A dual port Ethernet PCI Express adapter has failed on a Power 780. The one port that is used is the backing device for an SEA (Shared Ethernet Adapter) on a VIO Server. The VIO Server only has this one Ethernet adapter, no other network adapters are allocateD.Which devices must be in a ‘Defined’ state in AIX on the VIO Server prior to using the Hot Plug task from the ‘diagmenu’ command?
A.Two Ethernet adapters, one PCI bus.
B.Three Ethernet adapters, one PCI bus.
C.Two Ethernet adapters, one SEA interface, two PCI buses.
D.Three Ethernet adapters, one SEA interlace, three PCI buses.

An administrator wants to install a new VIO Server (VIOS) partition from a NIM server. When checking the VIOS media the administrator finds two files, mksysb_image and mksysb_image2.
Which of the following is the correct sequence of actions to prepare the mksysb resource for NIM installation of the VIOS partition?
A.Copy both mksysb_image files to hard disk. Define NIM mksysb resources.
B.Copy the mksysb_image file to hard disk. Define a NIM object. Create a SPOT using
mksysb_image2 as source.
C.Copy the mksysb_image2 file to hard disk. Define a NIM object. Create a SPOT using
mksysb_image2 as source.
D.Copy both mksysb_image files to hard disk. Combine the two files to create a third file and define this as a NIM object.

A client is running a two node active/passive cluster on AIX 6.1 and needs to migrate AIX versions while minimizing the time the cluster runs without a failover node available. They plan to migrate the passive node, before moving the resources off the active node to migrate it. Which of the following options will minimize the time that the passive node is unavailable?
A.Run a network-boot NIM migration from the NIM master on the current passive node.
B.Run a local migration from assigned a DVD-RAM media to remove any network overheads.
C.Run the migration using nimadm with cluster services still running on the passive node.
D.Run alt_disk_copy to create a backup to a spare disk prior to initiating a NIM migration.

第一个我选A, 如果
A.Two Ethernet adapters, one PCI bus.

U5803.001.xxxxxxCF-P1-C2 PCI-E capable, Rev 1 slot with 8x lanes pci9 pci10
这个例子我是认为他们占同样的PCI总线...
第二个正检查中....

考题这东西有的时候和实际上有点不同,所以有的时候不好选:
为什么我没有选B是因为下面, 这里面提到先要建立RESOURCE 如果已经有了那么就去第六步.....所以首先必须是RESOURCE....那么这个就是我选它的原因了.....

Using a mksysb image to install the base operating system on a NIM Client using SMIT
Follow this procedure for using a mksysb image to install the base operating system on a NIM Client using SMIT.

If the mksysb resource has already been created, skip to step 6. Otherwise, to create the mksysb resource, enter the smit nim_mkres fast path.
Select mksysb from the list of resource types that can be defined.
In the displayed dialogs, supply the values for the required fields. Use the help information and the LIST option to help you specify the correct values for defining your mksysb resource.
If the mksysb image does not exist, create it by supplying the values for the fields under System Backup Image Creation Options.
Note: If the mksysb image already exists as a file on the hard disk of the NIM master or client, no additional information is needed to define your mksysb resource.
Upon successful completion of this task, exit SMIT.
To use the mksysb resource to install a NIM client, enter the smit nim_bosinst fast path.
Select a TARGET for the operation.
Select mksysb as the installation TYPE.
Select the MKSYSB to use for the installation.
Select the SPOT to use for the installation.
In the displayed dialog fields, supply the correct values for the installation options or accept the default values. Use the help information or the LIST option to help you.
Run the SMIT dialog to install the NIM client.
If the client machine being installed is not already a running, configured NIM client, NIM will not automatically reboot the machine over the network for installation. If the client was not rebooted automatically from SMIT, initiate a network boot from the client to install it. For information about to initiating a network boot, see Booting specific machines over the network.
After the machine boots over the network, the display on the client machine will begin prompting for information about how to configure the machine during installation. Specify the requested information to continue with the installation.
Note: To perform a nonprompted installation, follow the instructions in Performing a nonprompted BOS installation to complete the prerequisite tasks.

我选如下作为答案.
D.chvopt
A.Open appropriate ports in the firewalls for the monitoring server.
B.Use chhmc -c syslog commanD.

我也在斟酌中，老外的题就是这样。。。

Note: If the mksysb image already exists as a file on the hard disk of the NIM master or client, no additional information is needed to define your mksysb resource.

题干中应该已经提了When checking the VIOS media the administrator finds two files, mksysb_image and mksysb_image2.
所以是不是直接跳过resource了？

另第三发，多谢裤衩兄

A customer has locally cloned an existing AIX installation. Some files in the Ietc directory need to be edited on the new clone. How can this be achieved without booting the new clone?
A.alt_rootvg_op-W
B.alt_rootvg_op -o
C.alt_disk_install -X
D.alt_disk_install -S

An administrator is managing a two node PowerHA cluster on AIX 7. The administrator needs to add a shared volume group made up of a single disk presented through redundant VIO Servers to each node. Running cfgmgr, one node configures the new disk as hdisk9 while the other node configures the same disk as hdisk10. The company has a naming standard which requires cluster disk to be configured with the same device names on all nodes. A number of scripts have been coded for this standard and will fail as a result of the different hdisk names. Which of the following is the quickest way to fix this?
A.Update any scripts to determine the cluster disk automatically.
B.Use the rendev command to rename the disks before they are useD.
C.User migratepv to reorder the disks on the second node to match the first.
D.Remove the other disks and add one by one using DLPAR in the correct order.

A system administrator must provide network access to a single VLAN for multiple partitions on a Power 795 server. The Power 795 server has a pair VIO Server (VIOS) partitions, with a Shared Ethernet Adapter (SEA) in each one. Each SEA will use a single-port Ethernet adapter as a backing device. Both SEAs must support network traffic so both adapters are used simultaneously.Network service must be resilient. All client partitions must be able to maintain network access to this VLAN through either VIOS partition if the other VIOS partition fails or is taken out of service. Which of the following configurations would satisfy this goal?
A.The SEAs are both connected to the same virtual switch. Both SEAs are configured for SEA failover. The client LPARs are configured with one virtual Ethernet adapter
B.The SEAs are each connected to separate virtual switches. Both SEAs are configured for SEA failover. The client LPARs are configured with one virtual Ethernet adapter.
C.The SEAs are both connected to the same virtual switch. Neither SEA is configured for SEA failover. The client LPARs are configured with NIB on two virtual Ethernet adapters.
D.The SEAs are each connected to separate virtual switches. Neither SEA is configured for SEA failover. The client LPARs are configured with NIB on two virtual Ethernet adapters.

A customer has a Power 770 and a Power 795 managed by a single HMC.The existing HMC has two network connections. The first adapter is connected to the general company network and uses a static IP address. The second adapter is connected to a network switch which also has connections to the Flexible Service Processors (FSP5) of the managed systems and acts as a DHCP server. It has been decided to add a second HMC for resilience. Which of the following is a supported method of configuring the new HMC, in relation to the existing HMC?
A.On the same public network On the same private network, using a different DHCP range
B.On a different public network On the same private network, using the same DHCP range
C.On the same public network On a different private network, using the same DHCP range
D.On a different public network On a different private network, using a different DHCP range

18题，应该是B，因为Power7不支持aix52,支持aix53 61 71，所以对aix52而言，只能用wpar方式的。
19题，应该选择C,让SMS对这个FC有认知
20题，应该是B
26题，如果MTU变少，每次发送都需要cpu一个操作，这样CPU消耗肯定更多了，所以应该选择c
32，D
35,A
39,b
44我也不明白！
