Practice Test 1 | Google Cloud Certified Professional Cloud Architect | Dumps | Mock Test
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? (Select TWO)
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 terminate 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.
Correct answers: B and D
B (Correct Answer) – Use the –no-auto-delete flag on all persistent disks and terminate the VM – with this flag set, when you terminate the instance, the persistence disk will not be deleted so the disk contents are preserved between the start and terminate. When the instance is in stop status, you are only getting charged for very low-cost disk storage
auto-delete for the given disk is enabled by default, use –no-auto-delete to disable it.

C – Apply VM CPU utilization label and include it in the BigQuery billing export – this is simply not doable
D (Correct Answer) – Use Google BigQuery billing export and labels to associate cost to groups.
Billing export to BigQuery enables you to export your daily usage and cost estimates automatically throughout the day to a BigQuery dataset you specify. You can then access your billing data from BigQuery.
About labels: You’ll see columns for labels in your BigQuery dataset, but for the current release, some label values will be empty. Label export data will be populated at different times for different services, depending on when each service provides it.
E – Use the -auto-delete flag on all persistent disks and terminate the VM – This is totally against the requirements. Since the instance is terminated and the disk is gone when this flag is on, there is no way to restart the same instance, and needless to say, the disk content is not persisted.
Answer A and F are incorrect, or at least not as good as Answer B – they are not a suitable solution for frequent start/stop and require the state to persist.
