Frequently Asked Questions (Server & OS Administration)
Why is SSH passwordless key authentication safer than passwords?
Cryptographic SSH keys resist brute-force dictionary attacks, cannot be easily guessed, and can be further protected with passphrase passkeys.
What is the function of systemd in modern Linux distributions?
Systemd is an init system and service manager that bootstraps the user space, manages background daemons, and logs system events via journalctl.
How do you automate server maintenance tasks?
Linux uses cron jobs (/etc/cron.d), while Windows Server uses Task Scheduler to trigger automated PowerShell or Bash scripts on recurring schedules.
