MLS-C01 Modeling Practice Question
A data scientist is using Amazon SageMaker to train a model. The training dataset is stored in S3 as CSV files. The scientist wants to use the SageMaker built-in Linear Learner algorithm. Which input mode should be used for optimal performance?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Pipe mode
Pipe mode streams data directly from S3 to the algorithm without writing to disk, reducing I/O overhead. File mode downloads the entire dataset to disk, which is slower. Fast file mode is not a SageMaker feature. Augmented manifest is for additional metadata, not performance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Augmented manifest file mode
Why it's wrong here
Augmented manifest is for attribute metadata, not for performance.
- ✗
File mode
Why it's wrong here
File mode downloads data to disk, causing higher I/O latency.
- ✓
Pipe mode
Why this is correct
Pipe mode streams data, reducing I/O overhead and improving performance.
- ✗
Fast file mode
Why it's wrong here
Fast file mode is not a SageMaker input mode.
