質問 1

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）The failed DLPAR operation has not been cleared prior to reactivation of the LPAR profile.

（B）The connectivity required for DLPAR operations has not been configured.

（C）It is not possible to add new VLANs to an existing virtual adapter that is part of an SEA failover environment.

（D）The additional VLANs have not been added to the active VIO Server.

質問 2

A dedicated LPAR has two dedicated Fibre Channel HBAs assigned to it.
In order to reduce the amount of hardware, the LPAR will be migrated to a currently
running VIO server.
The administrator collects some server performance from the VIO server and notices that the I/O peaks at 5.5Gbits and runs at an average of 4Gbits per second.
The VIO Server runs two dual port 8Gbit FCS cards, so the load is not affected by other LPARS on the VIO Server.
Which of the following is the most cost-efficient configuration for the VIO client?

（A）Dedicate two new Fibre Channel HBAs to the VIO Server and use them to exclusively host the vSCSI disks for the new client partition.

（B）Install SDDPCM drivers onto the VIO Server, set up the client LPAR and run the following command: "datapath priorities vhostX fscsi0 fscsi1 fscsi2 fscsi3".

（C）Assign vSCSI disk for the new client LPAR through prioritized channels.

（D）Assign one of the ports in the 8Gbit Fibre Channel HBA, using NPIV directly to the new client partition.

質問 4

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）Virtual Memory Management

（C）Active Memory Compression

（D）Weighted Memory Allocation

質問 5

A number of POWER7 servers have been ordered to replace an existing infrastructure of POWER4 machines. All existing LPARs will be manually recreated on the new machines, preserving the installed operating systems.
An administrator is planning to attach the POWER7 machines to the subnet, allowing the LPARs to keep their hostname and IP addresses. The NIM server that will be used to restore the LPARs on the new machines allows its clients it initiate NIM client commands.
What needs to be considered to preserve the ability to restore an existing LPAR on the new infrastructure?

（A）The POWER7 machines will be managed by a different HMC.

（B）LPAR profiles need to be consistent between old and new infrastructure.

（C）Prior to migrating to POWER7, the AIX levels of the existing LPARs may need to be updated.

（D）NIM client CPU ID validation should be disabled before installation on the new hardware.

質問 6

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）IVE adapters do not support hot-plug operations.

（B）The same model of IVE must be ordered for each building block.

（C）1Gbps and 10Gbps adapters may not be aggregated into a single logical link.

（D）An EtherChannel device created from adjacent IVE ports can result in broadcast storms.

質問 7

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:

What is the most likely cause for this situation?

（A）The max_transfer parameter of the new drive is smaller than the rate already reported by the host adapter

（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

（D）The intr_lsi of the host adapter is set higher than that needed by the new drive

質問 8

An administrator would like to create AIX 5.2 Workload Partitions (WPARs) on a new POWER7 system.
Which of the following is the minimum needed to achieve this?

（A）AIX 7.1 Express Edition AIX 5.2 Workload Partitions for AIX

（B）PowerVM Enterprise Edition AIX 5.2 Workload Partitions for AIX

（C）PowerVM Standard Edition WPAR Manager 2.1

（D）AIX 7.1 Enterprise Edition WPAR Manager 2.1

質問 9

The wlmstat -@ 2 command has been run from a global environment with the following results:

What action can an administrator take to set limits, so that both server1 and server2 use the same amount of CPU resources?

（A）Use the syncwpar -E command to copy the CPU resource allocation from server1 to server2.

（B）Use the chsysres command to assign the same CPU attributes to both servers.

（C）Use the chwpar -R command to set the CPU attributes for each server.

（D）Use the cpu_deallocate -P command to reduce the CPU resources on server2

質問 10

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）LPAR2 has "Allow when partition inactive" in the Processor Sharing section CHECKED in its profile

（B）LPAR1 has "Allow when partition active" in the Processor Sharing section CHECKED in its profile

（C）LPAR1 has "Allow when partition active" in the Processor Sharing section NOT CHECKED in its profile

（D）LPAR2 has "Allow when partition inactive" in the Processor Sharing section NOT CHECKED in its profile
