IBM C4040-221 Online Questions & Answers

• Question 91:

  An existing client LPAR has been manually moved from one physical machine to another. The administrator updated the SAN zoning to deallocate from the source VIO Server and allocate to the destination VIO Server. The LPAR and its profile were recreated on the HMC and the single disk is mapped from the VIO Server to the LPAR.

  What manual intervention is required after activating the LPAR?

  A. Select a boot device.
  B. Correct the system clock.
  C. Correct the terminal type.
  D. Import non-root volume groups
  A. Select a boot device.

• Question 92:

  A company has numerous LPARs hosting database servers, and three versions of the DBMS deployed in the environment. A critical APAR fixes data corruption for one version of the database, but it requires a server reboot. The only inventory information available is a spreadsheet with every LPAR's hostname and root password.

  Which sequence of tasks will determine which servers are missing the critical APAR, and only apply it to the servers running the affected level of the database?

  A. Use the spreadsheet to populate the /etc/hosts file on the management node. Configure a NIM server that has the APAR in an lpp_source. Force-register all of the LPARs with the NIM server. Use NIM group operations to install the APAR and boot at a scheduled time.
  B. Use the spreadsheet to create a dsh node list. Use dsh with Islpp to create a node list for LPARs needing the APAR. Use dcp and dsh to install the APAR and reboot.
  C. Configure a Systems Director server using the spreadsheet import function. Use the inventory function to discover the database level and APAR status. Use the Update Manager to apply the APAR to the affected LPARs and reboot.
  D. Use the spreadsheet to create a dsh node list. Use dcp and dsh to install the APAR. Use dsh to reboot the systems.
  B. Use the spreadsheet to create a dsh node list. Use dsh with Islpp to create a node list for LPARs needing the APAR. Use dcp and dsh to install the APAR and reboot.

• Question 93:

  A mirrored rootvg internal disk, hdisk1, has failed and must be replaced. The remaining mirrored disk, hdisk0, is intact and functioning normally.

  What is the correct sequence of actions?

  A. unmirrorvg rootvg hdisk1 reducevg roolvg hdisk1 rmdev -I hdisk1 -d physically replace hdisk1 cfgmgr extendvg rootvg hdisk1 mirroivg rootvg Run a bosboot on both disks
  B. rmdev-l hdisk1 -d physically replace hdisk1 cfgmgr unmirrorvg rootvg hdisk1 reducevg rootvg hdisk1 extendvg rootvg hdisk1 mirrorvg rootvg Run a bosboot on both disks
  C. unmirrorvg rootvg hdisk1 rmdev-I hdisk1 -d physically replace hdisk1 reducevg rootvg hdisk1 cfgmgr extendvg rootvg hdisk1 mirrorvg rootvg Run a bosboot on both disks
  D. unmirroivg rootvg hdisk1 reducevg rootvg hdisk1 rmdev -I hdisk1 -d physically replace hdisk1 cfgmgr extendvg rootvg hdisk1 Run a bosboot on both disks mirrorvg rootvg
  A. unmirrorvg rootvg hdisk1 reducevg roolvg hdisk1 rmdev -I hdisk1 -d physically replace hdisk1 cfgmgr extendvg rootvg hdisk1 mirroivg rootvg Run a bosboot on both disks

• Question 94:

  Automated scripts on an AIX system require secure non-root access to another AIX instance. Secure Shell (SSH) was the method chosen and installed on both systems. How can an administrator use SSH to create secure automated jobs without storing passwords in the automated scripts?

  A. issue ssh-keygen -t dsa on the source as non-root user append source id_dsa.pub contents to target /etc/ssh/sshd_config file restart sshd daemon
  B. issue ssh-keygen -t dsa on the source as root append source id_dsa.pub contents to /etc/ssh/ssh_config file on the target restart sshd daemon
  C. issue ssh-keygen -t dsa on the source as non-root user append source id_dsa.pub contents to the authorized_keys file on the target restart sshd daemon
  D. issue ssh-keygen -t dsa on the source as non-root user append source id_dsa.pub contents to the authorized_keys file on the target
  D. issue ssh-keygen -t dsa on the source as non-root user append source id_dsa.pub contents to the authorized_keys file on the target

• Question 95:

  Performance monitoring is needed for a managed system containing multiple AIX7 LPARs. Which action enables historical data capture for the managed system?

  A. Implement IBM Systems Director Standard Edition.
  B. Run snap data collections periodically.
  C. Configure the trace facility to capture details on system activity.
  D. Configure NMON to collect interval-based performance data.
  D. Configure NMON to collect interval-based performance data.

• Question 96:

  What is the difference between deferred and concurrent firmware updates?

  A. Deferred firmware can be applied concurrently but contains updates that affect the internal program load path, which are not activated until the next time the server is shut down and restarted.
  B. Concurrent firmware must be done on all LPARs in the frame at the same time. Deferred firmware can be loaded on each LPAR at a different time and only becomes active when the LPAR is shutdown and restarted.
  C. Deferred firmware can only be applied during an outage to the managed system as it will automatically shut the managed system down during its installation.
  D. Concurrent firmware is only for minor fixes to the system mircocode while deferred firmware contains major fixes to the service processor.
  A. Deferred firmware can be applied concurrently but contains updates that affect the internal program load path, which are not activated until the next time the server is shut down and restarted.

• Question 97:

  Which option explains why a user-created local filesystem does not automatically mount when the system boots?

  A. No port is specified for mountd in/etc/services.
  B. The filesystem does not belong to a mount group.
  C. The mount filesystem attribute is missing in /etc/filesystems.
  D. The portmap daemon is not configured to start in /etc/inetd.conf.
  C. The mount filesystem attribute is missing in /etc/filesystems.

• Question 98:
