After an upgrade to the company's network infrastructure, the IT department wants to ensure that frames are forwarded only to the intended recipient rather than all connected devices. Which device should they prioritize in their setup?

  • Firewall
  • Hub
  • Router
  • Switch
A Switch operates at the data link layer of the OSI model and makes forwarding decisions based on MAC addresses. It forwards frames only to the intended recipient, reducing network congestion and improving network performance.
