More random questions that I dont completely understand from measureup

Attempting some hard stuff this afternoon, math. It’s easier than what’s on the test but I guess I should still be able to perform the basics of IP computation. Maybe that’s worth something, karma points maybe? Or at least explaining to an interviewer that I sort of
know how to do basic IPv4 subnetting and understand CIDR but would like to know more about full DHCP configurations if its possible to learn those sorts of things. Im also doing a few more questions that I normally do with this set, its just what came up so I’ve got my
work cut out for me this afternoon.

I have literally no clue as to why I would need to clear a subnet id but its important to know that to clear it I set it to 1 and not 0 I suppose.

Maybe I should google this to find out why on earth I would do this? If a google it an article
comes up with an author. I think I will email becuase it says he helps nubs in his spare time. Im a certified nubsace with a side order of mcfail when it comes to server for sure. Maybe Ill get a reply or maybe ill get a dont talk to me and go order a fish filet answer haha

Update: I did email the guy, havent gotten a response yet.


This on is a little more interesting with a little less required research, at least for me becuase I try to be through or whatever. So it seems sort of obvious that you should have a comparable box to create an IFM from but maybe not. It reminds the importance of
upgrading. It also somehow reminds me of how inexperienced I am with sever and how long I had been studying work stations at the point which I was testing for a client cert. Not sure why it reminds me of that, it just does.

Like everything else just becuase I one time had a eureka moment with figuring out IP stuff that doesn’t mean I regularly understand it and don’t need to keep going over the same material. This question is one of straight memorization and I can do that for this
but if I was asked anything other than public space I would have literally no clue. The other problem that comes in is that this language in no way directly translates to any cheat sheet that I can find so unless I have a teacher i’m really screwed.

heres the question in question:

Heres the article that the answer references: TechNet

As you can see there is no consistent dialogue or answer key to successfully navigate between the two sets of terms, at least that I can find.


There’s so many questions around RDP that they all kind of start to run together and seem like the same questions with multiple ways to answer them. At least this one is about firewalls which kind of takes a second to process and leaves me with a few more questions about what other commands I can use to control firewalls

Im sure ill probably learn more about this later on down the road depending on circumstances of a production environment.

This one is also not that complicated its just remembering where to click to subdivide a DHCP scope. I cant find a video walking through this but I did find this lab that seems really cool.

Lots of solid additional info on this one.


I really have no idea where to even start with this one and it makes me want to cry like a 5 year old that dropped his ice cream off the cone. Im not sure if its just me that thinks balancing the stuff that sits outside the shell difficult or if average human hands were just not designed for such feats of balance. I’m honestly not even sure I should try to figure this out without some professional help. I really honestly do wish I could find a book or some resource that would lead me to an answer to this problem.

Honestly clueless here, perhaps we could improve training materials a little in the math area? Not one of the 4 books ive read has much information about this. Its not something that is worth covering in ~4k pages of material? </endrant>

In case your curious here is the link that’s mentioned in the answer text TechNet


This next one is do-able, memorize a cheat sheet or basically be able to recreate one (which I haven’t seen any questions related to math that where this simple on the test) and your good. So this is a class A network and then you just search till you find the right number of host addresses. I like this math, its not nearly as impossible as the idea of balancing a melting ice cream ball on top of a cone in the hot summer sun.

The answer makes it sound more complicated than it possibly is but as I’ve previously mentioned I can’t recommend the series subnetting demystified
that’s on youtube enough.
