What technique can be used to protect the integrity of log entries from tampering?

Digitally signing log entries or using a tamper-evident log

A team is migrating their application logs from plain text to structured JSON. They want to make the logs easier to query in their central log management system. Which additional benefit does structured logging provide beyond plain text?

It eliminates the need for a central log aggregation system because logs are self-describing.

It allows the log management system to index individual fields, enabling precise queries like filtering by 'user_id' or 'status_code'.

It automatically reduces the storage size of logs by compressing the JSON format.

It guarantees that no sensitive data will be logged because JSON is a secure format.

How can logs be used to monitor application health?

By analyzing log patterns to detect errors, slow responses, or unusual activity

By manually reading all logs periodically

By counting the number of log lines generated per second

By checking the file size of the log files

When should the DEBUG log level be used in a production application?

For all log messages to ensure no information is missed

For detailed diagnostic information that is typically only needed when troubleshooting a specific issue

For recording user authentication events

For logging errors that occur during application startup
