CompTIA loves to use words like "FIRST", "MOST", or "BEST". These change the correct answer completely.

Eliminate the Impossible

Usually, 2 out of 4 answers are technically unrelated. Discard them first to increase your odds.

Scenario-Based Logic

For PBQs, visualize the actual hardware or OS interface. Think like a technician on a service call.

Secure Boot

A security standard developed by members of the PC industry to help make sure that your PC boots using only software that is trusted by the PC manufacturer. Required for Windows 11.

Essential Firmware Settings

Boot Order / Sequence

Determines which device (HDD, USB, PXE) the system attempts to load the OS from first.

Virtualization (VT-x / AMD-V)

Must be enabled in firmware to allow Type 1 and Type 2 hypervisors to run guest operating systems.

Trusted Platform Module (TPM)

Hardware chip for cryptographic keys. Required for BitLocker full-disk encryption and Win 11.

Supervisor vs. User Password

Supervisor: Access to all settings. User: Access to boot OS or limited settings only.

Firmware Troubleshooting & Maintenance

CMOS Battery (CR2032)

If the battery fails, BIOS settings (time, date, boot order) will reset to defaults every time the PC loses power.

Flashing the BIOS

The process of updating firmware. Critical: Do NOT lose power during this process or the motherboard may be "bricked".

Built-in Monitoring

  • CPU Temp42°C
  • Fan Speed1200 RPM
  • Vcore1.25V
  • Clock3.6GHz
