Exam JN0-104 topic 1 question 29 discussion

flow control is only a property for TCP, not for UDP, so it is not generally a function of the transport layer (L4)

Correct Answer is C and D

D is obvious. Between A and C, I would say C wins, because Data Integrity is not the main function of Transport layer. Flow Control is.

please disregard my previous vote, I meant A-C, for the previous comment nothing changes.

It is A and D

Needs to be A and D Data integrity Segmentation Question asks transport layer in general. TCP does flow control, but UDP does not. However data integrity is a property for both TCP and UDP

CD: Transport The fourth layer of the OSI model ensures complete and reliable delivery of data packets. The transport layer provides mechanisms such as error control, flow control, and congestion control to keep track of the data packets, check for errors and duplication, and resend the information that fails delivery

Shouldn't this be A and D ? Both TCP and UDP have a checksum field in the header. The issue is that both flow control and data integrity can be done both at L2 and at L4. The only difference is that on L2 they are done on a the local LAN, and at L4 they are done end-to-end.

TCP is transport layer, responsible for data integrity
