A. VPM
B. VIOS
C. IVM
D. AMM
正解：B

質問 9：
A POWER7 server is being configured with 1 hosting IBM i partition and 4 client IBM i partitions. All partitions will run IBM i 7.1, TR4. The hosting partition is providing network support to the client partitions and needs both redundancy and best bandwidth.
What connectivity on the host partition will support these requirements?
A. Configure two or more Ethernet lines. Create a Virtual IP address for the host partition. Configure Showler routes to the local network for load balancing.
B. Configure two or more Ethernet lines. Use the lines to create redundant bridges to the internal vLANs used by the client partitions.
C. Using two or more physical Ethernet resources configure an aggregated link to the switch and use this for IP address of the host partition.
D. Using two or more physical Ethernet resources configure an aggregated link to the switch and use this for the bridge to the internal vLANs used by the client partitions.
正解：D

3. A customer has several client IBM i partitions hosted by a single VIO Server. The system has one Shared Ethernet Adapter. The administrator has noticed that network performance is significantly degrading as traffic increases. The system workload has not changed.
Which statement describes a possible cause of this problem?

A) Virtual Ethernet is being used instead of physical adapters.
B) Simultaneous Multi-Threading is enabled but single-threaded workloads are running.
C) TheVIOServer is also hosting vSCSl, and the threading option is disabled on the Shared Ethernet Adapter
D) There are insufficient vLANs configured to support the network traffic.

4. An optical drive is owned by a VIO Server and shared between multiple IBM i partitions as virtual optical devices.
An administrator wants to use the virtual optical device on an IBM i partition, but WRKHDWRSC *STG shows that the virtual IOP is "Inoperative."
After verifying that the device is correctly allocated to the partition, what action should be taken?

A) On the HMC, modify the host partition profile so that the vSCSI adapter is configured for "Any client partition can connect".
B) In SST, IPL the virtual IOP and vary on the device
C) On the HMC, select the vSCSI adapter and, under the Advanced option, select the option to Recover the Adapter.
D) Vary off the device on the partition which is currently using the optical drive.
