The systems administrator wishes to implement a hardware-based encryption method that could also be
used to sign code. They can achieve this by:

A.
Utilizing the already present TPM.

B.
Configuring secure application sandboxes.

C.
Enforcing whole disk encryption.

D.
Moving data and applications into the cloud.

Explanation:
Trusted Platform Module (TPM) is a hardware-based encryption solution that is embedded in the
system’s motherboard and is enabled or disable in BIOS. It helps with hash key generation and stores
cryptographic keys, passwords, or certificates.
Incorrect Answers:
B: Sandboxing is the process of isolating a system before installing new applications on it so as to restrict
any potential harm it may cause to production systems.
C: Whole disk encryption can be implemented by either a software-based cryptography solutions or by a
hardware based solution such as a Trusted Platform Module (TPM) or a Hardware Security Module
(HSM).
D:
Moving data and applications to the cloud does not ensure that the data or applications are encrypted
in its new location.
