The correct answer is A. Use Amazon SageMaker Data Wrangler preconfigured transformations to explore feature. The data science team needs to interactively explore and visualize feature transformations on S3 tabular data, then automate the workflow with high operational efficiency.
Question
A data science team is working with a tabular dataset that the team stores in Amazon S3. The team wants to experiment with different feature transformations such as categorical feature encoding. Then the team wants to visualize the resulting distribution of the dataset. After the team finds an appropriate set of feature transformations, the team wants to automate the workflow for feature transformations. Which solution will meet these requirements with the MOST operational efficiency?
Options
- AUse Amazon SageMaker Data Wrangler preconfigured transformations to explore feature
- BUse an Amazon SageMaker notebook instance to experiment with different feature
- CUse AWS Glue Studio with custom code to experiment with different feature transformations.
- DUse Amazon SageMaker Data Wrangler preconfigured transformations to experiment with

Why each option
The data science team needs to interactively explore and visualize feature transformations on S3 tabular data, then automate the workflow with high operational efficiency.
Amazon SageMaker Data Wrangler provides a visual interface with preconfigured transformations and data quality insights, enabling interactive exploration and visualization of feature transformations with high operational efficiency. After finding appropriate transformations, Data Wrangler can generate the code for a SageMaker Processing job or PySpark script, facilitating easy automation of the entire workflow.
Using a SageMaker notebook instance requires manual coding for each transformation, visualization, and automation step, making it less operationally efficient for iterative exploration compared to Data Wrangler's visual tools.
AWS Glue Studio with custom code is powerful for ETL but involves more manual coding for exploration and visualization compared to Data Wrangler, making it less efficient for a data scientist's interactive experimentation phase.
This choice is a partial description of Data Wrangler's capabilities and does not fully encompass the end-to-end workflow, including visualization and automation, as comprehensively as option A.
