Which two types of creatives either float above a webpage or fill an entire mobile screen? (select two)

Interstitial creatives are full-screen ads that cover the interface of their host application or webpage, typically appearing at natural transition points, like between activities or levels in a game. Floating creatives, also known as overlay ads, appear superimposed over the content of a webpage, often with a close button, and can move with the user's scroll. Both types are designed to command user attention by obscuring or covering the primary content. Expandable creatives are initially small but expand upon user interaction, not automatically floating or filling the screen. Banner creatives are static or animated images typically placed in designated ad slots, not floating or full-screen.
