考题
A system administrator for a business recovery service center needs to test disaster recovery strategies for their clients running Linux. Each client has a different system configuration. Each time a client comes in, the system configuration of the managed system must change. What is the best way to handle this using LPAR?（）A、Create a system profile. Reconfigure the managed system by activating and deactivating the system profiles. B、Create one partition profile for each client. Reconfigure the managed system by activating the partition profiles for that client. C、Dynamically move processors and memory as needed into each logical partition. Reconfigure the managed system by activating and deactivating partition profiles. D、Dynamically move processors and memory into each logical partition on the server if additional resources are needed. Reconfigure the managed system by activating and deactivating the system profiles.
