Question

You work as an architect in a company that develops statistical studies on big data and produces reports for its customers. Analysts often allocate VMs to process data with ad hoc development procedures. You have been called by the administrative department because they have been billed for a very large number of Compute Engine instances, which you also consider excessive in relation to operational needs. How can you check, without controlling them one by one, which of these systems can be accidentally left active by junior technicians?

Options

  • AUse the Recommender CLI Command
  • BUse Cloud Billing Reports
  • CUse Idle Systems Report in GCP Console
  • DUse Security Command Center Reports

Explanation

gcloud recommender recommendations list -recommender = google.compute.instance.IdleResourceRecommender gives to all the idle VMs based on Cloud Monitoring metrics of the previous 14 days. There is no equivalent in the Console. B is wrong because Cloud Billing Reports don’t give details about activities. C is wrong because there is no Idle Systems Report in the GCP Console. D is wrong because the Security Command Center is used for Security threats, not for ordinary technical operations.
