D) It limits incident response actions
Explanation: Enrichment adds contextual details to raw events, making it easier to identify true threats
and prioritize responses.
Question 14: Which of the following is a best practice for log collection in SIEM?
A) Collect logs only from a single source
B) Aggregate logs from multiple sources consistently
C) Ignore timestamps in logs
D) Only collect logs during an incident
Explanation: Aggregating logs from multiple sources ensures a comprehensive view of the security
landscape, enabling effective analysis.
Question 15: What is the main challenge addressed by log parsing techniques?
A) Converting logs into a human language
B) Standardizing various log formats for unified analysis
C) Compressing log files for storage
D) Encrypting log data for security
