CompTIA CASP+ (CAS-004) — Question 420

Which of the following is the reason why security engineers often cannot upgrade the security of embedded facility automation systems?

Answer options

• A. They are constrained by available compute.
• B. They lack x86-64 processors.
• C. They lack EEPROM.
• D. They are not logic-bearing devices.

Correct answer: A

Explanation

The correct answer is A because embedded facility automation systems often have limited processing power, which restricts the implementation of advanced security measures. Options B, C, and D are incorrect as the lack of specific processor architectures, EEPROM, or the classification of devices does not primarily impede security upgrades.
