Question 30
A company is using OpenSearch to store customer orders and product data. They want to ensure that even if a node in the OpenSearch cluster fails, no data is lost, and the search functionality remains operational. Which configuration should they implement to meet these requirements?
-
A
Configure multiple nodes with primary and replica shards.
-
B
Configure multiple nodes with only primary shards.
-
C
Store all data in cold storage for redundancy.
-
D
Use a single node with replica shards enabled.
Reveal correct answer
Correct answer: A
A.
Configuring multiple nodes with primary and replica shards ensures data redundancy and fault tolerance. If one node fails, replica shards on other nodes can handle search requests, maintaining availability and data integrity.
B.
Using only primary shards provides no data redundancy. If a node with primary shards fails, data and search functionality will be affected.
C.
Cold storage is not designed for high-availability search operations and requires reattachment to access the data, making it unsuitable for real-time search needs.
D.
A single node, even with replica shards, does not provide high availability or fault tolerance in case of node failure.
