Why should changing the reporting source after an activity goes live be avoided when configuring "Reporting Settings" in Adobe Target?

Explanation

Changing the reporting source after an activity goes live should be avoided because it causes inconsistent data - reports collected before the change used one methodology, and reports after use another, making it impossible to draw valid conclusions from the combined data. Option C is correct because the entire purpose of this restriction is to keep reports consistent throughout the activity's lifecycle.

Why the distractors are wrong:

• A (duplicate reports): Changing the source doesn't duplicate anything; it splits data across incompatible systems.
• B (change all reporting settings): Only the reporting source is affected, not every setting in the configuration.
• D (delete historical data): Historical data isn't deleted - it becomes incomparable and unreliable, which is a different (and subtler) problem.

Memory tip: Think of it like switching measuring units mid-experiment - you don't lose your old measurements in inches, but mixing them with new centimeter readings makes the whole dataset meaningless. Consistency is the keyword Adobe Target is protecting.
