Explain pull vs push ingestion patterns.

• A. Ingestion is performed only after a manual trigger with no automation.
• B. Pull means ingestion on-demand from a source; push means sources push data into Foundry automatically.
• C. Pull means sources push data into Foundry automatically.
• D. Push means ingestion on-demand from a source.

Answer: (B)

Ingestion patterns describe how data arrives into Foundry. Pull ingestion means you actively retrieve data from the source when you want it—on demand, on a schedule, or in response to a trigger you initiate. Push ingestion means the source sends data to Foundry automatically as soon as it’s produced or becomes available, without you pulling it.

This matches the statement: pulling is on-demand from a source, while pushing is the source pushing data into Foundry automatically. The other descriptions mix up who initiates data transfer or imply only manual triggers, which don’t capture the standard behavior of pull versus push.
