| Thema 1 | - Networking Foundations: This section of the exam measures the skills of a Network Engineer and covers the basic building blocks of computer networking. It explains different types of networks like local area networks and wireless networks, and introduces lightweight wireless LANs. It describes the layers of communication models like the OSI model and TCP
- IP stack, and explains how data moves across networks. It also discusses the physical cabling used in networks, such as Ethernet and fiber optics. Students will learn about network switching, IP addressing, subnetting, and routing at Layer 3. The section also introduces Cisco¡¯s campus network devices, data center switches, UCS servers, and collaboration devices, describing their roles and functions in the network.

AN access/distribution layers in campuses commonly use Catalyst 9000 Series switches or ISR routers, not high-end core routers.
oE allows the switch to supply power to the IP phone over the same Ethernet cable used for data transmission. This eliminates the need for separate power supplies and simplifies installation.
