Examine the contents of the dhcp configuration file:
# cat /etc/dhcp/dhcpd.conf
subnet 192.168.100.0 netmask 255.255.255.0 {
range 192.168.100.100 192.168.100.200;
}
host host100 {
hardware ethernet 00:0c:29:B9:07:41;
fixed-address 192.168.100.100;
}
Which statement is true about this DHCPD configuration?

• A. A lease request fromhost100fails only if address192.168.100.100is currently in use.
• B. A lease request fromhost100always fails.
• C. An attempt to startDHCPDfails due to the conflicting lease declaration for address192.168.100.100.
• D. A lease request fromhost100succeeds if the host assigned to address192.168.100.100is currently offline.
• E. A lease request fromhost100fails only if a previous lease on address192.168.100.100has expired.

Examine these commands and their output:
# mount | grep xfs
/dev/mapper/vg_xfs_xfs1 on /xfs1 typr xfs (rw, quota_
# xfs_quota -x -c 'enable -u' /xfs1
# xfs_quota -x -c 'enable -g' /xfs1
XFS_QUOTAON: Invalid argument
Identify the reason for the "Invalid argument" error.

• A. Group quotas are already enabled.
• B. The/xfs1file system is mounted without theuquotaandgquotaoptions.
• C. User and group quotas cannot be enabled at the same time.
• D. Project and group quotas cannot be enabled at the same time.
• E. The/xfs1file system is mounted without thegquotaoption.

A system has several multipathed devices. Some of them are in use with mounted file systems.
The remaining multipathed devices are unused.
The multipath command with the -F option is issued as shown:
[root@host03 /]# multipath -F
Which statement is true?

• A. All multipath mapping are flushed, thus removing theirmpathmappings. The mounted file system is unusable.
• B. All multipath mapping except those that are in use are flushed, removing their mappings. The mounted file system is unaffected.
• C. The command returns a syntax error because an mpath device name must be supplied as the argument to the-Fswitch.
• D. Any faulted multipath devices are fixed, causing their faulty paths to be rediscovered if the underlying device is found to be available again. The mounted file system is unaffected.

Which single statement is true for creating a labeled filesystem in RAID-1 on devices /dev/sdc and /dev/sdd?

• A. mkfs.btrfs -d raid1 -L Btrfs /dev/sdc /dev/sdd
• B. mkfs -t btrfs -d raid1 /dev/sdc /dev/sdd
• C. mkfs.btrfs -L Btrfs /dev/sdc /dev/sdd
• D. mkfs.btrfs -r raid1 -L Btrfs /dev/sdc /dev/sdd
