This DVA-C02 practice question tests your understanding of development with aws services. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 developer is implementing a solution to store application logs from multiple EC2 instances. The logs must be stored in a centralized location for analysis. Which services can the developer use to achieve this? (Choose TWO.)
Amazon CloudWatch Logs
CloudWatch Logs can collect and store logs from EC2 instances.
AWS CloudTrail
Why wrong: CloudTrail logs API calls, not application logs.
Amazon Kinesis Data Analytics
Why wrong: Kinesis Data Analytics processes streaming data, not storage.
Amazon DynamoDB
Why wrong: DynamoDB is not designed for log storage.
Amazon S3
S3 can be used as a centralized log storage.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon CloudWatch Logs
Option A is correct because CloudWatch Logs can aggregate logs from EC2 instances via the CloudWatch agent. Option C is correct because S3 can store log files as a centralized repository. Option B is wrong because CloudTrail is for API activity, not application logs. Option D is wrong because DynamoDB is not optimized for log storage. Option E is wrong because Kinesis Data Analytics processes streams, not stores logs.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
