What statement describes a characteristic of MAC addresses?

  • They must be globally unique.
  • They are only routable within the private network.
  • They are added as part of a Layer 3 PDU.
  • They have a 32-bit binary value.
    Explanation:Any vendor selling Ethernet devices must register with the IEEE to ensure the vendor is assigned a unique 24-bit code, which becomes the first 24 bits of the MAC address. The last 24 bits of the MAC address are generated per hardware device. This helps to ensure globally unique addresses for each Ethernet device.
