IBM C4040-109 Online Questions & Answers

• Question 11:

  A virtual adapter with IEEE 802.1Q enabled for multiple VLANs has been created on a new VIO Server. This has been turned into a Shared Ethernet Adapter (SEA) but the SEA is not passing the tagged traffic to the outside world. Which of the following actions, when taken on the VIO Server, will fix the issue?

  A. Set the trunk priority is to 1.
  B. mkvdev -vlan ent[Ethernet device] -tagid [VLAN ID] for each PVID.
  C. Re-create the SEA with -vlan [VLAN ID] option.
  D. chvdev -sea en[Ethernet interface] -vlanid [VLAN ID].
  B. mkvdev -vlan ent[Ethernet device] -tagid [VLAN ID] for each PVID.

• Question 12:

  An administrator has removed a client LPAR and would like to unmap the virtual Fibre Channel adapter vfchost0 from the physical backing adapter fcs2. Which of the following commands will achieve this?

  A. rmvdev -vtd vfchost0
  B. vfcumap -vdev vfchost0 -dev fcs2
  C. rmdev -dev fcs2
  D. vfcmap -vadapter vfchost0 -fcp
  D. vfcmap -vadapter vfchost0 -fcp

• Question 13:

  An administrator is troubleshooting a network connectivity error on a POWER blade.

  Checking netstat, the administrator can see that the relevant adapter is "up and running". A ping test to the default gateway times out.

  Checking on another adapter, connected to the same LPAR, ping works as expected.

  What needs to be checked?

  A. If the switch module port for the adapter is enabled and plugged in
  B. If the mapping between network adapter and switch module port is correct
  C. If the MCS value is correctly sized for the number of LHEAs
  D. If the CIOv network adapter is installed in the correct slot
  C. If the MCS value is correctly sized for the number of LHEAs

• Question 14:

  An administrator would like to install a new Fix Pack on an existing VIO server. The Fix Pack has been mounted using NFS on /mnt. Which command should the administrator use to achieve this?

  A. installios -update_all -dev /mnt
  B. iosinst -update -install -accept -dev /mnt
  C. updateios -dev /mnt -accept -install
  D. geninstall -u -ac -d /mnt -f all
  C. updateios -dev /mnt -accept -install

• Question 15:

  A second virtual disk has been added to a SuSE Linux LPAR on the existing vhost0 adapter. What must be done for this disk to be recognized on the Linux LPAR?

  A. /usr/bin/cfgmgr
  B. /bin/kpartx -a -v /dev/sdb
  C. echo "- - -" > /sys/class/scsi_host/host0/scan
  D. /usr/bin/rescan-scsi-bus
  C. echo "- - -" > /sys/class/scsi_host/host0/scan

• Question 16:

  An LPAR was created on a POWER6 system with default processor/memory settings. It was migrated from the POWER6 system to a POWER7 system. Over time, that LPAR has been shutdown and restarted.

  An administrator now needs to migrate the LPAR back to the POWER6 system, but it fails to validate.

  There have been no changes in the LPAR profile, network, or in the SAN configuration.

  Which action will enable the operation to complete successfully?

  A. Set the processor mode to default on the source profile and restart the LPAR.
  B. Set the processor mode to POWER6 on the source profile and restart the LPAR.
  C. Set the processor mode to Shared on the source profile and restart the LPAR.
  D. Set the processor mode to Dedicated on the source profile and restart the LPAR.
  B. Set the processor mode to POWER6 on the source profile and restart the LPAR.

• Question 17:

  When planning for virtual disk redundancy on an AIX LPAR, which solution would provide the highest availability?

  A. N_Port ID Virtualization (NPIV)
  B. MPIO through redundant VIO Servers
  C. Disk mirroring on the VIO Servers providing the virtual disks
  D. Distinct vhost provided for each disk allocated by the VIO Servers
  B. MPIO through redundant VIO Servers

• Question 18:

  A systems service processor is being connected to a redundant HMC. Which of the following is required to support DHCP server on dual HMCs?

  A. The two HMCs must be on different subnets.
  B. The redundant HMC must have the 'Redundant DHCP Range' check box selected on ethernet ent0 configuration.
  C. Both HMCs must be running RMC on a shared private network.
  D. The first HMC must be set as primary DHCP range.
  A. The two HMCs must be on different subnets.

• Question 19:

  A company needs to implement a virtual environment on a Power 770 server using a Virtual I/O Server and a large number of clients. What network solution can be implemented on the Virtual I/O Server to maximize bandwidth for the clients?

  A. Link Aggregation
  B. Network Interface Backup
  C. Shared Ethernet Adapter failover
  D. VLAN mapping
  A. Link Aggregation

• Question 20:

  An administrator manages a Power 750 server for application development testing. Full system environments need to be deployed quickly to perform functional application testing. What is the fastest method for the administrator to deploy new AIX environments for the testing staff?

  A. Install a VIO server and install testing LPARs utilizing virtualized network and disks.
  B. Install a NIM server LPAR on the system and perform installations on testing LPARs through Virtual Ethernet adapters.
  C. Use alt_disk_install to maintain a new image on alternate disks on testing LPARs.
  D. Create a global LPAR and create test environments using WPAR.
  D. Create a global LPAR and create test environments using WPAR.
