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.
Refer to the exhibit. An IAM policy is attached to a user to allow invoking a SageMaker endpoint. A developer tries to call the endpoint from a laptop with IP 203.0.113.5 and receives an access denied error. What is the most likely reason?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The condition restricts the IP address to the 10.0.0.0/8 range.
The policy includes a condition that restricts the source IP address to the 10.0.0.0/8 private range. The developer's laptop has a public IP of 203.0.113.5, which does not fall within that range, so the condition fails and access is denied. This is the most likely reason for the error because the condition explicitly blocks requests from outside the specified private network.
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.
✗
The resource ARN is incorrect.
Why it's wrong here
The ARN appears correctly formatted.
✓
The condition restricts the IP address to the 10.0.0.0/8 range.
Why this is correct
The condition enforces that source IP must be in 10.0.0.0/8, but the laptop IP is not.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The user does not have permission to assume the SageMaker role.
Why it's wrong here
The policy is attached directly to the user, no role assumption is needed.
✗
The policy does not include access to the API action.
Why it's wrong here
The policy does include sagemaker:InvokeEndpoint.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may overlook the condition element and assume the error is due to a missing action or incorrect ARN, when in fact the condition is the restrictive factor that denies access based on the source IP.
Detailed technical explanation
How to think about this question
The condition uses the 'aws:SourceIp' key with the 'IpAddress' operator, which evaluates the source IP of the request against the specified CIDR range. If the request originates from outside that range, the condition fails and the entire statement is denied, even if the action and resource match. In real-world scenarios, this is commonly used to enforce network-level access control for sensitive endpoints, but it can inadvertently block legitimate users if their IP is not included in the allowed range.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
