EMC Proven Professional – PowerProtect Specialist — Question 7

Which EMC Avamar function provides fault tolerance across data nodes?

Answer options

• A. RAIN
• B. RAID
• C. Checkpoints
• D. Replication

Correct answer: A

Explanation

RAIN (Redundant Array of Independent Nodes) is specifically designed to provide fault tolerance in EMC Avamar by ensuring that data remains accessible even if one or more nodes fail. RAID, while it offers redundancy for storage disks, does not apply at the data node level. Checkpoints are used for recovery purposes but do not provide node fault tolerance, and Replication is more about data duplication rather than fault tolerance across nodes.
