A company's analytics manager wants all reports to be delivered once every seven days. Which of the following is the best delivery method?
Answer(s): A
This question pertains to the Visualization and Reporting domain, focusing on report delivery methods. The requirement for delivery every seven days indicates a scheduled, repeating process.Recurring (Option A): Recurring delivery schedules reports to be generated and delivered at regular intervals (e.g., weekly), which matches the requirement of every seven days.Ad hoc (Option B): Ad hoc reports are one-time, on-demand reports, not suitable for scheduled delivery.Custom (Option C): Custom isn't a standard delivery method; it might refer to tailored reports but doesn't imply scheduling.Snapshot (Option D): A snapshot captures data at a specific point, not suitable for recurring delivery.The DA0-002 Visualization and Reporting domain includes "the appropriate visualization in the form of a report" with delivery methods, and recurring delivery is ideal for weekly reports.
