E20351 Storage Attached Network (SAN)SpecialistExam Free Practice Test — 30 Questions

Question 1

Anya, a SAN specialist, is orchestrating a critical migration of a high-volume transactional database cluster to a new Storage Area Network (SAN) fabric. The legacy SAN infrastructure has been plagued by sporadic performance dips, primarily during peak operational hours, which the team has correlated with increased protocol overhead and network congestion. Investigations reveal that the existing Fibre Channel (FC) zoning is excessively permissive, allowing extensive inter-switch traffic and contributing to potential broadcast storms, thereby hindering precise traffic isolation. Additionally, the implementation of Quality of Service (QoS) has been inconsistent, failing to adequately prioritize the database\'s demanding I/O demands over routine backup operations. Considering these challenges, what strategic approach would most effectively enhance fabric stability and optimize performance for the critical database cluster?

Accepted Answer

Implement granular hard zoning, establish distinct QoS profiles based on workload I/O analysis, and conduct continuous performance monitoring to refine traffic management policies.
