20+ practice questions focused on server-hardware-installation-management — one of the most tested topics on the CompTIA Server+ SK0-005 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start server-hardware-installation-management PracticeA server with a RAID 5 array of four disks reports a degraded logical drive. The technician replaces the failed disk and rebuilds the array. After the rebuild completes, the array is still degraded. Which of the following is the most likely cause?
Explanation: In a RAID 5 array, all disks must operate at the same rotational speed (RPM) to maintain synchronized performance and proper rebuild operations. If a replacement disk has a different rotational speed, the RAID controller may refuse to fully integrate it into the array, leaving the logical drive in a degraded state even after the rebuild process appears to complete. This is because the controller expects uniform timing and performance characteristics across all member disks to ensure data integrity and consistent I/O operations.
A server logged the warning shown in the exhibit. Which of the following should the technician check first?
Explanation: Option C is correct because the warning indicates high processor temperature, which is often caused by a failed or inadequate cooling fan for the CPU. Option A is wrong because the thermal paste would not cause a sudden temperature change; it's a more gradual issue. Option B is wrong while power supply issues can cause overheating, the more direct cause is the CPU fan. Option D is wrong because ambient temperature might be a factor but checking the CPU fan is a more immediate and likely cause.
A server has four memory slots on two channels (A and B). Currently, DIMM_A1 and DIMM_A2 are populated with 8 GB DDR4-2666 modules each. To maximize performance and capacity, which memory configuration should be added?
Explanation: To maximize performance and capacity, you should populate all memory channels equally and use identical modules. Adding two 8 GB DDR4-2666 modules to DIMM_B1 and DIMM_B2 will fill both channels (A and B) with two modules each, enabling dual-channel operation and increasing total capacity to 32 GB. Using the same speed (2666) ensures compatibility and optimal performance.
You are a server administrator at a mid-sized company that hosts its own on-premises Exchange server and file server. The infrastructure consists of three racks: Rack A contains the core switches and firewalls, Rack B contains the Exchange server (Dell PowerEdge R740) and the file server (HP ProLiant DL380 Gen10), and Rack C contains backup devices and a tape library. The data center cooling is provided by a raised-floor system with perforated tiles. Recently, the file server has been experiencing random shutdowns during peak usage hours (10 AM to 2 PM). The shutdowns are preceded by system event log warnings indicating that the CPU temperature has exceeded the threshold. The ambient temperature around the rack is 20°C (68°F) as measured by a handheld thermometer. Other servers in Rack B do not exhibit this behavior. The file server is a 2U server with two Xeon processors, 128 GB RAM, and six hot-swap SATA drives. It runs Windows Server 2019. The server has been in service for three years with no prior issues. The data center manager has noted that the perforated tiles are clear of obstructions. You have verified that the fans in the file server are spinning and the internal air filters are clean. Which of the following is the MOST likely cause of the overheating issue?
Explanation: The file server is a 2U server with two Xeon processors and six drives, generating significant heat, and it is the only server in Rack B experiencing shutdowns. The ambient temperature at the rack is a normal 20°C, and the perforated tiles are clear at the surface, but cable blockage below the raised floor can restrict the cold air plenum, starving that specific tile of airflow. This localized airflow deficiency under the file server is the most likely cause of its CPU overheating while other servers remain fine.
A server has been randomly rebooting several times a day with no pattern. The administrator reviews the IPMI System Event Log and finds multiple 'Correctable ECC error' entries for DIMM slot B2. The server memory is configured with 16 DIMMs of the same type and manufacturer, all recently installed. What should the administrator do FIRST to resolve this issue?
Explanation: Correctable ECC errors indicate a failing or marginal memory module. The first step is to replace the DIMM showing errors. Option A is wrong because reseating does not guarantee the errors will stop, and the DIMM is likely faulty. Option C is wrong because while increasing voltage might help with stability, it is not recommended as a first fix and could void warranty. Option D is wrong because disabling ECC removes error correction but does not fix the underlying hardware fault.
