- A
Limited API rate limits
Why wrong: Rate limits apply to APIs, not web scraping.
- B
Legal and ethical restrictions
Many websites prohibit scraping in their terms of service, and legal issues may arise.
- C
Website structure changes
Websites frequently update their layout, breaking scrapers that rely on specific HTML elements.
- D
High latency of data transfer
Why wrong: Latency is not a typical challenge specific to web scraping.
- E
Inconsistent data formatting
Why wrong: While possible, formatting issues are often handled by data cleaning; not a primary challenge.

DA0-001 Data Concepts and Environments Practice Question
This DA0-001 practice question tests your understanding of data concepts and environments. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 data analyst is extracting data from a web page using web scraping techniques. The data will be used for market research. Which TWO of the following are common challenges associated with web scraping?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Legal and ethical restrictions
Option B is correct because web scraping often involves accessing data that may be protected by copyright, terms of service, or privacy regulations such as GDPR or the Computer Fraud and Abuse Act (CFAA). Even if data is publicly accessible, repurposing it for market research without permission can lead to legal liability or ethical violations, making this a fundamental challenge.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between API-related challenges (rate limits, authentication) and web-scraping-specific challenges (structure changes, legal/ethical issues), so candidates mistakenly select 'Limited API rate limits' because they confuse web scraping with API consumption.
Detailed technical explanation
How to think about this question
Web scraping relies on parsing the DOM (Document Object Model) of a web page, which is subject to change whenever the site's front-end code is updated—even a minor CSS class rename can break XPath or CSS selectors. Additionally, many sites employ anti-bot measures such as JavaScript challenges, CAPTCHAs, or dynamic content loading via AJAX, which require headless browsers (e.g., Puppeteer, Selenium) and increase complexity. The legal landscape varies by jurisdiction; for instance, the 2019 hiQ Labs v. LinkedIn ruling highlighted that scraping publicly accessible data may not violate the CFAA, but terms of service violations remain a contractual risk.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
