Question 1 of 30

A financial services firm has mandated a complete migration of their primary transactional file share from an aging Hitachi NAS appliance to a new, high-performance Hitachi Content Platform (HCP) system. The critical requirement from the client is \"zero downtime\" for all end-users and applications accessing this share during the transition. The client also expects daily detailed reports on migration progress, any encountered anomalies, and a clear timeline for the final cutover, all while emphasizing that no data loss or corruption is acceptable. Considering the client\'s strict operational constraints and the technical complexities involved in replicating active data, what is the most appropriate implementation strategy to propose?

Establish a real-time data replication stream from the source Hitachi NAS to the HCP, conduct comprehensive data validation and performance testing on the replicated data in the HCP environment, and then perform a meticulously planned, rapid cutover with immediate rollback capabilities if any issues arise during the final switch.
Schedule a maintenance window during off-peak hours to perform a full data export from the source NAS, followed by an import to the HCP, and then reconfigure all client connections to the new system, accepting a brief period of read-only access during the export process.
Implement a parallel file system synchronization tool that mirrors changes from the source NAS to the HCP in near real-time, and then instruct users to manually migrate their critical files to the HCP over a two-week period before decommissioning the old NAS.
Initiate a direct, block-level data copy during a weekend maintenance window, followed by a server reboot and DNS changes to redirect traffic to the new HCP system, with a contingency plan to revert to the old NAS if user access issues are reported within 24 hours.
