NEW QUESTION # 22
You need to deploy a pod that requires access to a specific GPU device. How can you ensure that
the pod is scheduled on a node with the required GPU?

A. Use the 'affinity' field to prefer nodes with the 'GPU* label.
B. Use the 'tolerations' field to tolerate the 'GPU' taint.
C. Use the 'podAffinity' field to group pods with GPU requirements together.
D. Use the 'resources' field to specify the GPU requirements in the container's definition.
E. Use the 'nodeSelector' field to target nodes with the 'gpu' label.

Answer: D

Explanation:
You can use both the •nodeselector• and •resources' fields to achieve this: 'nodeselector•: Targets nodes with a label indicating the presence of GPUs (e.g., •gpu: true). •resources': Specify the GPU resource requirements within the container's definition. This provides a more precise way to request specific GPUs and their capabilities. While •tolerations' and 'affinity' can be used for other scheduling needs, they are not directly designed for GPU resource allocation.

NEW QUESTION # 23
