What are two features of protocols used within the TCP/IP protocol stack? (Choose two.)

• The Internet Layer IP protocol has built in mechanisms for ensuring the reliable transmission and receipt of data.
• UDP is used when an application must be delivered as quickly as possible and some loss of data can be tolerated.
• TCP and UDP destination port numbers are dynamically generated by the sending device in order to track the responses to requests.
• TCP mechanisms retransmit data when an acknowledgment is not received from the destination system within a set period of time.
• The same Transport Layer source port is used for all of the tabs opened at the same time within a web browser.

Explanation: Application programmers make decisions about which protocols to use to transport the data to and from their applications based on whether the application can tolerate any lost data. Live streaming and voice transmissions can use UDP because if a few data packets are lost, the quality of the video and audio is not seriously impacted. TCP is used when all data must be complete and accurate.
