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.
A SysOps admin needs to set up centralized logging for multiple AWS accounts. Which TWO services should be used together to aggregate logs into a single S3 bucket? (Choose 2.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Config
AWS Config and AWS CloudTrail are the correct pair because CloudTrail records API activity across accounts, and AWS Config records resource configuration changes. Both can be configured to deliver log files to a centralized S3 bucket by setting up a trail (CloudTrail) or a delivery channel (Config) that points to the same bucket, often using a bucket policy that grants cross-account write permissions. This enables aggregated logging for multiple AWS accounts in a single S3 bucket.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Amazon VPC Flow Logs
Why it's wrong here
Flow logs can be published to S3 but are not typically used for multi-account aggregation.
✓
AWS Config
Why this is correct
Config can deliver configuration history and snapshots to a central S3 bucket.

✓
AWS CloudTrail
Why this is correct
CloudTrail can be configured to deliver logs to a central S3 bucket across accounts.

✗
Amazon S3 cross-region replication
Why it's wrong here
Replication is for copying objects, not initial log delivery.
✗
Amazon CloudWatch Logs subscription filter
Why it's wrong here
Subscription filters send logs to Kinesis or Lambda, not directly to S3.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse log delivery services (CloudTrail, Config) with log generation services (VPC Flow Logs) or data movement services (S3 replication, CloudWatch subscription filters), failing to recognize that only CloudTrail and Config natively support direct cross-account S3 delivery without additional infrastructure.
Detailed technical explanation
How to think about this question
Under the hood, CloudTrail uses a trail object that defines the S3 bucket and optional prefix for log delivery, and it supports cross-account delivery via a bucket policy that grants the CloudTrail service principal (cloudtrail.amazonaws.com) write access. AWS Config similarly uses a delivery channel that writes configuration snapshots and history to an S3 bucket, and it can be configured with a bucket policy that allows the Config service principal (config.amazonaws.com) from other accounts to deliver logs. A real-world scenario is a multi-account organization using AWS Organizations, where a centralized logging account hosts the S3 bucket, and each member account's CloudTrail and Config are configured to deliver to that bucket, enabling security auditing and compliance monitoring across the entire organization.

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.
