CND Network Perimeter Protection Practice Question
Which TWO of the following characteristics accurately differentiate a Next-Generation Firewall (NGFW) from a traditional stateless or stateful inspection firewall? (Choose two)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
NGFWs can identify applications regardless of port numbers using Deep Packet Inspection and heuristic analysis.
NGFWs incorporate advanced capabilities beyond traditional layer 3/4 packet inspection, such as deep application identification (App-ID) and integrated user identity mapping (User-ID).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Traditional firewalls inspect layer 7 payloads while NGFWs are strictly restricted to layer 3 and layer 4 filtering.
Why it's wrong here
False. This statement is backward; traditional firewalls focus on layer 3/4, while NGFWs inspect layer 7.
- ✓
NGFWs can identify applications regardless of port numbers using Deep Packet Inspection and heuristic analysis.
Why this is correct
True. NGFWs use application signatures and heuristics to identify apps running on non-standard ports.
- ✗
NGFWs rely exclusively on static access control lists based strictly on source IP, destination IP, and TCP/UDP ports.
Why it's wrong here
False. Relying exclusively on IP and ports describes traditional packet-filtering firewalls, not NGFWs.
- ✗
Traditional firewalls require external proxy servers to perform SSL/TLS decryption, whereas NGFWs cannot inspect encrypted traffic.
Why it's wrong here
False. Modern NGFWs have built-in capabilities to perform native SSL/TLS decryption and inspection.
- ✓
NGFWs integrate user identity awareness (e.g., Active Directory integration) into firewall access control policies.
Why this is correct
True. NGFWs map IP addresses to usernames, allowing policies based on user identity or group membership.
