When you complete the questionnaire, you can start evaluating the answers and explanations. After evaluating your score, read the explanations carefully, and you can access the reference documentation of issues that you might have missed where you marked incorrect answers.

Core data concepts

1. Select the correct statement:
   1. ( ) Extract, transform, and load (ETL) can limit the amount of sensitive data that is transferred to target systems
   2. ( ) Extract, load, and transform (ELT) reduces the amount of time needed to copy substantial amounts of data to the target systems
   3. ( ) Extract, load, and transform (ELT) transforms data utilizing a computational resource that is not dependent on the source or target systems
   4. ( ) Extract, transform, and load (ETL) transforms data utilizing a computational resource...
