Question

A Database Specialist is troubleshooting complaints from an application's users who are experiencing performance issues when saving data in an Amazon ElastiCache for Redis cluster with cluster mode disabled. The Database Specialist finds that the performance issues are occurring during the cluster's backup window. The cluster runs in a replication group containing three nodes. Memory on the nodes is fully utilized. Organizational policies prohibit the Database Specialist from changing the backup window time. How could the Database Specialist address the performance concern? (Select TWO.)

Options

  • AAdd an additional node to the cluster in the same Availability Zone as the primary.
  • BConfigure the backup job to take a snapshot of a read replica.
  • CIncrease the local instance storage size for the cluster nodes.
  • DIncrease the reserved-memory-percent parameter value.
  • EConfigure the backup process to flush the cache before taking the backup.
