Build real CCNA-ready skills by implementing and securing the core services every network depends on. CCNA Networking Fundamentals: Implementing and Securing Core Services takes you from models and addressing through switching, routing, wireless, and essential network services—with a lab-first approach. You’ll design IPv4/IPv6 plans, configure VLANs and trunks, prevent loops with STP, deploy DHCP for IPv4 and DHCPv6, translate addresses with NAT/PAT, and tune single-area OSPFv2/v3 for reliable routing. Along the way, you’ll apply device-hardening best practices, enable secure management with SSH, and verify everything with show commands and packet captures. The course is tool-agnostic: use Cisco Packet Tracer, CML, or GNS3 to follow a consistent base topology you’ll enhance as you progress. Clear verification workflows ensure you can prove what you’ve built works—end to end. Whether you’re preparing for CCNA or leveling up your job-ready skills, this course focuses on connectivity, performance, and security fundamentals you can apply on day one. Expect concise theory, guided labs, knowledge checks, and practical troubleshooting techniques to build confidence for the exam and the real world.

            <p>Modern networks must deliver reliable connectivity, predictable performance, and built-in security from the ground up. CCNA Networking Fundamentals: Implementing and Securing Core Services is designed to build those capabilities through a lab-first approach that maps directly to CCNA exam objectives. You will progress from foundational models and frame/packet behavior to practical IPv4/IPv6 addressing and neighbor discovery, then into switching, routing, and the core services that make enterprise networks operate at scale. Along the way, the course emphasizes verification, troubleshooting, and hardening so you not only configure a feature, but also prove it works and secure it against common threats.</p>

<p>To ensure you can practice every concept, the course begins with a guided lab setup using Cisco Packet Tracer, CML, or GNS3, and introduces the base topology reused throughout. You will learn to back up device configurations, capture packets to validate behavior, and follow a structured study plan with periodic knowledge checks. Network foundations cover OSI vs. TCP/IP, Ethernet, ARP/ND, and IP forwarding logic. Addressing modules focus on classless IPv4, VLSM, summarization, subnet calculations (including wildcard masks for ACLs/OSPF), and IPv6 design with SLAAC, DHCPv6, RA flags, and dual-stack considerations.</p>

<p>Core switching topics include MAC learning and aging, VLANs and 802.1Q trunks, native VLAN security, and inter-VLAN routing via SVIs or router-on-a-stick. You will design stable Layer 2 topologies using STP/RSTP, apply controls like PortFast, BPDU Guard/Filter, and Root Guard, and verify results with essential show commands. A dedicated wireless module explains APs, WLCs, SSIDs/WLANs, WPA2/WPA3-PSK, 802.1X at a high level, and practical channel planning to reduce interference and improve roaming.</p>

<p>On the routing and services front, you will implement static routes, default and floating statics, and single-area OSPFv2/v3 while understanding LSAs, DR/BDR behavior, and cost metrics. Services modules take you through DHCP for IPv4 and DHCPv6 (server/relay/client roles, exclusions, reservations, options, RA flags), NAT at the edge (static, dynamic, PAT, inside/outside roles), and DNS resolution flows including caching, split-horizon design, and name-related troubleshooting. Security and device hardening round out the core with standard/extended ACL placement, secure management via SSH, users, banners, and an AAA overview, plus logging with syslog levels, NTP time synchronization, and configuration backups.</p>

<p>The capstone focus is verification and troubleshooting. You will practice a layered workflow—from physical to application—using show and safely scoped debug commands, ping, and traceroute, supported by targeted packet captures to confirm DHCP leases, NAT translations, OSPF adjacencies, and STP stability. Reliability and performance are addressed with redundant links, first-hop gateway concepts, OSPF tuning (costs and passive interfaces), and a high-level view of QoS for congestion recognition. Each section includes quizzes to reinforce mastery: addressing and subnetting, switching and STP, OSPF and static routing, DHCP/NAT/DNS, and wireless/security. By the end, you will be able to design small to medium IP plans, implement switching and routing, deploy and secure core services, and confidently verify that your network performs as intended.</p>
