• A、Shared Ethernet Adapters and Virtual SCSI services require separate Virtual IO Servers.
• B、Virtualized adapters require essentially the same Virtual IO Server resources regardless of adapter type.
• C、Shared Ethernet Adapters require significantly more Virtual IO Server resources than Virtual SCSI services.
• D、Virtual SCSI services require significantly more Virtual IO Server resources than Shared Ethernet Adapters.

第4题：

Companycom LPAR that is using a Virtual IO Server needs to be more highly available. How can this be accomplished using APV features?（）

• A、Reallocate the Virtual IO Server disks to the user LPAR
• B、Create a stripe-group within the Virtual IO Server to protect against disk failure
• C、Reconfigure the user LPAR to use both locally owned disk and a Virtual SCSI disk
• D、Create a second Virtual IO Server and reconfigure the user LPAR to mirror across both Virtual IO  Servers

第5题：

Companycom wants to use Virtual SCSI disks to boot multiple operating systems from the same disk. How will the volumes appear in the Virtual IO Server and how will the logical volumes appear in the partition?（）

• A、The Virtual SCSI disks are defined as logical volumes in the Virtual IO Server. The logical volumes appear as real devices (hdisks) in the client partitions. 
• B、The Virtual IO adapters are connected to a virtual host bridge. On the Virtual IO Server they are vdisks, on the client partition, the exported disks are visible as virtual disks. 
• C、The Virtual SCSI disks are represented in the ODM as a bus device whose parent is sysplanar0. Logical volumes will be assigned to the Virtual IO Server and virtual disks, vdisks, in the client partition. 
• D、The Virtual IO adapters are represented as adapter devices with the virtual host bridge as their  parent. On the Virtual IO Server they are vdisks attached to vscsi, on the client partition the exported disks are visible as virtual disks.
