第4题：

The workload requirement for a Web server running in Micro-Partitioned p5-550 has increased 300 percent over the past six months. The initial partition definitions assigned 0.5 processing units and one virtual processor to the Web server partition. Three months previously， an additional 0.5 CPU was added to the Web server partition. When the technical specialist attempted to allocate a further 0.5 CPU to this partition， no additional performance was achieved. Which of the following actions would most likely resolve the problem？（）

• A、Add another virtual Ethernet.
• B、Change the partition to be uncapped.
• C、Change the number of virtual processors to 2.
• D、Increase the amount of memory assigned to the partition by 300 percent.

第5题：

A Power 720 has AIX 6.1 and Linux partitions.During normal workloads there is more than enough memory available to the LPARs.  During month-end processing one partition becomes memory constrained.      What can help overcome this situation？（）

• A、Active Memory Sharing （AMS）
• B、Active Memory Expansion （AME）
• C、Integrated Virtual Memory （IVM）
• D、Memory Capacity on Demand （CoD）

第6题：

A customer has a system with a number of LPARs, one of which is running a supported version of Linux. Which CLI command can an administrator use to display the CPU and memory resource allocation of the Linux partition? （）

• A、cat /proc/usr/lparchk 
• B、cat /proc/ppc64/lparcfg 
• C、/var/adm/tools/res_list

A customer has an 8-way p650 running an application for about 200 users.  In the past， the requiredamount of memory and processors has increased proportionally to the number of new users.  The customer plans to increase users by 10% each year for the next three years.  Next year， a database will be added to the workload to support the users directly rather than being on a separate machine. What is the most likely result of this projected growth？（）

• A、Disk usage will increase in proportion to memory.
• B、The new database will demand much more memory.
• C、Memory demand will increase 10% for the next year.
• D、Processor demand will increase about 10% for the next year.
