A delivery group is running four ads in sequential rotation with frequency cap set at three impressions per user per day.Which creative instance will load when served for the fourth time to the same user in the same day?

When a frequency cap is reached, the ad server will stop displaying the campaign's ads to that specific user for the remainder of the frequency cap period. Instead of showing another ad from the sequence, which would violate the frequency cap, the server will display a default image. This ensures the user experience is not negatively impacted by excessive ad exposure and that campaign rules are adhered to. The first ad in the sequence would only load if the frequency cap had not been reached or if it was the first impression. The fourth ad in the sequence would not load because the frequency cap of three impressions per user per day has already been met.
