IBM C4040-109 Online Questions & Answers

• Question 91:

  When many LPARs require large quantities of SAN LUNs, what is a benefit of leveraging NPIV over more traditional vSCSI virtualization?

  A. Multipath I/O
  B. Enhanced resilience
  C. Normalized throughput
  D. Reduced administration
  D. Reduced administration

• Question 92:

  An existing machine is configured with redundant VIO Servers with SEA failover. A number of VLANs are already configured and used by the hosted client LPARs. Two additional VLANs are required to be added to the deployment to support

  new growth.

  An administrator uses a DLPAR operation to add the additional VLANs to the existing Virtual Ethernet adapters. The attempt failed. They have updated the LPAR profile for both VIO Servers. Next they shutdown one of the VIO Servers and

  attempt to reactivate the LPAR. The following error is displayed:

  "HSCL0282 The virtual Ethernet adapter in virtual I/O slot 11 can't be defined because the partition with ID 2 already defines a trunk adapter in its virtual I/O slot 11. Please modify the profile accordingly and reactivate the partition."

  What is the cause of the failure?

  A. It is not possible to add new VLANs to an existing virtual adapter that is part of an SEA failover environment.
  B. The failed DLPAR operation has not been cleared prior to reactivation of the LPAR profile.
  C. The connectivity required for DLPAR operations has not been configured.
  D. The additional VLANs have not been added to the active VIO Server.
  A. It is not possible to add new VLANs to an existing virtual adapter that is part of an SEA failover environment.

• Question 93:

  An administrator is planning to update a server managed with Integrated Visualization Manager (IVM) from version 1.5 to version 2.2. Which of the following statements should the administrator take into consideration?

  A. The migration can only occur using a Serial Over LAN (SOL) console.
  B. The administrator should use the Advanced Management Module (AMM) interface to specify the location of the migration DVD.
  C. All client partitions should be shut down before starting the migration to avoid data corruption.
  D. The partition profile data will need to be saved before the migration and restored once the migration is complete.
  C. All client partitions should be shut down before starting the migration to avoid data corruption.

• Question 94:

  An administrator needs to add additional LPARs to a Power 770 server, but all of the available memory on the system is currently assigned to existing LPARs and is continually utilized. What solution can the administrator implement on the system to add the LPARs?

  A. Active Memory Expansion
  B. Active Memory Compression
  C. Virtual Memory Management
  D. Weighted Memory Allocation
  A. Active Memory Expansion

• Question 95:

  An administrator is configuring a new virtual Fibre Channel connection that will use NPIV to connect a client LPAR to a SAN.

  The administrator has created a client adapter in virtual slot 8 and a server adapter in virtual slot 600. The appropriate virtual adapter definitions have been successfully added into the client and VIO server profiles and a DLPAR operation to

  add the virtual adapters into both partitions.

  The administrator runs cfgmgr on the client partition but receives an error. The administrator then checks the definition of the client adapter in AIX

  

  Based on this information, what is the most likely cause of the error?

  A. The virtual Fibre Channel server adapters are not supported with virtual slot numbers higher than 512.
  B. The virtual server adapter has been incorrectly mapped to virtual slot 3 for the client.
  C. The virtual server adapter has not been mapped to a physical Fibre Channel adapter.
  D. The virtual Fibre Channel device driver has not been installed on the client.
  C. The virtual server adapter has not been mapped to a physical Fibre Channel adapter.

• Question 96:

  A Linux LPAR has been created and RHEL6 has been installed. The LPAR has the following characteristics: Processor Entitlement - minimum / desired / maximum

  1.0 2.0 3.0

  A DLPAR operation to add 1 processor entitlement fails. Which of the followings actions will resolve this issue?

  A. Upgrade to PowerVM Standard Edition.
  B. Set /proc/sys/kernel/rsct_dlpar to 1.
  C. Reboot the Linux LPAR and use the 64bit kernel
  D. Install the IBM Installation Toolkit for Linux.
  D. Install the IBM Installation Toolkit for Linux.

• Question 97:

  Which of the following is required when configuring an LPAR that will later be used for Live Partition Mobility?

  A. All physical I/O must be allocated as "Desired" in LPAR properties
  B. Virtual Fibre Channel adapters must be marked as "Desired".
  C. Virtual Ethernet adapters must be configured as EtherChannels.
  D. Virtual SCSI adapters must be marked as "Desired".
  A. All physical I/O must be allocated as "Desired" in LPAR properties

• Question 98:

  Certain configurations of Power 770 and Power 780 servers can be ordered with multiple IVE adapters. When designing a configuration to provide improved network availability what fact should be observed as a risk?

  A. 1Gbps and 10Gbps adapters may not be aggregated into a single logical link.
  B. The same model of IVE must be ordered for each building block.
  C. IVE adapters do not support hot-plug operations.
  D. An EtherChannel device created from adjacent IVE ports can result in broadcast storms.
  C. IVE adapters do not support hot-plug operations.

• Question 99:

  An administrator uses DLPAR on an active LPAR to add an additional VLAN ID into an existing virtual adapter used by the SEA. The operation fails with error HSC01221 stating that the Modification of Virtual I/O resources failed. The server being modified is a POWER6 595 running firmware version EH350_071. The VIO Server is at version 2.2.0.10 FP24Based on this information, what is the most likely cause for this error?

  A. The system firmware needs to be updated to EH350_085.
  B. The VIO Server needs to be updated to 2.2.0.10 FP 24 SP1.
  C. Dynamic addition of VLAN IDs to an existing virtual adapter are only supported at AIX 7.1.
  D. Dynamic addition of VLAN IDs to an existing virtual adapter are only supported on POWER7 hardware.
  B. The VIO Server needs to be updated to 2.2.0.10 FP 24 SP1.

• Question 100:

  When attempting to install a VIO client using NIM, an adminstrator finds that no disks are available for installation. The disks are provided by NPIV through the virtual Fibre Channel adapter as described here:

  

  Which of the following explains why is the administrator unable to see the disks?

  A. The virtual fibre channel device has not been assigned to the client.
  B. The HBA on the VIO server is not connected to the SAN.
  C. The fibre device drivers are missing from the SPOT.
  D. The LUNs have been incorrectly zoned.
  D. The LUNs have been incorrectly zoned.
