AIF-C01 Fundamentals of AI and ML Practice Question
A company uses Amazon SageMaker to train a model. The training job fails with 'InsufficientInstanceCapacity' error. What is the most likely cause?
⚠ Common exam trap
The AIF-C01 exam often tests the distinction between capacity errors and throttling errors, so the trap here is confusing 'InsufficientInstanceCapacity' with a rate-limiting or quota error, leading candidates to incorrectly select Option A.
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
✓
The requested instance type is not available in the specified region.
The 'InsufficientInstanceCapacity' error in Amazon SageMaker indicates that AWS does not currently have enough available capacity for the requested instance type in the specified region or Availability Zone. This is a common transient error when demand for a particular instance type exceeds supply, and it is not related to request rate, dataset size, or image compatibility.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The request rate is too high.
Why it's wrong here
Rate limiting does not produce this error.
- ✗
The dataset size exceeds the instance storage limit.
Why it's wrong here
This would cause a different error, like disk full.
- ✓
The requested instance type is not available in the specified region.
Why this is correct
This error occurs when AWS cannot provision the instance due to capacity constraints.
- ✗
The training image is not compatible with the instance type.
Why it's wrong here
Incompatibility would cause a different error, such as 'Cannot pull image'.
