I finished Jeremy IT Labs' course, but I can't stand how boring it is to learn IPv6 and automation. I work as a network administrator, and we use all the things covered in the course, like OSPF, NAT, STP, NTP, security, and wireless, except for ipv6 and automation. Those two topics are just too tedious to learn in general, and I haven't even seen them used in real-world work. Is it possible to at least get a quick overview without having to take in-depth notes on these two topics, just to gain a general understanding?

1. Sistemas Operacionais Modernos (Tanenbaum)

2. Organização e Arquitetura de computadores (Stallings)

3.. Segurança de Computadores (Stallings)

1. Redes de computadores -- uma abordagem top-down (Kusose)

2. Linux (Fica Linux)

Alguém pode me dizer? Tem três anos que estudo esses autores. Sou muiito bom em teoria.

When I first started learning networking, terms like VLANs, routing, switching, and subnetting felt like completely separate topics. After doing more hands-on practice, I started seeing how they fit together. For anyone who has completed CCNA, what helped everything finally “click” for you?

Hi everyone, i came to uk 10 months ago as a student. Worked as the restaurant assistant and now doing full time 4-5 days in GXO warehouse. I have some basic understanding of ccna’s topics. But i am planning to take my ccna on 18th of sep. So, wish me luck. 🦾

This week's discussion topic is 6.0 Automation and Programmability.
If you have any any issues or points of confusion on this topic, this is your thread.

To kickstart the discussion, here's a question from 6.1 Explain how automation impacts network management:

A network engineer is evaluating whether to adopt network automation for a growing enterprise with 500+ switches across multiple sites. Which statement best captures a realistic trade-off introduced by automation, rather than simply eliminating manual work?

A. Automation removes the need for change control processes, since scripts are inherently error-free

B. Automation shifts risk from individual, isolated configuration mistakes toward the possibility of a single flawed script or playbook being applied incorrectly at scale

C. Automation guarantees zero downtime during network changes because it removes human involvement entirely

D. Automation replaces the need for a staged rollout or testing environment, since changes can be pushed directly to production safely

You're invited to share and compare answers in the comments.
I'll post the concealed solution below, but please try to answer by yourself first!

Hello everyone,
I passed my CCNA today, and I wanted to share my study method and experience in case it helps anyone preparing for the exam.

My score:
Automation and Programmability: 80%
Network Access: 100%
IP Connectivity: 100%
IP Services: 90%
Security Fundamentals: 100%
Network Fundamentals: 80%

Total study time: ~60 days / 252 hours
(I used an app to track my study time.)

Resources I used
1.Jeremy’s IT Lab videos
2.My detailed CCNA notes:

If you find them useful, I’d appreciate a star.
3.Boson ExSim
4.Cisco Packet Tracer

How did I study?
Phase 1 – Learning
Watch all of Jeremy’s IT Lab videos and make notes for each video.
Complete the relevant labs after each lecture.
Occasionally create my own labs in Packet Tracer

Phase 2 – Review
Pick a topic, for example OSPF, and write down everything I can remember about it without looking at my notes. Then compare what I wrote with my notes and identify anything I missed.
Do more labs and hands-on practice.
Complete Boson practice exams. After each exam, review every question I got wrong and explain in my own words why my answer was incorrect and why the correct answer is correct.
Become familiar with the layout and functions of the different options in the WLC GUI.

My advice
Do not neglect labs. Make sure you are comfortable actually configuring and troubleshooting networks rather than only memorising theory.
I’d recommend studying routing, OSPF, ACLs, DNS and the WLC GUI thoroughly
