For MS certs, is it recommended to start off with MTA? Or can I dive straight in to MSCA?

Looking at the paths for MSCA it looks like to get certified its 3 exams? The website doesn't specifically stat the requirement. It just lays out three steps.

Any advice to someone who's planning on taking it? Specific stuff to memorize, out of left field questions, etc?

I'd say pay special attention to the group policy/NTFS permission type questions. Basically the way they word some of the effective permission questions can be tricky.

Remember IP address class ranges.

Know the 802.11 versions and their broadcast ranges and speeds.

Know the basic ports.

As far as left field questions, I don't recall anything too crazy. Taking the practice test on the CompTIA website is similar to what you can expect when taking the real thing. If you're passing those with a high percentage, you'll be fine. It really isn't a hard test, its just that some of the questions asked require you to remember minor things, and multiple instances at that. I used the Mike Meyers all in one books for A+ and Network+. Good luck!

Right now I'm learning how to subnet. And I have a question because its driving me crazy right now.

So basically I'm having trouble understanding how to find the network id's after finding the subnet mask. Right now its asking me to break 192.168.4.0 /26 in to 3 (4) subnets.

I know that since its /26 its going to be 255.255.255.192

It then says to see each of these network id's, first convert the original network id into binary.

Which is:
192.168.4.0
11000000.10101000.00000100.00000000

Then it states to add the 4 different id extensions to the end.

It then broke the binary down to:
11000000.10101000.00000100.00000000
11000000.10101000.00000100.01000000
11000000.10101000.00000100.10000000
11000000.10101000.00000100.11000000

This is where it confuses me because I'm not sure why or how it got arranged like that. How am I supposed to know that its supposed to be the following?
00000000
01000000
10000000
11000000

I'm completely fine if I use the "Happy Chart" to figure this out, but not in the sense this book is trying to explain it. Id like to have a firm understanding how to do it without using cheater charts and stuff.

Inspector_71 posted:

Oh ok, I can explain that now. It's because in a /26 you have 2 bits that get "borrowed" from the host bits to be used as network bits. the 00, 01, 10 and 11 combos are the four possible combinations for those two network bits.

Ok, but how do I figure out the possible combos? Thats the ONE thing driving me crazy right now and I want to learn.

This book is treating subnetting like Rosetta stone, it gives you enough information to have an idea, but it doesn't give you the vital information.

Even that how to subnet a network .pdf doesn't fully explain it. It just gives you the jist and tells you to use the "happy chart"

Inspector_71 posted:

Well, with the 2 bits it's simple since there are only 4 possible combos.

I would probably stick with the 256-Mask=Block size way (that I posted about in the other thread) to figure out the networks, since if you really need the binary you can work backwards from there rather than trying to figure out all possible combos for 6+ bits.

Is it really as simple as how doomisland just said? So in this case there's only 4. Is it simply asking me to count out the number of created id's in binary and lay them out in order and add the remaining 6 zeros to complete the octet?

As in
00 =0
01 =1
10 =2
11 =3

and then
.00000000 =0
.01000000 =64
.10000000 =128
.11000000 =192

IPv6 question.

When shortening an IPv6 address, specifically one containing a string of zeroes it says you can use a pair of colons to represent a string of consecutive groups with a value of zero.

For example
2001:0:0:3210:800:200C:CF:1234 becomes 2001::3210:800:200C:CF:1234

I get how that works in the instance above.

But when its 3 consecutive number sets is where i'm having an issue.

Example 2
FEDC:0000:0000:0000:00CF:0000:BA98:1234 gets shortened to FEDC::CF:0:BA98:1234

In this case, what happens to the third set of zeroes? It looks like it just skipped it and went to the next group (CF). Shouldn't the leading zeroes be dropped and that's it? Why is this third group completely missing? This book doesn't say why.

The :0: indicates that there is a group of zeroes there. The :: indicates that, when all is said and done, put as many sets of zeroes in as you'd need to flesh out the address.

So aaaa::ffff would be aaaa:0000:0000:0000:0000:0000:0000:ffff

You'd never have two sets of :: because it would blow your mind.

aaaa::cccc:0:ffff -> aaaa:0000:000:0000:0000:cccc:0000:ffff

Don't know if that makes a lick of sense.

I think you're thinking of consecutive as "two consecutive", that distinction might be your mental block.

e: Put another way, consecutive is as many as you want. Your loopback address is ::1. 0000:0000:0000:0000:0000:0000:0000:0001.

It makes perfect sense, thanks for clearing it up.

This book never said that :: could represent as many zeroes (in this case 0000:0000:0000) that I needed to finish out the address. It was just like "put these fuckers here to represent strings". I do know that you cant use a second set of :: because then you'd never know how many sets were in each group.

So far IPv6 isn't as bad as I thought it was going to be.

Thanks for the additional comments

I'm definitely not taking the composite, and will going 100-101 ICND1 / 200-101 ICND2 route. The OP says Odom is a dry read, but are there more opinions? People seem to prefer Lammle in general. Personally I'd want he one that's laid out the best and descriptive.

Google preview let me read a few chapters of their books. It seems like i'd take more from Odom's then Lammle, but Lammle would be the more enjoyable one.

Studying for the CCNA and I have the pleasure of trying to learn VLSM. For the most part I understand it and using the VLSM table is great. The type of person I am though I want to figure out how it works, namely how the hell are the hosts determined when using the table? Its driving me crazy!

For example, normally a /27 would have 32-2 = 30 hosts. But on the VLSM table it lists 25 hosts. I'm sure it obvious, but I cant figure it out.

I'm pretty sure its me just not understanding the VLSM concept yet and someone here will point that out shortly.

Its from the latest Lammle CCNA book.

Its asking to create a VLSM network using 192.168.10.0
LANS
192.168.10.32/27
192.168.10.8/29
192.168.10.64/27
192.168.10.16/28

WAN
192.168.10.108/30
192.168.10.96/30
192.168.10.100/30
192.168.10.104/30

It then asks to fill in the table. Everything is great until the host portion because doesn't match up to what it should be. This is the problem i'm having. I get subneting, but i'm stuck here right now.

Don't get me wrong a lab would be cool, they all seem pricey though. I have access to a bunch of old Cisco crap at work, but I don't know if its what I what need. I think a simulator would be the best way to go. Although for Packet Tracer, you need to be a member of Cisco's networking academy or something to get it.

Assuming I could scrounge together some equipment from work. What would be considered a basic lab setup that I could use to study with? All these pre-built lab kit websites seem to be way overpriced and overkill in whats needed.

IPV6 question.


I understand it for the most part except for one issue, and that's assigning subnet addresses. For the last 16 bits, it looks like you can pretty much assign a number and be done with it and then that's the subnet. I know this is probably wrong, but every example I see seems to make it like that.

Example:
0000 = Subnet 0
0001 = Subnet 1
0002 = Subnet 2
etc...

I don't have to follow a range or anything depending on what bits are used? Say for example the global prefix is a /56 which then leaves 8 bits for subnetting. Could I still just assign it as 00, 01, 02? Or does it have to follow a specific range? Like 00, 08, 16? Kinda like how it used to be block sizes in IPV4.

Sorry if my question isn't clear. Everything else I get.

As far as the CCNA goes (specifically 100-101), how in depth are the IPV6 questions? Are they going to require me to subnet an IPV6 network?

I just passed ICND1 (100-101) using the Lammle book and CBT Nuggets.

The test itself wasn't that hard and I probably over prepared for it. I was expecting something a little more difficult. I did the crappiest in the security sections because I encountered a few simlets that were asking questions that weren't covered in the book or nuggets.

I didn't encounter a single IPv6 question either which I thought was strange. There were a ton of subnetting questions, and a bunch of other random trouble shoot this connectivity scenario questions/simlets. I'll knock the second part out in a month or so.

A+ isn't useless and you will learn from it. Its pretty much used by HR when they're going through resumes to show that you meet basic requirements for basic entry level low tier Helpdesk. The likelihood of you getting an entry level job at a decent company without A+ is pretty low. At that point, nepotism is how you get jobs without certs or formal education.
