Quick Answer
The answer is AWS CloudTrail and Amazon CloudWatch Logs used together. CloudTrail is the correct service because it records every API call made to AWS services, capturing who made the call, when, and from which source, which is essential for auditing all AWS API activity in an SAP environment. CloudWatch Logs then stores, monitors, and analyzes these log streams, allowing you to set up alarms or search for specific API events. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this pairing tests your understanding of audit logging requirements for regulated SAP workloads, often appearing in questions that distinguish CloudTrail from AWS Config (which tracks resource configuration changes, not API calls) or VPC Flow Logs (which capture network traffic, not API activity). A common trap is selecting Amazon S3 for storage alone, but the question explicitly asks for two services that work together to log and analyze API calls, making CloudWatch Logs the necessary companion. Memory tip: think of CloudTrail as the camera recording every API action, and CloudWatch Logs as the security guard reviewing the footage.
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 SAP on AWS and needs to ensure that all API calls made to AWS services are logged for auditing purposes. Which TWO services should be used together to achieve this?
Amazon S3
Why wrong: S3 is a storage service, but the combination is CloudTrail + CloudWatch Logs.
VPC Flow Logs
Why wrong: Flow logs capture network traffic, not API calls.
Amazon CloudWatch Logs
CloudWatch Logs can store and analyze CloudTrail logs.
AWS Config
Why wrong: Config records resource configurations, not API calls.
AWS CloudTrail
CloudTrail records API calls.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon CloudWatch Logs
Option A is correct because AWS CloudTrail logs API calls. Option D is correct because Amazon CloudWatch Logs can store and analyze the logs. Option B is wrong because AWS Config records resource configurations, not API calls. Option C is wrong because VPC Flow Logs are for network traffic. Option E is wrong because Amazon S3 can store logs, but the question asks for services used together.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Amazon S3
Why it's wrong here
S3 is a storage service, but the combination is CloudTrail + CloudWatch Logs.
VPC Flow Logs
Why it's wrong here
Flow logs capture network traffic, not API calls.
Amazon CloudWatch Logs
Why this is correct
CloudWatch Logs can store and analyze CloudTrail logs.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Variation 1. A company runs SAP on AWS and wants to ensure that all API calls to create, modify, or delete EC2 instances are logged for auditing. Which TWO AWS services can be used together to achieve this? (Choose two.)
easyWhy A: Options A and C are correct. AWS CloudTrail logs API calls. Amazon CloudWatch Logs can store the logs for analysis. Option B (VPC Flow Logs) captures network traffic, not API calls. Option D (AWS Config) tracks configuration changes but not all API calls. Option E (S3 server access logs) logs access to S3 buckets.
