Question 27. What is the purpose of the method case.getTagSystem() in a script? A) To retrieve a list of all tags applied to items B) To access the hierarchical tag structure for creating or modifying tags C) To export tags to a CSV file D) To delete unused tags Answer: B Explanation: getTagSystem() returns the TagSystem object, which manages the tag hierarchy and definitions.
Question 28. When parsing a CSV file, which Groovy feature automatically converts each line into a list of values? A) CSVReader class B) split(',') method on the line string C) eachLine { line - > line.split(',') } D) Groovy’s built‑in CSV parser (new CsvParser()) Answer: C Explanation: Using eachLine with split(',') is a concise Groovy idiom for turning a line into a list of fields.
