   A small business wants to deploy ECS for a private cloud storage service. They have a limited budget and only one data center. They need to store archival data that is rarely accessed but must be durable. Which deployment approach is most appropriate?

   • AA multi-site deployment with synchronous replication to a second data center.
   • BA single-node ECS appliance with no replication.
   • CA single-site cluster with a minimum of 3 nodes and local replication enabled.
   • DA stretch cluster across two data centers with asynchronous replication.

   An organization is planning an ECS single-site deployment. They want to ensure the cluster can tolerate the failure of any single node without data loss or downtime. What is the minimum number of nodes required, and what additional configuration is necessary?

   • A3 nodes with replication factor 2.
   • B4 nodes with replication factor 1.
   • C5 nodes with replication factor 3.
   • D2 nodes with replication factor 2.

   A company wants to use ECS for active-passive replication between two sites. The passive site should be used only for disaster recovery and not for serving read requests. Which deployment model should they implement?

   • AA single-site cluster with a backup to tape.
   • BA single stretch cluster with synchronous replication.
   • CTwo independent clusters with asynchronous replication from the active to the passive site.
   • DTwo clusters with bidirectional replication and load balancing.

   A company is designing a multi-site ECS deployment with two sites. They need to ensure that if one site becomes unavailable, the other site can continue to serve reads and writes without data loss. They have a low-latency link between the sites. Which deployment model should they use?

   • AA stretch cluster with synchronous replication.
   • BA single-site cluster with a backup to the second site.
   • CTwo independent clusters with asynchronous replication.
   • DTwo independent clusters with bidirectional asynchronous replication and application-level failover.
