The answer is Amazon CloudWatch Logs and CloudWatch Logs Insights. CloudWatch Logs uses the unified CloudWatch agent on EC2 instances to collect and forward log data from local disk to a centralized log group, requiring minimal configuration beyond installing the agent. CloudWatch Logs Insights then enables you to query, filter, and analyze that aggregated log data at scale using a purpose-built query language, handling high log volume without needing additional infrastructure. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of native AWS monitoring services versus over-engineered streaming or storage solutions—a common trap is choosing Kinesis Data Firehose or S3 for analysis, but those services lack built-in querying capabilities. Remember the memory tip: “Agent sends, Insights mends”—the CloudWatch agent sends logs to CloudWatch, and Insights mends the analysis gap by letting you search and visualize directly.
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 company is designing a new application that will run on Amazon EC2 instances. The application writes logs to local disk, and the logs must be aggregated centrally for analysis. The company wants a solution that requires minimal configuration and can handle high log volume. Which TWO AWS services should the company use?
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 collect logs from EC2 instances via the CloudWatch agent. Option C is correct because CloudWatch Logs Insights allows querying and analyzing logs. Option B is wrong because S3 is for log storage, not analysis. Option D is wrong because Kinesis Data Firehose is for streaming data, not for EC2 log collection. Option E is wrong because Lambda is not used for log analysis.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Amazon S3
Why it's wrong here
S3 can store logs but does not provide built-in analysis tools.
✗
AWS Lambda
Why it's wrong here
Lambda can process logs but requires custom code; CloudWatch Logs Insights is simpler.
✗
Amazon Kinesis Data Firehose
Why it's wrong here
Firehose is for streaming data to destinations, not for direct EC2 log collection.
✓
Amazon CloudWatch Logs
Why this is correct
CloudWatch Logs can collect logs from EC2 instances using the CloudWatch agent.

Common exam traps
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.
Detailed technical explanation
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.
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.
