What will be the result of this sequence of commands?
DELETE /test_index
POST /test_index/_close
GET /test_index/_settings
AIndex deleted, error on close, error on get settings
BIndex deleted, close ignored, settings returned
CIndex closed successfully, settings returned
DError on DELETE, index remains open, settings returned
Step-by-Step Solution
Solution:
  1. Step 1: Analyze DELETE command

    The DELETE command removes test_index permanently.
  2. Step 2: Analyze POST close command after deletion

    Since the index is deleted, trying to close it causes an error because it no longer exists.
  3. Step 3: Analyze GET settings command

    Getting settings for a deleted index also results in an error as the index is gone.
  4. Final Answer:

    Index deleted, error on close, error on get settings -> Option A
  5. Quick Check:

    Delete removes index, later commands fail [OK]
Quick Trick: Delete first means index gone, next commands fail [OK]
Common Mistakes:
MISTAKES
  • Assuming close works after delete
