   A financial trading firm uses Dell Metro Node to provide low-latency access to a database. The storage administrator is considering enabling write caching on the distributed device to improve performance. What is the primary risk associated with write caching in a synchronous replication environment?

   • AThe need to disable read caching
   • BIncreased latency because writes must be cached before being sent
   • CData loss if the cache is not flushed before a director failure
   • DIncompatibility with synchronous replication

   A university runs a research application that generates a high volume of read requests to the same dataset. The storage administrator wants to improve read performance without increasing the number of backend storage arrays. Which distributed device feature can help achieve this?

   • ASynchronous replication of the dataset to a second array
   • BRead caching on the Metro Node directors
   • CConfiguring the array to use a larger stripe size
   • DIncreasing the number of virtual volumes

   In Dell Metro Node, what is the primary role of a distributed device?

   • ATo provide a single logical storage volume that can be accessed from multiple locations
   • BTo connect a host to a single storage array over Fibre Channel
   • CTo provide a backup and recovery solution for virtual machines
   • DTo replicate data asynchronously between two geographically separated storage arrays

   A hospital is deploying Dell Metro Node to provide continuous availability for its electronic health record (EHR) system across two data centers. The storage team must ensure that writes acknowledged to the application are immediately visible to reads from either site, even if one site becomes unavailable. Which distributed device feature is essential to meet this requirement?

   • AAutomatic failover of the virtual IP address
   • BSynchronous replication between the two sites
   • CLocal caching on each Metro Node director
   • DAsynchronous replication with periodic snapshots
