Question 32 of 280

Single answer
You developed an ML model with AI Platform, and you want to move it to production. You serve a few thousand queries per second and are experiencing latency issues. Incoming requests are served by a load balancer that distributes them across multiple Kubeflow CPU-only pods running on Google Kubernetes Engine (GKE). Your goal is to improve the serving latency without changing the underlying infrastructure. What should you do?
ASignificantly increase the max_batch_size TensorFlow Serving parameter.
BSwitch to the tensorflow-model-server-universal version of TensorFlow Serving.
CSignificantly increase the max_enqueued_batches TensorFlow Serving parameter.
DRecompile TensorFlow Serving using the source to support CPU-specific optimizations. Instruct GKE to choose an appropriate baseline minimum CPU platform for serving nodes.
Correct Answer: A

Significantly increase the max_batch_size TensorFlow Serving parameter.
