IBM C4040-109 Online Questions & Answers

• Question 111:

  A Linux LPAR is configured using 802.1Q.

  The virtual Ethernet device is configured as an 802.1Q compatible adapter and has VLAN ID 5 configured in the 802.1Q additional VLAN field.

  The administrator runs the following commands on the Linux LPAR shell without errors:

  vconfig add eth0 5ifconfig eth0 10.0.0.2 netmask 255.255.255.0

  When the administrator tries to ping 10.0.0.1, the request times out.

  What is the problem?

  A. The VLAN ID should be in the VLAN-ID field in the virtual Network device configuration.
  B. The administrator is using the incorrect Ethernet device.
  C. The 8021q module is not loaded.
  D. The 802.1Q interfaces are not supported on Linux on Power Systems servers.
  A. The VLAN ID should be in the VLAN-ID field in the virtual Network device configuration.

• Question 112:

  An administrator has written a script to back up user-defined disk structures on a VIO server. The script makes a list of non-rootvg structures and then uses the savevgstruct command to backup the list of structures. While testing the script, the administrator finds that the disk structures are not all being successfully backed up. What is the most likely cause?

  A. The disk structure is currently offline. It needs to be online for the savevgstruct command to succeed.
  B. The disk structure is currently busy. It needs to be queisced to remove any file locks.
  C. The disk structure is a Virtual Media Repository. These are backed up using the backupios command.
  D. The disk structure is a Shared Storage Pool. These are backed up with the viosbk command.
  A. The disk structure is currently offline. It needs to be online for the savevgstruct command to succeed.

  vfchost0:U9119.FHA.44ABCDE-V2-C642:47:: :NOT_LOGGED_IN;fcs2:U5803.001.9112345-P2- C7-T1:0:4::

  vfchost1:U9119.FHA44ABCDE-V2-C643:48:lpar02AIX:LOGGED_IN:fcs2:U5803.001.9112345-P2- C7-T1:5:a:fcsO:U9119.FHA 44ABCDE-V48-C8-T1

  A. Virtual adapter vfchost1 is providing rootvg to the client LPAR.
  B. Virtual adapter vfchost0 tried an invalid path to the SAN.
  C. Virtual adapter vfchost1 is associated with adapterfcs0 on Ipar02.
  D. Virtual adapter vfchost0 is pointing to client LPAR id 47.
  C. Virtual adapter vfchost1 is associated with adapterfcs0 on Ipar02.

• Question 115:

  An administrator needs to update a legacy VIO server (VIOS) partition from version 1.5 to the most current version. The rootvg of the VIOS server is presented from SAN and is managed using the SDDPCM package. Which of the following must be considered?

  A. The latest version of SDDPCM should be included in the NIM lppsource for the upgrade.
  B. The IBM supplied scripts and procedures should be followed in order to migrate VIOS with SDDPCM.
  C. SDDPCM is now included in AIX 6. Upgrading of the package will occur automatically.
  D. SDDPCM must be upgraded immediately before the VIOS migration.
  B. The IBM supplied scripts and procedures should be followed in order to migrate VIOS with SDDPCM.

• Question 116:

  A new VIO Server environment has been created to support several VIO Clients. Disks have been assigned to both VIO Servers. Which of the following will ensure that disks can be mapped from both VIO Servers?

  A. chdev -dev sys0 -attr respol=disabled
  B. chdev -dev hdiskX -attr reserve_policy=no_reserve
  C. chdev -dev hdiskX -attr reservation=no
  D. chdev -dev sys0 -attr map=yes
  B. chdev -dev hdiskX -attr reserve_policy=no_reserve

• Question 117:

  A redundant pair of VIO Servers is used to virtualize the same SAN LUNs to a number of AIX LPARs. To ensure that Multipath 10 is correctly configured an administrator sets the appropriate device attributes on the vSCSI disks on the clients.

  One of the VIO Servers was shut down for 5 minutes to simulate a failure. After the VIO Server was brought back online, the administrator found that some LPARs recovered their storage paths automatically, yet some LPARs did not recover

  their paths at all.

  How can the administrator recover from the lack of path recovery?

  A. Reboot the client LPARs.
  B. Allocate both vSCSI adapters to the client LPARs.
  C. Update SDDPCM to a level higher than 2.1.2.3.
  D. Reduce the number of paths to the LUNS to 6 or less.
  A. Reboot the client LPARs.

• Question 118:

  A customer has two Power 770 systems in their environment. What is the minimum PowerVM version that will enable a flexible environment that can allow for seamless hardware maintenance?

  A. PowerVM Enterprise Edition
  B. PowerVM Enhanced Edition
  C. PowerVM Standard Edition
  D. PowerVM Express Edition
  A. PowerVM Enterprise Edition

• Question 119:

  A production application is hosted across two Power 750 Express servers, managed by an HMC. Each machine has 16 cores and 32GB RAM. Four 8GB LPARs are defined across the two systems and only 3 LPARs are active at once. Live

  Partition Mobility is used to maintain availability when maintenance is required.

  A test environment is being built across two Power 550 Express servers. Each machine has 8 cores and 16GB RAM. Four 4GB LPARs will be defined across the two systems, again only 3 will be active at once. To isolate the test and

  production environment, the test environment is managed by two IVMs.

  Two LPARs have been created on each test server. The administrator initiates a Live Partition Mobility operation to test moving LPARs between the servers.

  The migrlpar command fails to migrate the 4th LPAR with the following error:

  "The target managed system does not have enough available memory to create the partition."

  Because the 4th LPAR was inactive, it was expected that an inactive migration would be successful.

  Why would this inactive migration fail on the test environment, but succeed on the production environment?

  A. IVM-managed systems do not support inactive migrations.
  B. IVM-managed systems reserve RAM allocations, even for inactive LPARs.
  C. The target managed system already has the maximum number of partitions.
  D. Active Memory Sharing (AMS) or Active Memory Expansion (AME) is required for RAM over commitment.
  B. IVM-managed systems reserve RAM allocations, even for inactive LPARs.

• Question 120:

  After a hardware failure, a VIO server has been restored from a mksysb image on a NIM server. When the VIO server boots, the client LPARs have no network access? What is the cause of this problem?

  A. The VIO server was configured to remain as a NIM client.
  B. The backupios command was not run correctly.
  C. Automatic device recovery is not supported by NIM restores.
  D. The client LPAR virtual network adapters have not been recreated
  A. The VIO server was configured to remain as a NIM client.
