PROLIANT SERVER FOUNDATION TEST
2026 FINAL SCRIPT FULL SOLUTIONS AND
CORRECT ANSWERS VERIFIED PRACTICE
GRADED A+
⩥ What types of storage media are commonly used in Dell PowerEdge
servers? Answer: HDDs, SSDs, NVMe drives, M.2 devices, and BOSS
modules.
⩥ What does Dell PowerEdge model nomenclature represent (e.g.,
R750, T550)? Answer: Letter shows form factor (R=rack, T=tower,
M=modular); digits indicate generation/tier.
⩥ Why do servers use ECC memory instead of standard memory?
Answer: ECC detects and corrects single-bit memory errors
automatically.
⩥ What component connects drive bays to the server's storage
controller? Answer: The drive backplane.
⩥ What is the difference between SAS and SATA drives in PowerEdge
servers? Answer: SAS is enterprise-grade (dual-port, higher reliability);
SATA is lower-cost and single-port.
,⩥ What is NVMe and why is it used in servers? Answer: PCIe-attached
solid-state storage with very high throughput and low latency.
⩥ What is the function of a PERC controller? Answer: PowerEdge
RAID Controller implements RAID, caching, and drive management.
⩥ What is a BOSS card, and why is it used? Answer: Boot Optimized
Storage System—dual M.2 SSDs for OS boot.
⩥ What does 'hot-swap' mean in server storage? Answer: Drives can be
replaced while the server remains powered on.
⩥ What differentiates 14G, 15G, and 16G Dell servers? Answer: Newer
generations deliver updated CPUs, PCIe versions, memory speeds, and
security features.
⩥ Which internal elements most impact compute performance? Answer:
CPU core count/frequency, memory channels, DIMM speed.
⩥ What affects maximum RAM capacity in a server? Answer: CPU and
motherboard memory channel architecture.
⩥ Why do servers require redundant power supplies? Answer: To
maintain uptime if one PSU fails.
, ⩥ How does airflow typically move inside a Dell rack server? Answer:
Front-to-back.
⩥ What is the purpose of an air shroud? Answer: Directs airflow through
hot components.
⩥ What does the system board integrate? Answer: CPU sockets, memory
channels, PCIe slots, iDRAC/management.
⩥ What is a chassis intrusion sensor? Answer: A switch that triggers
alerts when the chassis is opened.
⩥ What is an HBA (Host Bus Adapter)? Answer: A controller for
connecting storage devices without RAID.
⩥ Why include redundant cooling fans? Answer: Ensures airflow if one
fan fails.
⩥ What enables servers to run 24/7 reliably? Answer: Enterprise
components, ECC, redundancy, thermal control.
⩥ What is scalability in servers? Answer: Ability to expand CPU,
memory, storage, networking.
