Elasticsearch - Index Management

If an index has number_of_shards set to 5 and number_of_replicas set to 1, how many total shards will Elasticsearch manage?

B10

D15

Step-by-Step Solution

Solution:

Step 1: Calculate total shards including replicas
Total shards = primary shards + replicas per primary * number of primary shards = 5 + (1 * 5) = 10.
Step 2: Confirm the calculation
Each of the 5 primary shards has 1 replica, so total shards managed are 10.
Final Answer:
10 -> Option B
Quick Check:
Total shards = primary + replicas * primary [OK]

Quick Trick: Total shards = shards x (1 + replicas) [OK]
