CBT Nuggets Microsoft Windows Server 2012 70-410 with R2 Updates

I’m currently doing a bit of revision of 70-410 content going through “Microsoft Windows Server 2012 70-410 with R2 Updates” training by Garth Schulte. First of all I already passed 70-410 exam and did 70-410 course by James Conrad, but just to take a break before 70-411 I decided to review 70-410 content + go through 70-698 CBT Nuggets course and take an exams on Windows 10 (yes it counts as a pouse before 70-411).

Few words about updated 70-410 training by Garth. First of all it is fully designed with R2 in mind (James Conrad’s course was pre-R2 + some R2 modules added later) so you can’t find there gotchas and detours related with hiccups related with recent release of a product, instead as it covers stable and current release you will find there well structured up-to-date content and as one expect from Garth well covered PowerShell side 🙂 I also like very good slides summarizing key facts you have to memorize before exam – they provide you with compressed knowledge (I guess I stole getAbsract slogan here 🙂 ) you need before taking your exam. Some examples:

Those slides are just great to review before exam (so it could be a good idea to save some screenshots as you go through the course).

Good job Gath 🙂 Once I done with this training and my Win 10 exam I will be focusing on 70-411. And I’m just wondering how do I inject TCF exam and preparation for it in my schedule…

WDS, DHCP and different subnets

I decided that it make sense for me to jot down different things as I prepare to 70-410 and other MSFT exams from MCSA Server 2012 track, though since recently I have strange feeling that I’m trying to take MSFT exams when they about to retire 🙂 .

One of the questions/topics we had since Server 2008 is WDS and there are some facts to be aware of when it comes to WDS.

  1. Port 67. WDS server uses UDP 67 and this is the same port on which DHCP server listening too. In case of coexistence of DHCH and WDS on the same server you have to configure WDS not to listen on port 67. When you add WDS role on a server which already hosts DHCP role all configuration settings for such coexistence (points 1 & 2 in this list) being configured for you automagically. But if WDS installed first and then you adding DHCP role you have to take care about this manually.
  2.  DHCP Option 60. Once you configured DHCP server not to listen on port 67, you have to configure DHCP option 60 which will tells DHCP clients that their DHCP server is also WDS server/PXE (Preboot eXecution Environment) server. You have to switch on DCHP option 60 and set it to “PXEClient”. In addition to this TFTP should be allowed on FDS along with BINL service (UDP 4011). Note: DHCP option 060 PXE Client does not appear unless your server has the WDS role installed.
  3.  RFC 1542. If your DHCP/WDS server is on a different subnet from one your client reside in then you have to have RFC 1542 compliant router between these subnets, and most modern routers are RFC 1542 compliant. Such routers can be configured to pass BOOTP broadcasts (i.e. broadcast messages which use ports 67 and 68). If you don’t have router compliant with such standard you have to leverage RRAS role and configure DHCP Relay agent.
