Google Cloud Professional Cloud DevOps Engineer — Question 84

You are configuring the frontend tier of an application deployed in Google Cloud. The frontend tier is hosted in nginx and deployed using a managed instance group with an Envoy-based external HTTP(S) load balancer in front. The application is deployed entirely within the europe-west2 region, and only serves users based in the United Kingdom. You need to choose the most cost-effective network tier and load balancing configuration. What should you use?

Answer options

• A. Premium Tier with a global load balancer
• B. Premium Tier with a regional load balancer
• C. Standard Tier with a global load balancer
• D. Standard Tier with a regional load balancer

Correct answer: D

Explanation

The correct choice is D, as using the Standard Tier with a regional load balancer is the most cost-effective solution for an application serving users solely in the UK from the europe-west2 region. Options A and C involve global load balancers, which are unnecessary and more expensive for a region-specific application, while option B uses a premium tier, which also incurs higher costs without additional benefits for this scenario.
