What are two functions of the transport layer? (Choose two.)
What are two functions of the transport layer? (Choose two.)
The transport layer in the OSI model is responsible for flow control and segmentation. Flow control ensures that the sender is not overwhelming the receiver by sending data too quickly, which is managed through mechanisms such as windowing. Segmentation involves dividing a large data stream into smaller, manageable packets to be transmitted over the network, which the transport layer then reassembles at the destination. These functions are essential to maintaining efficient and reliable data transfer over the network.
flow control is only a property for TCP, not for UDP, so it is not generally a function of the transport layer (L4)
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
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.
TCP is transport layer, responsible for data integrity
so you mean A its correct
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
It is A and D
please disregard my previous vote, I meant A-C, for the previous comment nothing changes.

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.

Correct Answer is C and D
