   A company is evaluating ECS deployment models. They have a primary data center and a secondary data center that is used only for disaster recovery. They want to minimize cost and complexity while ensuring that data is available in the secondary site if the primary fails. Which deployment model should they choose?

   • ATwo independent clusters with no replication.
   • BA single cluster with nodes in both sites using synchronous replication.
   • CActive-passive with asynchronous replication to the secondary site.
   • DActive-active stretch cluster with synchronous replication.

   A company is designing an ECS solution for a multi-site deployment. They have two data centers 200 km apart. The business requires that writes are acknowledged only after being stored in both sites, and they want automatic failover. What is the primary constraint they must consider?

   • AThe cluster must have an even number of nodes across both sites.
   • BAsynchronous replication is the only option for distances over 100 km.
   • CThe two sites must be in the same cloud provider to enable replication.
   • DThe distance between sites will introduce latency that may make synchronous replication impractical.
