• Question 291:

  Which version of RAID uses between 3 ?32 discs?

  A. RAID 0

  B. RAID 1

  C. RAID 5

  D. RAID 10

  Correct Answer: C

• Question 292:

  An external storage unit that is self-contained and provides shared file-level access is referred to as:

  A. Small Computer System Interface (SCSI).

  B. Storage Area Network (SAN).

  C. Network Attached Storage (NAS).

  D. Direct Attached Storage (DAS).

  Correct Answer: C

  Network-attached storage (NAS) is file-level computer data storage connected to a computer network providing data access to a heterogeneous group of clients. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often manufactured as a computer appliance ?a specialized computer built from the ground up for storing and serving files ?rather than simply a general purpose computer being used for the role.

• Question 293:

  Which file storage system can be used on a Windows Server?

  A. NFS

  B. NTFS

  C. EXT3

  D. FAT16

  Correct Answer: B

• Question 294:

  Which RAID level can consist of two disks and provides redundancy?

  A. RAID 0

  B. RAID 1

  C. RAID 5

  D. RAID 10

  Correct Answer: B

• Question 295:

  What is the default port used by iSCSI?

  A. 8080

  B. 3128

  C. 3260

  D. 9000

  Correct Answer: C

  Internet Small Computing System Interface (iSCSI) is an Internet Protocol (IP) - based storage networking standard for linking data storage facilities. iSCSI allows clients to send SCSI commands over a TCP/IP network using TCP port 3260.

• Question 296:

  What device contains many hard drives and is used by multiple servers as a central storage area?

  A. NAS

  B. SAN

  C. VOL

  D. Dynamic Drive

  Correct Answer: B

  A storage area network (SAN) is an architecture used for disk arrays, tape libraries, and optical jukeboxes to appear as locally attached drives on a server. A SAN always uses some form of RAID and other technology to make the system redundant against drive failure and to offer high performance.

• Question 297:

  What file-level data storage device is accessed for a network and often uses SMB/CIFS?

  A. NAS

  B. SAN

  C. VOL

  D. Dynamic Drive

  Correct Answer: A

  Network attached storage (NAS) is a file-level data storage device connected to a computer network to provide shared drives or folders, usually using SMB/CIFS. NAS devices usually contain multiple drives in a form of RAID for fault tolerance and are managed usually using a web interface.

• Question 298:

  Which type of RAID is striping with parity?

  A. RAID 0

  B. RAID 1

  C. RAID 5

  D. RAID 0+1

  Correct Answer: C

  RAID 5 is similar to striping, except the space equivalent to one of the hard drives is used for parity (error correction) to provide fault tolerance. To increase performance, the error- correction function is spread across all hard drives in the array to avoid having one drive doing all the work in calculating the parity bits.

• Question 299:

  Which type of RAID is known as disk mirroring?

  A. RAID 0

  B. RAID 1

  C. RAID 5

  D. RAID 0+1

  Correct Answer: B

  RAID 1 is another common form of RAID used in networked PCs and servers. RAID 1 is sometimes known as disk mirroring, which copies a disk or partition onto a second hard drive. Specifically, as information is written, it is written to both hard drives simultaneously.

• Question 300:

  Which form of RAID is known as striping?

  A. RAID 0

  B. RAID 1

  C. RAID 5

  D. RAID 0+1

  Correct Answer: A

  RAID 0 stripes data across all drives. With striping, all available hard drives are combined into a single large virtual file system, with the file system's blocks arrayed so that they are spread evenly across all the drives.
