CIW DATA ANALYST
1D0-622 PRACTICE EXAM
48 QUESTIONS
Question 1: A retailer is preparing a demand analysis. Store managers have useful undocumented knowledge about local events that a�ect sales. What should the analyst do �rst?
Choices:
1) Replace transaction data with manager estimates 2) Capture the managers' institutional knowledge and validate it against available data 3) Use only publicly available market data 4) Ignore the managers because undocumented information cannot be analyzed Correct Answer: Capture the managers' institutional knowledge and validate it against available data Explanation: Institutional or tribal knowledge can explain patterns that formal systems do not capture. The analyst should document it and validate it against objective source data before using it in decisions.Page 1
Question 2: Several departments maintain separate customer spreadsheets with
con�icting addresses and account statuses. What is the primary analytical bene�t of centralizing the data?
Choices:
1) It guarantees every value is correct without validation 2) It eliminates the need for access controls 3) It converts all unstructured data into structured data automatically 4) It creates a more consistent source of truth and reduces reconciliation work Correct Answer: It creates a more consistent source of truth and reduces reconciliation work Explanation: Centralization reduces con�icting versions of the same business entity and makes consistent analysis easier. Data still requires governance, validation, and appropriate access controls.
Question 3: Which example is the clearest case of unstructured data?
Choices:
1) Recorded customer-support calls and free-form social media comments 2) A table of invoice numbers and amounts 3) A CSV �le containing product quantities 4) A database table containing customer IDs and ZIP codes Correct Answer: Recorded customer-support calls and free-form social media comments Explanation: Audio recordings and free-form text do not naturally �t a �xed row-and-column schema, so they are unstructured. The other examples have de�ned �elds and are structured.Page 2
Question 4: An analyst wants to understand why online revenue fell last month.
Which source combination is most likely to provide a useful cross-functional view?
Choices:
1) Web tra�c, sales transactions, marketing campaign data, and customer-support records 2) Only the o�ce supply purchasing log 3) Only the employee directory 4) Only the current inventory count Correct Answer: Web tra�c, sales transactions, marketing campaign data, and customer- support records Explanation: A revenue decline can involve tra�c, conversion, promotions, sales activity, and customer issues. Combining relevant sources produces a stronger business view than relying on one unrelated or narrow source.
Question 5: A company runs promotions through email, search, social media, and
o�ine events. Which practice best supports SEO and channel analysis?
Choices:
1) Track source and campaign information so performance can be compared across channels 2) Measure every channel with the same unnamed tra�c category 3) Exclude o�ine campaigns because they cannot in�uence online behavior 4) Count only visits from search engines Correct Answer: Track source and campaign information so performance can be compared across channels Explanation: Consistent source and campaign tracking lets analysts compare how channels contribute to tra�c and outcomes. SEO analysis is more useful when search performance is interpreted alongside other acquisition channels.Page 3
