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.
So let’s break down some of these slides
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.
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.
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.
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.
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.
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?
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.
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.
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.
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.
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?
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. https://www.bareknucklepickups.co.uk/pickup/humbucker/warpig (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.
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.
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.
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.
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.
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.
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.
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 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.
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?
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.
