RedHat EX200 Exam Practice Questions (P. 1)

GPT-4o - Answer

To set up the directory "/home/admins" correctly for the admin group, with users having read and write permissions while excluding others, the commands should create the directory, associate it with the 'admin' group, and properly set permissions and the setgid bit. This ensures files created within remain associated with the group. Commands to achieve this are: `mkdir /home/admins`, `chgrp admin /home/admins`, `chmod 770 /home/admins`, and `chmod g+s /home/admins`. This setup allows group members to read and write, but prevents access from non-group members and maintains group ownership for new files.

GPT-4o - Answer

The best way to set up a cron job like this is through the crontab editor. Use the command `crontab -e`, which opens the current user's crontab file in the default text editor. Add the line `23 14 * * * echo "hello"` to run your task at 14:23 every day. Always ensure to check the cron job configuration afterward by using `crontab -l`. This approach suits both general users and those studying the ex200 exam, focusing on practical application and verification of task setup.

GPT-4o - Answer

To correctly copy files owned by 'harry' to /opt/dir/, ensure the directory exists first. The command is: `find / -user harry -type f -exec cp {} /opt/dir/ \;`. This command finds files systemwide owned by 'harry', then copies them to the specified directory. It’s efficient and sticks directly to requirements. Always replace 'Harry' with 'harry' since Linux usernames are case-sensitive, and verify directory permissions might allow the copy operation to proceed without errors.
