Quick Answer
The correct answer is to limit request rate, alongside respecting robots.txt and identifying yourself with a user-agent. These three practices form the ethical backbone of web scraping because they prevent server overload, honor site owners’ access rules, and ensure transparency about who is collecting data. On the CompTIA Data+ DA0-001 exam, this question tests your understanding of responsible data acquisition under the “Data Governance” domain, where candidates often confuse technical workarounds—like using multiple IP addresses—with actual best practices. A common trap is assuming that scraping everything available is acceptable if the data is public, but the exam emphasizes that ignoring a site’s robots.txt or failing to throttle requests violates both ethics and potential legal terms. To remember the three pillars, think of the acronym RUL: Rate-limit, User-agent, and Legality (robots.txt).
This DA0-001 practice question tests your understanding of mining and acquiring data. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which THREE are best practices for acquiring data via web scraping? (Select exactly 3)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Use multiple IP addresses
Why wrong: Not a best practice; may violate terms.
Respect robots.txt
Legal and ethical best practice.
Identify yourself with a user-agent
Transparency best practice.
Scrape all data without regard to terms
Why wrong: Unethical and possibly illegal.
Limit request rate
Avoid overloading servers.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Respect robots.txt
Options A, B, and E are correct because best practices include respecting robots.txt (legal and ethical), limiting request rate (avoid overloading servers), and identifying yourself with a user-agent (transparency). Option C is wrong because using multiple IP addresses may be necessary but is not a best practice per se; it can be used to avoid blocking but may violate terms. Option D is wrong because scraping all data without regard to terms is unethical and possibly illegal.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
