20 questions · 15 min timer · Explanations included · Free

In a multi-data center Cassandra setup, which strategy is most recommended for ensuring low latency reads?

Use a single data center for all read operations.

Use a global quorum consistency level for read operations.

Set up a dedicated read replica data center.

Configure local_quorum consistency level for read operations.

None

Using local_quorum ensures that read operations are served from the local data center, reducing latency by avoiding cross-data center communication.

In a multi-data center Cassandra setup, which factor is crucial for minimizing the impact of network partitions?

Configuring nodes with high disk I/O capacity.

Ensuring consistent and synchronized time across all nodes.

Implementing a robust backup and restore strategy.

Using a high replication factor in all data centers.

None

A high replication factor across data centers ensures that data remains available and consistent even during network partitions, as more replicas are available to serve requests.
