A.All of the partitions can be managed in one group mixing dedicated and shared processors. PLM will move resources in the group as setup in the PLM profiles. 
B.PLM handles memory, dedicated and shared processor partitions. All the partitions in a group must be of the same processor type. PLM moves I/O resources between partitions based on PLM policy files. 
C.PLM handles memory, dedicated and shared processor partitions. The policy file, once loaded, is static and has no knowledge of workload on the managed partitions. PLM is supported for partitions that are running AIX 5.2 or i5OS. 
D.All of the partitions in a group must be the same type, either all dedicated processor partitions or shared processor partitions. One PLM Server can manage multiple groups of partitions. PLM does not move resources between groups.

A.All Service Agent transactions are inbound requests secured by encryption (cryptographic processor card) Kerberos, and Hypertext Transfer Protocol Secure (HTTPS). 
B.The AT&T Global Network Services (AGNS ) phone connection generates system IDs and passwords for the client every six months. Service Agent has no inbound capability.
C.All Service Agent transactions are outbound requests secured by encryption (Hypertext Transfer Protocol Secure (HTTPS) or POST). Service Agent has no inbound capability. 
D.The transmissions from Service Agent can be either by Internet or the AT&T Global Network Services (AGNS) phone connection. Service Agent transactions are inbound requests generated by a point to point connection.
