An administrator has just replaced a single-port HBA and needs to complete zoning changes to replace the current alias. The administrator creates the new alias, adds it to the existing zone, and then deletes the old alias. When applying the new configuration, an error states that the original alias is not found and the configuration cannot be applied. Which of the following steps did the administrator miss?
Remove the original alias from the zone before deleting it.

Which of the following is the BEST option to ensure that throughput is maximized on a SAN?
ISLs should be trunked.
An administrator, in preparation for a new server with dual HBAs connected to multiple fabrics, created a new WWN zone to add a new server and storage connections to Fabric A. The administrator then copied the zone in to the zoning configuration for Fabric B and activated it in both fabrics.
