CompTIA Security+ (SY0-501) — Question 698

Which of the following is the primary reason for implementing layered security measures in a cybersecurity architecture?

Answer options

• A. It increases the number of controls required to subvert a system
• B. It decreases the time a CERT has to respond to a security incident.
• C. It alleviates problems associated with EOL equipment replacement.
• D. It allows for bandwidth upgrades to be made without user disruption.

Correct answer: A

Explanation

The correct answer is A because layered security measures are designed to create multiple barriers that an attacker must overcome, thereby increasing the difficulty of subverting a system. Options B, C, and D do not accurately represent the core purpose of layered security, which is primarily focused on enhancing defense rather than response times, equipment issues, or bandwidth management.
