Linux Foundation Certified System Administrator (LFCS) — Question 132

In case neither cron.allow nor cron.deny exist in /etc/, which of the following is true?

Answer options

• A. Without additional configuration, no users may have user specific crontabs.
• B. Without additional configuration, all users may have user specific crontabs.
• C. The cron daemon will refuse to start and report missing files in the system's logfile.
• D. When a user creates a user specific crontab the system administrator must approve it explicitly.

Correct answer: A

Explanation

The correct answer, A, is accurate because the absence of both cron.allow and cron.deny means that no users are granted permission to create user-specific crontabs by default. Options B, C, and D are incorrect because they misrepresent the behavior of the cron system in the absence of these files.
