Question

Which of the following statements is true about epsilon?

Options

  • AThere is a specific epsilon for each replicated database unit
  • BIf the node with epsilon is rebooted, epsilon will automatically move to another available node
  • CEpsilon can be moved manually
  • DEpsilon cannot be moved manually

Explanation

Epsilon is a special quorum vote in NetApp ONTAP clusters that can be manually moved between nodes using cluster commands.

Common mistakes.

  • A. Epsilon is a single cluster-wide quorum vote held by exactly one node at a time, not a per-replicated-database-unit construct.
  • B. Epsilon does not automatically relocate when the holding node reboots - the cluster must negotiate quorum without it, and epsilon must be manually reassigned after the node rejoins.
  • D. This is factually incorrect because epsilon can be moved manually using cluster modify commands.
