 **What is considered as storage?** - Any medium data can be written to and retrieved from.  **Name three examples of long-term storage.** - USB memory sticks, CDs/DVDs, and hard disk drives (HDDs).  **What type of storage uses flash memory and has no moving parts?** - Solid state drives (SSD).  **What are the four categories of storage access methods?** - Local storage, Direct-attached storage (DAS), Network-attached storage (NAS), and Storage area network (SAN).  **What is the disadvantage of local storage?** - Only the system where it's installed has direct access to the storage medium.  **What is a DAS device?** - Direct-attached storage; it can refer to HDDs in an enclosure with its own power supply.  **What is Network-Attached Storage (NAS) typically used for?** - File sharing through standard network protocols.  **Name two common network technologies used in SANs.** - Fibre Channel and iSCSI.  **What are physical disk properties?** - Disk capacity, physical speed, and the interface for attaching a disk to the system.  **What does formatting a disk do?** - Prepares a disk with a file system used to organize and store files.  **What is the role of a partition in disk storage?** - It is a logical unit of storage that can be formatted with a file system.  **What is the difference between a boot volume and a system volume?** - Boot volume contains the \\Windows folder, while the system volume has files needed to load the Windows OS.  **What is the capacity limit of Master Boot Record (MBR) partitions?** - 2 TB.  **Which partitioning method supports up to 18 exabytes?** - GUID Partitioning Table (GPT).  **What is a simple volume?** - A volume that resides on a single disk, either basic or dynamic.  **How does a mirrored volume (RAID 1) provide fault tolerance?** - It duplicates data on two disks so if one fails, the other retains the data.  **What is the main purpose of RAID 5?** - Uses disk striping with parity for data recovery in case of a disk failure.  **Which file system is dominant on Windows Servers?** - NTFS (New Technology File System).  **What are the three file systems supported by Windows Server 2012/R2?** - FAT, NTFS, and ReFS.  **What is the limitation of FAT32 regarding file size?** - It supports files up to 4 GB in size.  **What is ReFS primarily used for?** - Large file-sharing applications with Storage Spaces.  **Can ReFS be used to boot Windows?** - No, Windows cannot be booted from an ReFS volume.  **What is the main feature of Storage Spaces in Windows Server 2012?** - It provides flexible provisioning of virtual storage using storage pools.  **What is a VHD file used for in Hyper-V?** - It is the format for virtual disks in virtual machines.  **What is the benefit of using thin provisioning in Storage Spaces?** - It allows large volumes to be provisioned while using only the needed physical storage.  **What does JBOD stand for?** - Just a Bunch of Disks.  **What is a mirrored space in Storage Spaces?** - A storage layout where data is mirrored across two or more disks for redundancy.  **Which storage layout in Storage Spaces is similar to RAID 5?** - Parity space.  **Why is it recommended to install Windows on a separate disk from data?** - To improve performance and organization, especially when using SSDs.  **What is the role of a backplane in storage systems?** - It is a connection system that uses a printed circuit board instead of cables to carry signals.
