Answer #1

C is correct. Source port numbers from a requesting machine are dynamic and must not be from the well-known port range 0–1023.

A, B, and D are incorrect. All these answers are from the well-known port range, which cannot be used here.

How do you think TCP would handle the problem if an acknowledgment were lost, so that the sender retrans- mitted the unacknowledged TCP seg- ment, therefore causing the receiving transport process to receive the same segment twice? 2-2. a) Compute the minimum number of TCP segments required to open a con- nection, send an HTTP request and response message, and close the con- nection. Justify this number by creating a table showing each message and...
