Campus network designs include small networks that use a single LAN switch, up to very large networks with thousands of connections. A hierarchical LAN design includes The access, distribution, and core layers: The access layer provides endpoints and users direct access to the network. The distribution layer aggregates access layers and provides connectivity to services. The core layer provides connectivity between distribution layers for large LAN environments.
Expanding the Network To support a large, medium or small network, the network designer must develop a strategy to enable the network to be available and to scale effectively and easily. One method of implementing redundancy is by installing duplicate equipment and providing failover services for critical devices.
Another method of implementing redundancy is redundant paths. A failure domain is the area of a network that is impacted when a critical device or network service experiences problems. Smaller failure domains reduce the impact of a failure on company productivity.
Link aggregation allows an administrator to increase the amount of bandwidth between devices by creating one logical link made up of several physical links. EtherChannel is a form of link aggregation used in switched networks. Additionally, a wireless router or a wireless access point AP is required for users to connect. The port density of a switch refers to the number of ports available on a single switch.
Fixed configuration switches typically support up to 48 ports on a single device. Modular switches can support very high-port densities through the addition of multiple switch port line cards. Forwarding rates define the processing capabilities of a switch by rating how much data the switch can process per second. Wire speed is the data rate that each Ethernet port on the switch is capable of attaining. Less expensive, lower performing switches can be used at the access layer, and more expensive, higher performing switches can be used at the distribution and core layers, where the forwarding rate has a greater impact on network performance.
Power over Ethernet PoE allows the switch to deliver power to a device over the existing Ethernet cabling. Multilayer switches are characterized by their ability to build a routing table, support a few routing protocols, and forward IP packets at a rate close to that of Layer 2 forwarding.
Router Hardware Routers play a critical role in networking by connecting homes and businesses to the Internet, interconnecting multiple sites within an enterprise network, providing redundant paths, and connecting ISPs on the Internet. They also act as a translator between different media types and protocols.
Routers also come in many form factors. Network administrators in an enterprise environment should be able to support a variety of routers, from a small desktop router to a rack-mounted or blade model.
Managing Devices IOS refers to the package of routing, switching, security, and other internetworking technologies integrated into a single multitasking operating system.
Out-of-band management is used for initial configuration or when a network connection is unavailable. In-band management is used to monitor and make configuration changes to a network device over a network connection. A basic router configuration includes the hostname for identification, passwords for security, assignment of IP addresses to interfaces for connectivity, and basic routing.

It is valid for all types of engineers including entry-level network engineers, network administrators, network support engineers and network specialists. It helps to become familiar with broad range of networking concepts like OSI models, IP addressing, Network security, etc. It is estimated that more than 1 million CCNA certificates have been awarded since it was first launched in It helps candidates to study CCNA fundamentals and prepare for the latest network technologies they are likely to work on.

Вначале он хотел выстрелить Беккеру в голову, но, будучи профессионалом, решил не рисковать. Целясь в торс, он сводил к минимуму возможность промаха в вертикальной и горизонтальной плоскостях.
