• Question 85:

  Grid storage employs the combination of large scale serial distributed storage to provide even distribution of storage across all nodes.

  A. TRUE
  B. FALSE
  B. FALSE

  Explanation

• Question 86:

  Which of the following statements correctly describe the improvements of SAS technology compared to SCSI? Select All that Apply.

  A. Lower cost than SCSI
  B. Full duplex transmission of data.
  C. Half duplex transmission of data
  D. Higher throughput.
  B. Full duplex transmission of data.
  D. Higher throughput.

  ---

  Explanation

  SAS technology offers full duplex transmission of data and higher throughput than SCSI, which makes it more cost-effective and efficient. SAS technology does not offer half duplex transmission of data.

• Question 87:

  What is the function of hot spare in storage?

  A. Additional space for usage when storage resource is low
  B. Used as cache to increase the performance of disks.
  C. Spare disk space for storing metadata
  D. Spare disk space used for disk data reconstruction when disks are faulty.
  D. Spare disk space used for disk data reconstruction when disks are faulty.

  ---

  Explanation

  In storage, a hot spare is a spare disk that is pre-configured and ready to be used to rebuild data in the event of a disk failure in a RAID array. When a disk failure occurs in a RAID array, the data that was stored on the failed disk is rebuilt using the data from the remaining disks and the hot spare. The rebuild process is done automatically by the RAID controller, and it is done in a way that does not disrupt the normal operation of the RAID array. The hot spare disk is usually kept in a powered-on and ready state, so that it can be used immediately in case of a disk failure. It is also known as "hot spare disk" or "hot spare drive".

• Question 88:

  The following describes RAID 10, which are correct? (Multiple choice)

  A. RAID 10 is used in scenarios with high requirements for speed and fault tolerance
  B. RAID 10 requires at least 4 member disks
  C. In RAID 10, if two member disks in a subgroup fail, the data is read normally
  D. In RAID 10, the data is first mirrored and then striped
  A. RAID 10 is used in scenarios with high requirements for speed and fault tolerance
  B. RAID 10 requires at least 4 member disks
  D. In RAID 10, the data is first mirrored and then striped

  A. TRUE
  B. FALSE
  A. TRUE

  Explanation

• Question 90:

  Which of the following statements about the differences between DAS and SAN is incorrect?

  A. SAN uses the Fibre Channel or iSCSI protocol and therefore offers better scalability.
  B. DAS and SAN are both external storage and can achieve storage resource sharing easily.
  C. DAS applies to small and medium LANs that have general storage capacity requirements and only a small number of servers.
  D. SAN applies to mid-range and high-end storage application environments such as key databases, centralized storage, mass storage, backup, and disaster recovery.
  B. DAS and SAN are both external storage and can achieve storage resource sharing easily.
