- A
CloudTrail logs are being delivered to an S3 bucket, not to CloudWatch Logs.
Why wrong: CloudTrail lookup-events queries the event history, regardless of delivery destination.
- B
The command is run in the wrong AWS Region.
Why wrong: RunInstances is a regional event; if the region is correct, it should show.
- C
CloudTrail is not configured to log management events.
If management events are not logged, RunInstances won't appear.
- D
The IAM user does not have permission to view CloudTrail events.
Why wrong: Permission errors would return an access denied error, not empty events.
Quick Answer
The answer is that CloudTrail is not configured to log management events. This is correct because CloudTrail can be independently enabled for management events, data events, or both; if only data events are logged, API calls like RunInstances—which are management events—will never appear in the event history queried by `aws cloudtrail lookup-events`. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your understanding that CloudTrail’s default trail logs management events, but a custom trail may omit them, and the common trap is assuming all API activity is automatically recorded. A reliable memory tip is “Management events manage the house; data events work inside the rooms”—if you only log data events, you won’t see who opened the front door.
SOA-C02 Monitoring, Logging, and Remediation Practice Question
This SOA-C02 practice question tests your understanding of monitoring, logging, and remediation. 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.
Refer to the exhibit. The command returns no events for RunInstances during the specified time period. The administrator knows that instances were launched during that time. What is the most likely cause?

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
CloudTrail is not configured to log management events.
Option C is correct because CloudTrail can be configured to log either management events, data events, or both. If only data events are logged, management events such as RunInstances will not appear in the CloudTrail event history. The command `aws cloudtrail lookup-events` queries the CloudTrail event history, which only contains events that CloudTrail is configured to record. Since the administrator knows instances were launched but no events are returned, the most likely cause is that CloudTrail is not configured to log management events.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume CloudTrail always logs all API calls by default, but they overlook that CloudTrail can be configured to exclude management events, and the `lookup-events` command only returns events that CloudTrail is actually recording.

RunInstances is a regional event; if the region is correct, it should show.
Detailed technical explanation
How to think about this question
CloudTrail management events include operations like RunInstances, TerminateInstances, and CreateVpc, and are enabled by default when you create a trail. However, if a trail is created with the 'Read/Write events' set to 'None' or if the trail is configured to log only data events (e.g., S3 object-level operations), management events are not recorded. The `lookup-events` API returns events from the CloudTrail event history, which is a regional service that stores the last 90 days of events based on the trail's configuration. In a multi-account or multi-region setup, a single trail can aggregate events, but the lookup must be performed in the region where the trail is configured to deliver events.
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 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.
