Question

Data brokers use data mining techniques to combine what? (Choose all that apply)


stolen data


data purchased from other businesses


general data collected by web crawlers


publicly accessible data

Answer 1

Choose:
- data purchased from other businesses
- general data collected by web crawlers
- publicly accessible data

Explanation: Data brokers aggregate and merge information from public records, web crawling/scraping, and datasets bought from other companies (loyalty programs, marketing lists, etc.). Stolen data is not a legitimate/standard source (although breaches can sometimes leak into secondary markets), so it’s not a correct selection here.
