Topics Covered in CCNA v3:

Network Fundamentals:

• Understanding network topologies, physical and logical networks, and the OSI model.
• Grasping the basics of IP addressing, including IPv4 and IPv6, subnetting, and VLSM (Variable Length Subnet Masking).
• Understanding the function and configuration of routers and switches in a network.
• Learning about network cabling, wireless networks, and basic concepts of virtualization and cloud computing.

Network Access:

• Configuring and verifying VLANs (Virtual Local Area Networks), trunking, and inter-VLAN routing.
• Understanding the concepts and configuration of Ethernet and wireless networks.
• Implementing and verifying STP (Spanning Tree Protocol) and RSTP (Rapid Spanning Tree Protocol).
• Configuring and managing network devices to control access, including port security, MAC address filtering, and Network Access Control (NAC).

IP Connectivity:

• Understanding and configuring static and dynamic routing protocols, such as OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol).
• Implementing IPv4 and IPv6 routing and verifying route information.
• Understanding routing concepts, such as administrative distance, metrics, and routing tables.
• Configuring default routes and understanding their role in network routing.

IP Services:

• Configuring and verifying NAT (Network Address Translation) to provide internet access to internal devices.
• Implementing and managing DHCP (Dynamic Host Configuration Protocol) for automatic IP address assignment.
• Configuring and verifying NTP (Network Time Protocol) for network device time synchronization.
• Understanding QoS (Quality of Service) concepts and how they affect network traffic.

Security Fundamentals:

• Understanding security concepts, including confidentiality, integrity, and availability (CIA triad).
• Implementing basic security measures on routers and switches, such as access control lists (ACLs) and VPNs (Virtual Private Networks).
• Configuring device hardening features, including password policies and secure management protocols like SSH.
• Understanding security threats, such as DoS attacks, and how to mitigate them.

Automation and Programmability:

• Understanding the role of automation in network management and how it can increase efficiency.
• Learning about network programmability concepts and tools like REST APIs, JSON, and Python scripting.
• Grasping the basics of Software-Defined Networking (SDN) and its impact on network management.
• Exploring Cisco's DNA Center and how it supports network automation and management.
