Companycom is planning a p5 595 running AIX 5L 5.3 LPARs. They would like to design the system using physical resources with maximum resource efficiency. One LPAR requires a peak load of 30 processors during the week with a low of 1 processor required on the weekend. The other LPAR requires only a single processor most of the time, but needs at least 24 processors at the beginning of the weekend to finish its weekly processing in the window allocated. Which of the following solutions is most appropriate to continuously maximize resource use for these two LPARs?()
A、Dynamic LPAR
B、Workload Manager
C、Partition Load Manager
D、Shared Processor Pools

An administrator has setup three partitions using shared pool with 2 processing units. They are activated in the following sequence: Partition one: Min. = 1.0, max = 2.0, desired = 1.5 Partition two: Min. = 1.0, max = 2.0, desired = 1.0 Partition three: Min. = 0.1, max = 1.0, desired = 0.8. What is the outcome?()
A、Partition one starts and has 2.0 processors allocated. Partition two does not start. Partition three does not start.
B、Partition one starts and has 1.0 processors allocated. Partition two starts and has 1.0 allocated. Partition three does not start.
C、Partition one starts and has 1.5 processors allocated. Partition two does not start. Partition three starts and has 0.8 processors allocated capacity.
D、Partition one starts and has 1.5 processors allocated. Partition two does not start. Partition three starts and has an allocated capacity of 0.5 processors.
