An Auto Loader JSON source introduces a previously unseen optional property, and operations accept a controlled stream restart when schema changes.
Which acceptance result most directly demonstrates that the intended solution works?
Auto Loader can append new columns to its tracked schema before stopping the stream for restart under addNewColumns.
A new unknown input attribute appears in rescued data rather than in the registered table schema. That finding does not establish that after restart the new property appears as a target column while earlier rows still load normally.
An identifier such as 00073 stays exactly five characters in the bronze table. That finding does not establish that after restart the new property appears as a target column while earlier rows still load normally.
The column names match the header and the header text is absent from the target data rows. That finding does not establish that after restart the new property appears as a target column while earlier rows still load normally.
A compliance feed must never add new columns to the target schema automatically, but engineers need the unexpected values for investigation.
Which implementation decision best addresses this requirement?
The rescue mode preserves schema stability while recording new or mismatched fields separately instead of evolving columns. The selected implementation is the one directly aligned with the constraints in the scenario.
Fail-on-new-columns prevents unreviewed schema expansion instead of silently accepting the upstream change.
The binary file source exposes paths and payload content rather than interpreting every object as a tabular JSON record.
The outer cloudFiles format invokes Auto Loader while the cloudFiles.format option identifies the source file parser.

Which acceptance result most directly demonstrates that the intended solution works?
The rescue mode preserves schema stability while recording new or mismatched fields separately instead of evolving columns.
A file containing an unapproved column stops ingestion until the schema contract is deliberately revised. That finding does not establish that a new unknown input attribute appears in rescued data rather than in the registered table schema.
An image arrives with its file metadata and binary payload intact in the downstream extraction process. That finding does not establish that a new unknown input attribute appears in rescued data rather than in the registered table schema.
A representative nested JSON file is decoded correctly rather than treated as comma-delimited text. That finding does not establish that a new unknown input attribute appears in rescued data rather than in the registered table schema.
An upstream partner accidentally adds a new attribute and the ingestion policy requires manual schema approval before processing can resume.
Which implementation decision best addresses this requirement?
Fail-on-new-columns prevents unreviewed schema expansion instead of silently accepting the upstream change. The selected implementation is the one directly aligned with the constraints in the scenario.
Identifier preservation requires controlling the inferred data type rather than relying on parsing heuristics.
Keeping nested payloads at the ingestion boundary preserves source fidelity for later transformations.
Event-driven discovery can reduce repeated listing work on very large incremental file streams.

An identifier such as 00073 stays exactly five characters in the bronze table. That finding does not establish that a file containing an unapproved column stops ingestion until the schema contract is deliberately revised.
A sample record retains its array and nested object fields in bronze and can be exploded downstream. That finding does not establish that a file containing an unapproved column stops ingestion until the schema contract is deliberately revised.
New objects are discovered through the configured event path without repeatedly enumerating the entire old directory. That finding does not establish that a file containing an unapproved column stops ingestion until the schema contract is deliberately revised.
A CSV file has a numeric-looking account identifier that must retain leading zeros and must not be inferred as an integer.
Which implementation decision best addresses this requirement?
Identifier preservation requires controlling the inferred data type rather than relying on parsing heuristics. The selected implementation is the one directly aligned with the constraints in the scenario.
The binary file source exposes paths and payload content rather than interpreting every object as a tabular JSON record.
Without the correct CSV reader option, the heading line can be parsed as a normal data record.
Directory listing is a supported discovery mode and can be simpler for bounded workloads.

The column names match the header and the header text is absent from the target data rows. That finding does not establish that an identifier such as 00073 stays exactly five characters in the bronze table.
A newly dropped file is discovered in the next processing cycle without requiring a configured notification queue. That finding does not establish that an identifier such as 00073 stays exactly five characters in the bronze table.
A data lake has compressed JSON text files mixed with image files that must be preserved as raw payloads for a classification pipeline.
Which implementation decision best addresses this requirement?
The binary file source exposes paths and payload content rather than interpreting every object as a tabular JSON record. The selected implementation is the one directly aligned with the constraints in the scenario.
Keeping nested payloads at the ingestion boundary preserves source fidelity for later transformations.
The outer cloudFiles format invokes Auto Loader while the cloudFiles.format option identifies the source file parser.
Available-now processing applies incremental streaming logic to currently available data while allowing the run to terminate.

The job processes the available backlog and reaches a completed state without a permanently active stream. That finding does not establish that an image arrives with its file metadata and binary payload intact in the downstream extraction process.
A mobile-app event payload nests arrays of product attributes inside a JSON object, and ingesting it must not discard nested structure.
Which implementation decision best addresses this requirement?
Keeping nested payloads at the ingestion boundary preserves source fidelity for later transformations. The selected implementation is the one directly aligned with the constraints in the scenario.
Without the correct CSV reader option, the heading line can be parsed as a normal data record.
Event-driven discovery can reduce repeated listing work on very large incremental file streams.
Changing the checkpoint path creates a new stream identity and can cause already seen files to be processed again.
