HP System Configuration & Troubleshooting 3 — Questions and Answers
Question 1: In HP UEFI Setup, enabling 'Virtualization Technology (VTx)' is required for which scenario?
- Running multiple monitors on a single GPU
- Running hypervisors such as VMware or Hyper-V on the workstation (Correct answer)
- Enabling Secure Boot with TPM 2.0
- Configuring RAID 0 on NVMe drives
Correct answer: Running hypervisors such as VMware or Hyper-V on the workstation
VTx (Intel Virtualization Technology) must be enabled in BIOS/UEFI to allow hypervisors to create and manage virtual machines on the host hardware.
Question 2: An HP EliteBook fails to boot and shows a '3F0' error code. What does this indicate?
- Memory failure detected
- No bootable device found / hard drive not detected (Correct answer)
- Fan failure or thermal shutdown
- BIOS corruption detected
Correct answer: No bootable device found / hard drive not detected
HP error code 3F0 indicates the system cannot find a bootable device, typically meaning the hard drive is not detected or the boot order is misconfigured.
Question 3: What is the purpose of the HP Sure Start feature found in HP Elite and Pro series devices?
- Automatically backs up user data to the cloud on startup
- Self-heals the BIOS if corruption or attack is detected (Correct answer)
- Accelerates boot time by pre-loading drivers
- Monitors network traffic for security threats
Correct answer: Self-heals the BIOS if corruption or attack is detected
HP Sure Start continuously monitors the BIOS and automatically restores it from a protected golden copy if tampering or corruption is detected.
Question 4: A technician needs to wipe all data from an HP laptop's SSD before disposal. Which HP tool provides a certified drive erase function?
- HP Support Assistant
- HP PC Hardware Diagnostics UEFI (Correct answer)
- HP Drive Encryption
- HP Connection Manager
Correct answer: HP PC Hardware Diagnostics UEFI
HP PC Hardware Diagnostics UEFI includes a Secure Disk Erase utility that can perform certified data sanitization on the drive independently of the OS.
Question 5: Which setting in HP UEFI controls whether legacy BIOS (CSM) mode is available alongside UEFI boot?
- Fast Boot
- Secure Boot
- Legacy Support / CSM toggle (Correct answer)
- Network Boot (PXE)
Correct answer: Legacy Support / CSM toggle
The CSM (Compatibility Support Module) or Legacy Support toggle in UEFI enables or disables the ability to boot legacy BIOS-based operating systems and devices.
Question 6: An HP workstation emits 5 beeps during POST. According to HP beep codes, this typically indicates a problem with which component?
- Graphics card failure
- Real-Time Clock failure
- Pre-video memory error (Correct answer)
- CPU cache error
Correct answer: Pre-video memory error
On HP systems, 5 beeps during POST typically signal a pre-video memory (RAM) error, indicating the system cannot complete memory initialization.
Question 7: A user installed a second RAM stick in an HP desktop but the system now shows less total RAM than expected. What should the technician verify first?
- Whether the OS is 32-bit, which limits addressable RAM
- That the new RAM is seated in the correct paired DIMM slot for dual-channel configuration (Correct answer)
- That Secure Boot is disabled to allow new hardware
- That the CMOS battery was replaced after installation
Correct answer: That the new RAM is seated in the correct paired DIMM slot for dual-channel configuration
HP desktops require RAM installed in specific paired slots for dual-channel operation; installing in the wrong slot can cause the system to not recognize the module or run incorrectly.
