Question 100
A sports analyst must identify a sequence of events in a short replay, not just the final frame. Which input capability matters?
- Single-frame image recognition without temporal tracking
- Text-only input pipeline
- Video understanding model
- Audio understanding model
Explanation
Correct Answer
C:The temporal order of frames is the essential evidence. Video understanding accounts for visual changes or events across time in moving clips.
Incorrect Answers
A:A still-image recognizer can inspect one frame but cannot by itself establish the temporal order of events throughout the replay.
B:A text-only pipeline interprets character or token sequences but does not directly analyze image pixels. This does not directly meet the case requirement to analyze events across a video sequence.
D:Audio understanding interprets speech or other audio characteristics. This does not directly meet the case requirement to analyze events across a video sequence.
Question 101
A company exports orders as rows containing order ID, total and purchase date. Which data format class best represents the export?
- Time-series measurements

Explanation
Correct Answer
C:The records follow fixed columns that support SQL-style queries. Structured data uses an explicit schema with consistent fields, rows or columns suited to querying.
Incorrect Answers
A:Time-series data is ordered by observation time and supports temporal trend analysis. This does not directly meet the case requirement to store and query rows with predictable fields.
B:Images contain visual pixel information rather than native structured business attributes. This does not directly meet the case requirement to store and query rows with predictable fields.
D:Audio data contains sound signals requiring audio-aware processing or transcription. This does not directly meet the case requirement to store and query rows with predictable fields.
Question 102

Explanation
Correct Answer
A:The format carries machine-readable structure with variable nested content. Semi-structured data has explicit keys or tags but can vary in nesting or fields across records.
Incorrect Answers
B:Audio data contains sound signals requiring audio-aware processing or transcription. This does not directly meet the case requirement to represent records with flexible keys and nesting.
C:Structured data uses an explicit schema with consistent fields, rows or columns suited to querying. This does not directly meet the case requirement to represent records with flexible keys and nesting.
D:Time-series data is ordered by observation time and supports temporal trend analysis. This does not directly meet the case requirement to represent records with flexible keys and nesting.
Question 104
A factory captures a temperature reading every minute and must examine daily trends. What data arrangement captures the key property?
- Image files
- Unstructured document content
- Time-series measurements
- Semi-structured JSON
Explanation
Correct Answer
C:The time order is central to interpreting the measurements. Time-series data is ordered by observation time and supports temporal trend analysis.
Incorrect Answers
A:Images contain visual pixel information rather than native structured business attributes. This does not directly meet the case requirement to analyze measurements indexed by time.
B:Unstructured content such as free-text documents and photographs lacks one fixed row-column schema. This does not directly meet the case requirement to analyze measurements indexed by time.
D:Semi-structured data has explicit keys or tags but can vary in nesting or fields across records. This does not directly meet the case requirement to analyze measurements indexed by time.
Question 105
A call center wants to understand tone and speech in recorded calls. What type of source data is central?
- Semi-structured JSON
- Structured tabular records
- Time-series measurements
- Audio recordings
Explanation
Correct Answer
D:Sound information must be processed before it becomes text features. Audio data contains sound signals requiring audio-aware processing or transcription.
Incorrect Answers
A:Semi-structured data has explicit keys or tags but can vary in nesting or fields across records. This does not directly meet the case requirement to interpret speech and other sound signals.
B:Structured data uses an explicit schema with consistent fields, rows or columns suited to querying. This does not directly meet the case requirement to interpret speech and other sound signals.
C:Time-series data is ordered by observation time and supports temporal trend analysis. This does not directly meet the case requirement to interpret speech and other sound signals.
Question 106
An ecommerce vendor wants to analyze a photo catalog for damaged packaging. Which source type is involved?
- Semi-structured JSON
- Structured tabular records
- Time-series measurements
- Image files
Explanation
Correct Answer
D:Visual features exist in picture data rather than order fields. Images contain visual pixel information rather than native structured business attributes.
Incorrect Answers
A:Semi-structured data has explicit keys or tags but can vary in nesting or fields across records. This does not directly meet the case requirement to inspect photographic pixels for damage.
B:Structured data uses an explicit schema with consistent fields, rows or columns suited to querying. This does not directly meet the case requirement to inspect photographic pixels for damage.
C:Time-series data is ordered by observation time and supports temporal trend analysis. This does not directly meet the case requirement to inspect photographic pixels for damage.
Question 107
A finance table has salary, department and currency fields with one row per employee. Which category applies?
- Audio recordings
- Unstructured document content
- Image files
