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?

  1. 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.
  2. 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.
  3. All targets are visible to prospective clients, but the target iqn ending with mypc:2 is visible exclusively to the specified IP addresses.
  4. The initiator-address syntax is not valid. The address value must be specified as an iqn, not an IP address. The initiator-address parameters are ignored and all targets are visible without restriction.

Answer(s): B

Examine the parameters shown using the sysctl command relating to panic situations:
[root@WAYOUT etc]# sysctl –a |grep panic |grep –v hung
kernel.panic = 0
kernel.panic_on_oops = 0
kernel.softlockup_panic = 0
kernel.unknown_nmi_panic = 0
kernel.panic_on_unrecovered_nmi = 0
kernel.panic_on_io_nmi = 0
kernel.panic_on_oom = 2
[root@WAYOUT etc]# sysctl –a |grep hung

kernel.hung_task_panic = 0
kernel.hung_task_chek_count – 4194304
kernel.hung_task_timeout_secs = 120
kernel.hung_task_warnings = 10

Which two statements are true about system behavior?

  1. The kernel delays panic for a few seconds if a bug is encountered to allow the klogd kernel logging daemon to log the oops output.
  2. The kernel panics if a kernel thread sleeps in the TASK_UNINTERRUPTABLE state for more than 120 seconds.
  3. The kernel attempts to continue if a bug is encountered.
  4. The kernel always panics if an out-of-memory condition arises.
  5. The kernel tries to kill some memory-consuming processes to avoid a panic if an out-of- memory condition arises.
  6. The kernel panics if a user thread sleeps in the TASK_UNINTERRUPTABLE state for more than 120 seconds.

Answer(s): B,F
