Questions and Answers

What happens when two devices on a shared network segment send packets simultaneously?

  • The packets are prioritized based on IP addresses
  • The packets collide and must be sent again (correct)
  • The packets merge into one and reach the destination twice as fast
  • The packets are discarded if they are not encrypted

    • In which type of network device do all ports belong to the same collision domain?

  • Router
  • Bridge
  • Switch
  • Hub (correct)

    • How does a bridge, switch, or router differ from a hub in terms of collision domains?

  • They create virtual collision domains
  • There are no collision domains in these devices
  • All ports share the same collision domain
  • Each port is in a separate collision domain (correct)

    • What is the impact of multiple devices being in the same collision domain on network efficiency?
