[All Google Associate Cloud Engineer Questions]

You want to host your video encoding software on Compute Engine. Your user base is growing rapidly, and users need to be able 3 to encode their videos at any time without interruption or CPU limitations. You must ensure that your encoding solution is highly available, and you want to follow Google-recommended practices to automate operations. What should you do?

ADeploy your solution on multiple standalone Compute Engine instances, and increase the number of existing instances wnen CPU utilization on Cloud Monitoring reaches a certain threshold.

BDeploy your solution on multiple standalone Compute Engine instances, and replace existing instances with high-CPU
instances when CPU utilization on Cloud Monitoring reaches a certain threshold.

CDeploy your solution to an instance group, and increase the number of available instances whenever you see high CPU utilization in Cloud Monitoring.

DDeploy your solution to an instance group, and set the autoscaling based on CPU utilization.

Show Suggested Answer

Suggested Answer: D

Instance groups are collections of virtual machine (VM) instances that you can manage as a single entity. Instance groups can help you simplify the management of multiple instances, reduce operational costs, and improve the availability and performance of your applications. Instance groups support autoscaling, which automatically adds or removes instances from the group based on increases or decreases in load. Autoscaling helps your applications gracefully handle increases in traffic and reduces cost when the need for resources is lower. You can set the autoscaling policy based on CPU utilization, load balancing capacity, Cloud Monitoring metrics, or a queue-based workload. In this case, since the video encoding software is CPU-intensive, setting the autoscaling based on CPU utilization is the best option to ensure high availability and optimal performance.Reference:

I think option D is the best choice. Autoscaling based on CPU utilization will ensure that our encoding solution is highly available and can handle the growing user base.
