200-155 · Question #42

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.)

The correct answer is A. fault isolation, consolidation while maintaining isolation E. short and long term port density and topology requirements. SAN design principles focus on ensuring high availability and efficient resource utilization, hence fault isolation, consolidation with isolation, and planning for port density and topology are crucial considerations.

Why each option

SAN design principles focus on ensuring high availability and efficient resource utilization, hence fault isolation, consolidation with isolation, and planning for port density and topology are crucial considerations.

Afault isolation, consolidation while maintaining isolationCorrect

Fault isolation ensures that a failure in one part of the SAN does not impact other parts, enhancing availability, while consolidation allows multiple servers to share storage resources efficiently without compromising data separation.

Bfuture growth in LAN infrastructure

Future growth in LAN infrastructure is a general networking concern, but SAN design specifically focuses on storage connectivity, not general LAN expansion.

Csecurity management, preferential network security

While security management is important, 'preferential network security' is not a standard, core principle specifically used to describe SAN design; fault isolation and consolidation are more fundamental.

Dscalability of LAN infrastructure, reduced Ethernet QoS complexity

Scalability of LAN infrastructure and reduced Ethernet QoS complexity are general network design aspects; SAN design focuses on storage-specific scalability and performance rather than general LAN QoS complexity.

Eshort and long term port density and topology requirementsCorrect

Considering short and long-term port density and topology requirements is essential for a SAN to ensure sufficient connectivity, plan for future expansion, and maintain optimal performance and manageability.
