Exam Certified Data Architect topic 1 question 90 discussion

C is better answer. A is still too manual, PK chunking would we better.

A is correct: Chunking the Data into Smaller Sets ... 2. Create a formula field that converts the auto-number field text value into a numeric value—you cannot use an index with comparison operators such as “<=” (less than or equal to) or “>” (greater than) for the text-based auto-number field. In this example, we’ll name this field “ExportID.” https://developer.salesforce.com/blogs/engineering/2013/06/extracting-large-data-volume-ldv-in-force-com

So the correct answers are A ore C? I vote C

The most accurate answer would be Option C: Use extract, transform, load (ETL) tool for extraction of records. ETL tools are designed to handle large volumes of data and can efficiently extract, transform, and load data without running into time-out issues. They can also chunk data into manageable sizes for extraction, which can help avoid time-out issues.

B is correct as it also depends on the ETL tool on which api is used by it.
