For this question, refer to the Mountkirk Games case study.
MountKirk Games uses Kubernetes and Google Kubernetes Engine and wants to Use GPU processing to render graphics server-side. But GPUs are expensive so they are planning to use preemptible VMs and GPU nodes in a nodepool.
What do they have to perform for the above solution?
A. Create a node pool with preemptible VMs
B. Create a node pool with non-preemptible VMs
C. Remove the taint nvidia.com/gpu=present:NoSchedule
D. Let System Pods run with non-preemptibleVMs
Correct Answer: C
System Pods have to run with non-preemptible VMs, otherwise, it would be dangerous when the node gets removed.
So you have to avoid having only node pools with GPU preemptible VMs. In this case, the taint nvidia.com/gpu=present:NoSchedule should be removed.
And it is OK to have at least a node pool with non-preemptible VMs, in addition to GPU preemptible VMs.
- Option A is wrong because it is OK to have a node pool with preemptible VMs when you have at least a node pool with non-preemptible VMs.
- Option B is wrong because it is OK to use GPU preemptible VMs.
- Option D is wrong because it would be dangerous when System Pods will get removed.
