   A company runs a financial application that requires high availability and low latency. The application is transactional and cannot tolerate data loss. The storage team is considering two designs: synchronous replication to a secondary site (higher cost, zero data loss) or asynchronous replication (lower cost, potential data loss). Which design is MOST appropriate?

   • ASynchronous replication to ensure zero data loss
   • BAsynchronous replication with frequent backups
   • CAsynchronous replication to reduce cost
   • DNo replication, relying on backups

   A company runs a video surveillance system that writes continuous high-definition video streams to storage. The system also needs to support occasional playback of recorded footage. The storage team is evaluating whether to use a high-IOPS all-flash array or a high-capacity HDD-based system. Which factor is MOST important in this decision?

   • AThe need for low latency during playback
   • BThe sequential write pattern of the video streams
   • CThe random read pattern of the video streams
   • DThe need for high IOPS for the playback workload
