A few more sample questions
Sample question 1. Volume group vg_data has several physical volumes with enough free extents elsewhere. The administrator wants to retire /dev/vdb while the logical volumes stay online. Which command moves the allocated extents off /dev/vdb first?
- vgreduce vg_data /dev/vdb first, then pvmove
- pvremove /dev/vdb, then vgreduce vg_data /dev/vdb
- pvmove /dev/vdb, then vgreduce and pvremove
- lvreduce -L -10G /dev/vg_data/lv_app on every volume
Sample question 2. The directory /shared already gives the group qa rwx through an access ACL. Files and directories created in /shared from now on must also give qa read and write access, without changing their owners. Which command achieves this?
- setfacl -m d:g:qa:rwx /shared
- setfacl -m g:qa:rwx /shared
- setfacl -R -m g:qa:rwX /shared
- chmod g+s /shared
Sample question 3. Create the account svcbackup with UID 2001. It is used only to own files and run a service, so nobody may log in to it interactively. Which command creates it?

- useradd -g 2001 -s /sbin/nologin svcbackup
- useradd -u 2001 -M svcbackup
