Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Application awareness and identification (App-ID)
Why this is correct
NGFWs identify traffic by application regardless of port numbers.
- ✗
Strict restriction to operating exclusively at Layer 2 (Data Link layer)
Why it's wrong here
Firewalls operate at Layers 3 through 7.
- ✗
Inability to inspect encrypted HTTPS traffic under any circumstances
Why it's wrong here
NGFWs support SSL/TLS decryption inspection.
- ✗
Exclusive reliance on static MAC address filtering for access control
Why it's wrong here
MAC filtering is a Layer 2 switch feature, not an NGFW core mechanism.
- ✓
Integrated user identification and policy enforcement (User-ID)
Why this is correct
NGFWs integrate with directory services to apply firewall rules based on user identity.
