質問 8：
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. 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.
B. Only the target identified by theiqnending withmypc:2is visible. This target is visible to the specific clients identified by the initiator address.
C. 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.
D. All targets are visible to prospective clients, but the targetiqnending withmypc:2is visible exclusively to the specified IP addresses.
正解：C
