Exercise 5.1.1
The IEEE 802.1standard concerns with the standards and recommendations in the of architecture and internetworking of local area networks (LANs) and metropolitan area networks (MANs), security, network management, and protocol issues above the Data Link Layer.
Exercise 5.1.2
The original 802.3 standard that defined PoE is IEEE 802.3af. The standard was enhanced in 2009 and give the new standard name 802.3af PoE+.

Exercise 5.1.4
The numeric prefix before BASE in the Ethernet standards defines the transmission speed. The postfix –T implies twisted pair.
Lab 5.2
Exercise 5.2.1
A MAC address must be unique for every NIC produced because switches forward frames based on their destination MAC address and if more than one NIC in the same LAN were to have the same MAC address (including the last 24 bits in the MAC address) then the switches would be confused as to which NIC would get the frame.
