A healthcare research group wants to combine electronic health records (structured tables), physician notes (free text), and medical imaging scans (DICOM files) to build a patient risk model. Their current relational data warehouse rejects the text and image files. What is the primary Big Data challenge they are encountering, and what technology would best support their goal?

Volume challenge; purchase more storage for the relational warehouse to accommodate the new data types.

Velocity challenge; implement a faster ETL pipeline to load the new data types into the warehouse.

Veracity challenge; clean the text and image data to fit the warehouse schema.

Variety challenge; use a data lake that can store structured, semi-structured, and unstructured data in their native formats.

Which of the following is a challenge specific to real-time processing of streaming data?

Data is always clean and structured.

Handling out-of-order data and ensuring event-time accuracy.

Data is always stored in a data warehouse.

Data is always processed in large batches.
