To reduce costs, the Director of Engineering has required all developers to move their development infrastructure resources from on-premises virtual machines (VMs) to Google Cloud Platform. These resources go through multiple start/stop events during the day and require state to persist. You have been asked to design the process of running a development environment in Google Cloud while providing cost visibility to the finance department. Which two steps should you take? Choose 2 answers.
Correct Answer: C,E
Explanation/Reference: Explanation: C: Billing export to BigQuery enables you to export your daily usage and cost estimates automatically throughout the day to a BigQuery dataset you specify. Labels applied to resources that generate usage metrics are forwarded to the billing system so that you can break down your billing charges based upon label criteria. For example, the Compute Engine service reports metrics on VM instances. If you deploy a project with 2,000 VMs, each of which is labeled distinctly, then only the first 1,000 label maps seen within the 1 hour window will be preserved. E: You cannot stop an instance that has a local SSD attached. Instead, you must migrate your critical data off of the local SSD to a persistent disk or to another instance before you delete the instance completely. You can stop an instance temporarily so you can come back to it at a later time. A stopped instance does not incur charges, but all of the resources that are attached to the instance will still be charged. Alternatively, if you are done using an instance, delete the instance and its resources to stop incurring charges.

this question is in the official practice exam from google (05-06-2019) they say: Use persistent disks to store the state. Start and stop the VM as needed.
B. Use the --auto-delete flag on all persistent disks before stopping the VM. C. Apply VM CPU utilization label and include it in the BigQuery billing export.
D. Use BigQuery billing export and labels to relate cost to groups. E. Store all state in local SSD, snapshot the persistent disks, and terminate the VM. F. Store all state in Cloud Storage, snapshot the persistent disks, and terminate the VM.
Correct answer A. Use persistent disks to store the state. Start and stop the VM as needed. D. Use BigQuery billing export and labels to relate cost to groups. Feedback A is correct because persistent disks will not be deleted when an instance is stopped. B is not correct because the --auto-delete flag has no effect unless the instance is deleted. Stopping an instance does not delete the instance or the attached persistent disks.
C is not correct because labels are used to organize instances, not to monitor metrics.
D is correct because exporting daily usage and cost estimates automatically throughout the day to a BigQuery dataset is a good way of providing visibility to the finance department. Labels can then be used to group the costs based on team or cost center.
E is not correct because the state stored in local SSDs will be lost when the instance is stopped.
F is not correct because there is no need for persistent disks or snapshots if the state is to be stored in Cloud Storage.
