Answer:
Explanation:
From the given information;
We will like you to understand that the source port numbers and destination port number can be any number. For that reason, the ones being used here will just be examples.
NOTE:
That the destination port numbers sent from A to S and B to S are the same in their segments.
That the destination port numbers sent from S to A and S to B are the same in their segments.
From A to S, the segment sent possibly could have the source port number 467 and destination port number as 23(Telnet)
From B to S, the segment sent possibly could have the source port number 513 and destination port number as 23(Telnet).
From S to A, the segment sent possibly could have the source port number as 23(Telnet) and destination port number as 467.
From S to B, the segment sent possibly could have the source port number as 23(Telnet) and destination port number as 513.
Yes, it is possible. This is because the inclusion of IP in the segments is to recognize the host.
No, the source ports will be different. Because source port number from A to S can't be the same from B to S at the time they are in the same host.

Answer:
Interoperability is the ability of or degree to which two or more systems usefully exchange information via interfaces in particular context. Interoperability can be defined in two ways which includes the ability to exchange data (syntactic interoperability) and also the ability to correctly interpret the data being exchanged (semantic interoperability).
If two systems failed to exchange information properly, it means they are not clear to interpret and not easy to communicate and get proper information from each other and that might result in a failed communication which is in turn result in security flaw.
Other quality attributes strongly related (at least potentially) to interoperability is Application Programming Interface (API)
API is a software intermediary that allows two applications to communicate to each other and are necessary for systems interoperability.
