Question 720
Original unofficial RHEL 10 RHCSA skill-check scenario: A data-center share is unreachable while the server is offline and a user assumes a local chmod change will restore it. Which ongoing practice best prevents a recurrence?
Explanation
Correct Answer
In this RHEL 10 system administration case: A data-center share is unreachable while the server is offline and a user assumes a local chmod change will restore it. Underlying reason: NFS depends on network service and remote export policy. The most direct, approved resolution is: Confirm server/network reachability and export status before local permission changes. Confirm it by checking: Mount succeeds when the server export is available and authorized. Sustain the fix by: Monitor server availability and client mount failures. This is the INTENDED response for the best ongoing operational safeguard. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;
Incorrect Answers
Standardize identity expectations across NFS clients. That is not sufficient for the reported RHEL task, because NFS depends on network service and remote export policy.
Include parent-directory checks in permission troubleshooting. That is not sufficient for the reported RHEL task, because NFS depends on network service and remote export policy.
Check `findmnt -o OPTIONS` during access troubleshooting. That is not sufficient for the reported RHEL task, because NFS depends on network service and remote export policy.
