DA0-002 Data Acquisition and Preparation Practice Question
A data analyst needs to collect customer sentiment data from social media platforms. Which data acquisition method is most appropriate?
⚠ Common exam trap
CompTIA often tests the distinction between primary data collection (surveys, focus groups) and secondary data acquisition (web scraping, APIs), where candidates mistakenly choose a primary method for a task that requires large-scale, unsolicited external data.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use web scraping
Web scraping is the most appropriate method because it allows the data analyst to programmatically extract unstructured customer sentiment data (e.g., posts, comments, reviews) directly from social media platforms using HTTP requests and HTML parsing. Unlike surveys or focus groups, scraping can collect large volumes of real-time, publicly available data without relying on self-reported or curated responses.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Conduct a survey
Why it's wrong here
Surveys are useful for direct feedback but not for passive social media data.
- ✗
Organize focus groups
Why it's wrong here
Focus groups are qualitative and small-scale, not suitable for large-scale social media collection.
- ✓
Use web scraping
Why this is correct
Web scraping automates extraction of data from social media platforms.
- ✗
Query the internal CRM
Why it's wrong here
CRM contains internal customer data, not external social media sentiment.
