   Which statement best describes the overall architecture of Dell ECS?

   • AA storage system that requires a dedicated metadata server for every node in the cluster
   • BA centralized NAS appliance that uses a single operating system instance for all file services
   • CA monolithic storage system with a single controller and fixed capacity limits
   • DA distributed, scale-out architecture that pools storage across multiple nodes to provide a single global namespace

   A media company is replacing a legacy NAS that stores video assets. They need a storage system that can scale from 200 TB to multiple petabytes over the next three years without downtime, and they want to avoid forklift upgrades. They also require S3-compatible access for their existing applications. Which architectural characteristic of Dell ECS makes it the best fit for this requirement?

   • AA scale-out architecture where nodes are added to a cluster to increase capacity and performance
   • BA scale-up controller architecture that allows adding disks to existing nodes
   • CA gateway appliance that fronts existing NAS and presents an S3 interface
   • DA monolithic storage array with a single namespace and fixed performance ceiling

   A large enterprise is planning a multi-site Dell ECS deployment for active-active access. They have two data centers in the same region with low latency between them. They need to ensure that data written to one site is immediately available for read from the other site. Which configuration should they use?

   • AA single ECS cluster stretched across both sites
   • BTwo separate ECS clusters with asynchronous geo-replication
   • CTwo separate clusters with manual data copy
   • DOne cluster in one site and a backup appliance in the other

   How does ECS differ from a traditional SAN storage system in terms of data access?

   • AECS uses Fibre Channel for access, while SAN uses Ethernet
   • BECS primarily provides block-level access, while SAN provides file and object access
   • CBoth ECS and SAN provide the same access methods, but ECS uses a different protocol
   • DECS primarily provides object and file access, while SAN provides block-level access
