Northern Trail Outfitters wants to provide near real-time data in a 30-day welcome journey.

Synchronized Data Sources — Salesforce objects synced into Marketing Cloud through Marketing Cloud Connect as Synchronized Data Extensions — refresh on a near-real-time cadence, making them the correct data foundation whenever a long-running journey (here, spanning 30 days) needs decision splits to evaluate current, up-to-date CRM data rather than a stale snapshot captured only at the moment of journey entry. Because Contact Data-based Decision Splits can reference these synchronized sources through Attribute Groups, each split evaluation during the 30-day journey reflects the latest state of the underlying Salesforce data, satisfying the ' near real-time ' requirement across the journey ' s full duration. Option A describes routing CRM data through a Report and a Data Copy or Import activity into a Salesforce Data Extension — a batch, scheduled process that introduces latency inconsistent with near-real-time needs. Option B, Journey Data queried from the main data extension, reflects only the state of the data at the point of entry and does not refresh as the journey progresses over 30 days, making it unsuitable for evaluating current conditions mid-journey. Option D, Profile Attributes mapping, is a legacy mechanism tied to profile/demographic data structures and does not provide the same near-real-time synchronization guarantees as Synchronized Data Sources.
