• D. It includes snapshot functionality
• E. It can be used to mirror the root filesystem

Which three statements are correct about NFSV4?

• A. It relies on the LOCKD and RPC.STATD daemons to perform file locking.
• B. It uses a single port (2049) for all client/server communications.
• C. RPC.IDMAPD is used to map a UID to its username and a GID to its group name and vice versa.

Examine the files and directories shown:


What is the reason for this configuration? (Choose the best answer.)

• A. The links in /etc to the directories in /etc/rc.d are provided to allow /etc/rc.d/rc to work properly
• B. The links in /etc to the directories in /etc/rc.d are not required and must have been added by the administrator
• C. The links in /etc to the directories in /etc/rc.d are provided to permit one set to have different owners or ppermissions than the other
• D. The links in /etc to the directories in /etc/rc.d are provided to make Linux run level processing configuration resemble the SysV UNIX configuration

Examine these statements and their output taken right after successful install of Oracle Linux:
[root@FAROUT /] rpm -q firstboot
Firstboot -1.110.10-1.0.2.e16.x86_64
[root @FAROUT /] # chkconfig - - list firstboot
Firstboot 0:off 2:off 3:off 4:off 5:off 6;off
[root@FAROUT /] # /etc/sysconfig/firstboot
RUN_FIRSTBOOT=NO
What is the conclusion?

• A. The system was installed without selecting desktop graphical packages, thereby disabling firstboot from running.
• B. The option to run firstboot was deselected during Oracle Linux installation.
• C. Firstboot never ran in any run level because the service is turned off for all run levels.
• D. The system was installed with desktop graphical packages and rebooted and the firstboot utility ran successful.

Examine this output captured on an NFS server:
# mount | grep export
/dev/sdc1 on /export type ext3 (rw)
/dev/sdc2 on /export/share2 type ext3 (rw)
# cat /etc/exports
/export (*ro)
You mounted the /export filesystem on an NFS client using the command:
# mount NFS_SERVER:/export/mnt
What is the result of listing the files in /mnt/share2 on the NFS client?

• A. It results in a permission denied error.
• B. It lists any files stored in the root directory in the /dev/sdc2 partition of the NFS server.
• C. It produces no output.
• D. It lists any files stored in the share2 directory in the /dev/sdc1 partition of the NFS server.
• E. It results in a stale NFS handle error.
