medium📝 Predict Output Q4 of 15
Step-by-Step Solution
Solution:
Step 1: Calculate total shards per index
Total shards = primary shards + replicas per primary = 4 + (4 * 1) = 8 shards.Step 2: Consider cluster nodes and shard allocation
Each shard and its replica are allocated on different nodes, but total shards remain 8 for the index.Final Answer:
8 -> Option AQuick Check:
Total shards = primary + replicas = 8 [OK]
Quick Trick: Total shards = primary shards x (1 + replicas) [OK]
Common Mistakes:
MISTAKES- Counting only primary shards
- Adding nodes to shard count incorrectly
- Confusing replicas with extra shards
