質問 5：
The exhibit represents a report from Capacity Magic. A customer wants to implement a mixed Open and System z environment. They will be using a combination of SSD, SAS and Nearline SAS drives. System z will require PAV. The NL-SAS drives will be used for FlashCopy targets for Open Systems and for Historical Report Data for z/OS. They wish to use Metro Mirror to replicate the Opens Systems production data to a remote site.
Which of the following best describes the minimum license requirements?
A. OEL = 173TB, MM = 87TB, FlashCopy = 48TB1 PAV = 87TB, FICON = Yes
B. OEL = 258TB, MM = S7TB, FlashCopy = 87TB, PAV = 87TB, FICON = Yes
C. OEL = 258TB, MM = 141TB, FlashCopy = 141TB, PAV = 1 17TB, EICON = Yes
D. OEL = 258TB, MM = 258TB, FlashCopy = 258TB, PAV = 258TB, EICON = Yes
正解：C
