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.
Exhibit
2024-01-01 12:00:00 ERROR - Baseline configuration is missing for data quality monitoring. Unable to evaluate constraints.
2024-01-01 12:00:01 ERROR - Monitoring job failed.
Refer to the exhibit. A team receives an error when running a SageMaker Model Monitor schedule for data quality. What should they do to resolve this issue?
Exhibit
2024-01-01 12:00:00 ERROR - Baseline configuration is missing for data quality monitoring. Unable to evaluate constraints.
2024-01-01 12:00:01 ERROR - Monitoring job failed.
A
Update the IAM role to allow S3 access
Why wrong: The error is about missing baseline, not permissions.
B
Restart the monitoring schedule
Why wrong: Restarting will encounter the same error.
C
Enable data capture on the endpoint
Why wrong: Data capture is needed for monitoring but does not provide the baseline.
D
Create a baseline job using the training dataset
A baseline must be generated from training data to compare inference data against.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a baseline job using the training dataset
The error occurs because SageMaker Model Monitor requires a baseline to compare against live data. Without a baseline job created from the training dataset, the monitoring schedule fails. Option D resolves this by generating the necessary statistics and constraints that define expected data quality.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Update the IAM role to allow S3 access
Why it's wrong here
The error is about missing baseline, not permissions.
✗
Restart the monitoring schedule
Why it's wrong here
Restarting will encounter the same error.
✗
Enable data capture on the endpoint
Why it's wrong here
Data capture is needed for monitoring but does not provide the baseline.
✓
Create a baseline job using the training dataset
Why this is correct
A baseline must be generated from training data to compare inference data against.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume the error is a permissions or configuration issue (S3 access or data capture), but the root cause is the mandatory prerequisite of a baseline job before a monitoring schedule can run.
Detailed technical explanation
How to think about this question
SageMaker Model Monitor uses a baseline job to compute statistics (e.g., mean, stddev) and constraints (e.g., min, max) from the training dataset, stored in S3 under the monitoring output path. The monitoring schedule then compares live inference data against these constraints using a built-in container that runs statistical tests like z-score or distribution distance. Without this baseline, the schedule has no reference to detect drift, causing the error.
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.
TExam Day Tips
→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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
