MLA-C01 Practice Question: Refer to the exhibit

Exhibit

{
    "TrainingJobName": "job-123",
    "TrainingJobStatus": "Failed",
    "FailureReason": "ClientError: Review the error message. Training failed due to insufficient instance memory.",
    "AlgorithmSpecification": {
        "TrainingImage": "123456789012.dkr.ecr.us-east-1.amazonaws.com/sagemaker-xgboost:1.0-1",
        "TrainingInputMode": "File"
    },
    "ResourceConfig": {
        "InstanceType": "ml.m5.large",
        "InstanceCount": 1,
        "VolumeSizeInGB": 30
    }
}

Refer to the exhibit. A SageMaker training job failed. Based on the error message, which action should the engineer take?

⚠ Common exam trap

It's easy for candidates to confuse 'out of memory' with 'out of disk space' and incorrectly choose to increase the volume size (Option C), but the error is specifically about RAM exhaustion, not storage.

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

✓

Use a larger instance type

The error message indicates that the training job failed due to insufficient memory (an out-of-memory error). Using a larger instance type (Option B) provides more RAM, which directly resolves the memory exhaustion issue. SageMaker training jobs run on EC2 instances, and the instance type determines the available memory and compute resources.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
Change the algorithm
Why it's wrong here
The algorithm is not the cause; memory insufficiency is hardware-related.
✓
Use a larger instance type
Why this is correct
A larger instance type has more memory, addressing the out-of-memory error.
✗
Increase the volume size
Why it's wrong here
Volume size is for storage, not memory.
✗
Increase the instance count
Why it's wrong here
Adding more instances does not increase memory per instance; the job runs on a single instance.
