The answer is that the IAM policy’s condition on `TrainingJobStatus` causes the access denied error because it only permits `CreateTrainingJob` when the status equals `Failed`, which is never true at the moment of creation. When a SageMaker training job is initiated, its status is initially `Creating` or `InProgress`, not `Failed`, so the condition evaluates to false and the API call is denied. This question tests your understanding of how IAM condition keys interact with SageMaker API lifecycle states—a common trap on the AWS Certified Machine Learning Specialty MLS-C01 exam where candidates overlook that a condition referencing a post-creation status will block the initial request. The key insight is that `sagemaker:TrainingJobStatus` is a resource-level condition that only applies after the job exists, making it useless for authorizing creation. Memory tip: think of it as a “chicken-and-egg” problem—you can’t check a status that hasn’t been set yet.
MLS-C01 Modeling Practice Question
This MLS-C01 practice question tests your understanding of modeling. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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. A data scientist is trying to create a SageMaker training job but receives an access denied error. The IAM policy shown is attached to their role. What is the most likely reason for the error?

Correct answer & explanation
✓
The policy only allows CreateTrainingJob when the training job status is 'Failed', which is never true initially
Option A is correct because the IAM policy uses a `Condition` block with `sagemaker:TrainingJobStatus` set to `Failed`. When a `CreateTrainingJob` API call is made, the training job status is not yet set (it is `Creating` or `InProgress`), so the condition evaluates to false, and the request is denied. The policy only grants permission when the status equals `Failed`, which never occurs at creation time.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
The Action is not allowed because 'CreateTrainingJob' is misspelled
Why it's wrong here
It is correctly spelled.
✗
There is an explicit deny in another policy
Why it's wrong here
No evidence.
✗
The Resource is set to '*' which does not include the specific training job ARN
Why it's wrong here
'*' includes all resources.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the nuance that IAM condition keys like `sagemaker:TrainingJobStatus` are evaluated against the current state of the resource at the time of the API call, and candidates mistakenly assume a wildcard resource or a missing action is the issue rather than a condition that never matches.
Detailed technical explanation
How to think about this question
The `sagemaker:TrainingJobStatus` condition key is evaluated at the time of the API call, and for `CreateTrainingJob`, the status is not yet defined (it is `Creating`). AWS IAM policies with conditions are evaluated strictly; if the condition key does not exist or does not match, the request is denied. In real-world scenarios, such conditions are used to allow actions only on failed jobs (e.g., to retry or clone them), but they must be paired with other conditions or actions to allow initial creation.

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.
