Which of the following MAC addresses cannot be used as the MAC addresses of host network adapters?
Which of the following MAC addresses cannot be used as the MAC addresses of host network adapters?
Option 01-02-03-04-05-06 cannot be used as the MAC address of host network adapters. This is because the least significant bit of the first octet in a MAC address, when set to 1, indicates a multicast address. Host network adapters typically use unicast addresses, which do not have the least significant bit of the first octet set to 1.
CORRETA: (B)
C correct
Option B (01-02-03-04-05-06) starts with 01, which in binary is 0000 0001. The least significant bit of the first octet in a MAC address, when set to 1, indicates a multicast address. Host network adapters typically use unicast addresses, so this MAC address would not typically be used for a host network adapter.
