¿Cuál de los siguientes tipos de promoción es un arreglo prenegociado entre un editor y un anunciante?

Programmatic Guaranteed is a pre-negotiated deal between a publisher and an advertiser for a fixed price and guaranteed impressions. This ensures the advertiser gets a specific inventory at a set rate, and the publisher secures revenue. Private Auction (PMP) involves an invitation-only auction where multiple advertisers bid for inventory, but it's not guaranteed. Preferred Deal is a non-guaranteed deal where the advertiser gets first look at inventory at a fixed price, but doesn't guarantee impressions.
