The correct answer is that the script runs every time the notebook is started. This is because SageMaker lifecycle configurations are shell scripts that execute during the instance’s boot process, specifically after the instance transitions from a stopped state to a running state. Unlike user-level scripts triggered by kernel events, lifecycle configurations hook into the EC2 instance lifecycle, meaning they fire on every start, stop-and-start, or initial launch, but not on kernel resets or terminal restarts. On the AWS Certified Machine Learning Engineer Associate MLA-C01 exam, this question tests your understanding of the distinction between instance-level and environment-level automation—a common trap is confusing lifecycle configurations with conda or Jupyter hooks that run per kernel. To remember, think of lifecycle configurations as the “engine ignition” of the notebook: they run each time you turn the car on, not each time you shift gears.
MLA-C01 ML Model Development Practice Question
This MLA-C01 practice question tests your understanding of ml model development. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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
#!/bin/bash
set -e
cd /home/ec2-user/SageMaker
git clone https://github.com/org/repo.git
pip install -r requirements.txt
Refer to the exhibit. A user launches a SageMaker notebook instance with this lifecycle configuration. What happens?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The script runs every time the notebook is started
SageMaker lifecycle configurations run every time the notebook instance is started (including after stop and start). They do not run only on first start or after kernel resets.
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 script runs every time the notebook is started
Why this is correct
Lifecycle configurations execute on each instance start event.
Related concept
Read the scenario before looking for a memorised answer.
✗
The script runs after each kernel reset
Why it's wrong here
Kernel resets do not trigger lifecycle configurations.
✗
The script runs only on the first start
Why it's wrong here
They run on every start, not just the first.
✗
The script runs only when creating the instance
Why it's wrong here
Creation is a start event, but subsequent starts also trigger the script.
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.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
