Question 44/70

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

A. Store all state in Google Cloud Storage, snapshot the persistent disks, and terminate the VM.

B. Use the --no-auto-delete flag on all persistent disks and stop the VM.

C. Apply VM CPU utilization label and include it in the BigQuery billing export.

D. Use Google BigQuery billing export and labels to associate cost to groups.

E. Use the -auto-delete flag on all persistent disks and terminate the VM.

F. Store all state into local SSD, snapshot the persistent disks, and terminate the VM.

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.

B can't be right. According to https://cloud.google.com/compute/docs/instances/stopping-or-deleting-an-instance "A TERMINATED instance still exists with its configuration settings and instance metadata but loses its in-memory data and virtual machine state.". But the question states "require state to persist". So you have to first store the state information. As local SSDs are quite expensive, why not storing the state in GCS? Plus you cannot stop an instance that has a local SSD attached.

Therefore I opt for A and D

Any articles where I can read about it?
