Question: 1 / 400

What is a characteristic of the replication strategy in Cassandra?

It cannot replicate across data centers

It supports multiple data center replication

One of the main strengths of Apache Cassandra is its ability to support multiple data center replication. This characteristic is crucial for applications that require high availability and disaster recovery strategies across geographically distributed locations.

By allowing data to be replicated across different data centers, Cassandra ensures that even if one data center goes down or experiences issues, the data remains accessible from another location. This feature enhances fault tolerance and allows for improved read and write performance, as clients can connect to the nearest data center.

The ability to configure replication specifically for multiple data centers also means that you can tailor the replication factor based on the needs of your application, balancing between data durability and performance. This flexibility is a significant benefit in many distributed system scenarios, making option B the correct answer.
