Free Palo Alto Networks Cybersecurity-Apprentice Actual Exam Questions - Question 3 Discussion

It’s A because error detection usually happens at the Transport layer in TCP/IP, while the OSI Physical layer deals more with raw bit transmission, not error checking. That difference stands out here.

C, since both Internet and OSI Network layers focus on routing and IP addressing.

It’s C, Internet and Network layers both handle routing and IP tasks clearly.

A/B? A seems off since error detection is usually in Transport for TCP/IP, not Physical for OSI. B feels wrong too because Session usually manages sessions, not encryption—that’s more Presentation layer stuff.

Makes sense that C is the best fit since both layers deal with routing and IP tasks. The other options confuse where certain functions like encryption or error detection sit. C

C The Internet layer handling IP and routing is pretty much the same as OSI’s Network layer, so that matches up well. The other options mix up functions that don’t really belong to those layers.

C sounds right since the TCP/IP Internet layer matches the OSI Network layer for IP addressing and routing. The others don’t line up with what I know about the layers.
