Question
Someone please explain this for me: for N+ certification, I can not use my phone, notes or books (during the test) but I am asked to determine which MAC address is invalid. All are valid to me but I am being told by N+ that C is invalid. How can I tell which are fake and which ones are correct?
A. AA:CE:58:FD:90:08
B. 44:98:3E:F8:33:23
C. 56:AD:BX:89:55:54
D. 94:9E:FE:EE:8C:DF
No correct solution
