Google Professional Cloud Network Engineer Question 120
Single answerGoogle Cloud PlatformYour organization operates workloads in both Google Cloud and AWS. You need to establish secure and high-performance connectivity between the two clouds for real-time data replication. The connectivity solution should minimize latency, provide predictable performance, and meet enterprise-grade security requirements. Which solution would best meet these requirements?
- A
Set up a Cloud VPN tunnel between Google Cloud and AWS.
- B
Use a Cross-Cloud Interconnect to establish a dedicated link between Google Cloud and AWS.
- C
Leverage a third-party VPN solution to create a secure connection between Google Cloud and AWS.
- D
Set up a public-facing endpoint on both clouds and use HTTPS for secure communication.
Show answer and explanation
Correct answer: B
Explanation
Cross-Cloud Interconnect is the most suitable solution for establishing secure, high-performance connectivity across Google Cloud and AWS. It provides dedicated links that minimize latency and ensure predictable throughput, making it ideal for real-time data replication scenarios. Other options, such as VPNs or public endpoints, do not fulfill all the requirements for enterprise-grade performance and security.
- A. Incorrect.
Cloud VPN is a secure option but does not provide the low-latency and predictable performance needed for real-time data replication. It relies on the public internet, which can introduce variability.
- B. Correct.
Cross-Cloud Interconnect is the ideal choice as it offers dedicated, high-performance connectivity with low latency and predictable bandwidth, meeting both latency and security requirements.
- C. Incorrect.
While a third-party VPN solution may provide security, it would still be dependent on the public internet, leading to variable performance and increased latency.
- D. Incorrect.
Using public-facing endpoints with HTTPS ensures security but does not meet the requirements for low latency and predictable performance. Additionally, exposing public endpoints can increase the attack surface.
