   A storage administrator is monitoring a non-disruptive migration and notices that the 'Copy Progress' is at 45% but the 'Copy Rate' is significantly lower than expected. The source volume is a critical production volume with high I/O. What is the most likely cause of the slow copy rate?

   • AThe migration is paused, which stops the copy process entirely.
   • BThe target volume is larger than the source volume, which increases the copy time.
   • CThe source volume is experiencing high production I/O, which is competing with the migration copy for resources.
   • DThe source and target arrays are not connected via a fast enough link.

   A non-disruptive migration of a production volume has reached the 'Copy Complete' state. The storage administrator needs to make the target volume the active volume for the host. What is the next step in the migration process?

   • ADelete the source volume immediately to free up capacity, as the copy is complete and the source is no longer needed.
   • BPause the migration to hold the current state until the administrator is ready to switch over.
   • CResume the migration to ensure the final incremental copy is applied before cutover.
   • DPerform the cutover operation in Unisphere to switch the host's I/O from the source to the target volume.
