01) Complete the below table by matching each Layer function to the corresponding OSI layer model: [10 Pts] Layer Function OSI Layer Number(s) (1 to 7) Route determination from end-to-end Converting logical into physical symbols Provides access for the end user Reliable process to process message delivery Session multiplexing and data segmentation Medium Access Control Placement of frames on the media Compression, coding and encryption Application identification Addressing devices from end-to-end Flow control Indicating the upper layer protocol 02) Client-A sends 5 TCP segments to Server-B (a secure web server running HTTPS) sizing each 1000 bytes of data using a window of 5000 Bytes size. Server-B replies back with an acknowledgment number after the five segments are received. However, Server-B detected that the 4th segment contains errors. As per the above stated scenario, complete the missing values (next to each question mark) in each of the below related TCP exchange diagrams: [9 Pts] Client-A Secure Web Server-B Source Port Destination Port Source Port Destination Port Page 6 of 8 Sample Exam Client-A Secure Web Server-B Segment Size - 1000 Window size = 5000 1 Sequence number Sequence number 1001 Sequence number ? Sequence number * Segment with error 2 Sequence number Acknowledgement number ? Sequence number
