The 'config.pbtxt' file (or its binary Protobuf equivalent) is the primary configuration file used by Triton Inference Server to define the model's properties, input/output schemas, backend, and execution parameters.

DCGM provides detailed GPU-specific metrics. Prometheus is a popular time-series database and monitoring system that excels at collecting data from various sources. Grafana provides powerful visualization capabilities. This combination offers a scalable and comprehensive monitoring solution. Other options might provide some of the necessary functionality, but lack the integrated GPU-specific monitoring or scalability features of the DCGM-Prometheus-Grafana stack. Nsight Systems is primarily for profiling, not continuous monitoring.

Device targeting with labels is the most efficient and scalable way to manage deployments to diverse hardware. Separate organizations (A) are overly complex. Manual selection (C) is error-prone. Relying on automatic adaptation (D) might not be reliable. Custom scripts (E) add unnecessary complexity when Fleet Command provides built-in features.

Using the NVIDIA Device Plugin allows for dynamic injection of driver libraries. Baking the driver into the container also works, but it results in a larger image and less flexibility. Option A is not a valid resource limit. Overriding the host OS driver is not practical for multi-tenant environments. Relying on host inheritance is risky as driver versions can vary.

B, D and E are the correct. GitLab CI/CD with kaniko and Helm provides a robust and scalable solution for building and deploying container images. NGC CLI allows fetching and deploying pre-built containers, simplifying the process. AWS CodePipeline, CodeBuild, and EKS offer a complete CI/CD solution within the AWS ecosystem. Option A is a valid but less modern approach. Option C lacks a structured deployment process.
