Track AWS Resource Changes and SSH Alerts with CloudTrail for SAP

This PAS-C01 practice question tests your understanding of technology. 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.

An SAP administrator needs to ensure that all changes to an SAP system's AWS resources are tracked and that alerts are sent when SSH access to EC2 instances is modified. Which AWS service should be used?

Answer choices

Why each option matters

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 is the correct service because it records API activity across your AWS infrastructure, including changes to EC2 security groups that control SSH access. By enabling CloudTrail, you can monitor for events like AuthorizeSecurityGroupIngress and trigger alerts via CloudWatch Events or Lambda when SSH (port 22) rules are modified, meeting the audit and alerting requirements.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 Config

    Why it's wrong here

    Tracks configuration changes, not API calls.

  • Amazon CloudWatch

    Why it's wrong here

    Monitors metrics and logs.

  • AWS Trusted Advisor

    Why it's wrong here

    Provides recommendations, not auditing.

  • AWS CloudTrail

    Why this is correct

    Records API calls for auditing.

Common exam traps

Common exam trap: answer the scenario, not the keyword

A common trap in AWS SAP on AWS Specialty exams is confusing AWS Config (which tracks configuration state and compliance) with AWS CloudTrail (which records API calls). This question specifically requires tracking API modifications (e.g., changes to security group rules for SSH) and sending alerts, which is a CloudTrail capability, not just configuration compliance.

Detailed technical explanation

How to think about this question

CloudTrail captures all management events, including EC2 API calls like RevokeSecurityGroupIngress and AuthorizeSecurityGroupIngress, and stores them in a log file or delivers them to CloudWatch Logs. You can then create a CloudWatch Events rule that matches the specific event name and triggers an SNS notification or Lambda function for real-time alerting. A subtle behavior is that CloudTrail can be configured to log data events (e.g., S3 object-level operations) but for security group changes, management events are sufficient and enabled by default in most regions.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • 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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. An SAP administrator needs to ensure that all API calls made to AWS services by the SAP system are logged for auditing purposes. Which AWS service should be enabled?

easy
  • A.AWS Config
  • B.AWS CloudTrail
  • C.Amazon CloudWatch
  • D.VPC Flow Logs

Why B: AWS CloudTrail is the correct service because it records all API calls made to AWS services, including the caller identity, time, source IP, and request parameters. For SAP systems requiring audit logs of AWS interactions, CloudTrail provides the necessary event history for security analysis, resource change tracking, and compliance auditing.
