Quick Answer
The answer is AWS CloudTrail. CloudTrail is the correct service for monitoring failed console login attempts because it records all AWS Management Console sign-in events as CloudTrail events, specifically capturing the ConsoleLogin event type with a status of “Failure” when authentication fails. This works because CloudTrail logs API activity across your AWS account, and console logins are essentially API calls to the AWS authentication service. On the AWS Certified Security Specialty SCS-C02 exam, this question tests your ability to distinguish between logging services: a common trap is confusing CloudTrail with CloudWatch Logs, but remember that CloudWatch Logs is a destination for logs, not a source of login events. Similarly, S3 access logs track object-level access, and VPC Flow Logs track network traffic—neither captures user authentication attempts. For the exam, a useful memory tip is “Console logins are CloudTrail’s trail,” meaning any sign-in event, successful or failed, is always recorded by CloudTrail, not by other services.
This SCS-C02 practice question tests your understanding of security logging and monitoring. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 security analyst wants to monitor unsuccessful login attempts to the AWS Management Console. Which AWS service and log combination should be used?
Amazon S3 server access logs.
Why wrong: S3 access logs record requests to S3 buckets, not console logins.
VPC Flow Logs.
Why wrong: VPC Flow Logs capture network traffic, not console logins.
Amazon CloudWatch Logs.
Why wrong: CloudWatch Logs is a destination for logs, not a source of login events.
AWS CloudTrail.
CloudTrail records API calls, including ConsoleLogin events.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
AWS CloudTrail.
AWS CloudTrail logs console sign-in events, including failed attempts. The ConsoleLogin event with a failure status is logged. Option A is wrong because S3 access logs track object-level access. Option B is wrong because VPC Flow Logs track network traffic. Option C is wrong because CloudWatch Logs is a destination, not a source of login events.
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.
Amazon S3 server access logs.
Why it's wrong here
S3 access logs record requests to S3 buckets, not console logins.
VPC Flow Logs.
Why it's wrong here
VPC Flow Logs capture network traffic, not console logins.
Amazon CloudWatch Logs.
Why it's wrong here
CloudWatch Logs is a destination for logs, not a source of login events.
AWS CloudTrail.
Why this is correct
CloudTrail records API calls, including ConsoleLogin events.
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 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.
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 SCS-C02 NAT questions on configuration and troubleshooting.
