Actual exam question from Google's Cloud Digital Leader

Question #: 8
Topic #: 1

You are a program manager within a Software as a Service (SaaS) company that offers rendering software for animation studios. Your team needs the ability to allow scenes to be scheduled at will and to be interrupted at any time to restart later. Any individual scene rendering takes less than 12 hours to complete, and there is no service-level agreement (SLA) for the completion time for all scenes. Results will be stored in a global Cloud Storage bucket. The compute resources are not bound to any single geographical location. This software needs to run on Google Cloud in a cost-optimized way.
What should you do?

A. Deploy the application on Compute Engine using preemptible instances
B. Develop the application so it can run in an unmanaged instance group
C. Create a reservation for the minimum number of Compute Engine instances you will use
D. Start more instances with fewer virtual centralized processing units (vCPUs) instead of fewer instances with more vCPUs

Selected Answer: A

Preemptible VMs are cost-effective instances that can be used for short-lived and non-critical workloads. Since the rendering of individual scenes takes less than 12 hours and can be interrupted and restarted, you can leverage preemptible VMs to perform the rendering tasks. Preemptible VMs are available at a significantly lower cost compared to regular instances but can be preempted by GCP with a 30-second notice. By designing your rendering workflow to handle interruptions gracefully, such as checkpointing and resuming, you can take advantage of the cost savings provided by preemptible VMs.

I had no idea what to say, but chose A because "there is no service level agreement" and because preemptible instances are both cost-effective and would likely lend themselves well to a situation where support is limited.

Answer A: "Preemptible VM instances are available at much lower price—a 60-91% discount—compared to the price of standard VMs. However, Compute Engine might stop (preempt) these instances if it needs to reclaim the compute capacity for allocation to other VMs"

Selected Answer: A

Preemptible VMs are highly affordable, short-lived compute instances suitable for batch jobs and fault-tolerant workloads. Preemptible VMs offer the same machine types and options as regular compute instances and last for up to 24 hours.

Per Google docs, "Preemptible VM instances are available at much lower price—a 60-91% discount—compared to the price of standard VMs. However, Compute Engine might stop (preempt) these instances if it needs to reclaim the compute capacity for allocation to other VMs" https://cloud.google.com/compute/docs/instances/preemptible#what_is_a_preemptible_instance

12h ok, is compatible with the restart time palnned for premptible VMs (24H), and also unpredictable stop of VMs
