IBM C4040-109 Online Questions & Answers

• Question 31:

  The VIO servers in a Power Systems server have already been installed and the LUNs have been mapped to their vhosts as virtual scsi disks. When defining a client LPAR, the administrator wants to map a virtual client SCSI adapter to a server adapter in one of the VIO servers.

  C. This information is only available when using internal disks.
  D. PowerVM Enterprise Edition is required for this feature .
  A. The information becomes available when the clients are booted.

• Question 32:

  A new virtual SCSI adapter has been added to a SuSE Linux client using DLPAR. By what method will the adapter be added to the system?

  A. The IBM.DRM service dynamically adds the adapter.
  B. The administrator runs the echo "- - -" > /sys/class/scsi_host/host0/scan command.
  C. The adapter will be recognized after rebooting.
  D. The administrator runs the refresh -s IBM.ServiceRM command.
  A. The IBM.DRM service dynamically adds the adapter.

• Question 33:

  An architect is considering whether to specify vSCSI or NPIV for the rootvg disks in a new virtualized environment. Storage is to be provided by an IBM San Volume Controller (SVC) and controlled using SDDPCM. Which of the following is an advantage of using vSCSI technology instead of NPIV?

  A. Support for vSCSI devices is included within base AIX, removing the need to install device drivers at the client level.
  B. Queue depths higher than 20 for rootvg disks are supported with vSCSI.
  C. vSCSI allows for client level logical volume mirroring for rootvg, providing enhanced protection.
  D. vSCSI provides active/active multi pathing, allowing I/O requests to be distributed between dual VIOS partitions
  A. Support for vSCSI devices is included within base AIX, removing the need to install device drivers at the client level.

• Question 34:

  To prevent frames being dropped as a result of network congestion on high speed links, IBM recommends enabling the use of pause frame on compatible switches and IVE adapters. Which attribute enables pause frames?

  A. Flow Control
  B. Jumbo Frames
  C. Port Group MCS
  D. 802.3ad
  A. Flow Control

• Question 35:

  An administrator has created a virtual media repository to hold images for a file backed virtual optical device. The administrator would now like to load an ISO image, aix7.iso into the repository. Which of the following commands will achieve this?

  A. loadsp -sp aix7 -fb aix7.iso
  B. loadopt -vtd aix7 -disk aix7.iso
  C. mkrep -vopt aix7 -file aix7.iso -fb
  D. mkvopt -name aix7 -file aix7.iso -ro
  D. mkvopt -name aix7 -file aix7.iso -ro

• Question 36:

  An administrator has a Power 720 with 64GB of memory and Active Memory Expansion (AME).

  An LPAR has only 10GB of memory available and an application has been sized at 15GB of memory. The administrator runs amepat to determine an efficient expansion factor. Based on the output, an expansion factor of 1.6 has been

  chosen.

  How should this be configured in the LPAR?

  A. Enter 16GB as 'desired', enter 1.6 in the Active memory expansion factor field.
  B. Enter 10GB as 'desired', enter 1.6 in the Active memory expansion factor field.
  C. Enter 10GB as 'desired' and modify/etc/ame.conf with AME_RATIO=1.6.
  D. Enter 16GB as 'desired' and modify/etc/ame.conf with AME_RATIO=1.6.
  B. Enter 10GB as 'desired', enter 1.6 in the Active memory expansion factor field.

• Question 37:

  While trying to reject recent updates to the VIOS, an administrator received an error message stating that a file set may not be rejected because a dependent file set is committed. Which command can be used to overcome this error?

  A. updateios -reject-f
  B. updateios -remove
  C. updateios -commit -u
  D. updateios -cleanup
  B. updateios -remove

• Question 38:

  An administrator tries to dynamically increase the processor capacity entitlement of LPAR1 from 1.0 to 2.0. The current entitlement is 1.0 and the maximum is set to 3.0.

  The operation fails. When the administrator adds up the number of processors in use by the currently running LPARs, there are 4 processors available. The administrator also notes that LPAR2 is inactive.

  What is the cause of this failure?

  A. LPAR1 has "Allow when partition active" in the Processor Sharing section CHECKED in its profile
  B. LPAR2 has "Allow when partition inactive" in the Processor Sharing section NOT CHECKED in its profile
  C. LPAR2 has "Allow when partition inactive" in the Processor Sharing section CHECKED in its profile
  D. LPAR1 has "Allow when partition active" in the Processor Sharing section NOT CHECKED in its profile
  B. LPAR2 has "Allow when partition inactive" in the Processor Sharing section NOT CHECKED in its profile

• Question 39:

  A VIO server requires redundancy on its Shared Ethernet Adapter (SEA). The SEA is backed by physical adapter ent0 and virtual adapter ent2, ent0 and ent1 are the interfaces on a dual-port Ethernet adapter.

  What network redundancy technique should be suggested?

  A. ent1 should be used to set up a Network Interface Backup through 'smitty etherchannel1. The new Etherchannel adapter should be used as the backing device for the SEA
  B. ent1 should be used to set up Link Aggregation through 'smitty linkagg1. The new Link Aggregation adapter should be used as the backing device for the SEA
  C. Create a new SEA using another virtual Ethernet adapter on the VIO Server and assign ent1 as the backing device. Assign this SEA to the clients and setup Link Aggregation on the clients.
  D. Setup the SEA failover control channel to use the ent1 physical adapter as the backup control channel.
  A. ent1 should be used to set up a Network Interface Backup through 'smitty etherchannel1. The new Etherchannel adapter should be used as the backing device for the SEA

• Question 40:

  An administrator is creating Virtual IO servers (VIOS) on a new POWER7 server, anticipating that Live Partition Mobility (LPM) will be used in the environment. Which action must be taken before LPM operations can begin?

  A. Ensure that AIX Enterprise Edition is loaded on the VIO server partition.
  B. Check the Mover Service Partition box on the partition properties panel on the HMC.
  C. Create the same number of VIOS partitions on all servers.
  D. Configure SEA failover for all VIOS partitions
  B. Check the Mover Service Partition box on the partition properties panel on the HMC.
