CompTIA Security+ (SY0-501) — Question 141

A company is developing a new secure technology and requires computers being used for development to be isolated. Which of the following should be implemented to provide the MOST secure environment?

Answer options

• A. A perimeter firewall and IDS
• B. An air gapped computer network
• C. A honeypot residing in a DMZ
• D. An ad hoc network with NAT
• E. A bastion host

Correct answer: B

Explanation

An air gapped computer network (option B) is the most secure solution as it ensures that the development environment is completely isolated from other networks, minimizing the risk of external attacks. The other options, while they provide some security, do not achieve the same level of isolation; for example, a perimeter firewall and IDS (option A) still allows for some connectivity, and a honeypot (option C) is primarily used for monitoring attacks rather than securing development systems.
