GCP Associate Cloud Engineer Practice Question 32: Committed Use Discount Baseline
Google Cloud Associate Cloud Engineer · Test 4 · question 2 of 10
A company runs a database on Compute Engine VMs of a fixed machine family and size. The VMs have run 24 hours a day for a year, and the workload will continue for at least the next three years. The company wants the largest discount without risking interruptions.
What should you purchase?
Show answer and explanation
Answer:
Committed use discounts (CUDs) trade a one or three year commitment to a level of resource usage for a lower price. For steady, predictable, 24/7 workloads, a three year commitment gives the deepest discount and the VMs are unaffected, so there is no interruption risk.
Option A is cheap, but Spot VMs can be preempted at any time, which is unsuitable for a database. Option B gives smaller discounts, and they are not available for every machine series. Option D helps you monitor costs but does not lower the price of anything.
