MLA-C01 Practice Question: Refer to the exhibit
Exhibit
[2024-01-15 10:30:45] Training job 'my-training-job' started.
[2024-01-15 10:31:10] Using algorithm 'built-in' with hyperparameters: {'epochs': 10, 'batch-size': 32, 'learning-rate': 0.001}
[2024-01-15 10:31:15] File system creation failed: No usable scratch space. Error: Input/output error.
[2024-01-15 10:31:15] Retrying with local SSD...
[2024-01-15 10:31:20] Training completed with status 'Failed'.Refer to the exhibit. The training job failed. What is the MOST likely cause?
⚠ Common exam trap
Candidates often confuse disk space errors with memory errors (Option C) or incorrectly attribute the failure to hyperparameters (Option A or E), when the specific 'No space left on device' error directly points to insufficient EBS volume size.
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 training data size exceeds the available EBS volume size
The error message in the exhibit indicates an 'OSError: [Errno 28] No space left on device' during the training job. This occurs when the training data size exceeds the available EBS volume size attached to the SageMaker training instance. SageMaker uses EBS volumes for storing training data and intermediate outputs; if the dataset is larger than the provisioned EBS storage, the job fails with this specific disk-full error.
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 learning rate is too high
Why it's wrong here
Learning rate would not cause a file system error.
- ✗
The instance type does not have SSD storage
Why it's wrong here
The log says 'Retrying with local SSD...', implying the instance may have SSD, but it still failed.
- ✗
The instance type does not have enough memory
Why it's wrong here
Memory issues would typically cause out-of-memory errors, not scratch space errors.
- ✓
The training data size exceeds the available EBS volume size
Why this is correct
The error 'No usable scratch space' indicates disk space exhaustion on the EBS volume.
- ✗
The number of epochs is too low
Why it's wrong here
Epoch number would not cause a scratch space error.
