AIF-C01 Fundamentals of AI and ML Practice Question
A company is using Amazon Rekognition to detect objects in images. They find that the service sometimes mislabels objects. What is the best way to improve accuracy for their specific use case?
⚠ Common exam trap
Watch out — candidates often assume increasing the confidence threshold is a universal fix for accuracy issues, but the AIF-C01 exam tests the understanding that pre-trained services have limitations and that custom training (via SageMaker) is required for domain-specific improvements.

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
✓
Use Amazon SageMaker to build a custom model
Amazon Rekognition is a pre-trained service that may not perform optimally for specialized or domain-specific use cases. By using Amazon SageMaker to build a custom model, you can train a model on your own labeled dataset, which directly addresses the mislabeling issue by tailoring the model to your specific images and objects.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use a larger image size
Why it's wrong here
Larger images may contain more detail but do not inherently improve detection accuracy without model adaptation.
- ✗
Contact AWS support
Why it's wrong here
Support can help with issues but not improve model accuracy for a specific use case.
- ✗
Increase the confidence threshold
Why it's wrong here
Raising the threshold only reduces low-confidence detections but does not improve model recognition.
- ✓
Use Amazon SageMaker to build a custom model
Why this is correct
A custom model trained on domain-specific data can significantly improve accuracy.
