• ACreate a two-node DynamoDB Accelerator (DAX) cluster. Configure an application to read and
• BCreate a three-node DynamoDB Accelerator (DAX) cluster. Configure an application to read data
• CCreate a three-node DynamoDB Accelerator (DAX) cluster. Configure an application to read data
• DCreate a single-node DynamoD8 Accelerator (DAX) cluster. Configure an application to read data

Explanation

A DAX cluster can be deployed with one or two nodes for development or test workloads. One- and two-node clusters are not fault-tolerant, and we don't recommend using fewer than three nodes for production use. If a one-or two-node cluster encounters software or hardware errors, the cluster can become unavailable or lose cached data.A DAX cluster can be deployed with one or two nodes for development or test workloads.
