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 motivation to use more advanced technology.

The goal is the same no matter what the size or makeup of the company. Data protection strives to minimize business losses due to the lack of verifiable data

It's most common to find storage networks in enterprise settings, although some vendors do sell networked storage products for consumers and small 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 Windows storage environments.

Pathing is a networking approach used to address the specific needs of storage networks by changing the way that communication paths are managed and

Question.6 Describe file system hierarchy and parsing the file system.
