Which IBM flash System A9000 function enables the division of storage system administration tasks into logical domains?
A . Access-based permissions
B . Storage-based permissions
C . Interface-based permissions

Answer: D

Explanation:

IBM FlashSystem A9000 enables a secure isolation of logical domains of storage

resources among numerous tenants, with the ability to set different QoS levels for each

domain. Multi-tenancy enables the division of storage system administration tasks into

logical domains by using role-based permissions. It also enables rapid deployments while

minimizing the need for extensive planning, tuning, or field upgrades.
