Which directory is the primary location for log files in a Linux system?

• A. /var/log
• B. /var
• C. /tmp
• D. /home

Answer: (D)

Logs are stored in a place designed for data that grows over time, specifically under /var/log. This directory houses system and application logs such as syslog, messages, auth.log, and service-specific logs, and many systems also store binary journal data there (viewable with journalctl). The reason is that /var is meant for variable data produced by the system and services, while /tmp is for ephemeral files that may be cleared on reboot, and /home holds user home directories. So the primary location for log files is /var/log.
