Elasticsearch - Cluster Management

AAny status is fine during heavy indexing

BGreen, because all shards are allocated and data is fully redundant

CRed, because it prioritizes indexing speed over reliability

DYellow, because it allows faster indexing with fewer replicas

Step-by-Step Solution

Solution:

Step 1: Understand cluster health impact on reliability
Green status means all shards, including replicas, are allocated, ensuring data redundancy and fault tolerance.
Step 2: Evaluate indexing under different statuses
Yellow may allow faster indexing but risks data loss; red means data loss risk; only green ensures reliability.
Final Answer:
Green, because all shards are allocated and data is fully redundant -> Option B
Quick Check:
Green status = full reliability during indexing [OK]

Quick Trick: Aim for green status to keep data safe [OK]
