• Question 25:

  What is the main purpose of backup storage?

  A. Hosts production system
  B. Protects important data for quick recovery
  C. Meets regulatory compliance and retains historical data.
  B. Protects important data for quick recovery

  ---

  Explanation

  Backup storage is a type of data storage that is used to create copies of data that can be restored in case of data loss, corruption, or disaster. Backup storage typically has high performance and reliability, and often uses incremental or differential methods to reduce the amount of data that needs to be backed up. Backup storage can be located on- premises or in the cloud

• Question 30:

  How can storage contribute to carbon neutrality?

  A. All-flash storage has become the norm. Compared with mechanical disks, fewer SSDs can save more energy. Taking a data center with .. SSDs reduces power consumption by 2.4 times.
  B. All-flash storage is easier to maintain.
  C. All-flash storage is easier to use.
  D. All-flash storage is more reliable.
  A. All-flash storage has become the norm. Compared with mechanical disks, fewer SSDs can save more energy. Taking a data center with .. SSDs reduces power consumption by 2.4 times.

  ---

  Explanation

  All-flash storage can contribute to carbon neutrality by reducing the energy consumption and carbon footprint of data centers. Compared with mechanical disks, fewer SSDs can provide the same or higher performance and capacity, while saving more energy. According to a report by DEKRA9, taking a data center with 1000 disks as an example, replacing mechanical disks with SSDs reduces power consumption by 2.4 times and carbon emissions by 2.3 times per year1
