CompTIA Network+ (N10-007) — Question 304

Which of the following would a company place at the edge of its network if it wants to view and control which Internet applications are being used?

Answer options

• A. VPN concentrator
• B. NGFW
• C. IDS/IPS
• D. Proxy server

Correct answer: B

Explanation

The correct answer is B, NGFW (Next-Generation Firewall), as it provides advanced capabilities to inspect and control application traffic. While a VPN concentrator (A) is used for secure remote access and an IDS/IPS (C) detects and prevents intrusions, they do not specifically focus on application control like a NGFW. A Proxy server (D) can manage application traffic but does not offer the same level of integrated security features as a NGFW.
