Question 2

Examine the code fragment from /etc/tgt/targets.conf:
<target iqn.2013-03.com.example.mypc:1>
backing-store /iSCSIsharedDisk/physDisk1.img
write-cache off
</target>
<target iqn.2013-03.com.example.myps:2>
backing-store / iSCSIsharedDisk/physDisk2.img
initiator-address 192.0.2.105
initiator address 192.0.2.106
write-cache off
</target>
<target iqn.2013-03.com.example.mypc:3>
backing-store /iSCSIsharedDisk/physDisk3.img
write-cache off
</target>
Which statement is true?

A. Only the target identified by theiqnending withmypc:2is visible. This target is visible to the specific clients identified by the initiator address.

B. Theinitiator-addresssyntax is not valid. The address value must be specified as aniqn, not an IP address. Theinitiator-addressparameters are ignored and all targets are visible withoutrestriction.

C. All targets are visible to prospective clients, but the targetiqnending withmypc:2is visible exclusively to the specified IP addresses.

D. Theinitiator-addresssyntax in not valid. The address value should be specified as aniqn, not an IP address. This causes an error, and onlyiqns ending withmypc:1andmypc:3are visible.

Correct Answer: D

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. The configuration produces an error upon web server startup, because theenabledanddisableddirectives conflict.

C. The occurrence ofuser1in the list of disabled users causes anaccess deniederror to the website contained inuser1'spublic_htmlsubdirectory, overridding theenableddirective.

D. Access is granted because theUserDir public_htmldirective applies default access to all local users on the system, overriding theenabledordisableddirective.

Correct Answer: A
