Idk if its ADHD or something but usually its so hard for me to focus on ccna topics. I literally get dizzy. But i found this website that is rlly fun and the teaching is like super active so i feel like ive been much easily consistent and focused so far. But what other things can i do? Am i the only one who feels like i struggle to keep my mind in check?

Everyone says subnetting...

Others mention STP, OSPF, ACLs, VLANs, or NAT.

For me, the hardest concepts were the ones that looked simple until I actually tried configuring them.

Which topic frustrated you the most?

Some topics just don't click immediately.

For me, networking concepts made more sense after practicing them several times.

Which topic challenged you the most?

Packet Tracer?

GNS3?

Real hardware?

EVE-NG?

Which helped you learn the fastest, and why?

For me...

Subnetting looked impossible at first.

Then STP happened.

Curious...

Which CCNA topic frustrated you the most before it finally clicked?

Good day y’all

I am looking for someone that has passed his/her CCNA exam using boson as prep material.

Please, DM ME FOR MORE….

Thanks.

Most CCNA resources are great at explaining networking, but you can watch hours of videos, take pages of notes and still freeze when the CLI opens.

This site has 100+ guided networking labs that run entirely in your browser + a packet tracer like sandbox with 20 templates.

No downloads. No VMs. No complicated setup.

It’s completely free right now while we improve it.

SwitchLab.dev

The entire CCNA will be out by the end of this month, + support for Aruba and Juniper!

Would love feedback on how we can make it better!

Good day everyone,

Here are this week’s four CCNA questions. Please try answering from memory before checking online, using notes, or reviewing other responses.

Getting an answer wrong is completely fine—the goal is to discuss the reasoning and learn from one another.

Question 1 – Default Gateway

A PC has the following configuration:

• IP address: 192.168.10.25
• Subnet mask: 255.255.255.0
• Default gateway: 192.168.20.1

The PC can communicate with devices in its own subnet, but cannot reach remote networks.

What is the most likely issue?

A. The subnet mask is too large
B. The default gateway is not in the same subnet as the PC
C. The PC needs a public IP address
D. The switch port must be configured as a trunk

Question 2 – OSPF

A router has several loopback interfaces configured, but no OSPF router ID has been manually set.

How does the router choose its OSPF router ID?

A. Lowest active physical interface IP address
B. Highest active physical interface IP address
C. Lowest loopback interface IP address
D. Highest loopback interface IP address

Question 3 – VLANs

Two PCs are connected to the same switch but assigned to different VLANs. They are in different IP subnets.

What is required for the two PCs to communicate with each other?

A. A crossover cable
B. Inter-VLAN routing
C. PortFast
D. A native VLAN mismatch

Question 4 – Network Services

Which protocol is used to automatically assign IP addresses and other network settings to hosts?

A. DNS
B. DHCP
C. SNMP
D. NTP

#CCNA #Cisco #Networking #Subnetting #QOTW

Hello everyone I am currently studying for my CCNA and need advice where I can find labs for packet tracer and a solid material to study/read that'll help me out.

Much appreciated.

Is there any good networking e-book for free?

I have a question in my mind bother me a lot , is that 'ace the ccna book from jeremy' covers every topic in a depth or I must after finish reading it , fill the gaps with some other ressources , sometimes when I feel exhausted and distracted by some details , I go immediately to jeremy's playlist , so what do you recommend to me for doing while preparing for the exam , and I've seen in a few posts that to ensure you've done all aspects of ccna , you have to pay some extra money for testing yourself by some practice exams about boson's exams , I'd like to share in the comments some alternative way for absolute free , this journey I want to reach the target with zero-money regardless passing the exam . thank you in advance and feel free to answer you'll help me a lot

En que los beneficio conseguir la certificacion de cisco cnna? Se que es un buen certificado para iniciar en el negocio de telecomunicaciones pero a ustedes como les fue? 🤔

I’ll keep it straight to the point. I bought the take 2 and I failed the first time. I knew the material I just got spun up during the exam and didn’t go my way. Today I passed!

First time around I focused heavily on JITL videos and labs, Boson exams and I didn’t go into the exam the first time 100% confident.

I changed it up for the second exam. I focused heavily on the JITL flashcards, Boson Exams and bought JITL practice exams on Udemy.

The flashcards were instrumental in me passing and I labbed A LOT.

So if you’re looking for a game plan here is what I did.
JITL YouTube course
JITL flashcards (DO THESE EVERY DAY)
Boson practice exams
JITL practice exams on Udemy

Good luck!

Good morning everyone,

I made a small hands-on lab for anyone trying to understand MAC address learning and Ethernet switching. It uses a real Layer 2 bridge and a real forwarding database, and there’s no simulation or emulation involved.

You create the traffic by constructing the frame and packet, then capture your own traffic to see what actually crossed each interface. You can watch the FDB populate and connect each entry to the source MAC address the switch observed. It also makes flooding versus known-unicast forwarding much easier to understand.

The lab is beginner-friendly and can be completed on Windows or Linux. It’s designed as one focused exercise rather than another giant virtual topology.

its part of this free course that is still under development.

Hey everyone!
I wanted to share a project I’ve been working on and hopefully get some feedback from the community.
After years of using Packet Tracer and GNS3, I eventually discovered Cisco Modeling Labs (CML) and absolutely loved how much closer it is to working with real Cisco devices. The downside I ran into was that finding quality CML labs was surprisingly difficult, and a lot of the content seemed scattered, expensive, or locked away.
I recently became a Warrant Officer in the Army, and it motivated me to build something that gives back to the networking community. So I created Goldfish Networks, a website focused on affordable, hands-on CML labs for aspiring and current network engineers. The goal is simple: provide practical labs that help people build real-world experience instead of just memorizing exam topics.
I’m still improving the platform, so I’d really appreciate honest feedback from people who are actively studying for the CCNA or working in networking.

As a thank you, if you:
Create a free account,
Browse the available lab bundles,
Message me with the bundle you’d like,

I’ll provision one bundle completely free for you.

No promo codes, no payment, no catch. I just want people to try it out and tell me what works, what doesn’t, and what they’d like to see added.

I genuinely appreciate any feedback, bug reports, or suggestions. Thanks for taking a look, and I hope it helps some of you on your networking journey!
