Check Point Certified Security Administrator (CCSA) R80 — Question 279

How many layers make up the TCP/IP model?

Answer options

• A. 2
• B. 7
• C. 6
• D. 4

Correct answer: D

Explanation

The TCP/IP model consists of 4 layers: Application, Transport, Internet, and Network Interface. The other options (2, 6, and 7) do not correctly represent the number of layers in this model, as they are associated with different networking models or misunderstandings of the TCP/IP framework.
