• Question 169:

  Examine the code fragment from /etc/tgt/targets.conf:

  backing-store /iSCSIsharedDisk/physDisk1.img

  write-cache off

  backing-store / iSCSIsharedDisk/physDisk2.img

  initiator-address 192.0.2.105

  initiator address 192.0.2.106

  write-cache off

  backing-store /iSCSIsharedDisk/physDisk3.img

  write-cache off

  Which statement is true?

  A. Only the target identified by the iqn ending with mypc:2 is visible. This target is visible to the specific clients identified by the initiator address.

  B. The initiator-address syntax in not valid. The address value should be specified as an iqn, not an IP address. This causes an error, and only iqns ending with mypc:1 and mypc:3 are visible.

  C. All targets are visible to prospective clients, but the target iqn ending with mypc:2 is visible exclusively to the specified IP addresses.
