第2题：

A healthcare customer has an IBM System i server and an HP-UX server. They have high performance I/O， image-based， and archival applications. The customer has asked the IBM team  for guidance on IBM DS8000 disk technologies.  Which DS8000 disk technology would provide the best performance without regard to cost to meet the customer requirement（）

第3题：

Upon announcement，the specific details surrounding the Virtual I/O Server requirements and performance are still being defined.  The customer has engaged IBM to provide a server consolidation solution and would like to take advantage of the VIO Server benefits. How should the pSeries technical specialist best address this？（）

• A、Design the solution and present it confidently so the customer does not question it.
• B、Design the solution and ensure the customer understands the unknowns with the new technology.
• C、Explain to the customer that the VIO Server does not benefit them when doing server consolidation so it has not been configured.
• D、Explain to the customer that the details surrounding the VIO Server have not been clearly defined so designing a solution is premature.

第4题：

A customer has an x445 and uses the internal LSI adapter to manage two 146GB drives in the chassis.  The customer is noticing performance issues when deploying a database with significant write activity on the internal drives.  Should they consider using a ServeRAID-6M with 256MB of cache instead， and why or why not？（）

• A、Yes， the internal LSI SCSI adapter has no write cache.
• B、Yes， the internal LSI SCSI adapter is unreliable.
• C、No， the downtime to install the card and reformat the drives would be cost prohibitive.
• D、No， there will be no performance benefit， because drive performance is the bottleneck.

第5题：

An existing IBM customer has some iSeries servers in their environment.  The customer is adding an x366 server with an RSA-II installed for their Microsoft Client/Server applications.  The customer wants to consolidate the storage and centralize the backup of the iSeries and xSeries platforms.  Which of the following will accomplish this？（）

• A、Share the data over the Ethernet LAN.
• B、Install the IXA Adapter in the iSeries server.
• C、Install the IXA Adapter in the xSeries server.
• D、Attach both servers to an IXS switch.

第6题：

An administrator recently installed a new array controller into a server. When the server is running POST the controller does not appear as present. Which of the following could be the reason for this?（）
