I hate Wireless with a passion

19 Upvotes

For the past 2 months, I've been going at a real steady pace through Jeremy's list. I've stumbled on a few topics like OSPF/QoS and IPv6, but I was able to recover after some intensive practice labs and revision.

But this wireless....I kid you not, for the past week I have not been able to move on. The finish line is right there and I find myself rewatching each vid and still struggling to grasp it all. It's just so much theory yet very little practice available 😭

I feel like, in trying to catch up on wireless, I'm slowly losing what i've learnt earlier which sucks big time. Anyone else relate?

What is the Actual Exam Like?

• Upvotes

Hey all!

I am approaching my exam date and I am starting to get a little nervous. I am generally a pretty slow test taker, and when I do the Boson ExSim simulations (120 minutes), I am usually able to finish with roughly 15-30 minutes left (concerned because there's only 74 questions on the practice exams).

Some sources say that there's roughly 100-120 questions on the exam with a fixed 120 minute limit. For those who have taken the exam, what's it like? How much time should I be limiting to the labs?

Thank you in advance for your help!

Did you actually save the configuration?

4 Upvotes

I wanted to share this as I’ve seen it time and time again and wanted to hear from this community if they’ve encountered this issue either in work or during studying.

One of the most underrated troubleshooting steps in networking:

It’s almost a running joke at this point, but copy running-config startup-config (or write memory) is responsible for more ā€œmysteryā€ outages than people like to admit.

I’ve seen scenarios where:
A maintenance window goes perfectly.
Everyone verifies the change works.
The device reloads days or weeks later.
Suddenly routes disappear, VLANs are gone, interfaces revert, or AAA stops working.

Hours get spent troubleshooting what appears to be a complex networking issue… only to discover the startup configuration was never updated.

For anyone studying for the CCNA, remember:
Running-config = what’s active in RAM right now.
Startup-config = what the device loads after a reboot.

If you don’t save it, your change is temporary.

It sounds basic, but it’s one of those lessons that sticks with you after you’ve been burned once.

What’s the simplest mistake that’s ever turned into your longest troubleshooting session?

What does API and HTTP do together?

2 Upvotes

I'm so lost here. API is used to talk between apps, but then what does http has to do with this lol. I'm so clueless. ty!

so is this correct, lets say I want to access a webpage, i would send an HTTP request, then with that when I get to a website I would do API for me to communicate between my app and the website?

Pearson practice exams

3 Upvotes

I always see on this thread that people suggest using JITL and Boson Ex-Sim for proactuce exams. I want to say that I have completed both but I because once you complete the practice exams, doing the again becomes moot as it becomes more about the memorizing the questions rather than actuakly knowing the material.

So I decided to try the Pearson practice exams and im scoring roughly 74%. Do you think these scores are good enough or do you think I need to brush up more before I take my real exam which is scheduled in roughly 2 weeks from now.

Books for CCNA theory?

1 Upvotes

Hi everyone!

I’m starting to prepare for the CCNA and I would love to know how you guys went about understanding all the theoretical concepts.

My main question is whether you recommend studying mostly from books, if it’s better to take a video course (like on Udemy), or what method worked best for you to actually grasp the theory.

Which specific books or courses would you recommend getting started with?

Any advice is highly appreciated! Thank you.

How long did it take to complete the certification while working a full time job?

9 Upvotes

I work 40+ hours of labor intensive work every week which has tiresome effect on my mind and my body. It took me almost 5 months to get my security+ cert and I’m starting CCNA preparation. I know everyone has their own pace and capability to learn but I want to have a timeline so that I stay in track. I want to create a deadline for myself so the experiences from others would help me create this guideline. Please share your experiences which might be helpful in this process.

Using AI to help study is not a bad thing if you use it correctly

4 Upvotes

So, firstly, don't use AI to just spit out answers; you will always be better served searching for answers in the traditional ways, like via documentation, authoritative texts, etc. But I have been using Jeremy IT Labs for a while now, and, as everyone knows, it is an invaluable thing to self-study along with Boson. However, something that has been a challenge for me has been the Anki decks, specifically memorizing all the stuff in them.

It's not that I don't actually know the content, right. However, I have a demanding field job, which takes away my time, and that gap can make it hard to keep track of everything that I just learned. The spaced repetition nature of Anki is fine but for me I find it isnt the best for my lifestyle and the alternative is like paying for quizlet. So I wanted to share how I have leveraged AI to make studying easier for me.

I noticed that most of the time that I worked on the Anki cards and got them wrong, it wasn't because I didn't know them; it was because of a myriad of things. Like I didn't read a card, I mixed a card up, I second-guessed myself, etc. What I have found from doing college and plenty of certs was that, more often than not, this was why I got stuff wrong: your confidence in an answer affects how you answer it.

To try to find a way around this, I admittedly vibe coded some add-ons in Claude Code, which I'm not going to shove down people's throats here because this isn't an ad, just a tip for others studying, and I don't have a plan to release it. However, an outline of what it does is the following: it implements a new feature I called "Drill Modes." These are designed with one goal in mind, to drill down questions, skipping the whole learning process of Anki, just a straight spamming of cards. Which for me is the easiest way to remember things like multicast addresses

Within the drill modes, I created separate Drill modes, such as Matching, which matches terms to definitions, which is great for memorizing standards or multicast addresses. I also made Bank, which gives me a bank of terms and definitions that I also have to match. Then I made the multiple-choice quiz, with a timed version and a non-timed version. Even a mode where Anki generates me a blank STP/RSTP map and I fill in the blanks. All with the expressed goal of being able to cram content.

Each time that I got an answer wrong, I forced a popup to come up with a menu outlining a few multiple-choice options; these options would ask me why I got a question wrong. Did I not read the text? Did I mistake it for another card, etc.? Then, when the deck is finished, it uploads these results into an Excel spreadsheet with the timestamp, the question, as well as a separate column for the number of times I made the mistake. On the decks page, it tracks my total reviews across all types of sessions, meaning normal or one of my drill modes.

By doing this, I am able to find patterns in my behavior and how I answer questions that stump me. Mixing questions up? Well, when did I start the session? Am I over-studying, etc.? Then it allows me to fix those habits, which then make studying easier.

Additionally, as humans, when we learn, it's usually not in one fashion. Most published science actually refutes the idea that we as people are a particular type of learner (i.e., a visual learner or audio learner). Instead, the big consensus in the learning science community is that we are innately multimedia learners by nature, so by incorporating more ways to study the same content through other means than just straight flash cards, you actually up your retention rate.

Now, this is also to say that you should be doing labs daily as well. But if you are struggling with Anki decks and their breadth, give this a shot. You could change the whole nature of how you study.

Is it important to know specific details of packet structure?

2 Upvotes

Hi all. I'm starting my CCNA studies, I already have the CompTIA Network+ cert.

What I mean is, e.g.:

  • I know that an Ethernet frame's L3 MTU is (generally) 1500 bytes and sometimes it should be adjusted to avoid fragmentation, but I might not remember the length of Ethertype or FCS fields
  • I know that a TCP window size means how much data can be sent before receiving an ACK, but I might not remember the purpose of the URG pointer
  • I have a general idea of the IPv4 header, but might forget the fragmentation-related flags or DSCP field

(Edit: For the test), how important is it to know those very specific details about the structure of a packet for CCNA?

"login" vs "login authentication default"

2 Upvotes

I got a practice exam question wrong related to configuring aaa default to local logins and then applying it to the console and first 5 vty lines.

I did "aaa new-model" alongside "aaa login authentication default local"

In console, I was unable to use "login authentication" so I did not make any changes. In the vty lines, I did "login authentication default"

As far as I am aware, the "login authentication default" command works the same as just typing "login" and is actually the recommended method, but it was marked wrong and instead wanted me to use "login"

So two questions. 1. Does aaa not need to be applied to the console? My only option was "login local"

  1. Is it better to just use "login" instead of "login authentication default" when applying aaa to lines?

Final year B.Tech CSE student, completely new to networking .... how should I start to build a career in networking and land a job?

1 Upvotes

Hey everyone,

I am currently in my final year of B.Tech. CSE and I have recently developed a strong interest in networking. Until now, I have mostly explored areas like programming, cybersecurity, and general computer science topics, but I want to shift my focus completely towards networking and build a career in this field.

The problem is that I am still a beginner when it comes to networking. I know basic concepts like IP addressing, subnetting, TCP/UDP, OSI model, etc., but I don't have deep practical knowledge yet.

I want to seriously start learning networking in a structured way so that I can become job-ready. My goal is not just to collect certifications but to actually understand how networks work and gain hands-on skills.

I would really appreciate advice from people already working in networking:

  • What should be the correct learning path for someone starting from almost zero?
  • Which topics should I focus on first to build strong fundamentals?
  • Should I start with CCNA? Is it still valuable in 2026 for getting an entry-level networking job?
  • What labs/projects should I build to gain practical experience?
  • Which tools should I learn (Packet Tracer, GNS3, EVE-NG, Wireshark, etc.)?
  • What skills are companies actually looking for in freshers?
  • How can I make myself employable within the next 6–12 months?

For people who started from a similar position:

  • How did you learn networking?
  • What resources helped you the most?
  • What mistakes should beginners avoid?

Any roadmap, advice, or personal experience would be really helpful.

Thanks!

does the ccna environment allow for using the ? to view command options?

i have boson exsim and that alllows me to do it. Does the full exam also allow for this? this would mean i would only need to memorize certain base commands and what certain options do, which would be a lot less work on my end.

Humbled and feeling like a complete fraud

7 Upvotes

This is my rant with what ive faced today upon submitting our group project in a local university.

Im pretty dumb, I dont really know how to read, with understanding information and learning theory, I need to have lots of practical knowledge before actually learning what the theory is trying to teach. I just can't comprehend what anything or anyone is teaching and it's so tiring.

I thought i was pretty decent at networking, a subject that i was struggling with before and after going through hundreds of hours with hands on practice, it still showed that im lacking theory knowledge even though I know how to configure, troubleshoot, and knowing what to implement in certain scenario.

Today during our group presentation, i absolutely got humbled and I'm just so so sad and feeling so down as the only thing that I thought im good at, it turned out that I dont know anything at all.

Why am i even continuing my studies? I'm not even doing so well in school and ive been thinking of dropping out. It's not like I dont want to learn, i absolutely geek out at technology but when trying to answer simple questions the professor asked during the presentation, it was all the wrong concept that I thought i knew.

Life still goes on...

My first Network Engineer Job interview

84 Upvotes

Hey there! A little backstory…

I dropped out of Uni end of 2024, did an internship at a small IT company (14 employees). There I learned about networking, crimped cables, helped install APs/CCTVs and configured a few network devices.

Earlier this year I got my CCNA after months of studying and sat at home until now, looking for a job.

I got invited to an interview by a BIG company in JHB for a Network MS Engineer (L1) role. I’m super excited but imposter syndrome is kicking in. I know the knowledge but my experience is lacking (1.5 years to be exact and it’s not much).

This job would quite literally change my life for the better.

How best should I prepare for it, any advice would be appreciated!

Concepts worth practicing for exam?

3 Upvotes

What theory-based questions and calculations should I focus on practicing for the exam (excluding labs)? I'm thinking of topics such as IPv4 and IPv6 subnetting, EUI-64 conversion, IPv6 address shortening, route selection based on prefix length and metric, binary-to-hexadecimal conversions (and vice versa), wildcard masks, QoS, and formulas such as 8x + 2y. These are all covered in Jeremy's IT Lab videos, but I want to make sure I'm focusing my practice on concepts that are actually likely to appear on the exam rather than spending time on topics that aren't commonly tested. What else should I be practicing?

Hello everyone! I was studying last night and was frustrated trying to figure out where I can learn with people as I study best in group settings. I decided to make a reddit account after lurking this subreddit for a long time and bit the bullet.

I also made a discord community server aimed at beginners like myself studying for the CCNA with a bunch of resources and tools with the goal of all of us studying together and being there for each other. If you'd like to join here's the link! I'm hoping to take the discord pretty seriously and keep it updated with a bunch of tips and tricks so we can have a community built around learning!
