Quick Answer
The answer is AWS CloudFormation Drift Detection, a native feature that directly compares the actual state of your deployed resources against the intended template configuration. This service works by taking a baseline of the stack’s template and then performing a detailed comparison of each resource’s live properties, flagging any discrepancies such as manual changes or external modifications. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your ability to distinguish between CloudFormation’s built-in drift detection and other management tools like AWS Config or Systems Manager, which serve different purposes. A common trap is confusing drift detection with Config rules—remember that drift detection is specifically a CloudFormation stack operation, not a general compliance check. For a quick memory tip, think “CFN Drift = Stack vs. Template,” emphasizing that it’s the template, not a rule set, that defines the baseline.
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. 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.
A company uses AWS CloudFormation to manage infrastructure. They want to detect drift from the intended template configuration. Which service should they use?
AWS Config
Why wrong: AWS Config can evaluate compliance, but CloudFormation has its own drift detection feature.
AWS Service Catalog
Why wrong: Service Catalog is for managing approved products, not drift detection.
AWS CloudTrail
Why wrong: CloudTrail logs API calls, not configuration drift.
CloudFormation Drift Detection
CloudFormation Drift Detection directly compares stack resources to the template.
Answer choices

Correct answer & explanation
CloudFormation Drift Detection
AWS CloudFormation Drift Detection is a native feature that compares the actual resource configuration with the template. Option A is correct. Options B, C, and D are other services but not specifically for CloudFormation drift detection.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Config
Why it's wrong here
AWS Config can evaluate compliance, but CloudFormation has its own drift detection feature.
AWS Service Catalog
Why it's wrong here
Service Catalog is for managing approved products, not drift detection.
AWS CloudTrail
Why it's wrong here
CloudTrail logs API calls, not configuration drift.
CloudFormation Drift Detection
Why this is correct
CloudFormation Drift Detection directly compares stack resources to the template.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related SAP-C02 NAT questions on configuration and troubleshooting.
