Google Professional Cloud Network Engineer Question 54
Select 1Google Cloud PlatformYour company has a global web application hosted on Google Cloud. You want to ensure users experience the lowest latency possible by leveraging Google's global network infrastructure for traffic routing. However, cost control is also essential for regional workloads where latency is less critical. Which network tier(s) should you use to meet these requirements?
- A
Use the Premium Tier for all traffic to ensure optimal performance globally.
- B
Use the Standard Tier for all traffic to minimize costs.
- C
Use the Premium Tier for latency-sensitive traffic and the Standard Tier for regional traffic.
- D
Use the Standard Tier for traffic originating from regions outside of Google's global network infrastructure.
Show answer and explanation
Correct answer: C
Explanation
The requirement is to ensure low latency for global users while controlling costs for regional workloads. The Premium Tier leverages Google's global network infrastructure for optimal performance, making it suitable for latency-sensitive traffic. The Standard Tier routes traffic through public internet paths, reducing costs and making it suitable for regional traffic where latency is less critical. Using both tiers appropriately fulfills the requirements.
- A. Incorrect.
This option ensures optimal performance globally but does not address cost control for non-latency-critical regional workloads. While it provides the best performance, it does not meet the requirement of balancing performance and cost.
- B. Incorrect.
This option minimizes costs but does not leverage Google's global network infrastructure to provide low latency for the global user base. It fails to meet the performance requirement.
- C. Correct.
This option balances the use of the Premium Tier for latency-sensitive global traffic and the Standard Tier for regional traffic, meeting both the performance and cost requirements.
- D. Incorrect.
This option is incorrect because Google’s global network infrastructure is still utilized in most regions, and the Standard Tier does not selectively avoid Google's global network. Traffic routing is based on the tier chosen and not the region.
