IBM C4040-109 Online Questions & Answers

• Question 41:

  While reactivating client LPARs following a scheduled power down, some LPARs have lost visibility to their NPIV-allocated SAN LUNs. On investigation it appears the WWNs have changed on the problem LPARs. What is the most likely cause for the change in WWN?

  A. The option to randomly assign WWNs for security reasons has been selected.
  B. The NPIV adapters on the VIOS LPARs were not tagged as being "required for partition activation."
  C. The virtual Fibre Channel client adapters were dynamically allocated to the LPARs before being added to the partition profile.
  D. The WWNs will have changed due to the recycle of the Hypervisor. The chsyscfg -r command should be used to recover the previously allocated WWN.
  C. The virtual Fibre Channel client adapters were dynamically allocated to the LPARs before being added to the partition profile.

• Question 43:

  An administrator receives the following error while performing a backup of a VIO Server.

  

  What can the administrator do to backup the VIO Server successfully?

  B. Increase the size of the /home/padmin/backup filesystem.
  C. Change the ownership of the /home/padmin/backup directory to padmin.
  D. Run the backupios command again using the -mksysb flag
  D. Run the backupios command again using the -mksysb flag

• Question 44:

  An administrator is interested in installing PowerVM Lx86 software on a new Power 770 for a proof of concept. Which of the following statements about PowerVM Lx86 is true?

  A. PowerVM Lx86 can be implemented on VIO server 2.1 FP21 and higher.
  B. PowerVM Lx86 supports only 64 bit applications that run in x86 real mode.
  C. PowerVM Lx86 allows for many x86 Linux applications to run on supported versions of Linux on Power.
  D. PowerVM Lx86 allows for x86 Linux applications to run under AIX 6.1 or 7.1 Enterprise Edition.
  C. PowerVM Lx86 allows for many x86 Linux applications to run on supported versions of Linux on Power.

• Question 45:

  An administrator has dynamically allocated a new virtual FC adapter to an AIX client. When running cfgrngr on the client, the administrator receives the following error:

  Method error (/usr/lib/methods/cfg_vfc -I fcs0):

  0514-040 Error initializing a device into the kernel

  Which of the following could explain the error?

  A. The client adapter has been configured to use a 32bit kernel.
  B. The fileset devices.vdevice.vfc-client.rte needs to be installed.
  C. The physical fibre channel adapter on the VIO server does not support NPIV.
  D. The client adapter has been configured to use an invalid virtual server adapter
  D. The client adapter has been configured to use an invalid virtual server adapter

• Question 46:

  An administrator is trying to perform Live Partition Mobility (LPM) between physical systems managed by the same HMC. The VIO Servers (VIOS) on each physical system are connected to the same SAN. The client LPARs will use virtual SCSI (vSCSI) disks. The SCSI adapter slot numbers are between 11 and 20.Each client LPAR has a unique name. The network used by the client LPARs use Logical Host Ethernet adapters (LHEA).The PowerVM Enterprise edition is being used. No EtherChannel has been configured. Why are LPM activities failing?

  A. This LHEA configuration is not supported for LPM.
  B. The SCSI adapter slot numbers are too high.
  C. Multiple MSP (mover service partitions) were configured.
  D. The ssh keys have not been exchanged between the two VIO servers.
  A. This LHEA configuration is not supported for LPM.

• Question 47:

  A new NPIV VIO client is being built. How can the administrator log all virtual Fibre Channel adapters into the SAN so the WWPNs are visible for disk mapping?

  A. Boot the LPAR to SMS and run the configure boot device.
  B. Boot the LPAR normally, use the lsmap -all -npiv command on the VIO server to check it has logged in.
  C. Boot the LPAR into the Open Firmware prompt and run ioinfo command.
  D. Boot the LPAR from a NIM server and access a maintenance shell.
  D. Boot the LPAR from a NIM server and access a maintenance shell.

• Question 48:

  A P0WER7 system has been recently installed and 4 uncapped shared processor LPARs have been defined.

  

  The use of Multiple Shared Processor Pools has been decided upon for licensing and performance reasons.

  

  When adding PROD1 to the Production pool via the command line, the following error is given

  "This operation is not allowed because the partition is using dedicated processors"

  A. P0WER6 mode is enabled
  B. LPAR has not been powered on
  C. LPAR has been powered on
  D. The Pool has insufficient processor units
  B. LPAR has not been powered on

• Question 49:

  An AIX LPAR has a disk drive known as hdisk17. The administrator would like to change the name of the disk to redolog0. Which command will achieve this?

  A. rendev -l hdisk17 -n redolog0
  B. mv /dev/hdisk17 /dev/redolog0
  C. chdsk -dev hdisk17 -id redolog0
  D. chdev -l hdisk17 -a name=redolog0
  A. rendev -l hdisk17 -n redolog0

• Question 50:

  An administrator would like to use system plans to clone the partition definitions of an existing Power 795 system to a new Power 795. Both systems have the same hardware configuration.

  When the administrator attempts to deploy the system plan taken from the old system to the new one the 'Deploy System Plan' wizard fails at the hardware validation stage.

  Which of the following actions would allow the administrator to deploy the system plan from the old

  A. Select the 'Ignore Hardware Validation' option when deploying the System Plan.
  B. Use the System Plan Conversion Wizard from the System Plans menu on the HMC.
  C. Export the original sysplan with the 'Allow Deployment On Remote System1 option.
  D. Use the System Planning Tool (SPT) to validate and convert the original system plan for deployment.
  D. Use the System Planning Tool (SPT) to validate and convert the original system plan for deployment.
