Certified Network Defender (CND) — Question 98

Which type of firewall consists of three interfaces and allows further subdivision of the systems based on specific security objectives of the organization?

Answer options

• A. Screened subnet
• B. Bastion host
• C. Unscreened subnet
• D. Multi-homed firewall

Correct answer: D

Explanation

The correct answer is D, as a Multi-homed firewall has multiple interfaces that allow it to connect to different networks, facilitating greater control and segmentation. The other options, such as A (Screened subnet) and B (Bastion host), do not provide the same level of interface diversity and segmentation capabilities, while C (Unscreened subnet) lacks any built-in security measures.
