You want to reduce storage costs by moving indices to cheaper hardware after 15 days and delete them after 90 days. How should you configure the ILM policy phases?
ASet cold phase min_age to 15d with move action, delete phase min_age to 90d with delete action
BSet warm phase min_age to 15d with delete action, delete phase min_age to 90d with move action
CSet hot phase min_age to 15d with move action, cold phase min_age to 90d with delete action
DSet delete phase min_age to 15d with move action, cold phase min_age to 90d with delete action
Step-by-Step Solution
Solution:
  1. Step 1: Assign move action to cold phase

    Moving indices to cheaper hardware is done in the cold phase with min_age 15 days.
  2. Step 2: Assign delete action to delete phase

    Deleting indices after 90 days is configured in the delete phase with min_age 90 days.
  3. Final Answer:

    Set cold phase min_age to 15d with move action, delete phase min_age to 90d with delete action -> Option A
  4. Quick Check:

    Cold phase moves, delete phase deletes [OK]
Quick Trick: Cold phase moves indices, delete phase removes them [OK]
Common Mistakes:
MISTAKES
  • Mixing delete and move actions in wrong phases
  • Setting delete action in warm phase
  • Confusing phase min_age values
