Google Cloud Professional Cloud Architect — Question 17

The current Dress4Win system architecture has high latency to some customers because it is located in one data center.
As of a future evaluation and optimizing for performance in the cloud, Dresss4Win wants to distribute its system architecture to multiple locations when Google cloud platform.
Which approach should they use?

Answer options

• A. Use regional managed instance groups and a global load balancer to increase performance because the regional managed instance group can grow instances in each region separately based on traffic.
• B. Use a global load balancer with a set of virtual machines that forward the requests to a closer group of virtual machines managed by your operations team.
• C. Use regional managed instance groups and a global load balancer to increase reliability by providing automatic failover between zones in different regions.
• D. Use a global load balancer with a set of virtual machines that forward the requests to a closer group of virtual machines as part of a separate managed instance groups.

Correct answer: A

Explanation

The correct answer is A because using regional managed instance groups with a global load balancer allows the system to scale resources based on localized demand, effectively reducing latency for users. Option B lacks the scalability aspect, while C focuses on reliability rather than performance. Option D also misses the important performance optimization provided by regional managed instance groups.
