3. C. Committed-Use
4. D. Sustained-Use
5. E. Preemptible VMs

Correct Answer: CDE
Sustained, Committed and Preemptible
vCPU and memory usage for each of these categories can receive discounts VM vCPU and memory usage for each of these categories can receive discounts
Sustained-use discounts—Google offers up to 30% off for workloads that run for most of the billing month on GCP services.
Committed-use discounts—users can save up to 57% by committing to use an instance for a certain time period, with no upfront payment and with the flexibility to change instances during the commitment period.
Preemptible VMs—similar to the concept of AWS spot instances, Google offers up to 79% off for Virtual Machines that may be shut down at any time and replaced by others.
