IBM(000-968)單項選擇題每日一練(2019.04.26)

A customer wants to consolidate storage from four IBM System p servers and one large IBM System i server on a high end disk subsystem. The customer does not have a SAN installed. The customer will require approximately 24 TB of capacity for System p and 20 TB of capacity for System i. The customer states that performance of the System i system is most important. Capacity， multi-path access， and replication functions are important for the System p servers. 
Which solution best satisfies the customer requirements（）

During a review of environmental requirements before ordering an IBM System z9 server and IBM System Storage DS8700， the customer states that the available power is 220 volts AC. 
Which feature should be included with the DS8700 order（）  

Two DS8700 systems have been proposed for a disk-to-disk BC solution. Each system has 200 TB installed， with a data change rate of 18% per day. Two 2 Gbps CWDM links are in place between the remote data centers with an average utilization rate of 55%. The proposed solution  
includes additional CWDM ports. 
Which of the following should justify the additional CWDM ports（）
