Which recommendation will improve the resiliency of this environment?

A customer has a Parallel Sysplex running on LPARs spread across two z13 processors in the same data center location. Each z13 has multiple FICON Express8S channel paths to one shared DS8870 subsystem.

Which recommendation will improve the resiliency of this environment?
A . Install a second DS8880 and mirror the data.
B . Replace the FICON Express8S with FICON Express16S channels.
C . Implement FICON Dynamic Routing and Forward Error Correction.
D . Add FICON Directors and Inter-Switch Links to the infrastructure.

Answer: C

Explanation:

With the IBM z13 and IBM z13s servers, FICON channels are no longer restricted to the use of static SAN routing policies for ISLs for cascaded FICON directors. The z Systems servers now support dynamic routing in the SAN with the FICON Dynamic Routing (FIDR) feature.
