What data should the Client Technical Specialist ensure that the customer collect on the zEC12 and the new z13 to verify the performance expectations have been met?

A customer is currently running several LPARs on a zEC12 with one dominant production LPAR, which consumes most of the CPU capacity. During the Technical Delivery Assessment (TDA), the customer mentions the performance of this LPAR is critical to a successful implementation.

What data should the Client Technical Specialist ensure that the customer collect on the zEC12 and the new z13 to verify the performance expectations have been met?
A . RMF CPU Reports for a peak week.
B . The total numbers of LPARs configured with the level(s) of z/OS that are active for each LPAR for both the zEC12 and the z13.
C . RMF CPU and Workload Reports for a peak week.
D . CPU MF Counters capturing the cache and memory hierarchy information for the zEC12 and z13.

Answer: C

Explanation:

When RMF is running in a Processor Resource/Systems Manager (PR/SM) environment in LPAR mode, the Partition Data Report section of the CPU Activity report provides data about all configured partitions active at the end of the reporting interval, independent of the operating system running in each partition.
