Exam 500-325 topic 1 question 45 discussion

the answer is A

A is the answer: SAN/NAS (top) General Guidelines Adapters for storage access must follow supported hardware rules (click here). Cisco UC apps use a 4 kilobyte block size to determine bandwidth needs. Design your deployment in accordance with the UCS High Availability guidelines (see http://www.cisco.com/en/US/solutions/collateral/ns340/ns517/ns224/ns944/white_paper_c11-553711.html). 10GbE networks for NFS, FCoE or iSCSI storage access should be configured using Cisco Platinum Class QOS for the storage traffic. Ethernet ports for LAN access and ethernet ports for storage access may be separate or shared. Separate ports may be desired for redundancy purposes. It is the customer's responsibility to ensure external LAN and storage access networks meet UC app latency, performance and capacity requirements. In absence of UCS 6100/6200, normal QoS (L3 and L2 marking) can be used starting from the first upstream switch to the storage array. With UCS 6100/6200
