Question

1. TCP has which of the following characteristics. Choose all true statements.

		three-way hand shake
		none of the above
		regulated send rate
		connection state at the server

2. Consider a subnet with prefix 128.119.40.128/26. Given an example of one IP address (of form xxx.xxx.xxx.xxx) that can be assigned to this network. Suppose an ISP owns the block of addresses of the form 128.119.40.64/26. Suppose it wants to create four subnets from this block, with each block having the same number of IP addresses. What are the prefixes (of form a.b.c.d/x) for the four subnets?

		128.119.40.64/26, 128.119.40.80/26, 128.119.40.96/26, 128.119.40.112/26
		128.119.40.128/28, 128.119.40.144/28, 128.119.40.160/28, 128.119.40.176/28
		128.119.40.64/28, 128.119.40.80/28, 128.119.40.96/28, 128.119.40.112/28
		128.119.40.128/26, 128.119.40.144/26, 128.119.40.160/26, 128.119.40.176/26

3. Which of the following statements are true for Address Resolution Protocol (ARP)? Choose all true statements.

		A host uses ARP to resolve IP addresses for hosts on a different subnet.
		ARP is plug-and-play.
		ARP response packet is sent within a unicast frame.
		ARP query packet is sent within a broadcast frame.

4. Suppose host A is sending a large file to host B over a TCP connection. If the sequence number for a segment of this connection is m, then the sequence number for the subsequent segment will necessarily be m + 1.

True

False

Answer 1

PAGE NO.: DATE: Ans: Three way handshake: To establish a TCP connection, there way handshake is used Regulated Send rate: It is regulated by the an of advertisement corindow of the receiver and acknowledgment bite sind from receives side Connection State: connection state is maintained in YCP to the serven by the care of the eyn and FIN flags and Ack flags. thuis ARP is plag and play - true - JARP table of nodes get automatically build up. ARP response packet is sent canicast - Trece ARP acuery packet cis sent broadcast: Droiy false because secuence number of the subsequent segment will depend on number of 8-bit character in the current segment
