The correct answer is to add 'DeletionProtection': true to the Properties block of the AWS::RDS::DBInstance resource. This works because DeletionProtection is a valid property of the RDS DB instance resource in CloudFormation, which when set to true prevents the database from being deleted via the console, CLI, or API—including during stack deletion. On the AWS Certified Database Specialty DBS-C01 exam, this question tests your ability to distinguish between CloudFormation attributes like DeletionPolicy (which controls what happens to a resource when the stack is deleted) and resource-specific properties like DeletionProtection. A common trap is confusing DeletionPolicy with DeletionProtection: remember that DeletionPolicy is a top-level attribute on any resource, while DeletionProtection is a property nested under Properties and is unique to RDS. For a quick memory tip, think “Protection goes in Properties, Policy is an attribute”—the alliteration helps you keep them straight on exam day.
DBS-C01 Management and Operations Practice Question
This DBS-C01 practice question tests your understanding of management and operations. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 DBA deploys this CloudFormation stack. After creation, the DBA needs to enable deletion protection for the DB instance. Which modification to the template would accomplish this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add 'DeletionProtection': true to the Properties.
Option D is correct. Adding DeletionProtection: true enables deletion protection. Option A is wrong because DeletionPolicy is a CloudFormation attribute, not a property. Option B is wrong because PreventRDSDeletion is not a valid property. Option C is wrong because the syntax is incorrect.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
