The exam covers a broad range of fundamentals, including network fundamentals, network access, IP connectivity, IP services, security fundamentals, automation, and programmability. Prerequisites. There are no prerequisites to take the CCNA certification exam.
CCENT certified staff can install, manage and troubleshoot a small enterprise network, including basic network security. The first step towards a CCNA certification must start by having a CCENT. In 2017, Cisco introduced new ICND1 and ICND2 exams (needed for the new CCNA Routing and Switching).
Cisco Networking Academy or NetAcad is an online global educational program product of American Cisco Systems. It started in California in 1997.
Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
Deencapsulation (or de-encapsulation) is the reverse computer-networking process for receiving information; it removes from the protocol data unit (PDU) a previously concatenated header or tailer that an underlying communications layer transmitted.
CCENT qualified individuals have the knowledge and skill to install, manage, maintain and troubleshoot a small enterprise branch network, including network security.

A network socket is a software structure within a network node of a computer network that serves as an endpoint for sending and receiving data across the network. The structure and properties of a socket are defined by an application programming interface (API) for the networking architecture.
The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them.
A routed protocol is used to deliver application traffic. It provides appropriate addressing information in its internet layer or network layer to allow a packet to be forwarded from one network to another. Examples of routed protocols are the Internet Protocol (IP) and Internetwork Packet Exchange (IPX).
Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network.
