  A. Unselect the processor sharing options in the LPAR profile.

• Question 82:

  A customer is planning to purchase a fully populated Power 795. There are 65 applications which need to run and all need an AIX 7 environment. The architect is considering whether to use an LPAR for each application or to use a single large LPAR and have a WPAR for each application.

  What must be considered before creating the environment?

  A. There is a limit of 64 WPARs in any AIX V7 global environment.
  B. An activation key for LPARs with more than 128 processors is required.
  C. There is a limit of 32 Processors in a WPAR.
  D. Multiple IVE adapters are required to support all the partitions.
  B. An activation key for LPARs with more than 128 processors is required.

• Question 83:

  A customer is planning a new multi-tiered web based retail solution. The solution will be implemented on AIX, running on POWER7 based servers. Several options are being considered, including one enterprise class system, two mid-range systems, or several entry level systems.

  Which of these documents will allow for an easy side-by-side comparison of the various models in the Power Systems range?

  A. AIX From Strength to Strength
  B. POWER7 Systems Facts and Features
  C. Redpaper: IBM Systems Virtualization: Servers, Storage, and Software
  D. IBM Power Systems Comparison Manual
  B. POWER7 Systems Facts and Features

• Question 84:

  Requirements for a disaster recovery site are being collected. When considering restoring a VIO Server mksysb to disaster recovery hardware, what is required to ensure automatic virtual device recreation?

  A. LPAR profiles must be accurately recreated on the foreign machine
  B. Backups of both mksysb and user-defined structures are required from the VIO Server
  C. The foreign machine must be of the same model and type
  D. Configuration of the existing HMC needs to be preserved
  A. LPAR profiles must be accurately recreated on the foreign machine

• Question 85:

  An administrator is attempting to remove a virtual adapter from an AIX partition using an HMC running V7R7.2. The DLPAR operation is failing with the following message:

  "Virtual adapters that are marked as required cannot be dynamically removed from the partition. Please change your adapter selections and try the operation again."

  How can the administrator remove the virtual adapter while minimizing any downtime?

  A. Remove the virtual adapter from the partition profile and reactivate the partition.
  B. Modify the active properties for the partition so that the adapter is not required for partition activation and repeat the DLPAR operation.
  C. Modify the last activated partition profile so that the adapter is not required for partition activation and repeat the DLPAR operation.
  D. Select the 'Force' option when performing the DLPAR operation.
  C. Modify the last activated partition profile so that the adapter is not required for partition activation and repeat the DLPAR operation.

• Question 86:

  An architect has been given the task of incorporating some new Power Systems servers running AIX 7 into an existing data center which is supported by a legacy SAN.

  The new servers will need to be connected to the SAN, and the LPARs on the servers will each have access to a Fibre Channel Tape using virtualized devices.

  Which action will the architect need to take?

  A. Check that the SAN switches support NPIV.
  B. Use the legacy Fibre Channel device driver in AIX.
  C. Specify that AIX Enterprise Edition must be used.
  D. Put the tape drive into the same zone as the HBA in the VIOS.
  A. Check that the SAN switches support NPIV.

• Question 87:

  A customer has four LPARs: VIO1, VIO2, LPAR1 and LPAR2

  VIO Servers (VIOS) are configured with SEA adapter failover and 802.1Q is enabled on the LPARs.

  During scheduled maintenance, VIO1 is brought down and the SEA failover happens automatically.

  However, network traffic is not leaving the VIO for LPAR1.

  The SEA interfaces are setup as follows:

  VIO1 - SEA

  PVIDs 55,60,65,70

  VIO2 - SEA

  The LPARs have their virtual network devices setup as follows:

  LPAR1 - Adapter ID 55 - VLAN ID 75

  LPAR2 - Adapter ID 60 - VLAN ID 45

  What is the reason for the networking problem?

  A. LPAR1 has the wrong VLAN ID configured.
  B. VIO2 has the wrong VLAN IDs configured.
  C. The LPARs have the wrong adapter IDs configured.
  D. The LPARs and the VIO servers are on different subnets.
  B. VIO2 has the wrong VLAN IDs configured.

• Question 88:

  When trying to suspend an LPAR, the process fails during the validation stage. Which of the following must also be correctly configured in order for this process to successfully complete?

  A. Reserved Storage Device Pool
  B. Dual VIO servers
  C. PowerVM Express Edition
  D. N_Port ID Virtualization
  A. Reserved Storage Device Pool

• Question 89:

  A company has a VIO server supporting several infrastructure LPARs, including a NIM server, several NFS servers, and a document management server. Network connectivity is provided from the VIO server through the 1Gb IVE.

  The NIM clients frequently receive "NFS Server not responding" errors during installations due to the volume of traffic to the server.

  When planning an upgrade to POWER7 hardware, which action will minimize these errors?

  A. Share the IVE directly to the LPARs.
  B. Implement Jumbo Frames on the 1Gb IVE adapters.
  C. Implement a 10Gb network infrastructure.
  D. Assign dedicated 1Gb adapters to each LPAR.
  C. Implement a 10Gb network infrastructure.

• Question 90:

  When planning a deployment what should be noted about the Virtual Media Repository when compared to other storage visualization offered by a VIO Server?

  A. The repository is vulnerable to VIO Server outage.
  B. Only AIX and Linux LPARs can be clients of the repository.
  C. DVD media must be virtualized through the repository in read-only mode.
  D. Items within the repository must be virtualized through an NPIV adapter.
  A. The repository is vulnerable to VIO Server outage.
