CompTIA Data+ DA0-002 (V2) Practice Question

The correct answer is Web scraping. This technique involves using an automated script or bot to extract data directly from the HTML of websites. It is commonly used when data is publicly visible on a site but not available through a structured method like an Application Programming Interface (API).

• API integration is incorrect because the scenario explicitly states that an API is not available. An API provides a structured, predefined way for applications to communicate and exchange data, which is different from parsing raw HTML.
• Database querying is incorrect because this method involves retrieving data from a structured database, typically using a language like SQL. The data source in the scenario is external websites, not an internal or accessible database.
• Log file analysis is incorrect as it involves examining machine-generated log files from servers, applications, or networks to monitor activity, troubleshoot issues, or investigate security events. This is fundamentally different from extracting content from a public webpage.
