A customer wants to install an IBM BladeCenter infrastructure but is concerned about the cost of the full fabric internal fibre switches. Consequently， the customer is considering an N_Port ID Virtualization （NPIV） capable switch. Which of the following should be mentioned to the customer regarding the NPIV switch？（）

• A、Youcan not use an NPIV switch in the same IBM BladeCenter chassis as a Cisco Intelligent Ethernet Switch
• B、Using blade servers with the NPIV switch will require morefibre ports on the external fibre switch
• C、Storage devices likeFibre Channel Tape and Disk cannot be attached to the NPIV Switch but must connect to a core fabric switch.
• D、The NPIV switch will count against the number of domains in a fabric
