I’ve been doing some lab exercises on three L3 switches using YouTube and PluralSight. I have decided to try using Boson Exam Sim again to try to ‘fill the gaps’.

My first attempt on Exam set A I had failed with 734/825. I studied dot1x, dot1q VLAN tagging, VACL, and a couple of other things.

After a couple of days of study I took Exam set B and passed with 884/825. Three of the questions I got wrong were actually due to not reading correctly (answering too quickly) because after review I determined I had knew the correct answers. Of course those would count against me too in real life so I guess that is part of it.

I was curious how anyone felt about how well a passing grade in Boson ExSim would indicate being ready for the real thing?

I felt like Boson for CCNA ExSim and NetSim were incredible. Hoping it works out for me again this time.

Any advice on some topics that may not be obvious from the main exam topics list that is provided would be appreciated. This means a lot to me and I do not want to take the test twice!

Sorry, I was on vacation. :)

High-quality practice exams should give you an idea of how you will do on the live exam. However, a practice exam can only gauge your ability accurately the FIRST time you see that batch of questions. If you took Exam B and got an 884 on your first shot, that's great! Read all the explanations and fill those knowledge gaps... then try Exam C. Hopefully you will do even better!

Really appreciate your presence on these subreddits. Thanks for the response! I will take Exam C very soon and hopefully will be resting in a week or so.

Boson alone won’t save you IMO Emulate or get real Cats and run through CBT nuggets and COCG

I have 3 catalyst 3560s I am doing some lobbing with. Trying to figure out what I need to lab most or what I may benefit from the most.

Nope. Used Boson Network Simulator software. I did not bother with GNS3 for the switch labs. I would recommend getting a few layer 3 3750s and 2950s used on ebay.

I got 3 off eBay (3560-48x2,3560-24x1) for under $200 and learned so much because I accidentally corrupted the IOS image on one and had to recover with xmodem.

I have REALLY enjoyed adding them to my home network and going through labs like Etherchannel and RPVST etc etc.

The puck was clearly loose and still had momentum.

I mainly used INE, CBT Nuggets, and then a course from StormWinds provided by work. I also did looootss of labbing in my homelab.

Where would you recommend getting your home lab stuff ? I want to go with real stuff as I finished my CCNA a couple of months ago and used sims from Boson, but not sure how price / value compare.

Congrats on passing the exam and good luck on enhancing your career and skill set!

Thank you!!

I would totally recommend a real lab, especially if you haven't messed with physical gear much before, take a look at my post history if you want to see my setup. I bought almost all of my stuff off of eBay and/or state government surplus sales.

I was provided boson for work and I really didn't like it, something felt a little off to me, and I couldn't put my finger on what it was. How did you like boson?

I thought Boson ExSim and NetSim were awesome. I just want to have a real lab too.

Thanks for the response.

In your BGP video you state it used TCP 129 but that doesn’t seem correct?

I just wanted to share that I had got my CCNA about 8 years ago and it landed me the interview/job to really help take my career to the next level.

I just renewed my CCNA today!!

Keep moving forward and you still have it done in no time.

Did you forget "conf t"?

Yeah you are in enabled / privileged exec mode which means those commands should not be valid.

You must first enter ‘configure terminal’ or ‘conf t’ to enter global configuration mode.


I thought I did much better in ICND1. The questions just seemed more difficult on this one and I even had to completely guess on a couple.

The very first question really set the tone for me as it was about APIC-EM path trace tool for ACL and it was check the 3 correct answers type of question. I was stumped immediately.

I ended up with only 2 minutes on my timer so I know I took plenty of time on questions to be sure I was reading them correctly and thinking it through.

I really felt like the questions I did get correct carried the heavier weights because I did still pass at least.

I used all YouTube / PluralSight / INE / CBT Nuggets / Chris Bryant / Keith Barker / Jeremy Ciora / etc. No books.

Also I used Boson NetSim and ExSim for CCNA. You really should go for the Boson products if you have the budget.


If you can afford it. Boson. ( I haven't used it myself. But the general consensus is that they are harder than the real thing. If you're doing well on the Boson exams, you'll do well on the real thing.)

  • If you can subnet very quickly in your head
  • Done loads of labs in PT
  • Know your show commands
  • Know the material enough to explain it without looking at resources
  • Knowing the material in general

I'd say you're pretty much set.

Just want to say Boson also makes an amazing NetSim product that is like Packet Tracer and GNS3 etc.

It also comes with a ton of nice labs that will gave you very confident in the CLI. Also you learn a lot from following through with the lab material.

I know you cant use calculator in exam but in real life , do you guys use subnetting programs to make fast subnets? Or do you still do it manually

You remember it eventually like you would a multiplication table or anything else like that.

You start seeing the same numbers (powers of 2) and it becomes as fluent as reading (skill of a 6 year old for me).

I used YouTube videos to study for the CCNA and also bought the Boson CCNA kit (NetSim+ExamSim).

I studied and practiced for the composite exam essentially. I still had a little trouble with some of the questions, but I think I was able to cover most topics just fine. The Boson exam is very close to the real thing and having the NetSim is really great to apply all of the ideas and tech that I had to learn about.

Since I was studying for the composite I already have a good head start on the ICND2, but still have some gaps to fill like EIGRP, HSRP, etc.

I went to the Cisco site and made sure I had some knowledge of how to explain, implement, and troubleshoot each topic on the exam topics list. I would say I only had to answer questions on half of those.

I primarily used multiple YouTubers videos on CCNA/CCENT material to get multiple points of view on the same subject. Even though that takes more time and can sometimes be a bit tedious it really helps fill in the gaps for each of those subjects. I also searched out every free exam I could find on Google and YouTube that also really helped in the end.

Study hard and take care of yourself before the exam mentally and physically. Take the day of off if you can and I personally crammed on my weak points right up until the test. If you fail just focus on the weak points and schedule another exam in a month or so.

That includes netsim which lets me create virtual networks and configure them from scratch as if I had all of the expensive equipment in real life.

Curious, what did you use to know when you felt ready enough for the test then? By that, I mean did you look at one of the pages online that says what the test covers and then look up each topic in videos?

Yes pretty much and also any questions in the Boson ExSim that was beyond my knowledge - straight to YouTube.

I like that thing that you did.

Just curious if you have checked out cinemachine package? It is a unity product and is super slick in my opinion also easy to use.

Hmm do you have the scale/position of the objects locked in with ctrl+a in object mode

Original Poster1 point · 8 months ago

Yeah async seems to hang as well. I should also say that this is for VR so the user can turn their head and such. But if it hangs then you just get a static image in the HMD that turns with the user. I guess I need to load into a small scene like you say and then load the big scene in the background. Unfortunately async doesn't seem to do that. Am I missing something?

see more

Maybe should just fade to black for loading?

Coroutines are great for anything that needs to wait ( or yield ) a certain amount of time or until another subroutine returns.

You can use 'yield return new WaitForSeconds(1F);' or 'yield return StartCoroutine( FindNewTarget() );'

UPDATE: Unity is working fine with the CV1 plugged in a different USB port. (newest Unity) Oculus requested an update though, waiting to see if I can get it running in Unity.

EDIT: Working in Unity perfectly fine. To anyone who has this problem, Switch to a different USB port!
