Refer to the exhibit. What does the output indicate about the user John Doe's access to the file report.txt?
⚠ Common exam trap
LPI often tests the distinction between lock type and deny mode, where candidates confuse a read lock with no deny mode for an exclusive lock or assume any lock prevents all access, but the deny mode specifically controls what other clients can do.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user has a read lock with no deny mode.
The output shows that John Doe has a read lock on report.txt with no deny mode, meaning other processes can still read the file while he holds the lock. This is indicated by the lock type 'R' (read) and the absence of a deny mode (deny mode 'NONE'). In Samba, a read lock with no deny mode allows concurrent read access but prevents write access from other clients.
