Time to start on number 2, for the night

Anyway, lets do some questions.

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

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!

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.

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

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

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…..

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.

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

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!

• 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.

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

No idea why it doesnt work in data centers. https://networklessons.com/cisco/ccna-routing-switching-icnd2-200-105/introduction-to-apic-em

Ok im going to sleeeepppp!!!!!
