A network design engineer is asked to design a SAN (or a company Which two underlying principles of SAN design should be considered? Choose two.)
A . fault isolation, consolidation while maintaining isolation
B . future growth in LAN infrastructure
C . security management, preferential network security
D . scalability of LAN infrastructure, reduced Ethernet QoS complexity
E . short and long term port density and topology requirements

Answer: AE

Explanation:

Principles of SAN Design

The underlying principles of SAN design are relatively straightforward: plan a network topology that can handle the number of ports necessary now and into the future; design a network topology with a given end-to-end performance and throughput level in mind, taking into account any physical requirements of a design (for example, whether the data center is or will in the future be located on multiple floors of a building or in multiple buildings or locations); and provide the necessary connectivity with remote data centers to handle the business requirements of business continuity and disaster recovery.

These underlying principles fall into five general categories:

• Port density and topology requirements-Number of ports required now and in the future

• Device performance and oversubscription ratios-Determination of what is acceptable and what is unavoidable

• Traffic management-Preferential routing or resource allocation

• Fault isolation-Consolidation while maintaining isolation

• Control plane scalability-Reduced routing complexity
