Which two components are included in a transport header? (Choose two.)

The transport layer in the OSI model is responsible for end-to-end communication and error

recovery. In a transport header, such as TCP or UDP, the key components include the source port

number and the destination port number. These port numbers are used to identify sending and

receiving applications. The source port number indicates the port of the sending application, and the

destination port number refers to the port of the receiving application. MAC addresses, on the other

hand, are part of the data link layer (Layer 2) and would be included in an Ethernet header, not a

transport header.
