Companycom needs to run a 32 bit kernel under AIX 5.3. What steps need to be done to accomplish this with the least disruption since the system is already installed with a 64 bit kernel?（）

A.Reload the operating system and select 32 bit kernel on initial install.
B.Repoint the symbolic link of /unix to unix_mp. Perform a bosboot and reboot the partition.
C.Use the SMIT menu to select 32 bit versus the 64 bit kernel. Select 32 bits and reboot the partition.
D.Go into SMIT and select 32 bit kernel. Run the /usr/sbin/bootinfo -K command， and ensure that the kernel has been changed.

单项选择题Companycom has seven days of vmstat data on a p5 590. The server has a total of four test dev LPARs and 4 production LPARs of one processor each. On the four test dev LPARs, the data shows 90-95% peak utilizations with a duration of from 5 to 10 minutes. The average utilizations of all LPARs were between 15-30%. All of the applications have different times when they peak. What is the best configuration to fully utilize the processor resource?（）

A.Set up the server in SMP mode and use WLM to manage resources effectively
B.Set up eight dedicated LPARs and use DLPAR to manage resources effectively
C.Set up a shared pool with eight capped LPARs including production and test/dev
D.Set up a shared pool with eight uncapped LPARs with priority weight to Production

单项选择题Acompanywantstobuymemoryefficientlyontheirp5590toallowforthebestperformance.Whatisthebestpracticeforaddingmemoryforperformance?（）

A.Install more cards of smaller capacity and same size across MCMs. Use DDR2(dual data rate) memory if using HPC (High Performance Computing).
B.Install fewer cards of larger capacity of the same size across MCMs. Servers with one processor book must have a minimum of four memory cards installed.
C.Intermix DDR1 and DDR2 memory so that partitions requiring the higher performance can take advantage of them. Half of the available memory slots in the system should contain memory.
D.Use fewer higher density memory cards so that a few memory slots are left open for future growth. Each processor book provides sixteen memory card slots. The p5 590 supports a maximum of 64 memory cards.

B.pSeries eWLM can create tiers while pSeries WLM can create classes.
C.pSeries eWLM is implemented over multiple O/S images while pSeries WLM is implemented within an individual O/S image.
D.pSeries eWLM is implemented within an individual O/S image while pSeries WLM is implemented over multiple O/S images.
