No, the Sony A7C II is not compatible with the Sony Tough CEA-G480T 480GB CFexpress Type A.
Sony A7C II supports only SD memory cards (UHS-II compatible) per Sony's own Help Guide -- no CFexpress card slot exists on this body. Sony Tough CEA-G480T is CFexpress Type A only and cannot physically be used with this camera, regardless of card speed. Note: both being Sony products doesn't mean they're compatible -- the card format itself isn't supported by this body.
