  • C) A graphical shell
  • D) A protocol
See the answer

Answer: B) A shell that listens on a port

The bind shell opens a port on the victim (often blocked by firewalls).

  • C) ConnectPipe
  • D) JoinPipe
See the answer

Answer: B) CreateFile with the pipe path

Use CreateFile("\\.\pipe\PipeName", ...).

Question 16​

What is the client-server model?

  • A) A virus
  • B) A model where the server provides services to clients
  • C) A file
  • D) An email protocol
See the answer

Answer: B) A model where the server provides services to clients

The client requests, the server responds.

Question 17​

Which Python library is used for sockets?

  • A) os
  • B) socket
  • C) network
  • D) tcp
See the answer

Answer: B) socket

import socket allows creating sockets in Python.

Question 18​

Which socket method listens for incoming connections?

  • A) socket.wait()
  • B) socket.listen()
  • C) socket.hear()
  • D) socket.receive()
See the answer

Answer: B) socket.listen()

listen() puts the socket in listening mode.

Question 19​

Which method accepts an incoming connection?

  • A) socket.get()
  • B) socket.accept()
  • C) socket.receive()

  • D) It's optional
See the answer

Answer: B) Sockets transmit bytes, not strings

Encoding (str.encode()) and decoding (bytes.decode()) are necessary.

  • A) A virus
  • B) A mutual block where multiple processes wait indefinitely
  • C) A file
  • D) A protocol
See the answer

Answer: B) A mutual block

How to avoid race conditions?

  • A) Use more RAM
  • B) Use synchronization mechanisms (mutex, semaphores)
  • C) Restart the PC
  • D) Delete files
See the answer

Answer: B) Use synchronization mechanisms

Mutexes, semaphores, and locks prevent access conflicts.
