This DOP-C02 practice question tests your understanding of monitoring and logging. 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.
A DevOps engineer needs to centralize logs from multiple AWS accounts into a single CloudWatch Logs account. Which feature should be used?
CloudWatch Logs Insights
Why wrong: Insights is for querying logs, not cross-account delivery.
AWS CloudTrail
Why wrong: CloudTrail captures API calls, not all logs.
Amazon Kinesis Data Firehose
Why wrong: Firehose can deliver logs but requires cross-account setup; not the primary feature.
CloudWatch Logs cross-account subscription
This feature allows sending log groups from source accounts to a central destination.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
CloudWatch Logs cross-account subscription
CloudWatch Logs cross-account subscription (Option D) allows you to stream log data from multiple source AWS accounts to a single destination account's CloudWatch Logs log group. This is the native, managed feature designed specifically for centralizing logs across accounts without needing additional infrastructure or data transformation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
CloudWatch Logs Insights
Why it's wrong here
Insights is for querying logs, not cross-account delivery.
AWS CloudTrail
Why it's wrong here
CloudTrail captures API calls, not all logs.
Amazon Kinesis Data Firehose
Why it's wrong here
Firehose can deliver logs but requires cross-account setup; not the primary feature.
CloudWatch Logs cross-account subscription
Why this is correct
This feature allows sending log groups from source accounts to a central destination.

Common exam traps
The trap here is that candidates often confuse CloudWatch Logs Insights (a query tool) with the actual cross-account log forwarding mechanism, or they incorrectly assume that CloudTrail or Kinesis Data Firehose are the primary services for cross-account log centralization, when in fact the native CloudWatch Logs cross-account subscription is the correct, managed solution.
Detailed technical explanation
CloudWatch Logs cross-account subscription works by creating a subscription filter in the source account's log group that sends log events to a destination log group in the target account, using a destination policy that grants the source account permissions. Under the hood, this uses the PutSubscriptionFilter API with a destinationArn pointing to the target log group, and the target account must have a resource policy allowing the source account to write. A real-world scenario is a multi-account AWS Organization where security teams need to aggregate all application logs into a centralized SIEM or monitoring account without deploying agents in each account.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
