Question 8

Ping utility sends--------- packets to end hosts to test reachability

Answer 1

1. The Time to live prevent a packet for going in infinite loop(by lifespan of packet on a network) in packet forwarding.

2.In TCP connections, RST packets are used to to reset the connection.

3.Protocol contains a number that indicate type of data in payload. The commonly used value are 17 (for UDP) and 6 (for TCP).SO option (B) and (D)

4.Framing us done in Data link layer so Frame exists in Data link layer.

Packet exists at Network layer.

Segmentation done at transport layer so data segments exist at Transport layer of TCP/IP model.

5.A web browser is software application used for accessing information from the world wide web.

7.Source port and destination port are parts of TCP/UDP. SO option (D) is correct.

8.Ping utility sends Data packets to end hosts to test reachability
