• Question 72:

  A system with two WPARs is reaching the memory limits imposed on them. Both have been set to a hard limit of 50%.

  WPAR1 has a peak from 8am-10am of 70% memory resources

  WPAR2 has a peak from 2pm-6pm of 65% memory resources

  At peak times the system may kill processes which request more memory, as paging space is exhausted.

  What action would allow the two partitions to run efficiently at the same time?

  A. Configure WPAR memory limits using shares, and then set a hard memory limit of 85%.
  B. Use DLPAR to add additional memory to the global environment.
  C. Configure the WPARs to run in passive mode.
  D. Increase paging space by 20% for WPAR1 and 15% for WPAR2.
  A. Configure WPAR memory limits using shares, and then set a hard memory limit of 85%.

• Question 73:

  What is the purpose of the Virtual Asynchronous Services Interface (VASI) during Live Partition Mobility?

  A. It is used by the Hypervisor to determine the placement of the mobile partition's threads.
  B. It is used by the Mover Service Partition to communicate with the Hypervisor.
  C. It is used to direct the Hypervisor's placement of the mobile partition's memory tables.
  D. It is used by the Hypervisor to coordinate the I/O movement between the Virtual I/O Servers.
  B. It is used by the Mover Service Partition to communicate with the Hypervisor.

• Question 74:

  A client is planning to purchase a Power 770 with 2 enclosures, and needs to have redundancy for multiple LPARs. Which of these solutions provides the most redundancy for the LPARs at least cost?

  A. Assign an IVE logical port from each enclosure to each LPAR. Assign an HBA from each enclosure to each LPAR.
  B. Create two VIO servers assigning IVE and HBA adapters from different enclosures. Assign a virtual Ethernet adapter from each VIO server to Setup NIB on the LPARs. Assign SAN mapped virtual SCSI disks from each VIO server and use MPIO on the LPARS.
  C. Create two VIO servers assigning IVE and HBA adapters from different enclosures. Configure SEA failover on the VIO servers and assign a virtual Ethernet adapter to the LPARs. Assign SAN mapped virtual SCSI disks from each VIO server and use MPIO on the LPARS.
  D. Create a VIO server with two IVE adapters from different enclosures. Configure EtherChannel on the VIO server and assign a virtual Ethernet adapter to the LPARs. Assign an HBA from each enclosure to each LPAR.
  C. Create two VIO servers assigning IVE and HBA adapters from different enclosures. Configure SEA failover on the VIO servers and assign a virtual Ethernet adapter to the LPARs. Assign SAN mapped virtual SCSI disks from each VIO server and use MPIO on the LPARS.

• Question 75:

  A system is being upgraded to newer hardware. What measurement can be used to make sure the new system has the correct capacity excluding disk and network?

  A. TPC-C
  B. SPECint
  C. ROLTP
  D. rPerf
  C. ROLTP

• Question 76:

  When creating a new LPAR, what should be considered when setting the maximum value for memory?

  A. On a given system, by default the Hypervisor reserves 2.5GB of the system memory, regardless of the maximum memory allocation for an LPAR.
  B. The maximum memory value should be a multiple of the desired memory and the Logical Memory Block (LMB) to ensure minimal Hypervisor memory overhead.
  C. The Hypervisor will reserve a fraction of the maximum memory value for page tables.
  D. Where the maximum value exceeds 32GB, the Barrier Synchronization Register value needs to be set appropriately in the LPAR profile.
  C. The Hypervisor will reserve a fraction of the maximum memory value for page tables.

• Question 77:

  A. amepat
  B. amelpar
  C. amemon
  D. amestat
  A. amepat

• Question 78:

  Which is the lowest edition of PowerVM that will permit redundant VIO Servers?

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

• Question 79:

  What configuration change must be made on a Power Systems server to allow a Host Ethernet Adapter (HEA) to be used as part of a Shared Ethernet Adapter (SEA) on a Virtual I/O Server?

  A. The HEA port must be set to promiscuous mode.
  B. Set the HEA Port Group Multi-Core Scaling value to 1.
  C. Enable 802.11Q protocol on the HEA port that will be assigned to the SEA.
  D. Set the "Allowable VLAN IDs" to the PVID of the VIOS Virtual Ethernet Adapter.
  A. The HEA port must be set to promiscuous mode.

• Question 80:

  An administrator adds a new virtual target device to a vhost adapter that already had target devices on it. The client LPAR does not detect the new disk and the following error has been logged in the errlog: IDENTIFIER: DF63A4FE Date/Time: Tue Mar 8 10:41:55 2011 Sequence Number 2205 Machine Id: 00C7654DB00 Node Id: vios1p1 Class: S Type: TEMP Resource Name: vhost3 Description Virtual SCSI Host Adapter detected an error Probable Causes Virtual SCSI Host Adapter Driver is an Undefined State Failure Causes Virtual SCSI Host Adapter Driver is an Undefined State Recommended Actions What is the most likely cause for this situation?

  A. The intr_lsi of the host adapter is set higher than that needed by the new drive
  B. The intr_priority of the host adapter is set lower than that needed by the new drive.
  C. The queue_depth parameter of the new drive is larger than those of the other drives provided by the host adapter
