LPIC-2 File Sharing and Samba Practice Question
Exhibit
Refer to the exhibit. [global] workgroup = MYGROUP server string = Samba Server security = user [share1] path = /srv/samba/share1 valid users = alice, bob read only = no [share2] path = /srv/samba/share2 valid users = @staff read only = yes [share3] path = /srv/samba/share3 guest ok = yes read only = no
Given the smb.conf exhibit, which share(s) allow write access to user 'alice' who is a member of the 'staff' group?
⚠ Common exam trap
Test-takers frequently assume that being a member of the 'staff' group grants write access to all shares, but they must check each share's specific 'write list' and 'valid users' directives, as share3 explicitly restricts access to bob only.

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
✓
share1 only
In the smb.conf exhibit, share1 has 'write list = @staff' which grants write access to all members of the staff group, including user alice. share2 has 'read only = yes' and no write list, so it is read-only for everyone. share3 has 'valid users = bob' and 'write list = bob', so only bob can write; alice is not listed and is not in the bob group, so she has no write access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
share1 and share3
Why it's wrong here
Although share1 allows write access to alice via @staff, share3 restricts write access to bob only, so alice cannot write to share3.
- ✗
share3 only
Why it's wrong here
Share3 specifies 'valid users = bob' and 'write list = bob', so only bob has write access; alice is not authorized.
- ✓
share1 only
Why this is correct
Share1 has 'write list = @staff', granting write access to all members of the staff group, including alice. share2 is read-only and share3 is restricted to bob.
- ✗
share2 only
Why it's wrong here
Share2 is set to 'read only = yes' with no write list, making it read-only for all users.
