication between Compute Engine instances in different VPC networks. The networks are in separate projects but need to communicate with minimal latency. Which GCP networking feature should you use to enable secure and efficient communication between the instances?
- A
VPC Network Peering
- B
Cloud VPN
- C
Cloud Interconnect
- D
Private Google Access
Show answer and explanation
Correct answer: A
Explanation
VPC Network Peering is the appropriate solution for enabling secure and efficient communication between Compute Engine instances in separate VPC networks. It facilitates private connectivity without relying on the public internet, ensuring low latency and high throughput. Other options, such as Cloud VPN and Cloud Interconnect, are designed for different use cases and do not align with the requirements described in this scenario.
- A. Correct.
VPC Network Peering allows private communication between resources in different VPC networks across projects and regions, with minimal latency and no reliance on public internet. It is the best choice for this scenario.
- B. Incorrect.
Cloud VPN provides encrypted communication over the internet between on-premises and GCP or between different VPC networks. However, it introduces additional latency due to encryption and routing through the internet, which is not ideal for this use case.
- C. Incorrect.
Cloud Interconnect is used for high-bandwidth and low-latency connections between on-premises data centers and GCP. It is not applicable for communication between two GCP VPC networks.
- D. Incorrect.
Private Google Access allows private communication from on-premises or non-Google Cloud environments to Google APIs and services. It is not relevant for communication between VPC networks.
