MLA-C01 Practice Question: ML Solution Monitoring, Maintenance and Security

This MLA-C01 practice question tests your understanding of ml solution monitoring, maintenance and security. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A startup is using SageMaker to train a deep learning model. They use GPU instances for training. The training job takes about 8 hours. The team notices that sometimes the training job fails with an error message indicating that the instance was terminated due to Amazon EBS volume underprovisioned. The team is using the default EBS volume size for the training instance. They want to avoid this error without over-provisioning. What should they do?

A
Mount an Amazon EFS file system to the training instance and store all data there.
Why wrong: EFS adds network latency and may not be as fast as local EBS for read/write intensive training.
B
Switch to compute-optimized (C5) instances to reduce storage usage.
Why wrong: Instance type doesn't affect EBS volume size; C5 has similar storage options.
C
Specify a larger EBS volume size in the training job's resource configuration.
Increasing the volume size ensures sufficient space for data and checkpoints.
D
Configure the training job to use Amazon FSx for Lustre as a scratch file system.
Why wrong: FSx for Lustre is for high-performance computing, but it's more complex and may not be necessary.

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

✓

Specify a larger EBS volume size in the training job's resource configuration.

Option C is correct because specifying a larger EBS volume size in the training job's resource configuration ensures that the instance has sufficient storage for the dataset, intermediate checkpoints, and logs, preventing the 'EBS volume underprovisioned' error. Option A (mount Amazon EFS) adds network latency and complexity; it does not address the root cause of insufficient local storage. Option B (switch to C5 instances) does not increase storage capacity; it changes the instance type but storage is separate. Option D (use FSx for Lustre) is a high-performance file system but is overkill for simple storage needs and requires additional setup and cost.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Similar concept trap
Instance type doesn't affect EBS volume size; C5 has similar storage options.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
