The correct answer is AWS CloudTrail and AWS Config because CloudTrail captures every API call made within your AWS account, while AWS Config continuously records resource configuration changes and evaluates them against desired policies. Together, they form a comprehensive audit trail for SAP on AWS with CloudTrail and AWS Config, covering both who did what and what changed over time. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this pairing tests your understanding that auditing requires both activity logging and configuration tracking—a common trap is confusing monitoring services like CloudWatch or Systems Manager with audit-specific tools. Remember, CloudTrail tracks the “who, what, when” of API actions, and Config tracks the “what changed” in resource states; think of them as the audit duo. A useful memory tip: “Trail for the tale of actions, Config for the state of things.”
PAS-C01 Operations and Maintenance Practice Question
This PAS-C01 practice question tests your understanding of operations and maintenance. 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 runs its SAP environment on AWS and needs to ensure that all changes to the SAP landscape are tracked for auditing. The environment includes EC2 instances, RDS databases, and Lambda functions. Which combination of AWS services provides the most comprehensive audit trail?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS CloudTrail and AWS Config
Option B is correct because CloudTrail logs API calls for all services, and AWS Config records resource configuration changes, together providing a complete audit trail. Option A is wrong because CloudWatch Logs and Metrics are for monitoring, not auditing changes. Option C is wrong because Systems Manager Inventory collects software inventory, not configuration changes. Option D is wrong because VPC Flow Logs capture network traffic, not configuration changes.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
AWS Systems Manager Inventory and AWS Config
Why it's wrong here
Inventory is for software inventory, not full configuration changes.
✓
AWS CloudTrail and AWS Config
Why this is correct
CloudTrail logs API calls; Config records resource configuration changes.
Related concept
Static NAT maps one inside address to one outside address.
✗
Amazon VPC Flow Logs and AWS CloudTrail
Why it's wrong here
Flow logs capture network traffic, not resource changes.
✗
Amazon CloudWatch Logs and Amazon CloudWatch Metrics
Why it's wrong here
Logs and metrics are for monitoring, not auditing changes.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
What to study next
Got this wrong? Here's your next step.
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 PAS-C01 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: AWS CloudTrail and AWS Config — Option B is correct because CloudTrail logs API calls for all services, and AWS Config records resource configuration changes, together providing a complete audit trail. Option A is wrong because CloudWatch Logs and Metrics are for monitoring, not auditing changes. Option C is wrong because Systems Manager Inventory collects software inventory, not configuration changes. Option D is wrong because VPC Flow Logs capture network traffic, not configuration changes.
