A customer has a database application that has multiple distributed virtual volumes. They want to ensure that in the event that one of their data centers goes offline, the virtual volumes will all be available to the surviving site.
What VPLEX option should they implement?
A new VPLEX cluster has been configured. However, you are unable to register any host initiators. After verifying that the host has been properly zoned to the VPLEX cluster, you still cannot register them. What is a possible cause?
Refer to the exhibit.

Which two volumes should be used to complete the displayed command?
Do virtual volumes need to be taken off-line prior to upgrading VPLEX software, and why or whynot?
What is the total number of available engines in the smallest VPLEX Metro configuration?
