CCNA – Pt. 6

Well its friday, I had another interview for a temp job yesterday and I think it went it ok. No real complaints but for some reason people have a hard time believing that I actually acquired certs through study. The point being I work hard, get good customer service stats and the economy isnt great and I have trouble finding stable long term employment but keep plugging away at these certs to be told I haven’t done things that I have in fact done. It’s fine, do what you want but im going to sit here and keep studying and working hard regardless of how it makes someone feel that I like to work and learn. Not sure what is so complicated about the fact that im a smart hard worker that engages well with end users and doesn’t like to play games but prefers to drive results and provide solutions on any scale. Whatever, there’s a pandemic and everything is absurd. Like education does not mean any thing yet they require it but at the end of the day someone’s ego or emotions around a situation is more important than the end results. For example, what does the word helpdesk mean and what is a specialty helpdesk and why did you pick different terms for them. Was it so you could belittle people and make your self feel important? Regardless of if im super polite and ask questions pointed in a direction of respect or cut to the chase with bottom lines, ive found the results are usually the same with that type of personality that isn’t looking so much for results driven architecture but seeking some sort of personal validation that has nothing to with corporate (which often times, if actually results driven and people focused, looks somewhat like small socialist communities validated by Marxist ideals) goals.

Fearful Symmetry: Allusions in Watchmen — Chapter 6 of Watchmen ends with a  quote by...

I really like that quote and this came up from last year as a flash back on my Facebook. I don’t know, I guess some people take existence seriously and pay attention to what’s going on.

Well, lets get into some questions

Still slightly confused about the EIGRP stuff but I’ll check into it. So lets look at that and the show IP output.

Cool, this actually covers both. The guy kind of hotdogs a bit without getting right into detail but its still very helpful helpful.

This is much more helpful, overall but he does cover (lol) what EIGRP is. Going to have to eventually make like a diagram to understand those.

Im confused as to the difference here between speak and active but this looks like some OSI BS. I may or may not need to really figure that. We will see how many questions have this on it. You know its like drilling down thing I do. Obviously, I’m putting more research time into these than the previous ones but you dont want to chase rabbits too hard just yet.

My question is why does this even exist? if every router has to have the same number for this process why does it matter at all? This is simply a bit to be misconfigured. Its helpful to start understanding the CLI. I’m not sure how to say that. When I say ‘the CLI’ I mean the nomenclature or verbiage around the output and the displays of the commands.

This is probably a google as the answer output is slightly confusing to me. actually this is more than slightly confusing. This is hella confusing. So far no luck on finding more info on YouTube, so I’m going to move on again and maybe come back to this but I did find this helpful. The Cisco docs on this are Cisco docs and this is a situation that appears to require some amount of experience with the command in a live environment. This website is cool but this state thing does not explain the full/dr thing while later showing that in the output of command haha

leaving me to think the world is /null and without value of even 0

This is really easy if you remember the layers lol, which obviously I didnt.,describing%20a%20networking%20system’s%20functions.

lol ok “All = Application Layer People = Presentation Layer Seem = Session Layer To = Transport Layer Need = Network Layer Data = Data Link Layer Processing = Physical Layer” This is blessed assurance to me.

Anyway, lets keep making the same mistakes and being the same type of people and wondering what is going on. All the while not realizing the root cause is insecurity that we that try to fix by feeding our egos and caring nothing for truth. That’s all for now. About 100 questions into this. It’s learning and its hard haha but its do able. It’s, you know, a new thing that requires a lot of diligence to understand.

CCNA – Pt. 5

This is going pretty good. I’m learning and getting the hang of things. On a pretty basic short term project that may last a few months. No one is really sure but I got to come up with something perm or there may be some problems with, you know it costs money to live and stuff. Which is problematic for some reason. Any way, lets do some studying before I start talking about average income scenarios for the certs that I have. Really liking this one and the studying, is going.

I dont really understand this at all to be honest. Route one goes from nothing to the second router. Assuming that takes all traffic in the attached vlan that its acting as a gateway for and pushes it to R2

Ok, this is actually where subnetting, starts to click. As in, see why would you make a route for every destination in a subnet when you could just target the vlan and then send all traffic to that router. This is actually interesting but realizing that R1 is a default gateway is a helpful start.

ok lets take a look at the basics before we look at what the answer says the basics are and realize, this is a lot of text to read on a test… the second part isnt really related to learning. So there are a lot of terms here and they all kind of mean the same thing. Which is a thing in computers for some reason haha

This I found super helpful!

This is also helpful

I almost got this one right

Ok, the fuck is a trunk? I think I sort of understand but not really.

So basically its a link between routers? I think I’m good with that. That was really all there was to cover here.

Basically RIP sucks so classful must mean its terrible. IE doesn’t pass through subnet masking info. I may have to come back around to this but we will see.

But honestly, thinking not.

Also its EVH’s birthday and im wiring up a guitar tonight using his schematic. You wouldn’t think this would make a big difference in tone but it actually does. This photo is hilarious just FYI. There s some basketball back stage business you may not be aware of. A music man?

CCNA – Pt. 4

Well it’s Monday, I’m at work and I have a freshly repaired car. I had fun working on it and I think I’ll keep going down that path since it seem vaguely trustworthy at this point and buying something used seems to be in the 10k range for some thing in any way decent. That kind of stinks but it lets me know that its worth it to keep maintaining my car which is worth like 1.5k max but I have zero issues with it overall. I have to put freon in it during the summer and I need to change out an axel. Probably do the front rotors too but all in all its better than spending 10k on a new car. I also like working on things. Shockingly I find it satisfying.

I also need to rewire my guitar that I took all the electronics out of and replaced. Using a Bareknuckle Warpig in the bridge. It’s a 100 dollar guitar that the fretboard radius is different from the tune-o-matic bridge radius haha but it should still sound good and play relatively ok. Excited to get that done tonight. (i play doomy style stuff mostly like sabbath or at most technical Baroness ,)

So lets do some of this study stuff.

For starters I’m not sure what EIGRIP is so lets figure that out.

Oh yeah, we may have seen this one other time. Now, after reading this and understanding the answer in yellow, I’m starting to get a pretty clear picture of what is going on and how this works.

This one was supposed to be on post 3 and I put 6 questions then later moved it over this post.

The answer to this is fairly straight forward even if I don’t know CLI super well but I’m not sure what ASBR is and lets re-define OSPF, we sill start with that.,in%20a%20variety%20of%20networks.

I think this sort of makes sense and the EGRIP think is kind of amusing as its a proprietary thing. Wondering how companies like Juniper deal with this as they seem to still sell routers. Lets go on to ASBR

The concept of border or boundary or DMZ seems to be being phased out for some reason. I find this kind of annoying but it doesn’t really matter as they still exist but the nomenclature is different.

Alright, well I’m aware frame tagging exists and as far as how they differ, I’m not sure. It does say in the answer but look at that last bullet 802.1Q and realize that after a packet leaves your Cisco only environment running ISL, the border router tags it with 802.1q? Or do you have to use frame tagging? So many questions.

So, first of all, we can read the answer. Second, I’m still confused as to if every time a frame is routed if its tagged because it seems to indicate its for VLANs but I think I will get a handle on it eventually. I did find this sight helpful.,sent%20across%20the%20trunk%20link.

Anyway, I think I understand this enough for now and can remember these concepts.

There isnt much to cover here but I think its interesting that the they add linux commands as an option here. Its a good note that they used “ping” and not “ping IP” to get to this menu.

This isn’t saying what command gets you into config mode but its asking what the CLI prompt shows when its in config mode. I found this helpful though I may need to watch the entire thing to understand what router# is. Its probably the same as switch# but this is on a router haha, thats what I’m assuming at least.

That’s all for now. Learning a lot and taking the time to understand what’s really going on with various things. It’s still slow going but you know, I’m not in a huge rush to get this as the next thing I’ll be told is that I’m over qualified.

CCNA — Pt. 3

Well its been a day, going to look at a car. Might buy it tomorrow. We will see how it goes. The entire thing is nerve wracking and annoying but my birthday is like a month away and I got my tag renewal notice so maybe I wont have to deal with that. Regardless this whole ordeal is quite frustrating to say the least and I think it might be a decent idea to just hang on to the other one just in case. Regardless, I’m pretty sure I have to get a new car and this whole thing is a giant mess. I’m not saying im on my own or up a creek without a paddle or have no faith in the economy or peoples ability maintain employment due to no fault of my own or anything but who cares about any of this at all right? Its just haphazard intentionless emotion that drives us. Now after this long drawn out scpheel about nihilism and why I should not be in this situation lets learn a few things. Honestly it could be way worse but I’m still highly annoyed

Lol this explanation is not much help. As you can see I got one of the 3 correct but I find it amusing that you can technically use a class A subnet but actually subnet into like 15 ip addresses which is absurd because the entire point of using classes for subnets is to indicate that this is large subnet this is medium subnet and this is a small subnet but it doesn’t really work out like that in the real world. During the 2012 MCSA I found these concepts fairly difficult.

What the hell is this? I’ve never heard of this before.

Ok i highly doubt this is actually in use but maybe. But ok, its clock rate.

However, now that I know the difference between these two, this at least starts to make more sense. I did get C right. However, I have no idea what the indicator that its a DCE cable is. I think its because its showing a clock rate in the output for ‘show running-configuration’. I also don’t think you can connect a DTE cable to a switch/router. This diagram is helpful but it says modems.

I’m not really sure what source-quench messaging is but it says it to avoid buffer overflow. lets cover those two fairly quickly

So its all like “slow down there Hoss, goin a little too fast!” to prevent hacking. Probably just sends this image.

“that face you make when they ask why you got grape jelly with a sausage biscuit”

This is kind of weird question debating terms because the user logs into the interface. This is really just over complicating something basic but I’m following it out,,,, at the moment.

Thats all for now.

CCNA— Part 2, No creative title here’s

Well, I’m pretty sure I need to buy a new car. This is a huge bummer for several reasons but thankfully I’m pretty sure I’ll be ok. My car wouldn’t start this morning and I suspect its the alternator but I could be wrong. It has a few other things wrong with it and its got 200k miles on it. I bought new tires for it last year and was hoping to get full use out of those but whatever. I mean, I cant get into debt on a car because I don’t exactly have ‘stable’ employment so its a bit scary. So I think I’m going to investigate my options for purchasing. I bought a battery charger thing off of amazon but it does not work. Or it didn’t this morning. It works great for charging phones though. Starting cars, not so much. My aunt took me to work and I honestly didn’t think to try jump starting it. I found a car I like a lot that’s in my budget. I’ll try to make it happen, maybe today. I might have to pay a little bit on it but it shouldn’t be too much.

This stuff I’m kind of aware of and sort of read the answer but grabbed the question to cover this anyway. I’m not really sure what it means by ‘relative amounts of traffic’ but rereading the information it seems ok.

Ok, I dont know how much of this will be on the test but it seems like a good thing to learn about. According to this its basically running ICMP and printing results. Why you would run that from the destination device is beyond me.

So anyway, that’s kind of fun.

This get’s confusing. According the this the source/destination IPs are the actual computers but the MAC addresses are the routers. I understand that but is it consistent?

If I’m understanding it right, this is much easier than expected.

The question here is what the hell is overload? Port Address Translation makes sense to me. Good to know that.

Really, I need to go over what ISDN is.

So this is public internet? It’s kind of funny because every thing hits that at some point and the entire thing becomes a huge misconstrued ball of terms. I’m slightly confused by packed switching but I guess we can cover that later.

CCNA— starting into the vce questions, Part 1

So I started into the VCE yesterday. Again. They let me purchase it again at a highly discounted rate, which I was thankful for as I downloaded it on a work computer only, apparently looked at about 10 of them, realized I had no clue what was going on and started into the books without checking on the VCE again only to find I didnt have the file and couldn’t redownload it. Anyway, I’m now at about a 50% rate after going through them, which is a vast improvement. There is a lot of material to cover.

I feel like I should know this and looking at it now im not really sure why I didnt get it but I wanted to define IP Sec anyway.

I’m not really sure how its different from a VPN and this didn’t really help to clear that up much but lets move along. I did also find this though.,restrict%20user%20access%20with%20SSL

I’m not really sure why Included this one as this is one of those questions that’s kind of tricky and opinion based. It says not a benefit to users which you dont think “this should benefit the cloud company” instead normally.

Man, you know. I learned this and then sort of for got it. Shockingly 802.1x can be confusing. Now get this, AAA authentication is used to control access to the port. Which you would think would be port security. Nope.

This one was a total shot in the dark and I got it right. It’s going to take a little bit of time to figure out why. Honestly, this is one of those things where I might loop back around to it after doing more more CIDR to get more familiar with base line concepts. It may be really easy once I understand that and chasing down a rabbit doesn’t seem like a great idea at this time. What does seem like a good idea is understanding OSPF. (also, it is so rare that you have to use any networking math in production and to be honest your time would be better spent learning some basic things about coding)

Now I know what they are talking about but I have no idea what the 63 is for to be honest. I’m assuming its a mask of some sort but the answer isn’t very clear on that. May require further research as we go through the learning process.

I pretty much understood this but had questions about the verbiage. That’s a long string of commands to keep straight in CLI. To be honest, this is one of those “memorize the question” scenarios. At least that’s what I’m assuming. I haven’t taken a Cisco exam before but based on these I think that’s probably a safe assumption.

Ch. 19 – Understanding Ansible, Puppet, and Chef (the end of the CCNA books)

Well, here we are, at the end of the book. Finally. Honestly, I’ve learned a lot. I’m sure I could have learned a lot more but its like uha, tupac said, uha life goes on. Anyway. I Have heard of two of these. Puppet, I’m vaguely aware of what it does and its pretty old Ansible, not real sure. Chef?

I don’t know why we are covering this to be honest but I found this helpful:

To me, D makes sense or possibly A.

A and B. You should have ACL’s with logs on those bad boys. If you dont, well ok. C would also be nice and D as well. Seem like kind of wish list items to me.

D? Does this seem like GP or is that just me ….

A uses push/pull

A and D? This is a dumb term lol

Welp, that’s it for the books. Time to get into the VCE next week. Might be a while before I start posting again. I am going to go through the entire VCE and pull out stuff I don’t understand and then blog those questions. No idea how long it will take.

Ch. 18 – Understanding REST and JSON

Welp, I’m going to do two of these and then jump rope for 10 mins and run a mile and probably be done for the day. I bought some of those band things to help with pull ups. Apparently I can set at a door that has about a foot drop so my arm is full extended and do 150 lbs on each arm fairly easily. Not sure why I cant do a pull up. This makes me think I should try it some time. For now, Ill keep doing 20 over and 20 under along with a “kettle bell” work out but those are stupid expensive so I use a tub full of brown sugar lol

On to the topic at hand, I really don’t know much at all about this so I’m excited to learn!

Lol, I should seriously know this. My guess is A or D. For more info on the basics (of which this is not covered) check here (the process to change link text is slightly painful at the moment but its a tech target article)

I have no clue and I’m going to let the answer speak for its self

I’m assuming D is a pointer if not is C. What is this URI thing? At first I thought it was typo but it is not

Good to know!

A and maybe B. I really dont think its D and C seems odd for some reason

I think its B and D. I really like this coding stuff. I should know more about this stuff. lol okay so A does make more sense here.

I’m going A and B

I’m not reading this. That is green. Not grey and every answer is in D so its going to be hella confusing. Off to korger to get worsechsire sauce, soda, cheese and 1 thing of brown sugar.

Ch. 17 – Cisco Software-Defined Access (SDA)

I’ve got this, and two more to go and then I’m done with the books. Off Monday but have interviews set up Monday and Tuesday. Monday is for a remote NA/SA spot with Race Track (large regional gas station) and Tuesday is with a recruiter to follow up on a previous engagement. There are few things out but most things pay reasonably well. Excited to see what happens. Also purchased a decent pickup for a guitar and I’m going to put it in my self and pull out basically all the wiring out of a cheap guitar I purchased and rewire it with just one pickup and a volume. Its currently got two pickups, a switch and volume/tone in a cheap LTD SG copy. I need to learn soldering for varying reasons but I mean, I essentially work on electronics and might be good to know some basics about checking things with a meter and putting things together. Currently I have no use for stuff like raspberry PIs but I see the use in learning to put stuff together. I think I will also buy a kit for a fuzz pedal that comes with all the transistors, the board and all that stuff and you basically solder it together. I bought a 300-500 dollar pedal off of Facebook the other day and I got it for 125 dollars because one of the switches doesn’t work right on it. The switch doesn’t really do any thing but if I replace it I can probably make money on a resale if I feel like it. And I would probably take that money and buy a phaser pedal lol.

Lets uha, do this CCNA thing…

Dude, I’m aware of this in virtualization and Hyper-V but I have no clue on this in Cisco world but lets give this a stab. Normally, In Azure the function that is every thing is called A. In this case of SDA, thats some how not CLI, what the fuck lol ok boomers. OK…. Lets go with C

I mean, again B?

No idea.

None of this matters in Meraki? .. Cop alert…. yeah we got this one… Honestly no clue what the “answer is”

Again, no clue.

Very, Very good. A and B for sure happen. I mean, routs exist. D is a plan, I mean, ok

Well, I may do another one in a little bit and then start into the VCE Monday but we will see how it goes. Anyway, This is probably my favorite Sabbath riff.

Ch. 16 – Introduction to Controller-Based Networking

I could possibly finish this book out tonight but I probably will not. Not much to talk about but its been a nice day. I have spent it exercising and applying for jobs. I have two interviews with companies tomorrow. I’m not sure if they know this blog exists or not. I do put work into it though. One is for a less senior position that its like a 3 month contract and one is with a company I’m pretty sure I have worked with in the past that is a direct hire position.

Question time.

Best guess is C. I was wrong though. I don’t know if I will need to know this and at this point im skipping looking these up. If it comes up again, I’ll look into it.

Right, IP tables control routing. One would assume D. So here we are.

Maybe C per the info in the previous answer.

I would have to take a total guess at this. If it comes up again, I look more into it but its one of those bits of info that’s really kind of obscure and wouldnt really be helpful in a live environment unless you only did contract work.

This is a total guess question and this may be antiquated information but my best guess is A. Spine doesnt make sense with leaf. It seems like it should be branch, right? its probably B and C

Well D is Meraki, and that shit is great! Maybe A and D?

This is what I was listening to while doing this. It’s kind of odd. This is a Japanese band that’s been around for forever and they are, cool people. This is a conceptual album about … UFOs and so forth… noises from beyond.. that plague….

Have a great night!
