  B. HEA logical ports can only be used as a backup adapter when the physical ports are configured as primary adapters in an EtherChannel.
  C. When using HEA logical ports as primary adapters in an EtherChannel, the underlying physical ports must be in an EtherChannel at the switch level.
  D. The 'Internet Address to Ping' attribute must be enabled for logical HEA ports when the EtherChannel only includes primary adapters running at full duplex.

  A. resysnclvodm vjfslog1
  B. logform/dev/jfsiog1
  C. synclvodm appvg jfslog1

• Question 23:

  An existing LPAR hangs with an LED code of 0553 after a scheduled reboot. An administrator boots the LPAR into a maintenance mode to investigate the cause of the issue.

  All filesystems fsck cleanly. There is plenty of space in / and /tmp. And /etc/inittab appears to be intact and valid.

  Based on the following output, why is one of these symbolic links likely to be the cause of the LED code?

  

  A. /bin should be linked to/sbin
  B. /unix is attempting to boot a 32-bit kernel
  C. /bin/bsh should be pointing to /opt/freeware/bin/bash
  D. bash can interpret the AIX startup scripts differently to the default shell
  D. bash can interpret the AIX startup scripts differently to the default shell

• Question 24:

  What is a requirement for Live Partition Mobility?

  C. The client partition must be connected to a SAN.
  D. The client partition must be set up as a 'Mover Service Partition'.
  A. The network and disk must be virtual.

• Question 25:

  An administrator would like to update a VIO Server (VIOS) to the latest maintenance level. Which command, run from the restricted shell, will update the operating system on VIOS?

  A. vios_update
  B. update_all
  C. install-all
  D. updateios
  D. updateios

• Question 26:

  The following verification routine is part of a script used to automate cloning rootvg. This routine determines which disks are available for use. Applying the logic, what configuration of disk would be selected by the script as a candidate?

  

  A. A SAN disk virtualized by NPIV.
  B. A local physical SAS drive, currently a member of the vg00 volume group.
  C. A physical SATA disk drive, currently containing the altinst_rootvg volume group.
  D. A SAN disk virtualized as a Virtual SCSI disk, currently not part of a volume group
  D. A SAN disk virtualized as a Virtual SCSI disk, currently not part of a volume group

• Question 27:

  An existing LPAR is configured with a vSCSI disk for a root volume group. An administrator is configuring NPIV to provide secondary storage to the partition.

  DLPAR operations are used to add the required client and server adapters to the client and VIO Server partitions. Once the NPIV adapters have been configured, what action should be taken against the client LPAR to ensure access to SAN storage is not compromised?

  A. Shutdown and reboot AIX.
  B. Shutdown and reactivate the profile.
  C. Save the current configuration to a profile.
  D. Add the physical WWVPN to the virtual device configuration.
  C. Save the current configuration to a profile.

• Question 28:

  A new security policy dictates that unnecessary default user accounts be removed. Which default user IDs are most eligible for removal?

  A. nobody and adm
  B. root, sys and system
  C. daemon, Ipd, adm and guest

  C. A supported disk in a highly available storage configuration that is accessible by all nodes that form the cluster
  D. A "quorum busting" disk to prevent loss of quorum from impacting availability of the cluster configuration data.
  C. A supported disk in a highly available storage configuration that is accessible by all nodes that form the cluster

• Question 30:
