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

Which statement is true?

A. The syntax is invalid and causes the parser to fail when the target service is started. No LUN assignments are made and no disks are visible to the clients.

B. The syntax is invalid but defaults apply. If you assign any LUN addresses manually, then you must assign all for that target. Therefore, default assignments apply. physDisk1.img = 1, phyDisk2.img = 2. phyDisk3.img = 3

C. phyDisk1.omg is assigned the next available LUN number above the existing allocated numbers. LUN = 4

D. phyDisk1.img is assigned the lowes available LUN number that is not assigned. LUN = 2

Examine the command sequence and the output produced:

Which statement is true?

A. The tgtadm commands succeed and effect both the configuration in /etc/tgt/targets.conf and the running configuration.

B. Both tgtadm commands succeed. No changes are made to the configuration file.

C. Only one tgtadm command succeed. The deletion of target 1 fails because LUN 0 has not been deleted.

D. Both tgtadm commands succeed. The tgtadm commands issued affects the ctatic configuration only and do not affect currently accessed target/LUN combinations.
