DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. 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.
A financial services company uses AWS CloudFormation to deploy a three-tier web application. The stack includes an Amazon RDS for PostgreSQL database. The database master password is stored in AWS Secrets Manager, and the CloudFormation template uses a dynamic reference to retrieve it during stack creation. The team recently rotated the database password in Secrets Manager. When they attempt to update the stack to change other parameters, the update fails with the error: 'Value of property MasterUserPassword must be a string.' The team is using the following template snippet for the password: 'MasterUserPassword': '{{resolve:secretsmanager:MySecret:SecretString:password}}'. The stack was originally created with AWS CloudFormation. What is the most likely cause of the failure?
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.
The secret was rotated before the stack was created, causing a mismatch.
Why wrong: The stack was created with the original secret.
B
The template syntax is incorrect; it should use '{{resolve:secretsmanager:MySecret:SecretString:password}}' with different quotes.
Why wrong: The syntax is valid.
C
Dynamic references in CloudFormation are only resolved at stack creation, not during updates. The team must use a different method to reference the rotated password.
CloudFormation does not re-resolve dynamic secrets on stack updates.
D
The secret is in a different region than the stack.
Why wrong: The error message indicates a syntax issue, not a region mismatch.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Dynamic references in CloudFormation are only resolved at stack creation, not during updates. The team must use a different method to reference the rotated password.
Option A is correct because dynamic references are only resolved during stack creation and not during updates. To update the password, the team must use a different approach. Option B is incorrect because Secrets Manager rotation does not invalidate the secret immediately. Option C is incorrect because the template syntax is correct. Option D is incorrect because Secrets Manager is not region-bound in this context.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 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.
