The correct options are Scripts are written for automated repeatable training workflows that prioritize consistency and efficiency, Script files execute code sequentially when invoked which provides a deterministic and controlled execution flow compared to interactive notebooks, and Scripts are generally lean and focus on production code rather than extensive visualizations or experimental notes.

Scripts are written to be run in automated pipelines and production environments and they are designed to accept arguments, handle dependencies, and integrate with CI and scheduling systems. This emphasis on repeatability and efficiency makes scripts suitable for production training jobs and for deployment to services like Vertex AI after packaging and testing.

Script files execute top to bottom when run which provides a deterministic and controlled execution flow. This contrasts with interactive notebooks where cell order and hidden state can lead to nonreproducible results. The sequential execution model makes it easier to test, debug, and validate training runs and to reproduce results reliably.

Scripts are typically lean and focused on production concerns such as data ingestion, model training loops, logging, and saving artifacts. They usually omit extensive exploratory visualizations and narrative notes that are common in notebooks. This focus reduces runtime overhead and simplifies maintenance and reuse in production pipelines.

Scripts are deployed to Vertex AI with no modifications is incorrect because most scripts require packaging, dependency specification, and an appropriate entry point or containerization before they can run on Vertex AI. Deployment to a managed training service normally involves some adaptation to meet runtime and environment requirements.

Scripts are primarily intended for ad hoc exploratory data analysis is incorrect because exploratory analysis is the main purpose of notebooks. Scripts are intended for repeatable, automated, and maintainable workflows rather than for interactive, ad hoc investigation.
