MLA-C01 Practice Question: A SageMaker training job has been running for…
A SageMaker training job has been running for several hours but shows no progress. The job is using a custom Docker container. The engineer suspects a bug in the training script. Which tool is BEST to debug the training job without stopping it?
⚠ Common exam trap
It's easy for candidates to confuse Debugger with Profiler, assuming both are for debugging, but Profiler is strictly for performance optimization, not for diagnosing training script bugs like infinite loops or incorrect tensor values.

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
✓
SageMaker Debugger
SageMaker Debugger is the best tool because it can monitor and debug training jobs in real time without stopping them. It captures tensors, gradients, and other internal state from the training script, allowing you to inspect issues like vanishing gradients or infinite loops while the job continues running. This is ideal for diagnosing a suspected bug in a custom Docker container without interrupting the training process.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon CloudWatch Logs
Why it's wrong here
CloudWatch Logs show output but not interactive debugging or detailed internal state.
- ✗
SageMaker Local Mode
Why it's wrong here
Local mode is for testing locally before cloud training, not for debugging an already running job.
- ✗
SageMaker Processing
Why it's wrong here
Processing is a different job type, not for debugging running training.
- ✓
SageMaker Debugger
Why this is correct
Correct. Debugger provides real-time debugging, monitoring, and profiling capabilities.
- ✗
SageMaker Profiler
Why it's wrong here
Profiler focuses on performance and resource utilization, not script bugs.
