Google Professional Cloud Network Engineer Question 51
Single answerGoogle Cloud PlatformYour company is deploying a global web application hosted on Google Cloud, and you want to ensure the lowest latency for users worldwide while leveraging Google's private network for traffic between regions. However, budget constraints require you to minimize costs for data egress to the internet. Which network tier configuration should you choose?
- A
Use Premium Tier for both ingress and egress traffic.
- B
Use Standard Tier for both ingress and egress traffic.
- C
Use Premium Tier for ingress traffic and Standard Tier for egress traffic.
- D
Use Standard Tier for ingress traffic and Premium Tier for egress traffic.
Show answer and explanation
Correct answer: A
Explanation
Premium Tier is designed for applications requiring low-latency and high-performance connectivity, leveraging Google's private backbone network. It ensures optimal user experience for global applications. While Standard Tier is cost-effective, it uses the public internet, which may result in higher latency and is unsuitable for this use case. Mixing network tiers for ingress and egress traffic is not supported, so Premium Tier for both directions is the correct choice.
- A. Correct.
Correct: Premium Tier provides low-latency access for global users by utilizing Google's private backbone network for both ingress and egress traffic, ensuring optimal performance for a global application.
- B. Incorrect.
Incorrect: Standard Tier routes traffic over the public internet, which could lead to higher latency and inconsistent performance for global use cases.
- C. Incorrect.
Incorrect: Mixing Premium Tier for ingress and Standard Tier for egress is not supported. Network tiers must be consistent for both ingress and egress in a project.
- D. Incorrect.
Incorrect: Mixing Standard Tier for ingress and Premium Tier for egress is also not supported. Network tiers must be consistent for both traffic directions.
