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 company is using AWS CloudFormation to deploy infrastructure. Which method ensures that sensitive data, such as database passwords, is not exposed in the template or outputs?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a dynamic reference to a Systems Manager Parameter Store parameter.
Using dynamic references to AWS Systems Manager Parameter Store or Secrets Manager keeps secrets out of templates. Option B is correct. Hardcoding (A) exposes secrets. Outputs (C) are visible. NoEcho (D) hides in console but not from API.
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.
✗
Use the 'NoEcho' property on the password parameter.
Why it's wrong here
NoEcho hides input but the value may still be in template.
✗
Store the password in the template outputs.
Why it's wrong here
Outputs are visible to anyone with access.
✗
Hardcode the password in the template and use the 'NoEcho' property.
Why it's wrong here
Hardcoding is not secure even with NoEcho.
✓
Use a dynamic reference to a Systems Manager Parameter Store parameter.
Why this is correct
Dynamic references retrieve secrets securely.
