CCNA: PT. 19

Well its kind of a slow day at work but to be honest its been super hectic so im kind of relived because it was a little taxing to be honest. Not too much other stuff to cover So lets do this blog thing.

Man, that is a lot of info and to be honest here, the best strat is going to be memorizing the answer but holy shit that’s a lot of words to not understand. Or to understand. Either way, we are in for a ball game folks.

Dodgeball - YouTube

I was having a great day until this happened. Man, adulting and education. Anyway, the top part outlines the situation pretty well. The revision number seems obvious as that has to do with replication and apparently computers can have their own vlans for some reason. … the answer keeps going

wow lol

I shoulr really have this memorized by now
Subnet mask cheat sheet - Docsity

Which flows great into this next question. Why I picked the .255 address is beyond me but in a /28 there are 14 hosts and you have to have a broadcast address which would be the .15 in this case.

I have no idea what the hell this internet is, lets find out.

this seems ancient but apparently it uses an RJ-45 connection which is just a regular Ethernet connection.

This, I need to go over. … this is helpful info because it goes over where in the show standby brief output that you find this info

Well, thats all for now. Time to get on the phone and hopefully get a hold of a few people! Maybe… I mean, Ill try haha.

CCNA – : PT. 18

Well, I got some stuff done this weekend but maybe not as much as I had hoped to get done. The big thing this: I did make a beat. Which is totally helpful stuff.

But I have 3 more posts to do (two after this one) and I was hoping to get them all done but that’s not happening. I cant at least get this one done while watching Ghost In The Shell in the background. My mom is also in town. Ive also purchased a new amp. I didnt realllllly need it persay but Im ready for a “real amp” and I got a great deal so whatever.

So a friend sent me this on twitter and I think its helpful.

Here is the deal, I like know things about EIGRP but I still dont really get it. So lets just cover the basics again. When I started reading this I was so confused and thinking lets just get through some questions till we start to know enough information to really actually learn about it. Finally, I feel like im at that learning stage where I can actually fish through this stuff to glean information out of it

After reading this, I know… a little bit more but I’m still focused on learning the questions haha

There is no explanation here at all. I suppose I should just memorize it? I really wanted to look this stuff up but honestly, if they think there is too much info to even comment on it, maybe not lol

I actually understand this but there maybe some missing info with the root bridge situation. That is the key bit but they are right about the mac address. the second bit about the the interface with the lowest number going to a forwarding state is interesting.

So, don’t include an inverse mask with EIGRP. After reading about this in the above article tonight, im feeling somewhat more confident about it but there is still, a lot to learn.

Maybe its the process ID that is local to the router? Yes, it says it is because it says so in the answer. But if you google this you come across the following:,same%20in%20the%20routing%20domain.

So who knows lol

I didnt write much in this but I sure did read a lot and I feel like I got stuff done. Time for sleep!

CCNA – Pt. 17 …

I have done, a lot of blog posts on this and to be fair, there was a lot to learn. In addition, im no where near finished blogging haha. I went through all the questions got about a 50% then went through the questions I missed (where this lot of blog posts is from) and got a 43% on it. So I’m honestly learning but there is a ton of info to cover. I’m going to do these blog posts over the weekend and then next week go through the 100 I missed, and then go through what I missed out of that again and once I’m down to like 20-25 questions that I get wrong, Ill go through the entire lot again and see where I’m at. After this one is done I might check to see about an Azure cert.

Into personal news, my guitar amp is on the fritz for some reason I need to replace it. I got a great deal on it and it sounds great but It was affordable for a reason. I’m going to end up spending about 1k on a new one. On to the good news the Mayor of Atlanta is not seeking re-election. Which is awesome news because I cant stand her and I think she’s really bad at her job. Unlike me, who is currently enjoying a remote position and will probably have to travel some this month or next month. Should be fun. Somewhere weird like Wisconsin. I think California is on the table but I highly doubt I will go there and I really don’t care either way however it seems more likely that people are kind in Wisconsin, for some reason. So lets get this post done and , go to bed.

This is fairly straight forward but these command outputs can get confusing. The problem I have is not knowing what specifically to look for and its probably the “routing for networks line” that may be a dead give away. Not real sure. Hopefully I just remember this is Show IP Protocols. Ill be real honest, this has been the hardest one since the first MCSA due to the learning curve.

Im starting to understand this a little better the second time around because the C answer is actually in the above text. the B answer doesn’t really make sense and im not sure the implication of D.

This is funny. I have no idea why I got this backwards. The window field, I’m not sure of. After reading what it is, I still have no idea.

Why I choose A is beyond me. Its clearly related to HRSP but D is shocking to me, for some reason.

The second go round I didn’t get the “only in topology” part in the feasible successor part. I did get the first part right. Not much to really learn in the text below related to the question at hand. So for now, Im going to skip so much detail.

Tomorrow, is Friday..

CCNA – Pt. 16

Dinner: eaten (pasta)

Wine: drank

Innnernwebs: Ron Bd on

Time to start on number 2, for the night

Anyway, lets do some questions.

First of all, what the hell is switch stacking

The Switch Stacking is a feature that allows us to configure multiple Cisco switches in a way that they appear as a single switch and act cooperatively. For example, if you have five individual Cisco switches, the Switch Stacking allows you to use all of them as a single large switch.

After reading about this I think the answer to the question, again, best explains the concepts they are after here. However, this is helpful

Key points
  • You can add up to nine individual switches in a stack.
  • Only the switch which has a special stacking module can join the stack.
  • To connect stacking modules, a special stacking cable is used.
  • All member switches of the stack select a master switch.
  • The Master switch provides all switching related features and functions such as CDP, VTP, VLAN, STP, etc.
  • Besides the master switch, no other switch is not authorized to run any switching related service.
  • MAC address table is maintained only on the master switch and it references all ports on all physical switches.
  • Each stack has only a single IP address and that is assigned to the master switch.
  • Each stack has only one configuration file and it is managed on the master switch.
  • When a new switch is added to the stack, the master switch automatically configures it.

That’s all for this tutorial. If you like this tutorial, please don’t forget to share it from your favorite social platform.

So all switches are connected but the master switch has the config.

This is what I find confusing in the question it says serial0 but the answer says serial 0. I guess we can assume the answer is right. Regardless, as is almost always the case, there is probably still more to learn but lets get into it deeper at a later date without chasing too many rabbits. I still have nightmares about that from the 2012 MCSA

This is really straight forward in the answer but im not sure I understand what clock rate is or what purpose it serves.

lol so basically nothing but the important note is that a modem ie the network provider, provides the clock rate.

also probably from an ISP?

Not really much to look up here but its good to go over this again.

Thats all for tonight!

CCNA – Pt. 15

Ok, I might get the last two blog posts for this week done tonight. Not feeling super tired and my day wasn’t stressful. Really need to get this thing out of the way and I would love to get all 217 questions done between Friday and Monday and then start on the next set of blog posts. So if I get this done tonight…that would mean… i can start on questions tomorrow! Work has been fairly stressful but today was fairly easy. Anyway,…. lets uha do these things.

I have no idea what’s going on here.

wow, ok. after reading all of this text i kind of understand it. Amazing!

How the fuck am I supped to get all this from two lines of text. … again, after reading the text, I’ve concluded that I understand it.

I didnt put the question in this but the differences between show ip interfaces and show interfaces I find some what confusing. So I wanted to show what the 3 kinds look like

Cisco Ccent - show Commands And Other Related Commands
Show IP Interface
Solved: The Show Ip Interface Brief Command Executed On Ro... |
Show IP interface brief

humm hard to see the difference between show ip interface and show interfaces here. and in the questions answer…

Ok so EIGRP is a common thing and they chose D to mean that it was learned through that got it.

Ok, so here is the deal, this is not that complicated but it requires a lot of thought that I was unwilling to give at the time of going through 450 questions. for starters lets look at this

The Art of the Subnet Cheat Sheet

the /30 should support 4 hosts which is plenty for two servers and a default gateway, so why is this wrong?

according to this.. it will only support two hosts. why the hell is it saying that when …. oh right, the broadcast and the network id.

That last part gets hella confusing to be honest. where the answer is concerned but if you look at the subnet table its really straight forward. going to try to get another one in tonight. we will see…..

CCNA – Pt. 14

Good morning! Woke up a little early so going to try to knock this out before work. Excited about the day and waiting to see how the day goes. Hopefully, we will resolve issues.

This one, we sort of covered in the last post but this is the first part of the equation in PPP connections. I haven’t seen BRI or ISDN talked about much in other questions so for now, we are going to skip that.

This Im finding a little confusing because its saying that the revision number must be configured identically on all switches but thats not true and the clients that have vlans configured, those dont need to exist on the server switch? The top line of the answer is helpful about the VTP domain, version, password and domain name must be the same is helpful though. I guess I’ll figure this out later.
Nothing super confusing here, just think I wanted to cover this again.
This is either wrong or makes no sense because under PRI it clearly says 2 and not greater than 2. E, there are both indicators there so I have no idea how that they came to that conclusion and I didnt really grab all the answer (still learning I suppose and Ill figure it out). F makes sense to me, it says serial and fast ethernet.

As you can see, I’ve chosen 3 when it says 2. For starters DR for packets not listed in the routing table is kind of confusing for some reason. The point being it sends packets to another if it doesnt know where its going. a Stub network, per this, is a network that has only one connected default gateway. So this is starting to click a little better but I still have a ways to go before totally understanding it. Man, this one is hard lol

More CCNA Questions… Pt. 13

So there’s no two ways around this. This test is hard. I’m currently in the 50% margin and really trying to get this done soonish. How soon? Umm well I paid for 3 more months of the VCE player so in that amount of time, ideally. There are lots of other things going on though so its going to be a lot of pressure. This week I’m doing blog posts then hoping to get 150 questions done over the weekend. Given that there are 450 questions on the entire test, this isnt going to be the sum of the questions I missed going through the entire test bank but you know, im going to try. Time for questions!

I dont know what these are. It’s possible there are more questions that I should have blogged when going through the entire bank again but you know, we will find out and ill go through them. Anyway, i wanted to define these.
  • Link Control Protocol – In computer networking, the Link Control Protocol forms part of the Point-to-Point Protocol, within the family of Internet protocols. In setting up PPP communications, both the sending and receiving devices send out LCP packets to determine the standards of the ensuing data transmission.
  • NCP – Network Control Protocols (NCP) used to negotiate optional configuration parameters and facilities for the network layer. There is one NCP for each higher-layer protocol supported by PPP.
  • LMI – Local Management Interface is a term for some signaling standards used in networks, namely frame relay and Carrier Ethernet

Im going to be honest here, this isn’t super helpful info in 2021. Regardless, its on the test.

This, is confusing.

So the good thing is that all the info is in the answer… thats really nice.
ok what the fuck is this.

It’s almost painful to read all of that but I did. Will I remember it? I Hope so!

How is this way better than cisco docs tho, its a lot to take in when going through 450 questions.

Ok im going to sleeeepppp!!!!!

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

Image result for scream

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

Image result for kitchen stadium japan

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.
