Exam Professional Cloud Developer topic 1 question 144 discussion

correct answer A

"handle traffic spikes efficiently" Cloud run the fastest to autoscale among the given options. GKE could be considered too, but Cloud Run s cheaper

Cloud Run is the cheapest solution among these options and can scale up and down to 0 instances.

Google Kubernetes Engine (GKE) is a managed Kubernetes service that allows you to deploy and run containerized applications. GKE is a good choice for running a single-player mobile game backend because it can be easily scaled up or down to meet the needs of your game. Cloud Run is a serverless computing platform that allows you to run code without managing servers. Cloud Run is a good choice for running simple applications, but it is not as scalable as GKE.

I go with A. The requirement is to optimize the cost while scaling for unexpected spikes in the traffic. Cloud Run is the cheapest among all the other options given.

Bing chose D: For a single-player mobile game backend with unpredictable traffic patterns and a need to optimize costs while handling traffic spikes efficiently, Google Kubernetes Engine (GKE) using cluster autoscaling (option D) would be a good choice. GKE’s cluster autoscaler automatically resizes the number of nodes in a node pool based on the demands of your workloads. This helps ensure that you have enough resources to handle requests while minimizing over-provisioning and optimizing costs.

Answer A

Compute Engine answers are eliminated because they can't scale quickly enough. GKE Answer is ruled out because you can end up overprovisioned, also cannot scale out to add more nodes quickly enough.

A is the answer.

vote D

Answer is D to lessen the over-provisioning Not A - the app is not containerized Not sure with Compute Engine https://cloud.google.com/blog/products/containers-kubernetes/gke-best-practices-to-lessen-over-provisioning
