IBM Assessment: Power Systems Virtualization Technical Support for AIX and Linux -v2 認定 A4040-109 試験問題:

1. An administrator is planning to install a new WPAR and intends to use Live Application
Mobility between source and target Power Systems servers.
What must be considered when configuring the storage layout of the WPAR?

A) NPIV backed SAN devices must be mapped to the global environment on the source and target servers.
B) NFS filesystems must be available on the source and target global environments and the WPAR.
C) Shared NPIV storage must be mapped to both source and target systems.
D) The /opt, /usr and /proc filesystems must be backed by NFS storage on a WPAR.

2. An administrator would like to determine the virtualization capabilities of some attached storage before proposing a new virtualization strategy. To determine the capabilities of the attached storage, the administrator runs chkdev and receives the following result:
padmin:vio1:/home/padmin>chkdev -dev hdisk1 NAME: hdisk1 IDENTIFIER: 382136005076801710072480000000000791F04214503IBMfcp PHYS2VIRT_CAPABLE: NA VIRT2NPIV_CAPABLE: YES VIRT2PHYS_CAPABLE: YES
Based on the output above, which one of the statements is true?

A) The disk is presented by vSCSI and is NPIV capable.
B) The disk can only be presented as a physical disk.
C) The disk can be presented by NPIV only.
D) The disk can be converted to NPIV with data loss.

3. An administrator is preparing to upgrade the environment's dual Virtual I/O servers (VIOS) from V1.2 to V2.1
What must considered in preparation for this upgrade?

A) The VIOS must be upgraded to the latest fixpack of V1.5 before upgrading to V2.1.
B) All client LPARs must be shutdown as both VIO servers have to be upgraded to V2.1 at the same time.
C) VIOS V2.1 requires AIX clients to be running AIX V6.1 at a minimum.
D) The only upgrade method that will be supported is using NIM because the current VIOS is lower than V1.3.

4. An administrator is trying to perform Live Partition Mobility (LPM) between physical systems managed by the same HMC. The VIO Servers (VIOS) on each physical system are connected to the same SAN. The client LPARs will use virtual SCSI (vSCSI) disks. The SCSI adapter slot numbers are between 11 and 20.Each client LPAR has a unique name. The network used by the client LPARs use Logical Host Ethernet adapters (LHEA).The PowerVM Enterprise edition is being used. No EtherChannel has been configured. Why are LPM activities failing?

A) The ssh keys have not been exchanged between the two VIO servers.
B) This LHEA configuration is not supported for LPM.
C) Multiple MSP (mover service partitions) were configured.
D) The SCSI adapter slot numbers are too high.

5. A customer is in the process of configuring a redundant pair of VIO Servers. They need to test that SEA failover has been correctly enabled.
Which command can the padmin UserID use to verify which SEA is currently the primary interface?

A) fcstat
B) vasistat
C) entstat
D) seastat
