You have an unmounted btrfs file system: # btrfs filesystem show Label: 'Btrfs' uuid: 7bfe3239-47ee-442b-b9f8-49f88b6b1be4 Total devices 3 FS bytes used 300.51MB devid2 size 4.88GB used 1.06GB path /dev/sdd devid1 size 4.88GB used 580.00GB path /dev/sdc devid3 size 4.88GB used 1.50GB path /dev/sdb You have these mounted devices: # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_exam1-LogVol_system

You have a mount point for the btrfs file system:
# ls -all /btrfs

drwxr-xr-x. 1 root root 0 Aug 12 10:17 .
dr-xr-xr-x. 1 root root 276 Aug 12 10:36 ..
Examine these steps:
1.Manual defragment is not needed. Btrfs will defragment it automatically.
2.btrfs device defragment /dev/sdd
3.btrfs filesystem defragment /btrfs
4.btrfs device delete /dev/sdb /btrfs
5.mount UUID=7bfe3239-47ee-442b-b9f8-49f88b6b1be4 /btrfs
6.btrfs device delete /dev/sdb /dev/sdd
What is the correct order to delete the /dev/sdb device from the btrfs file system and for defragmenting the reduced file system?

Examine the UserDir directives in this extract from /etc/httpd/conf/httpd.conf:
<Ifmodule mod_userdir.c>
UserDir enabled user1
UserDir disabled user1
UserDir public_html
</ifModule>
The web server URL is http://host01.
A website exists in the user's directory /home/user1/public_html.
A user attempts to access user1's webpages by using the URL:
http://host01/~user1
Which statement describes the outcome?

• A.The occurrence ofuser1in the list of enabled users allows access to the website contained inuser1'spublic_htmlsubdirectory, overridding thedisableddirective.
• B.Access is granted because theUserDir public_htmldirective applies default access to all local users on the system, overriding theenabledordisableddirective.
• C.The configuration produces an error upon web server startup, because theenabledanddisableddirectives conflict.
• D.The occurrence ofuser1in the list of disabled users causes anaccess deniederror to the website contained inuser1'spublic_htmlsubdirectory, overridding theenableddirective.

What statement describes the iSCSI client system's iSCSI database?

• A.The client maintains a local database in the form of a directory tree structure in/etc/iscsi/db.
• B.The client maintains a text formatted file,/etc/iscsi/iscsi.db.
• C.The client maintains a local database in the form of a directory tree structure in/var/lib/iscsi.
• D.The client can use either a local database in the form of a Berkeley DB formatted file in/etc/iscsior a distributed database in the form of Internet StorageNaming Service (iSNS) as its database. It is a decision for the System and StorageAdministration team.
