Practice Test 2 | Google Cloud Certified Professional Cloud DevOps Engineer | Dumps | Mock Test
A financial organization that analyses transactions carried out throughout the day at night. The analysis takes about three hours and must be run between midnight and 5am. The analysis is currently run on standard Compute Engine instances, with several OS level guardrails to satisfy government regulations, and can handle interruptions. You have been tasked with optimising the cost of the analysis which is to run for another six months.
Which of the following will optimise the cost?
A. Switch from the standard compute instances to preemptible instances
B. Switch from the standard compute instances to committed-use instances
C. Use the current set of instances because they are the cheapest.
D. Switch from the standard compute instances to Cloud Functions.
Corrcet Answer: A
- Option A is CORRECT. Preemptible instances provide the lowest cost and are excellent for batch processing.

- Option C is incorrect. The standard instance is the most expensive option.
- Option D is incorrect. This does not optimize the cost.
