CCNA Book, Ch 14 – Analyzing Existing Subnets

While I am enjoying the math questions to some degree (i’m for sure going to re read the entire book once I’m done with these and may offer up additional postings of notes or chapter questions, not sure yet) it seems obvious that the real world applications of having to use networking math in your day to day job is not likely. This chapter is applicable to…hummm,,, the type of person that would have to figure out subnets that are existing without using network documentation that points out what is where? Anyway, I think its good to know the basics but if you run into an interview where they ask you more than the basics it might be a good feeler for the type of company and team you would be working with. Most people don’t really need to know this and I’ll be surprised if its on the test. If its in the prep questions though, there is a good chance that it will be. Which means I’ll probably need to be much better at it than I am. I which case I’ll probably have to cover some less confusing material than the book. Honestly, class room material might actually be beneficial for this type of thing. However this would require and engaged and enthused teacher for it to really set it so that’s kind of a null point too and again we circle back to the old “do a bunch of homework” point. Which seems to work very well for me!

Anyway, letttass top (ignore) do this whole quesiton thing and get some shut eye, partner!

lol anyway … i can read you know. Just so you know. What it says. Linux1 420highway69

im not sure I understand the question. Is it asking that would be the same on all the addresses and that would mean ‘equal’? I mean, the subnet is always going to be the same. The hosts bits would obviously change. The network would be the same. uhhh D?

Cool, next question!

d and A best guess.

I don’t understand this ‘host’ part thing. look at the last sentence haha. it says “must not have a value of” which means, im assuming im correct.

D lol is too smal so it must be C,,, since I just looked at the chart

Ok, this one has to be D right?

Now, this is legit confusing because hes using a weird numerical sheme where .255 in isnt the broadcast ID. Thats what im assuming anyway because a /30 has 4 addresses in it so starting at 96 makes 0 logical sense but is do able.

Normally A would be the answer but we have popped in this sick ass new mushroom head album so who fucking knows haha

b? See this, this is discouraging people like crappy pirate signage.

I mean, hes not wrong but this is all ‘a mystery’ that is basically impossible to solve. Anyway, I think that’s enough for today kids.
