   A global logistics company is migrating 200 LUNs from a PowerMax 8000 to a PowerMax 2500. The hosts are running a mix of Windows Server and Linux with native multipathing. The migration must be completed over a weekend, and the storage team wants to minimize the administrative effort required to track the migration. What feature of NDM helps reduce the operational burden during this migration?

   • AThe requirement to manually update the host multipathing configuration for each LUN after the migration.
   • BThe ability to run multiple NDM sessions concurrently and monitor them from a single Unisphere dashboard.
   • CThe need to schedule a maintenance window for each group of 50 LUNs to avoid overloading the array.
   • DThe ability to automatically fail over to the target array if the source array experiences a hardware failure.

   A large enterprise is migrating 500 LUNs from a PowerMax 8000 to a PowerMax 2500. The migration must be completed within a 72-hour window, and the storage team has a limited number of staff available to monitor the migration. The team is concerned about the operational burden of tracking 500 individual NDM sessions. What is the most effective way to reduce the monitoring burden?

   • AUse a third-party script to poll the array API and log the status of each session to a file.
   • BAssign one staff member to monitor each group of 50 sessions manually.
   • CUse Unisphere for PowerMax to monitor all NDM sessions from a single dashboard and set up alerts for any session that fails or stalls.
   • DRun all 500 NDM sessions sequentially to make it easier to track each one.

   A university is migrating a research database from a PowerMax 8000 to a PowerMax 2500. The storage team has started the NDM migration, but the copy is progressing slowly because the source array is heavily loaded with other production workloads. The migration must complete within 48 hours, and the team cannot pause the other workloads. What is the most appropriate action to ensure the migration completes on time?

   • ADelete the target LUNs and recreate them with a smaller size to reduce the copy time.
   • BReboot the source array to clear the I/O queue and speed up the copy.
   • CAbort the NDM session and restart it with a higher priority to force the copy to complete faster.
   • DMonitor the NDM session and, if needed, adjust the copy priority or schedule the migration to run during lower-activity periods.
