Actual exam question from IBM's C9030-644

Question #: 14
Topic #: 1

A customer is considering upgrading a z114 processor currently used as a standalone coupling facility (CF). The customer wants to upgrade to a z13s 2965-N10, but also wants to install additional capacity on this new z13s for two new LPARs running Linux workloads.
A sizing exercise has determined that the combined CF and Linux workload would total four ICFs, five IFLs, and 600 GB memory. The other systems in the customers environment are zEX12 servers.

Which of the following statements is true for this situation?

A. Integrated Coupling Adapter (ICA) cards can be installed in the zEC12 servers to improve performance.
