Exam E20-920 topic 1 question 16 discussion

Answer : D Explanation: Appliances offer a turnkey infrastructure and unparalleled simplicity for IT transformation. For customers that lack the expertise in house to deploy and manage converged systems, appliances offer a “simple-to-procure, deploy, and manage” option. As with blocks, appliances also are based on a SINGLE personality where a customer can add a single cloud layer on these systems. This next category of Racks is where we start to look at application transformation. Racks come in two flavors: Turn-key cloud or application systems, which in addition to the hardware and hypervisor layers also offer a complete single cloud or application experience out of the factory, built to customer specifications and systems that offer the ability to support multiple personas on top of a common hardware platform. Customers can then add one or more cloud deployment models to deliver applications to fit their business and application needs. These systems provide the flexibility of not only multiple personas, but also the ability to scale storage independently of the compute.
