New Cisco CCNA (200-301) Volume 1: The Complete Course

Understand the OSI seven-layer model and the TCP/IP suite, and compare them with the Cisco three-layer design, including encapsulation, segmentation, and the roles of core, distribution, and access layers.

Explore tcp/ip headers, focusing on source and destination ports and the well-known, registered, and ephemeral port ranges, and understand how this enables multiplexing for client–server applications.

Learn how DNS resolves domain names to IP addresses via forward and reverse lookup zones and A records, and why URI terminology replaces URL for HTTP and HTTPS.

Explore the fundamentals of ethernet lan, cabling standards, and devices shaping small office home office and enterprise networks, including switches, routers, patch panels, wireless 802.11ac, ip phones, and ip printers.

Build a reliable local area network with UTP cabling by selecting shielded versus unshielded twisted pair, applying 568 color codes and CAT standards, and testing for termination and interference prevention.

Explore building a LAN with fiber cabling, comparing single-mode and multi-mode options, and the color-coding standard ta-598-c, plus essential fiber tools.

Explore Ethernet frames: mac addresses, preamble, dest/source macs, length/type, payload up to 1500 bytes, and frame check sequence, plus how switches and hubs shape collision and broadcast domains.

Learn the fundamentals of wide area networks, frame relay and leased lines, data link connection identifiers, permanent virtual circuits and subinterfaces, and how demarcation points and providers shape wan connectivity.

Learn how routing moves packets across a network using layer 3 addresses and arp, and how routing tables combine connected and dynamic routes with rip, ospf, and bgp.

Configure DNS hostnames, set up static host tables, and point routers to a DNS server to resolve names to IP addresses, and learn FQDN and lookup concepts.

Access the switch CLI via console cable, telnet, SSH, USB, or browser; configure hostname, domain name, local user, and SSH crypto keys for secure lab access.

Explore how LAN switches learn MAC addresses and forward frames across main and intermediate distribution facilities, data centers, and wiring closets, with spanning tree and redundancy concepts.

Learn how switches dynamically build and use mac address tables to forward frames in a hands-on lab. Understand ports, interface and switch mac addresses, arp, and basic spanning tree behavior.

Master housekeeping tasks on Cisco switches, including viewing the MAC address table and aging time. Configure aging from 10 seconds to 1,000,000 seconds and set up local users and AAA.

This lecture guides configuring a Cisco router with correct IP settings, DNS, and domain name, enabling passwords and SSH, generating RSA keys, and implementing radius-based triple-authentication with local fallbacks.

Configure IPv4 on layer-2 switches by setting a management IP, enabling routing for inter-VLAN access, and using trunks with subinterfaces; ensure proper management VLAN and default gateway for remote access.

Explore how VLANs segment broadcast domains on switches, improving efficiency and security by localizing resources, applying ACLs, and reducing network noise through logical grouping by function.

Learn to configure VLANs in a Cisco CCNA lab: create VLAN 10 and 20, set trunk and access ports, apply a BGP domain password, and verify inter-VLAN connectivity.

Learn to configure voice VLANs on Cisco switches by splitting a port into data and voice, using a dedicated voice VLAN and DHCP option 150 with call manager.

Compare STP and RSTP, and understand how rapid spanning tree speeds convergence. Learn how blocking redundant paths prevents broadcast storms and MAC address table instability in modern networks.

Explore how spanning tree elects the root bridge using priority and MAC address, blocks ports to prevent loops, and configures primary and secondary roots in rapid spanning tree.

Explore how EtherChannel aggregates multiple physical links into a single logical channel to increase bandwidth and provide fault tolerance between switches, using lagp and pagp.

During the EtherChannel lab, configure a port-channel on switches, set trunk mode, form channel group 1, and verify active lag and redundancy with multiple links.

Learn the basics of IPv4: 32-bit addresses in four octets using dotted decimal, with classful ranges, multicast 224–239, and default masks 255.0.0.0, 255.255.0.0, 255.255.255.0.

Explore private ip addressing versus public addresses, CIDR notation, and subnet masks, and understand class a, b, and c ranges, their increments, and the role of IPv4 routing.
