Question 770
Original unofficial RHEL 10 RHCSA skill-check scenario: A developer can read an ext4 file but cannot change it despite being the file owner because the filesystem is mounted read-only. Which observation best confirms the intended outcome?
Explanation
Correct Answer
In this RHEL 10 system administration case: A developer can read an ext4 file but cannot change it despite being the file owner because the filesystem is mounted read-only. Underlying reason: Mount flags can override otherwise sufficient file permissions. The most direct, approved resolution is: Inspect mount state and fix the approved filesystem-level condition rather than using chmod. Confirm it by checking: The filesystem is writable after safe remediation and file mode remains appropriate. Sustain the fix by: Check mount options before changing ownership. This is the INTENDED response for the strongest objective verification result. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;
Incorrect Answers
Authorized users traverse the path and open the intended file. That is not sufficient for the reported RHEL task, because mount flags can override otherwise sufficient file permissions.
`df -h` reports the intended larger filesystem and original files remain. That is not sufficient for the reported RHEL task, because mount flags can override otherwise sufficient file permissions.
Mount succeeds when the server export is available and authorized. That is not sufficient for the reported RHEL task, because mount flags can override otherwise sufficient file permissions.
