Step-by-Step Solution
Solution:
Step 1: Multiply shard count by shard size
4 shards * 25GB each = 100GB total data size.Step 2: Confirm no replicas included
Replicas do not add to primary data size, so total is 100GB.Final Answer:
100GB -> Option CQuick Check:
Total size = shards * shard size = 100GB [OK]
Quick Trick: Total size = number of shards x shard size [OK]
Common Mistakes:
MISTAKES- Adding replica sizes to total primary data size
- Multiplying shard size by wrong shard count
- Confusing shard size with total index size
