Choose the correct statements from the following A. In connection oriented…

Answer: The two correct statements are: "In connection oriented service, the destination address is to be specified only during the setup." and "Flooding is a method in which every incoming packet is sent out on every outgoing line except the one by which it arrived."

• Why the destination-address-at-setup statement is correct: Connection-oriented services (for example virtual circuit networks) establish a connection before data transfer. During setup the endpoints and route are determined and subsequent packets use the established connection identifier rather than resending the full destination address each time.

• Why the flooding statement is correct: Flooding is a simple routing strategy in which a node forwards each incoming packet on all outgoing links except the link on which the packet arrived, ensuring broad dissemination.

• Why the packet-sequencing statement is incorrect: The claim that packet sequencing is not guaranteed in connection-oriented service is false. Connection-oriented services typically provide in-order delivery because packets follow the established path or are reassembled in sequence by the transport layer.

• Why the presentation-layer statement is incorrect: The presentation layer is responsible for data representation tasks such as formatting, translation, compression, and encryption. Detection and recovery from transmission errors are functions typically handled by the data link layer (for link-level errors) and the transport layer (for end-to-end error control).
