   A research institute is deploying a Dell midrange storage array for a high-performance computing (HPC) workload. The workload is sequential read-heavy and requires high throughput. The storage team is considering using RAID 5 or RAID 6. Which RAID level is more appropriate for this workload?

   • ARAID 5, because it provides better write performance and higher usable capacity.
   • BRAID 10, because it provides the best performance for all workloads.
   • CRAID 6, because it provides better fault tolerance and is recommended for large drives.
   • DRAID 0, because it provides the highest throughput and capacity.

   In a Dell Midrange storage solution, when is a single-array deployment model most appropriate?

   • AWhen the storage system must support more than 500 TB of usable capacity
   • BWhen the environment requires high availability across multiple sites
   • CWhen the organization needs to isolate test and production workloads on separate hardware
   • DWhen the workload has low capacity and performance requirements and does not need redundancy at the array level

   A company is deploying a Dell midrange storage cluster for a database that requires high availability. The database has a peak IOPS requirement of 50,000. The storage team is considering using a two-node active/active cluster. What is the most important factor to consider when sizing the cluster?

   • AEach node must be capable of handling the full 50,000 IOPS in case of a failover.
   • BThe cluster should be sized for 100,000 IOPS to provide a 2x performance buffer.
   • CThe cluster should be sized for 50,000 IOPS total, with each node handling 25,000 IOPS during normal operation.
   • DEach node should be sized to handle 25,000 IOPS, since the workload is split between them.

   Which factor is most important when determining the number of drives needed for a Dell Midrange storage system's performance capacity?

   • AThe IOPS and throughput requirements of the workload
   • BThe number of servers in the environment
   • CThe physical size of the drive (e.g., 2.5-inch vs. 3.5-inch)
   • DThe amount of available rack space

   A company is deploying a Dell midrange storage cluster for a mission-critical application. The application requires 99.999% availability. The storage team is considering a two-node cluster with synchronous replication between nodes. What is the most important consideration for meeting the availability requirement?

   • APlace both nodes in the same data center to reduce replication latency.
   • BEnsure that the replication link has sufficient bandwidth and low latency to avoid performance impact.
   • CUse asynchronous replication to avoid performance impact and reduce complexity.
   • DConfigure the cluster in active/passive mode to simplify failover.
