   A company needs to deploy ECS to support a global file-sharing application. Users are located in North America and Europe. The application must provide low-latency access to data in both regions. Which deployment model is most appropriate?

   • AA single ECS cluster in North America with a CDN for Europe.
   • BTwo ECS clusters, one in each region, with bidirectional asynchronous replication.
   • CA single ECS cluster in Europe with a VPN for North American users.
   • DA stretch cluster across both regions with synchronous replication.

   An organization is deploying a single-site ECS cluster. They want to ensure that the cluster can continue to operate if one of the network switches fails. What is the minimum network configuration required?

   • ATwo switches configured in a stack with a single uplink to the core.
   • BA single spine switch with multiple line cards.
   • CA single top-of-rack switch with redundant power supplies.
   • DTwo top-of-rack switches with a redundant link between them.

   A company is deploying ECS across two sites. They want to ensure that data is available in both sites for read access, but they are willing to accept a small amount of data loss in the event of a site failure. Which replication strategy should they use?

   • ALocal replication only
   • BNo replication
   • CAsynchronous replication
   • DSynchronous replication

   A company is deploying ECS across two data centers. They want to use a stretch cluster to provide active-active access. However, they are concerned about the impact of network latency on write performance. What is the best practice to mitigate this concern?

   • AUse a single site for writes and replicate asynchronously to the second site.
   • BUse asynchronous replication between the two sites.
   • CIncrease the replication factor to 4 to reduce latency impact.
   • DPlace the two sites within the same metro area with a low-latency link.

   What is a key characteristic of a single-site ECS deployment?

   • AIt provides data redundancy across multiple geographic locations
   • BIt consists of one or more racks of nodes within a single data center
   • CIt is limited to a single node for simplicity
   • DIt requires a minimum of two sites for data protection
