Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Send all logs to a single S3 bucket without partitioning
Why it's wrong here
Unorganized logs hinder queryability; partitioning by date/service helps.
- ✓
Include timestamp, severity, and request ID in each log entry
Why this is correct
These fields enable filtering and correlation.
- ✓
Use a consistent schema across all services
Why this is correct
Consistency allows unified querying across logs.
- ✓
Write logs in JSON format
Why this is correct
JSON is a common structured format that is easy to parse and query.
- ✗
Encrypt log files at rest using AWS KMS
Why it's wrong here
Encryption is a security practice, not a structure for querying.
