Your customer has a reporting tool that is only occasionally used by the leadership team. Usage of it is frequent - once a week, once a month, or once the quarter. They want to run this application in a cost-effective manner. What are the compute options available on Google Cloud which would be suitable? (Choose Two answer)

1. A. Cloud Run
2. B. Cloud App Engine Standard
3. C. Compute Engine
4. D. Kubernetes Engine

Correct Answer: AB
Since the use of the tool is infrequent/intermittent, you can choose to compute options that are serverless. Both Cloud Run and Cloud App Engine Standard are serverless options that can shut down to zero. Since
cost-effectiveness is a requirement, this will not cost anything during the periods it is not used.
