Quick Answer
The correct choice is external public web scraping because competitor pricing is publicly available on websites, and web scraping enables automated extraction of this data for competitive intelligence. This technique directly gathers external data from public sources, bypassing the need for internal records or customer surveys, which would be unreliable for pricing comparisons. On the CompTIA Data+ DA0-001 exam, this question tests your ability to match data sources to business needs—specifically, distinguishing between internal, external, and third-party sources. A common trap is selecting “internal sales data” or “customer feedback,” but those lack the real-time, external view of competitor pricing. Remember the memory tip: “If it’s on the web and public, scrape it for external insight.” This reinforces that web scraping is the most appropriate when the goal is automated, scalable collection of publicly available external data.
This DA0-001 practice question tests your understanding of mining and acquiring data. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A marketing team wants to collect data on competitor pricing for similar products. Which data source is most appropriate?
Customer surveys
Why wrong: Surveys provide opinions but not actual competitor prices.
Internal ERP system
Why wrong: ERP contains internal operational data, not external market data.
External public web scraping
Web scraping can collect competitor pricing from public websites.
Internal sales data
Why wrong: Internal sales data shows own pricing, not competitors'.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
External public web scraping
External public web scraping is the most appropriate data source because competitor pricing is publicly available on websites, and web scraping allows automated extraction of this structured or unstructured data. This approach directly addresses the need for external competitive intelligence without relying on internal or customer-reported data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Customer surveys
Why it's wrong here
Surveys provide opinions but not actual competitor prices.
Internal ERP system
Why it's wrong here
ERP contains internal operational data, not external market data.
External public web scraping
Why this is correct
Web scraping can collect competitor pricing from public websites.
Related concept
Read the scenario before looking for a memorised answer.
Internal sales data
Why it's wrong here
Internal sales data shows own pricing, not competitors'.
Common exam traps
The trap here is that candidates may confuse internal data sources (ERP, sales) with external data needs, or mistakenly think customer surveys can provide accurate, unbiased competitor pricing data.
Trap categories for this question
Command / output trap
Internal sales data shows own pricing, not competitors'.
Detailed technical explanation
Web scraping typically involves sending HTTP GET requests to target URLs, parsing the returned HTML using libraries like BeautifulSoup or Scrapy, and extracting specific elements via CSS selectors or XPath. Real-world considerations include respecting robots.txt, handling rate limiting, and dealing with dynamic content rendered by JavaScript, which may require headless browsers like Selenium or Puppeteer.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the DA0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
