LPIC-2 File Sharing and Samba Practice Question
A Samba administrator needs to configure a share that allows only the user 'alice' and the group 'developers' to read and write files. Others should have no access. Which two parameters should be set in the share definition? (Choose two.)
⚠ Common exam trap
A common mix-up: candidates confuse 'valid users' with 'write list' or think 'invalid users' can be used to deny everyone except the listed users, but 'invalid users' explicitly blocks those users rather than allowing them, and 'write list' alone does not restrict access to only those users.
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
✓
valid users = alice, @developers
The 'valid users' parameter restricts access to only the specified users and groups, so setting 'valid users = alice, @developers' ensures only alice and members of the developers group can connect to the share. The 'write list' parameter grants write access to the listed users and groups, overriding any read-only setting; combining it with 'valid users' ensures that alice and the developers group have both read and write permissions, while all others are denied access entirely.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
valid users = alice, @developers
Why this is correct
Restricts access to alice and members of the developers group.
- ✗
invalid users = alice, @developers
Why it's wrong here
This would deny access to alice and developers.
- ✗
force user = alice
Why it's wrong here
This forces all connections to the share to run as alice, but does not restrict access.
- ✓
write list = alice, @developers
Why this is correct
Grants write access to alice and developers.
- ✗
read list = alice, @developers
Why it's wrong here
This would give them read-only access, not write.
