CompTIA Security Plus Mock Test Q831

A hospital IT department wanted to secure its doctor’s tablets. The IT department wants operating system level security and the ability to secure the data from alteration. Which of the following methods would MOST likely work?

A. Cloud storage
B. Removal Media
C. TPM
D. Wiping


Correct Answer: C
Section: Application, Data and Host Security

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:
A: Cloud storage involves using an online storage provider to host data. The operating system would most likely not be installed on cloud storage. Therefore securing removable media
would not provide operating system level security.
B: Removable media includes tape drives, recordable compact disks (CD-Rs), diskettes, memory cards, etc. The operating system would most likely not be installed on removable
media. Therefore securing removable media would not provide operating system level security.
D. Wiping is the process of removing data from a device so that it is no longer recoverable. This is usually done when the device is to be decommissioned or discarded. It does not
provide data security while the device is in use.
