There are three data centers as shown in the exhibit. Two data centers need to be on line at all times and each data center can backup the adjacent data center. The IOCP is configured such that when there are no failures, some CHPIDs have paths defined for storage in all three data centers. All data centers are using Brocade DCXs interconnected using direct (no DWDM) single mode fiber at less than 3 km. Which three elements must be implemented? (Choose three.)
