Correct Answer: A, CTo initiate the ingestion of files into the company's Snowflake account from AWS S3 storage, the process typically involves detecting new files in S3 and triggering Snowpipe for data loading. Configuring a client application to call the Snowpipe REST endpoint when new files arrive in Amazon S3 storage (Option A) provides a direct and flexible method for initiating ingestion. Additionally, creating an AWS Lambda function to call the Snowpipe REST endpoint when new files arrive in Amazon S3 storage (Option C) is another efficient approach leveraging Amazon's serverless computing to handle the event-driven architecture for automatically triggering Snowpipe ingestion.
