Due to a recent change in government regulations， Company.com needs to create two independent but synchronized copies of their data. These copies must be contained in separate storage device a minimum of 100 km apart. The customer has capacity in two systems that meet the criteria， one with SSA disk and the other is FAStT. What facility can be used to manage this issue？（）A、 Two independent copies of the data can be created and synchronized using the "HACMP/XD://HAGeo"B、 The existing disks can be incorporated a single storage unit using the optional product "HACMP/XD://PPRC"C、 AIX can create a mirrored logical volume across the two systems that would be accessible from either systemD、 AIX can use the multi path IO subsystem to spread the information across the devices and keep the copies separated
