CCNA – Pt. 12

Well its Tuesday. I got a flat at work and I think its resolved. Not looking real good for job prospects after this. Nothing is really showing up on LinkedIn or CareerBuilder. Thankfully, my boss is great but offers no long term potential but is happy to announce when you have a flat tire. Awesome. Anyway, this sandwich is awesome. It came from Arby’s.

Nighthawks by Edward Hopper 1942.jpg

Lets get to the questions though.

I wanted to take a closer look at this but again, its diagraming an output. It may be good to know what all these codes are before testing. Regardless of if I’m within acceptable testing range. Anyway, in this case it means router.


I really just guessed on this one but I don’t think I really understand what CDP is.

There is a lot to know and generally I find that Cisco is not the most helpful when it comes to documentation. However, this page is great:

I’m kind of confused as to what it looks like when you configure this or how you configure this which could be in a later question about the output of some configuration. This entire page is helpful, as in, it has information on it but not this specific scenario and im going to be honest, this is actually usefull information and im pretty sure I can figure out group config at some point if I put the time into it

So if im understanding this correctly then the brief output displays it more, organized? This is kind of an odd revelation but good to know, none the less.

ok, what the fuck. I just pick the one that looks maybe right? There is no chart here haha

PErsonally I like the real Sabbath but whatever.

CCNA – Pt. 11

Happy Monday. I’m having a great time and trying to learn a little about electronics. It seems overwhelming but you know, money and time. Thankfully its not that expensive…so far I’m at about 100 dollars into it and have,,, a working guitar and a pedal that will not power on for what ever reason. I think the pedal not powering on is a result of a grounding issue but I could be wrong. The LED doesn’t power and as long its wired right if your getting power at all it should light. The pass through signal works fine though. This is for guitar pedals. I play a lot of doomy type stuff. Basically I like music that sounds like its for stoners in space. I don’t really enjoy marijuana that much but I do for some reason like that type of music. Maybe it was in a past life. Obviously, none of this is going to help me pass CCNA but having a basic grasp on analog circuitry seems like a good idea. So I bought a kit for 50 dollars that’s a clone of a pedal I like and it turns out it has lots of issues. For starters it didn’t ship with a 9v DC in jack that would actually securely fashion to the enclosure. Which tells me, the guy that sells the kit, is kind of just an asshole. He also doesn’t answer questions haha

This is kind of tough because the answer D relies on assuming 100 is the default. Ok, real world you are for sure going to be relying on context clues but its still hard to figure out exactly what’s going on and honestly I think its a mix of “the test” and the fact that I am still learning. The P is confusing

This is interesting to note that some routers appear to show what this in the output text.

Not really much to know here. Other than the “Cisco three tier architecture”? The fuck is this haha

Well thats good to know that it exists. It also makes sense. as in… routers are core, switches are distro and access is users. Amazing.

I got this right but still its good to look at like, wireshark drops

So here is what I think about this. In network administration this could be a helpful defensive tool to learn what people or doing or on the off chance you getting errors with DHCP that seem to be networkwide. This whole concept of hacking being cool because of a TV show is very naïve and frustrating. Your going to want to read this but you will find it also, over the top yet helpful to learn a lot about this from.

Lets define these, I’m not sure what they are.

Lol why the hell would you do that? This makes zero sense, a LAN on fiber. ok. Token ring network makes zero sense in 2021

This is actually interesting. I’m not sure how it works but it does exist and anytime you see Circuit, its guaranteed to be a wan

Synchronous optical networking (SONET) and synchronous digital hierarchy (SDH) are standardized protocols that transfer multiple digital bit streams synchronously over optical fiber using lasers or highly coherent light from light-emitting diodes (LEDs). At low transmission rates data can also be transferred via an electrical interface. The method was developed to replace the plesiochronous digital hierarchy (PDH) system for transporting large amounts of telephone calls and data traffic over the same fiber without the problems of synchronization.

What the fuck, root switch location to be optimized? I’m not sure I understand.

Honestly, this one does not make a ton of sense as it doesn’t say ST “protocol” or anything like that. None of these really say anything about a router location. Which is super weird. and as you can see PVRST isnt even listed on this diagram. It may be a bit of information overkill that we just have to remember. Anyway, here is some for sure southern doom. Maybe I’ll post a loud ab demo of my strat and SG. The squire strat sounds better haha but i still play the SG more? Who knows why. Only god frens

CCNA – PT. 10

Its Friday and its kind of a slow day at work producers.

Image result for adrian modern producers

So its time to get to work on some blog posts and so forth. Anyway, might have this done in the next month or two if I really honker down. I might not take that route though. 2 months is a realistic goal.

We are going to have to figure this one out.

Image result for dixon hill

Here is what I don’t get this link local thing, on a PC that has no outside connectivity so how does this work in a router?

I understand this but I’m not explaining but basically it has more than one interface and is communicating with a specific one and routing traffic to it? I think I’m understanding that, maybe.

Image result for ghost buster

you see this says 2269571 and then it says 90 in the explanation? This is confusing because it seems to be telling me its using 3 protocols and none of them make any sense other than “this one is best” so why not just use that one? I’m confused about this for the moment, but ok.

This says ‘not’ which in fact changes the answer. Not that I really knew this very well but sometimes, you can take a good stab at thing. It’s also good to know the actual order of sla, sla schedule and icmp-echo

This one is actually weighted by the following metric, which you will need to have memorized.

Actually I still don’t understand why the subnet doesn’t need an associated mask. Is this like AI figuring it out? I mean, anything that has that IP in a network? So I can just shoot any ol’ number in there. cool….really im still highly confused by this but its fine.

What are my context clues here for EIGRP?

Oh yeah, those letter things. Ill have to keep reminding my self of that. Next question what the fuck is this load balancing thing??? ohhhh ok, if they have equal “actual equal values as determined by the algorithm” then it “load balances” which, ok. Right. I mean, it works on a larger scale.

Thats all for now but I do have 2 more folders to go through so I might do more later today.

CCNA – Pt. 9

I’m making great headway, learning a lot and now im into the familiar groove of getting through the VCE. Honestly its easier than Security+ but I wouldnt go so far as to say that the material is easy. It is a smooth transition into this after going through the books so I’m feeling well prepaired to at least begin to study the material covered. I realize that seems confusing but you kind of have to drill down with this stuff. Like Dante’s layers of hell.

Image result for gustave dore dante's hell

So let’s break down some of these slides

Image result for hey hey ya video

I pulled this out but you know, there isn’t much to go over here. RSTP is worth mentioning that Rapid Spanning Tree Spanning Protocol is what it stands for and I can promise, I will read that later and be like “I have no idea what that is” but I actually do know what it is. And now I know that there are two port types to use, backup and alternative.

Image result for show ip interface brief

This seems pretty straight forward as well. It’s nice to know that you can abbreviate. in Cisco CLI.

This is one of those “hot standby router protocol” where if you remember that acronym then you golden.

After having gone through several more questions, I realize this to be true. This answer continues.

It took me a while to understand this one but I started to understand that BF is in the routing table and of the options the only routing table missing mac is the C. So I suppose this does make sense.

I walked through these and they look pretty good. May do another post today. Not sure. I have 3 more sets of 5 questions to cover from a lot of 125 questions I went through over 2 days. So clearly, less than the running at covering 1/2 of all questions on the blog. Learning a lot and most of it is somewhat repetitive.

CCNA — Pt. 8

Well, its Friday, I’m at work, at a temp job and its going fairly well. Two other jobs called back and said they decided to pursue other candidates. Which is ok but seriously is no one capable of hiring a network admin in Atlanta? What a weird town sometimes. Less weird than others but regardless I’m entertained. I like living here and I’m focused on studying though running slower than previous years for fear of educating my self out of a job. Which is kind of odd but its ok. Some people still seriously do not think that I actually study for and pass exams and dont simply cheat on them. I have no idea why this is. Probably because they tried to take them and failed because they are extremely hard. I have passed 5 exams without failing in a row. Hopefully, this will be my 6th. We will see. I havent checked into pricing but I don’t think its cheap.

Image result for haters ball

Anyway haha, its 300 dollars. So you know, its a good idea to make damn good and sure your ready. Honestly, I think I’ll be fine if im about 95 based on the material ive seen so far which is around 25-30 percent, so long as im in the 95 percentile.

300 is a ton of money but I mean, its worth it for sure.

This is literally just facts so there isnt much to know here other than 96/8 for HT

I almost got this one right but then went for the additional switch. Which was incorrect. And again HSRP is a high availability thing that stands for Hot Standby Router Protocol (HSRP

you would think that Dynamic Trunk would be a mode but I guess it is in the name. but it looks like ‘trunk’ is also in the answer….Maybe what they are getting at is that turning it on with out a mode puts it in dynamic trunk?

Looks like it is trunk but not dynamic trunk. tricky but ok.

I’m not sure I understand this at all. It makes zero sense to me at this point. I may come back to it and find out.

This is some Security+ type of stuff that would require a lot of info and we might have to loop back around to it. This was not covered on Security+ to my knowledge.

This is slightly confusing. The answer B is not that confusing but the odds of .1 and .2 being in different subnets, seems possible but not likely. Reguardless I kind of understand the point of it being “possible”

That’s all for now. Here is some Nazareth (doom metal dudes love slightly obscure 70s rock. Guess why) I basically get down on doom and love anything from Texas (DJ Screw). No idea why.

CCNA – Pt. 7

Its Monday and I’m making progress. I’ve also come into possession of a guitar amp (because it was unreasonably cheap) and thus had to buy a cabinet to run it into and now have an Orange 2×12 cab in my room which is much larger than you might expect. The guy is shipping the head in the next day or two from Louisiana so hopefully it wont take long to get here. I need to order a speaker cable (like a guitar cable but thicker and made slightly different) and im not sure how long it needs to be because I cant decide if I want to put it on top of my bookshelf or on my dresser. Really I think the dresser would look cooler but its farther away and would be annoying to run a cable to from my guitar. Wireless recevers are not super expensive these days but because of that I think it might be better on the book shelf. Regardless, I’m excited about it.

This study stuff is going pretty good though. Learning a lot. I’ve got 100 questions done and am hoping to get another 50 done today as its kind of a slow day. My retention level seems like its currently above 50% but I’m thinking over all it will still be in the neighborhood of 40-50% at the end of the pretest. Which is no where near where I need to be to pass but I will for sure pass this thing one day. I feel good about that.

This whole wildcard mask thing is, wild.

The 25 Greatest Fictional Baseball Players of All Time | Baseball movies,  Baseball players, Major league movie

There is lots of math here but basically an OSPF wildcard mask looks like the opposite of a regular subnet mask. Why? I’m not sure because they keep talking about binary which has nothing to do with the logic, which is what I’m looking for. But regardless its the same answer that its the inverse of the subnet mask.

I’m not really sure what HSRP is…lets start with that

Looks like the answer is missing the group-number situation but I’m confused about this slightly but I think I’m starting to understand.

I mean, I had no idea on this one and was thinking it would be good to post but as you can see the answers … are in the answer… as to what the lights are.

This doesn’t make a ton of sense but I’m ok with it. After that “will” shouldn’t there not be the word “not”?

I’m not exactly sure what NTP is. I should check on that.

Ok, so it lets the other routers know what time it has and sends that out through 0/0

Also, the -8 pacific is simply the regular label for pacific time so the minus -8 is kind of added information?

Thats all for now. No way am I getting 50 questions done today but maybe 30?

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.

Hank Hill | lemony snippet

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.
