- A
Stream logs to Amazon Elasticsearch Service and use Kibana alerts
Why wrong: Elasticsearch ingestion introduces latency.
- B
Use S3 event notifications to trigger Lambda functions on new log files
Why wrong: S3 events are not real-time due to log aggregation delays.
- C
Export logs to S3 and use Amazon Athena queries with scheduled rules
Why wrong: Athena is for batch, not real-time.
- D
Use Amazon Kinesis Data Analytics for real-time analysis and AWS Lambda for automated response
Kinesis Data Analytics can process streaming data and trigger Lambda for immediate action.

SCS-C02 Threat Detection and Incident Response Practice Question
This SCS-C02 practice question tests your understanding of threat detection and incident response. 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 company has a requirement to detect and respond to threats in near real-time by analyzing VPC Flow Logs. The logs are generated in a VPC and sent to CloudWatch Logs. What is the MOST efficient way to analyze these logs for suspicious patterns and trigger automated responses?
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
✓
Use Amazon Kinesis Data Analytics for real-time analysis and AWS Lambda for automated response
Amazon Kinesis Data Analytics can process streaming VPC Flow Logs from CloudWatch Logs in near real-time using SQL or Apache Flink, enabling immediate detection of suspicious patterns. AWS Lambda can then be triggered to automate incident response actions, such as updating security groups or isolating instances, making this the most efficient solution for near real-time threat detection and response.
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

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose batch-oriented solutions like Athena or S3 event notifications, overlooking the explicit 'near real-time' requirement in the question, which demands a streaming analytics approach.
Detailed technical explanation
How to think about this question
Kinesis Data Analytics uses a runtime environment that continuously reads from a Kinesis Data Streams or Kinesis Data Firehose source; in this scenario, a subscription filter in CloudWatch Logs can stream logs directly to Kinesis Data Firehose, which then feeds Kinesis Data Analytics. The analytics application can detect patterns like port scans or unusual traffic volumes using sliding windows, and output results to a Lambda function via a destination stream for immediate remediation. A real-world scenario is detecting a DDoS attack within seconds and automatically updating a network ACL to block the source IP.
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.
