   What is the primary purpose of load balancing client traffic across ECS nodes?

   • ATo reduce the number of client connections
   • BTo ensure even distribution of requests and prevent node overload
   • CTo increase the storage capacity of the cluster
   • DTo provide a single point of failure for the cluster

   A healthcare provider is deploying a 4-node ECS cluster to serve medical imaging data. The application clients access the cluster via a single virtual IP (VIP) that load balances across the nodes. The provider requires that if one node fails, the remaining nodes continue to serve all existing client connections without interruption. Which load balancing configuration meets this requirement?

   • AUse a load balancer that supports session persistence and health checks to redistribute connections to healthy nodes.
   • BConfigure the load balancer with active/passive failover where the VIP moves to a standby node on failure.
   • CDeploy the load balancer in an active/active cluster with connection state synchronization between nodes.
   • DConfigure the load balancer to use source IP hashing so that all requests from a client go to the same node.

   A global bank is deploying ECS across two data centers for disaster recovery. Each site has a 4-node cluster. The bank requires that storage replication traffic between sites uses a dedicated WAN link, and that if the WAN link fails, the clusters continue to operate independently. Which network design provides the required redundancy and isolation?

   • AUse a VPN over the internet for replication and do not use a dedicated link.
   • BUse a single WAN link and rely on the storage nodes to replicate asynchronously.
   • CUse a single dedicated WAN link for replication and rely on the storage nodes to buffer data during an outage.
   • DUse two WAN links from different providers with BGP for failover, and place replication traffic on a dedicated VLAN.
