Question $7$

$(7\mathrm{.}1)$ In a client$/$server system, what is the purpose of a timeout setting on a socket connection?

$-$A$.$ To limit the amount of time a client can remain connected to the server.

B$.$ To close a socket if there is no activity for a specified period of time.

C$.$ To delay the processing of cllent requests for a set amount of time.

D$.$ To speed up the communication between client and server.

$(7\mathrm{.}2)$ What is the primary function of a server's run$()$ method in a multithreaded server

application?

A$.$ To establish the initial socket connection with clients.

B$.$ To handle the communication and processing of each client request in a separate thread.

C$.$ To close the connection after the communication is complete.

D$.$ To determine which clients are allowed to connect to the server.

$(7\mathrm{.}3)$ In socket programming, what happens when a server calls accept$()?$

A$.$ The server closes all previous connections and waits for a new connection.

B$.$ The server waits for a client to request a connection and returns a connected socket.

C$.$ The server sends a request for a connection to the client.

D$.$ The server terminates any idle connections to improve performance.

$(7\mathrm{.}4)$ In a client$/$server system, what is the purpose of the input and output streams associated

with a socket?

A$.$ To provide a channel for communication between the client and server.

B$.$ To store data temporarily before sending it to the server.

C$.$ To close the socket connection once communication is complete.

D$.$ To check for errors in the data being transmitted.

$(7\mathrm{.}5)$ Why should socket connections be closed after communication is complete?

A$.$ To free up system resources and avold potential memory leaks.

B$.$ To allow the client to reopen the connection later without issues.

C$.$ To prevent the server from crashing due to too many open connections.

D$.$ To ensure that the data sent is properly saved to the disk.

$(7\mathrm{.}6)$ What can happen if a socket connection remains open for too long without activity?

A$.$ The server may disconnect the client automatically.

B$.$ The socket will automatically restart the communication.

C$.$ The server will prioritize other client connections over this one.

D$.$ The client will be forced to reconnect to the server.

$(7\mathrm{.}7)$ Which of the following is a key difference between client and server roles in socket

communication?

A$.$ The client initiates the connection, while the server listens for incoming requests.

B$.$ The server initiates the connection, while the client waits for responses.

C$.$ The client processes data, while the server only stores the data.

D$.$ The server sends all requests, while the client receives them passively.

$(7\mathrm{.}8)$ Which of the following best describes the concept of blocking in socket communication?

A$.$ A thread waits for an event $($such as a client request$)$ before proceeding.

B$.$ A thread continues to execute, even if there is no client connection.

C$.$ A thread sends data to multiple clients simultaneously.

D$.$ A thread terminates if no clients are connected.

$(7\mathrm{.}9)$ In a socket$-$based system, what could happen if a thread does not handle exceptions

properly?

A$.$ The server may continue to run without any issues.

B$.$ The thread may crash, leaving the server in an unstable state.

C$.$ The thread will automatically restart the communication process.

D$.$ The server will automatically close all open connections.

$(7\mathrm{.}10)$ What should happen if a client attempts to connect to a server that is not currently

running?

A$.$ The client waits indefinitely until the server starts.
