CCNA - Network Access

In Cisco's CCNA (Cisco Certified Network Associate) certification program, the Network Access domain covers the basic concepts and technologies related to network access control, including VLANs, Ethernet switching, and wireless LANs.

Here's an overview of the key topics covered in the Network Access domain of the CCNA program:

VLANs: This topic covers Virtual Local Area Networks (VLANs), which allow a single physical switch to be divided into multiple logical switches. VLANs can be used to separate traffic based on department, function, or security level, and can help reduce the size of broadcast domains.

Spanning Tree Protocol (STP): This topic covers STP, a protocol used to prevent loops in Ethernet networks. STP elects a root bridge and disables certain links to prevent loops and ensure a single path through the network.

EtherChannel: This topic covers EtherChannel, a technique used to increase the bandwidth and redundancy of links between switches. EtherChannel groups multiple physical links into a single logical link, and can improve network performance and resilience.

Wireless LANs:This topic covers the basic concepts and technologies related to wireless LANs, including wireless standards, frequency bands, and security mechanisms. It also covers the different types of wireless devices, such as access points and wireless clients.

Network Security: This topic covers the basic principles and technologies of network security, including access control lists (ACLs), port security, and device hardening. It also covers the different types of attacks and threats that can affect network security, and how to prevent and mitigate them.

Overall, the Network Access domain is an important part of the CCNA program, as it covers the foundational concepts and technologies of network access control. By mastering these topics, network administrators can ensure that their networks are secure, efficient, and reliable.
