Which HP 3PAR StoreServ features help you meet IT improvement goals? (Select two.)

Virtual Copy is a snapshot feature used for point-in-time data recovery and backup, which improves data protection but is not as broad an "IT improvement goal" as efficiency or continuous availability.

Persistence Ports (or Persistent Ports) in HP 3PAR StoreServ ensures that host connections remain active and I/O continues even if a controller node fails or is taken offline for maintenance, significantly improving storage availability and non-disruptive operations, which are key IT improvement goals.

Virtual Domains provide logical partitioning for multi-tenancy or administrative isolation, improving management and security but not directly addressing efficiency or uptime in the same fundamental way as thin provisioning or persistent ports.

Virtual Lock is a Write Once Read Many (WORM) compliance feature designed for data immutability, which addresses regulatory requirements but not general IT improvement goals like operational efficiency or availability.

Thin provisioning allows the allocation of storage capacity only as data is actually written, rather than pre-allocating the full requested amount. This significantly improves storage utilization, reduces power and cooling costs, and defers hardware purchases, directly addressing IT goals for efficiency and cost reduction.
