A network design engineer is asked to design a SAN for a company. Which three underlying principles of SAN design should be considered? (Choose three.)
A. scalability of LAN infrastructure; reduced Ethernet QoS complexity
B. port density and topology requirements; number of ports required now and in the future
C. device performance and oversubscription ratios; determination of what is acceptable and what is unavoidable
D. fault isolation; consolidation while maintaining isolation
E. security management; preferential network security
F. future growth in WAN infrastructure
Correct Answer: BCD
These underlying principles fall i nto five general categories:
■ Port density and topology requirements: Number of ports re quired now and in the
future
■ Device performance and oversubscription ratios:Determination of what is accept able
and what is unavoidable
■ Traffic management: Preferential ro uting or resource allocation
■ Fault isolation: Consolidation while maintaining isolation
■ Control plane scalability :Reduced routing complexity
