A set of seemingly unrelated questions with some interesting finds

Im going to hit the next 10 questions that I was struggling with in this post. Im still unsure about the DNS IPv6 question I posted in the last section. I understand it but not completely. All I can do is hope and trust the understanding comes naturally in time.
Still feeling a time crunch and a fear of what happens when Im done with all this studying and have nothing to keep studying. Keep hoping for thrift stored books to add to my resume for list of books Ive read with no proof of understanding? That doesn’t sound very
good. Dunkin doughnuts plz hire me this summer so I can server again, thanx.

Moving on from my personal struggles what if we got back on topic with technology? Specifically technology related to Windows Server 12k.

This is confusing, like are you kidding me? This one of a million other things that I need to know currently that I could possibly google in a real world scenario? Out of the options I was able to realize that an ACL was at least a good start but I had no clue about the switch vs the adapter. Honestly at my current level of experience and knowledge level im not exactly sure of the specific differences between a switch and a router (hence why I bought Network + study materials that will hopefully still be relevant after im done with 12k).

So now I know that ACLs apply to adapters, still not exactly sure why but I just hope that understanding will come with the backlog of Network + material.


This is on is kind of obvious and I feel like If I would have read the whole question I would have gotten right because its fairly straight forward with the exception of the wording. “still work” is a little vague. You want to block the application or you want it to let the exe
run? I think the point remains the same that its in a location, its not signed and therefore definitionally its getting at the idea of a hash rule. If it was signed and we are approached with the same scenario we could assume a publisher rule as hash rules seem to be a little higher maintenance.

Ok, this is confusing, a path rule deals with a location a hash rule deals with the specifics of a file, kind of confused as to the intent of this answer part. Regardless of the amount of confusing verbs I think the intent remains the same as its very clearly outlining a hash rule.


This is kind of far out as I didnt realize that hyper-v machines used a paging file. Wouldn’t that reduce speed and how does this correlate to the ram they are assigned? I have so many questions and speculations about this scenario but Im not truly informed enough
on this to make a strong decision. However im standing by my decisions that high volume big dollar companies would be better off investing in virtualization than smaller companies that dont have as harsh of SLAs to meet however even with that scenario im assuming some extensive reliability testing would be called for as in a modern era im never comfortable with the concept of a paging file as it usually means running out of ram and using a harddisk (or ssd) for ram.

Well, no I suppose we know that we can preform this action by using the move-vmstorage and set-cm cmdlets with some deep running switches. Though I still havent read any literature about why a paging file is needed if the machine can directly use physical ram. It would be nice to find out the full string though. This answers a variety of questions that had concerning these issues. First of all it makes sense from an efficiency stand point of the ideas of physical memory over commitment however it still feels like a stop gap and im coming to the conclusion that a 1-1 physical to virtualized for physical hardware requirements is a best practice how ever there are work around for that if you really want to push your system however I’ve personally never been a fan of things like overclocking for long term solutions. Its fun to mess around with this sort of stuff but its certainly counterproductive from the standpoint of Hyper-V being a good practice for SLAs. I also enjoy that the author of that last post is a PS specialist but doesn’t give a string for actually producing the final desired result and google seems to be lacking there as well. We may never realize the full line of cmd, thanks measureup and internet. Gosh!


This one isnt super hard but I could see how it could be missed by confusing setting a link with inheritance.

Not a whole lot to discuss here, it’s just important to know when and where to set a link and when inheritance of GP comes into play.


Any thing to do with subnetting Ive found to be particularly hard, especially when it comes to DHCP or any kind of routing question such as this.

Hopefully the exhibit isn’t too small to see, I probably should have cropped the screen grab for higher resolution but then again I don’t feel a whole lot of responsibility as this blog doesn’t see much actual traffic? I honestly don’t even know where to start with this
question. Its seriously one of those questions that you could spend an entire month studying for and still be iffy about the answer. I find it very hard to study for these.

I find it interesting and slightly unplausible that it would end up with a 192. address in the real world given the little that I do know about routing but the 240. was honestly a complete guess. Im sure that I will miss these on the test and I saw a whole slew of these kinds of questions and they were not like this so even if I was to study subnetting to this level I would have missed them. This is the hardest stuff on the test, in my opinion.


This next one is a little confusing as the rabbit hole all ways goes deeper than your elementary level of understanding as in this case.  Im familiar with enhanced session mode to access things connected to a machine such as physical drives (usb and optical) however printing it would appear is a little different.

So now we have a thing called VMConnect and wow is that a good article with useful screen grabs and everything. Although, im not actually seeing something called VMConnect
being enabled. So in theory this is a real thing and without having access to the actual product im limited in my ability to display proof of this technology’s existence but im going to assume it to be true whether or not measureup knows its correct or not.

This question is a much more straightforward definitional type of question where we have a description of an idea that relates to a specific technology so again this one is almost just memorization.

They key here being the support of live migration which relates to SR-IOV.

 photo 2016-03-21 10_zps2yhfnxnz.png

Naturally I assumed that having a tech enabled would hinder live migration (as in the case of pxeboot) however in this case I was wrong and SR-IOV should actually be enabled for live migration to be supported. However I could be completely wrong in that assumption and perhaps I should switch the logic train to the CPU cycles part. Maybe checking with TechNet would be good in this case?

It would seem that the page concerning live migration says nothing about this. This leads us to the understanding that SR-IOV reducing cpu clock cycles is the most important thing
in this case.


That’s all for tonight, had a few others but in a flurry of screen grabs and mass uploading to photobucket some questions are in a slightly disorganized  condition so ill revisit those that im aware of a desire to further discuss as I work through the questions again.
