Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

In Cassandra, ____ replication strategy treats the entire cluster as a single data center. It is suitable for a single data center and one rack. This is also called as Rack-Unaware Strategy.

A	Simple strategy
B	Network topology strategy
C	Quorum strategy
D	None of the mentioned

Explanation:

Detailed explanation-1: -This strategy treats the entire cluster as a single data center. Suitable for a single data center and one rack. This is also called as Rack-Unaware Strategy.

Detailed explanation-2: -The consistency level QUORUM means 51% or a majority of replica nodes across all datacenters responds.

Detailed explanation-3: -Two replication strategies are available: SimpleStrategy : Use only for a single datacenter and one rack. If you ever intend more than one datacenter, use the NetworkTopologyStrategy .

Detailed explanation-4: -Cassandra stores data replicas on multiple nodes to ensure reliability and fault tolerance. The replication strategy for each Edge keyspace determines the nodes where replicas are placed. The total number of replicas for a keyspace across a Cassandra cluster is referred to as the keyspace’s replication factor.

Detailed explanation-5: -SimpleStrategy is used when you have just one data center. SimpleStrategy places the first replica on the node selected by the partitioner. After that, remaining replicas are placed in clockwise direction in the Node ring.
