Which of the following is a function of a Trusted Platform Module (TPM)?

A Trusted Platform Module (TPM) is a specialized hardware component designed to enhance the security of a computer system by providing various cryptographic functions. One of its primary functions is storing encryption keys securely. This means that sensitive data such as encryption keys can be kept within the TPM, ensuring that they are protected from unauthorized access and tampering. The TPM generates, stores, and manages these keys in a manner that prevents them from being exposed to the CPU, operating system, or any external attacks, thereby safeguarding the integrity of the cryptographic processes.

This secure storage capability is critical for applications such as hardware-based encryption, secure boot processes, and digital rights management, among others. By isolating sensitive cryptographic materials and performing operations on them within the TPM, the risk of exposure during traditional storage and usage scenarios is significantly reduced.

Other choices, while related to security, do not align with the primary functions of a TPM. For example, providing backups for user accounts or managing user access levels is typically handled by other security mechanisms, like user account management systems or directory services. Monitoring system resources falls outside the scope of what a TPM is designed to do, as its focus is on securing cryptographic materials and ensuring trusted computing environments.
