Check Point Certified Security Administrator (CCSA) R81.20 — Question 19

Fill in the blanks: The Application Layer Firewalls inspect traffic through the _____ layer(s) of the TCP/IP model and up to and including the _____ layer.

Answer options

• A. Upper; Application
• B. Lower; Application
• C. First two; Internet
• D. First two; Transport

Correct answer: B

Explanation

The correct answer is B because Application Layer Firewalls examine traffic at the lower layers of the TCP/IP model, specifically the Network Interface and Internet layers, and extend their inspection up to the Application layer. Options A, C, and D are incorrect as they either misidentify the layers being inspected or do not accurately represent the scope of the firewall's operation.
