Which of the following should a technician do FIRST in the BIOS to set up drive encryption?

Options

AEnable eSATA support
BRun built-in diagnostics
CEnable TPM
DEnable virtualization support

Explanation

TPM (Trusted Platform Module) is a dedicated security chip that stores cryptographic keys required for drive encryption technologies such as BitLocker. Without enabling TPM in the BIOS first, the operating system cannot access or use the hardware-level key storage that drive encryption depends on. eSATA support (A) is for external drives and unrelated to encryption. Built-in diagnostics (B) test hardware health, not security. Virtualization support (D) enables running virtual machines, also unrelated to encryption setup.
