It’s 27 pages of CCNA 200-301 study notes with the Packet Tracer commands underneath every concept. All six exam domains: networking fundamentals, subnetting with the magic-number trick, VLANs and trunking, router-on-a-stick, STP, EtherChannel, static routing and OSPF, DHCP and NAT/PAT, ACLs and port security, wireless, and the automation topics.

What this PDF is
Twenty-seven pages that pair theory with the config you’d type. Every major topic follows the same shape: what the thing is, a diagram, then a Packet Tracer Implementation block with the exact commands, then a verify command, then a “Yaad rakho” note flagging the mistake most people make.
That last part is what makes it worth reading. Notes that only carry theory leave you stuck the second you open Packet Tracer. Notes that only carry commands leave you configuring things you don’t understand. This does both on the same page.
An example of what that looks like in practice. The inter-VLAN routing section walks through router-on-a-stick sub-interfaces, then flags the thing that breaks it for nearly everyone: you configured fa0/0.10 and fa0/0.20 perfectly and forgot no shutdown on the physical fa0/0 underneath, so nothing routes and the config looks fine. One line saves you an hour.
The subnetting chapter is the strongest part. It gives you the /24 through /30 cheat-sheet table to memorise, then the magic-number method: take the last non-255 octet, subtract from 256, and that’s your block size. Worked all the way through on 192.168.1.0/26 with network, usable range, and broadcast for each subnet.
Subnetting is worth that space. IP Connectivity alone is 25% of the exam, and Network Fundamentals and Network Access are 20% each – so two-thirds of your score leans on addressing and reading config output (exam topics breakdown).
What’s inside
- Exam overview – all six domains with the official weightings, so you know where the 25% sits before you plan your study weeks
- Networking fundamentals – the OSI seven layers with the mnemonic and the PDU at each level, the TCP/IP four-layer model, TCP versus UDP side by side, the three-way handshake step by step, what each device does and at which layer, and which cable goes where
- IP addressing – IPv4 classes A through E, the private ranges you get asked about, and IPv6 basics: 128-bit format, zero compression rules, and why
fe80::/10matters - Subnetting, worked properly – the CIDR cheat-sheet table from /24 to /30, the magic-number trick for calculating under exam pressure, a fully worked /26 example with every subnet’s network, host range and broadcast, plus VLSM and the allocate-largest-first rule
- Switching – how a switch learns, floods, forwards and filters, VLANs and why they’re separate broadcast domains, 802.1Q trunking, router-on-a-stick with full sub-interface config, STP port states and root bridge election, and EtherChannel
- Routing – static routes and the default route, then OSPF: areas, router ID, hello timers, cost, DR/BDR, a three-router Area 0 config, the wildcard mask catch, and the four things to check when a neighbour won’t reach FULL
- IP services – DHCP with the DORA sequence and a working router-based pool, DNS and port 53, all three NAT types with a complete PAT config, plus NTP and SNMP
- Security – standard versus extended ACLs with the number ranges and where to apply each, both config examples, the implicit deny-all that catches everyone, port security with all three violation modes, AAA, and VPN types
- Wireless and WAN – 802.11a through ax with frequencies and speeds, WEP through WPA3, and the WAN technologies list
- Automation – APIs, JSON with an example payload, SDN and controller-based networking, and where Python fits
- Full command cheat-sheet – every command from the whole document on two pages, grouped by topic, plus the troubleshooting commands you’ll use daily on the job
- Exam and interview tips – how to handle simulation questions on time, and the resume line that matters: write “CCNA trained” until you’ve actually passed, not “CCNA certified”
Who it’s for
- First-time CCNA candidates who want theory and config in one file instead of switching between a textbook and a command reference
- Hindi-speaking students who follow the concept faster in Hindi but need the commands in Cisco syntax
- Packet Tracer learners who know the topics but freeze at the CLI
- Anyone revising in the final fortnight who needs the cheat-sheet pages and nothing else
It’s associate level and it stops there. Twenty-seven pages is a revision companion, not a replacement for a full course. There’s no OSPF multi-area, no troubleshooting-under-load practice, and the labs are described rather than handed to you as topology files. For those, see the workbook below.
About the Hinglish
Explanations are Hindi in Latin script. Commands, protocol names and technical terms are English. So you get lines like “Router ka physical interface no shutdown karna bhool jaate hain” – the concept in the language you think in, the command exactly as Cisco writes it.
If you don’t read Hindi, the command blocks, tables and diagrams still stand alone, and they’re most of the value. But you’ll miss the notes around them, and that’s a fair chunk of the file. An English edition is on the list.
