- Host A sent a message to Host B. Assume that CRC-4 (x4+x1+1) is employed for the purpose of error checking. The result of a CRC calculation at Host B is 101. Which of the following statements is true? a. The agreed constant derived from CRC-4 is 10101. b. There was no error at all. c. The agreed constant derived from CRC-4 is 10011. d. There was an error on bit 5 of the message received.Please solve it correctly and please provide explanation of your answers. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was corrupted. So the PC immediately sends an acknowledgement segment. Assume that the PC uses Selective Repeat/Reject ARQ. (a) What will be the sequence number of the third TCP handshake signal send from PC to webserver?…Please solve it correctly and please provide explanation of your answers.

(d) What will be the window size of PC A after receiving only the first segment from webserver? (e)…Q1.Suppose a client, say C, has established a TCP connection with a server, say S. After establishing the connection, the sender sends two TCP messages with data back-to-back ( the first TCP message with sequence number 32 and the second TCP message with sequence number 100). a. What is the sequence number chosen by the client? What could be the reason for choosing this value of sequence number?b. What is the data size of first and second TCP data messages?c. Suppose the server receives the first and second TCP messages with data with the difference of 100 milliseconds delay. What could be the ACK number for both the TCP data messages from the server side as per the TCP RFC.Give outcome of the given scenario: It only permits a user send five packets to its destination at once. Before the sender sends the sixth packet, the sender should wait for the first packet's ACK.
- P27. Host A and B are communicating over a TCP connection, and Host B has already received from A all bytes up through byte 126. Suppose Host A then sends two segments to Host B back-to-back. The first and second segments contain 80 and 40 bytes of data, respectively. In the first segment, the sequence number is 127, the source port number is 302, and the destination port number is 80. Host B sends an acknowledgment whenever it receives a segment from Host A. In the second segment sent from Host A to B, what are the sequence number, source port number, and destination port number? If the first segment arrives before the second segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number, the source port number, and the destination port number? If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number? Suppose the two segments sent by A arrive in order at B.…HostA has established a TCP connection with HostB in a remote network. HostA is sending packets to HostB. Assume we have configured TCP, somehow, to ACK every segment (no ACKing every other segment). Assume that the timeout is the same for all packets. HostB's "window size" is 20000 bytes. HostB has already received and acknowledged everything sent by HostA's application up to and including byte #3,490. HostA now sends segments of the same application data stream in order: P: 467 bytes Q: 252 bytes R: 469 bytes Suppose segments P, Q, and R arrive at Host B in order. What is the acknowledgment number on the segment sent in response to segment R? 4,2102. You have written a terminal emulation program which sends and receives individual 8-bit keystrokes. Now you want to add encryption, to provide confidentiality. You decide to make use of AES-256-CFB - that is AES with a 256-bit key, operating in cipher feedback mode. Once a connection is set up, assuming no padding, how many blocks will AES encrypt in order to transmit a line of 32 keystrokes?
- Host A sends the information of size 3000 bytes to Host B using TCP protocol. As long as Host B receives each packet in size 1000 bytes, Host B must acknowledge Host A. We assume the header size in each packet is 40 bytes, the starting sequence number used by Host A is 1000, and the window size of the sender side is 3000 bytes. What is the value of SND.UNA when the first packet is sent out, but not acknowledged? Question 11 options: 1000 2000 1999 0Host A sends the information of size 3000 bytes to Host B using TCP protocol. As long as Host B receives each packet in size 1000 bytes, Host B must acknowledge Host A. We assume the header size in each packet is 40 bytes, the starting sequence number used by Host A is 1000, and the window size of the sender side is 3000 bytes. What is the value of RCV.NXT in Host B when the second packet in Host A is sent out and acknowledged? Question options: 1000 2000 3000 4000A. “Security is different in wireless” Discuss the statement above. The answer needs to take into account all aspects of the debate. Provide example if. Support your answer with reference. B. In IEEE 802.11, open system authentication simply consists of two communications. An authentication is requested by the client, which contains the station ID (typically the MAC address). This is followed by an authentication response from the AP/router containing a success or failure message. An example of when a failure may occur is if the client’s MAC address is explicitly excluded in the AP/router configuration. What are the benefits of this authentication scheme? What are the security vulnerabilities of this authentication scheme?
