Google Cloud Associate Cloud Engineer — Question 209

You want to host your video encoding software on Compute Engine. Your user base is growing rapidly, and users need to be able 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?

Answer options

• A. Deploy your solution on multiple standalone Compute Engine instances, and increase the number of existing instances when CPU utilization on Cloud Monitoring reaches a certain threshold.
• B. Deploy 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.
• C. Deploy your solution to an instance group, and increase the number of available instances whenever you see high CPU utilization in Cloud Monitoring.
• D. Deploy your solution to an instance group, and set the autoscaling based on CPU utilization.

Correct answer: D

Explanation

The correct answer is D because deploying the solution to an instance group with autoscaling allows for automatic adjustment of the number of instances based on real-time CPU utilization, ensuring high availability and efficient resource use. Options A and B rely on manual scaling and do not utilize the benefits of instance groups or automation, while option C lacks the specific requirement of setting up autoscaling.
