The correct answer is B. Header pinouts .
According to CompTIA A+ Core 1 220-1201 objectives under Hardware:
Header pinouts on a motherboard are designated connectors for internal components such as USB ports, audio connectors, and front panel buttons/LEDs.
When adding additional internal USB ports, a technician typically connects them to the motherboard’s USB header pinouts. These headers provide the necessary data and power connections to enable USB functionality for front-panel or expansion USB ports.
Why the other options are incorrect:
A. TPM (Trusted Platform Module): Used for hardware-based security functions like encryption, not USB connectivity.
C. M.2 connector: Used primarily for SSDs and other small-form-factor expansion devices, not standard USB ports.
D. Expansion slots: Typically PCIe or PCI slots are used for expansion cards such as GPUs, network cards, or USB controller cards, but not for connecting internal USB headers directly.
