   A small business is deploying a PowerEdge T550 server for file storage and print services. The workload is light, with occasional access to documents. The administrator has a limited budget and needs to maximize storage capacity. Which drive type is the most appropriate for this server?

   • ANVMe SSDs, because they provide the fastest access to files.
   • BHigh-capacity SATA HDDs, because they provide the lowest cost per gigabyte for bulk storage.
   • C10K RPM SAS HDDs, because they provide better reliability than SATA drives.
   • DSATA SSDs, because they offer a good balance of performance and capacity.

   A PowerEdge R740 server has a PERC H740P controller with a RAID 5 array of six 1.2TB SAS HDDs. One drive fails, and the administrator replaces it with a new 1.2TB drive. The PERC controller does not automatically start the rebuild. The administrator needs to ensure the array returns to a redundant state as quickly as possible. What should the administrator do first?

   • AReboot the server to force the PERC to detect the new drive and start the rebuild.
   • BCheck the PERC configuration to ensure the new drive is set as a hot spare or manually initiate a rebuild on the new drive.
   • CReplace the new drive with a different model, as the current one is incompatible.
   • DDelete the virtual disk and recreate it with the new drive.

   A data center technician needs to replace a failed hot-swap drive in a PowerEdge R740xd server without powering down the system. The drive is located in a front-accessible bay. What component in the server's architecture is essential for enabling this hot-swap capability and providing the physical connection between the drive and the PERC controller?

   • AThe power supply unit, which provides the necessary power to the drive bay for hot-swap operations.
   • BThe midplane, which provides the electrical and mechanical connection between the drives and the system board.
   • CThe PERC controller, which directly manages the physical connection to each drive bay.
   • DThe backplane, which provides the physical and electrical interface for the drives and supports hot-swap functionality.

   A PowerEdge R750 server has a failed drive in bay 5 of 8. The administrator replaces the drive with a new one while the server is running. The new drive is not automatically recognized by the PERC controller. What is the most likely reason for this issue?

   • AThe new drive is not compatible with the PERC controller.
   • BThe new drive needs to be configured as a hot spare or assigned to the virtual disk in the PERC configuration utility.
   • CThe backplane is faulty and needs to be replaced.
   • DThe server needs to be rebooted for the new drive to be detected.

   When comparing HDDs and SSDs for a Dell PowerEdge server, which statement is accurate?

   • AHDDs are more durable than SSDs because they have no moving parts
   • BSSDs are always lower in capacity than HDDs
   • CHDDs offer faster random access times than SSDs
   • DSSDs provide higher performance but typically cost more per gigabyte than HDDs
