A marketer is using new creatives to expand an ad campaign for a tea shop.Which set of steps are relevant in the creative-serving process?

The correct answer is "creative rotation rules, creative weight, and creative scheduling" because these three elements directly control how creatives are served within an ad campaign in Campaign Manager 360. Creative rotation rules determine the method by which different creatives are shown (e.g., even, sequential, optimized). Creative weight assigns a relative frequency to each creative, influencing how often it appears compared to others. Creative scheduling defines specific dates and times for creatives to run. "Creative flight dates" is similar to scheduling but less granular. "Creative type" and "creative length" are attributes of the creative itself, not serving mechanisms.
