A company uses AWS CloudTrail to log API calls across all regions. The SysOps administrator notices that logs for a specific region are missing from the centralized S3 bucket. What is the most likely cause?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
The CloudTrail trail is not enabled for that region.
Correct. CloudTrail must be explicitly enabled for each region or a multi-region trail must be used. Missing logs for a specific region strongly suggests the trail is not applied there.
B
Distractor review
The S3 bucket policy denies write access from CloudTrail for that region.
Incorrect. A bucket policy denying CloudTrail writes would affect all regions, not a single region.
C
Distractor review
CloudTrail log file validation is disabled.
Incorrect. Log file validation is a security feature to ensure integrity; it does not cause missing logs.
D
Distractor review
The IAM role for CloudTrail does not have permissions to write logs from that region.
Incorrect. IAM roles for CloudTrail are not region-specific; permission issues would affect all regions.
Common exam trap
Common exam trap: answer the scenario, not the keyword
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.
Technical deep dive
How to think about this question
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.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Question 1
A company uses Amazon CloudFront to deliver content to a global audience. The origin is an Application Load Balancer in us-east-1. The SysOps administrator wants to reduce costs by minimizing the number of requests that reach the origin server. Which action should the administrator take?
Question 2
A company runs a batch processing application on Amazon EC2 that runs for 2 hours every night. The workload can tolerate interruptions. Which EC2 purchasing option provides the lowest cost for this use case?
Question 3
A SysOps administrator needs to monitor the CPU utilization of an Amazon RDS DB instance and receive an alarm when CPU utilization exceeds 80% for 5 consecutive minutes. Which AWS service should be used to create this alarm?
Question 4
A company runs a critical web application on Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). The application uses session stickiness (sticky sessions) to maintain user sessions. The SysOps administrator notices that when instances are replaced during a scale-in or failure event, users lose their session data. The administrator needs to preserve session data across instance failures without losing stickiness benefits. What should the administrator do?
Question 5
A company runs a production web application on a single Amazon EC2 instance. The application experiences a predictable and steady workload 24/7. The SysOps administrator wants to minimize compute costs for this instance while ensuring it remains available during the expected workload. Which EC2 purchasing option should the administrator use?
Question 6
A company has a VPC with public and private subnets. The private subnets host application servers that need to make outbound HTTPS connections to the internet. The SysOps administrator must implement a solution that provides outbound internet connectivity while preventing inbound connections from the internet. Additionally, the solution must allow the company to control which domains the application servers can access. Which solution should the administrator implement?
FAQ
Questions learners often ask
What does this SOA-C02 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: The CloudTrail trail is not enabled for that region. — CloudTrail can be configured as a single-region trail or a multi-region trail. If logs are missing for a specific region, it indicates that the trail was not applied to that region. A multi-region trail applies to all regions, while a single-region trail only captures events in the region where it was created. Other options like S3 bucket policy, log file validation, or IAM roles could cause delivery failures but are less likely to affect only one region.
