A data analyst needs to extract data from a REST API that returns paginated results. The API uses a cursor-based pagination mechanism. The analyst wants to ensure that no records are missed during extraction. What should the analyst do?

Use a random offset to sample pages

Follow the cursor links provided by the API until the last page

Request a large page size to get all records in one request

Use page numbers and increment until an empty page is returned

A logistics company needs to ingest GPS location data from delivery trucks. The data is generated every second and sent to a cloud message broker. The company also has a static database of truck routes. Which data acquisition sources are being used?

Files for GPS data and API for routes

API for GPS data and files for routes

Streaming platform for GPS data and database for routes

Database for GPS data and streaming platform for routes

What does data provenance describe?

The origin and history of the data

A data scientist is building a dataset by querying a production PostgreSQL database. The query joins several tables and applies filters. The scientist needs to ensure that the extracted data is reproducible for future model retraining. Which practice best supports this goal?

Create a view in the database and query the view each time the model is retrained.

Export the result to a CSV file and store it in a versioned data lake with a manifest that includes the query, database version, and extraction timestamp.

Run the query and save the output to a local file, then document the table names in a README.

Save the query text and the timestamp of execution, then store the result as a CSV file.
