   A government agency is deploying a Dell midrange storage array in a two-node cluster for a critical database. The database requires high availability and consistent performance. The agency has a limited budget and cannot afford to over-provision hardware. Which clustering best practice should they follow?

   • AConfigure both nodes with identical hardware and software versions to ensure consistent performance and failover.
   • BUse one node with higher performance and the other with lower performance to save costs.
   • CPlace both nodes in the same rack to simplify cabling and reduce costs.
   • DUse a single node with redundant components instead of a cluster to reduce costs.

   A manufacturing company is planning to upgrade the operating system on its Dell midrange storage array. The array is currently running a version that is two releases behind. The upgrade must be performed with minimal downtime. Which approach aligns with Dell best practices?

   • AUpgrade directly to the latest version in one step to minimize the number of maintenance windows.
   • BReview the release notes and compatibility matrix, then upgrade sequentially through supported versions during a maintenance window.
   • CPerform a non-disruptive upgrade during business hours to avoid after-hours work.
   • DUpgrade only the controller firmware and skip the OS upgrade to reduce complexity.

   A hospital is deploying a Dell midrange storage array to host an electronic health record (EHR) system. The EHR vendor requires a minimum of 50 TB usable capacity and 20,000 IOPS for the database workload. The storage team plans to use RAID 5 (4+1) with 1.8 TB 10K SAS drives. The array supports up to 240 drives. Which configuration best meets the vendor requirements while following Dell best practices for capacity and performance?

   • AConfigure 60 drives as a RAID 10 group to maximize performance, even though it reduces usable capacity.
   • BUse RAID 6 (4+2) with 60 drives in a single group to provide better fault tolerance and capacity.
   • CConfigure 60 drives in a single RAID 5 group, then present the entire LUN to the database server.
   • DCreate multiple RAID 5 groups of 5 drives each, using 60 drives total, and stripe across them to form a larger volume.

   A company is planning to upgrade the OS on its Dell midrange storage array. The array is currently at 90% capacity and hosts a critical database. The upgrade is expected to take several hours. What is the best practice to ensure a successful upgrade?

   • AUpgrade the array during peak hours to ensure the upgrade is completed quickly.
   • BFree up at least 10% capacity before the upgrade to ensure the array has enough space for temporary files.
   • CPerform the upgrade without freeing capacity, as upgrades do not require additional space.
   • DTake a snapshot of the database before the upgrade to protect against data loss.
