Question.1.Explain the practices and techniques to consider when
developing a data protection strategy.
Answer:The size of an enterprise determines which practices, processes or technologies are used for
data protection. It is not reasonable to assume that a small business can deploy expensive, high-end
solutions to protect important data. On the other hand, backing up data to tape or disk is certainly
something that any enterprise can do. A large enterprise will have both the resources and the
motivationtouse more advancedtechnology.
The goal is the same no matter what the size or makeup of the company. Data protection strives to

common to find storage networks in enterprise settings, although some vendors do sell networked
storage productsfor consumersandsmall businesses.
Question.5Briefly explain redundant I/O path elements.
Answer:Multipath I/O (MPIO) is a Microsoft framework designed to mitigate the effects of a host bus
adapter (HBA) failure by providing an alternate data path between storage devices and a Windows
operating system. MPIO enables up to 32 alternate paths to add redundancy and load balancing for
Windowsstorage environments.
Pathing is a networking approach used to address the specific needs of storage networks by changing
the way that communicationpathsare managedand
