I've locked and moved this thread temporaily whilst I clarify with VMware education that they did indeed say they were happy for this kind of information and the copy of the design tool to be done

^Thanks no problem

Some other questions just pending verification for the VMware education team.

Update on the simulator

The work on the simulation page is coming along, The drag and drop stuff is pretty well in place, just working out some last quarks.  The next thing will be to get the connectors working, since the jquery library is using a source / target system with anchors for the connectors I'm going to try and make that work so I don't have to edit much of the javascript if any (Hopefully!).  How I'm hoping this will work is one of three ways:

1.)  Every item will be pre-built as a source or target.  If an item is built as a source just dragging from the item anchor area(can be visible or hidden in the image still testing this) to a target item will create a connector.  Example:  A VDS switch is created and dragged onto a canvas, this item would be creates as a source.  The vmnic or pnics would be a target so you can connect them.  I don't know the limitations of this particular setup  yet so lots of testing is still needed.  This system will not require you to "create" a connector from the Create Button on the bottom of the screen

2.)  Every item will just have anchors in it and you will be able to drag a connector from any anchor to another anchor.  This system will not require you to "create" a connector from the Create Button on the bottom of the screen

3.)  Creating a connector will create an anchor on an image, you then would drag the connection to the other item, or you may have to create both anchors then connect it.

I would like to get the functionality as close to the exam as possible, but I don't know the limitations of the jquery library yet or have fully figured out the code behind it, none the less that's where I'm currently sitting with moving the information on here into a full blown simulator.

I'm hoping if I can get enough spare time I will be able to have some kind of working beta simulator up and running by this weekend or early next week for people to just play around in and test it.  I'd love to have it up by Friday, but we'll see all depends if the java plays nice with us or not :smileysilly:

Just waiting on the education team to give me the green light to release a few new questions:

1 Drag and drop question

3-4 Calculation multiple choice questions

Other then that just working on getting the drag-n-drop and connections working.  Hoping to have some good news around the simulator soon and some more questions for you all.

Drag-n-DropQ3 - Submitted by @ShadyMalatawey

Multiple Choice Calculation Questions.  These are to help calculate cluster sizes ect.

You have been hired to help Labtown design their new vSphere 5 environment and virtualize the current environment.  The current environment consists of 50 Windows servers ranging from Windows 2003R2-2012R2.  Labtown performed an inventory of the 50 physical servers and has provided you with a performance baseline.  The baseline breaks down as follows:

25 Severs with 2 x dual core 1.4GHZ intel CPU's

20 Servers with 2 x quad core 1.8GHZ intel CPU's

5 Servers with 2 x six core 2.0GHZ intel CPU's

30 Servers with 4GB of memory

15 Servers with 8GB of memory

5 Servers with 16GB of memory

All servers currently only use 1GB dual port network card in NFT only providing 1GB at any given time

Labtown's CPU usage per physical server is 1.2GHZ

Labtowns's Memory usage per physical server is 2GB

Labtowns's Network usage per physical server is 60Mbps

Labtown has already picked a vendor and server model for the ESXi hosts that fit in their budget.  The hosts they have selected are Dual 8 core 2.4GHZ Intel CPU's with 96GB of memory and 8x1GB.  Hyperthredding will not be taken into account.

Labtown also requires that the cluster needs to be able to sustain one host failure without impacting performance.  What is the minimum amount of host’s labtown would need to buy to meet the CPU requirements to virtualize the current physical environment.

1. A.)  4
2. B.)  7
3. C.)  3
4. D.)  2

Answer: D

Drag-n-Drop-Q3-A3

The key part in this one is you can use each requirement more then once, which is required to setup the proper host groups / VM groups.

Multiple Choice Calculation Question - Failover Admission Control

1.)  Labtown has hired you in as a consult to help setup a new 12 host cluster.  Each host has 2x8core 2.2GHZ Intel CPU's and 128GB of Memory.  Labtown requires that four hosts can fail or go down for maintenance with the ability to still power up all VM's on the remaining hosts.  The total resource usage by all the VM's on the cluster is 200Ghz CPU, 624GB Memory What percentage of cluster resources reserved admission control do you set in your installation document to meet the requirements so all VM's can start.

A.) 10%

B.) 15%

C.) 25%

D.) 33%

Answer: D

100 / 12 hosts = 8.3 * 4 = 33.3

2.)  Labtown has hired you in as a consult to help setup a new 12 host cluster.  Each host has 2x8core 2.2GHZ Intel CPU's and 128GB of Memory.  Labtown requires that four hosts can fail or go down for maintenance with the ability to still power up all VM's on the remaining hosts.  The total resource usage by all the VM's on the cluster is 200Ghz CPU, 624GB Memory.   If you set the admission control to 33% What percentage of cluster resources does your cluster still have to use to start VM's in the event of a failure with this reservation.

A.) 29% CPU capacity, 32% Memory Capacity

B.) 20% CPU capacity, 26% Memory Capacity

C.) 33% CPU capacity, 39% Memory Capacity

D.) 22% CPU capacity, 28% Memory Capacity

Answer: B

CPU calculation ((422.4GHZ - 200GHZ)/422.4GHZ) = 53% - 33% Reservation = 20%

Memory calculation ((1536GB - 624G)/1536GB) = 59% - 33% Reservation = 26%

Nice Qs JPM .. Keep up the good work

HA Qs have a good trick

In the previous group of MCQs (Cluster Sizes):
What is the difference between the first two Qs (both answered C)..??

PS. Kindly, modify the answer of Drag/Drop Q3: R1,R2 require Anti-Affintiy not Affinity

Hey ShadyMalatawey,

The previous multiple choice questions around cluster sizes the difference is in the final line.   The first question si calculate the size for CPU, next is Memory, next is network.  I think the first two end up working out to the same size, something I can play with the nubmers a bit so its different.  However the memory question breaks down like this:  You need 100GB of memory for all the physical servers and each ESXi host has 96, so you need a min of 2 servers to supply the memory requirements for the servers.  However the questions states the cluster has to be able to sustain 1 host failure, and since each host only has 96GB of memory,  if one host fails in a 2 host cluster, there will not be enough resources to fire up all the VM's so you have to bump the number to 3.

I will see if I can clean it up later tonight and make the numbers a little different.  Also i'll fix up the type-o in the Drag-n-Drop question around the affinity later tonight as well. 

Thanks again,

In my humble opinion, it'd be better if it was just one Q with the required answer is the number of Hosts to satisfy all requirements, given that each of memory, CPU and network will need different number of hosts and the answer is the highest one (Worst case scenario). For example, CPU requires 3 hosts to be satisfied, memory requires 5 and network requires 2. The answer should be 5.
May be I can also send you a couple of Qs by late tonight

Sure sounds good.  I can also update the question a little later to merge them.  I can play around with the numbers so you have to select the highest number type of hosts like in your exam.

Also I maged to bug one of the developers I know the other day and we managed to get around many of the walls I was hitting with the connections with the javascript.  So if I can get the rest of the pictures created tonight and the sources/archors setup I should have a working demo for one question pretty well up tonight.  I will hopefully post the site later.

Hi all! First of all great work and thanks for trying to help with our DCD studies! Just as a quick pointer but the question DCD-Q1-A1 you've answered using the diagram (which is still useful) is potentially wrong IMO. The reason is that you've introduced two points of failure by keep the DMZ and the Management on the same physical nic card so that if it fails, then so does that service. Happy to be told otherwise though but having done the DCD twice already it's worth pointing out so no one else makes the same boo boo as me! I'll be feeding in to this myself after my 5.5 exam this Friday (unless I reschedule) Hopefully it will be a pass this time!

Ahh good catch Wardy8124, I will append that drawing and upload it when I can   I'm just looking for a good hosting site now to post the simulator I built out of HTML5 and javascript.  Hopefully I can find a good site today and get it up and going so people can play around with it.

When you do I'd like to be able to post a link to it on my blog so let us all know as it will be useful! Good luck anyway!

Corrected it.  The backup network was also only on 1 nic :smileysilly:  sorry about that everyone.  I also have seemed to of losted the source file so when I get a chance I will rebuild it and post a cleaner version.

Nice one - as a further enhancement you could look to do dotted lines to detail what's a standby nic (if required) and give an indication as to the load balancing policy you set. Most likely Originating Port ID but that can be up to you sir!

Also if anyone knows a good hosting site to host a website where Java / HTML5 doesn't have any issues let me know.  The HTML5 simulator is ready for beta version 1.0.  It now has most of the images in for switches, nics, hba's, storage, ect and has the connectors working.  So now you can create any item, drag it around, and connect them.  I'm still playing around with the connector code as it always tries to draw a non straight line which bugs me but it works.  None the less I feel it is in a "workable" enough state for a version 1.0 type of deal so i'm looking for a good place to host it now.  Also this way as I work on it and update it people can follow along with the changes.

It's sound really interesting!! I wait for the first beta to try it , it's a good project. And if is possible help , now I'm a teacher for the VCP-DCV5 in italy , and I like to take the DCD .

Sorry for the recent lack of content guys/girls, been working as on getting the beta up and running.  Between that and my personal time being gobbled up I haven't had much time to create new content.  Will hopefully get back to content creation soon once I get the beta 1.0 simulator up so people can start playing around with it.

Cheers

Okay, so I finally got the simulator up and running, keep in mind there is still A LOT of stuff I have to finish and A LOT of graphical tweaks, but alpha 1.0/beta1.0 whatever you want to call it is up.

www.virtualtiers.net

You can at least follow along and play around with how the mechanics will work.

One of the big things I need to work on is the anchors, many still need to be adjusted or more added to some items ect.

I will make a list of bugs I know of tomorrow and what I will be working first.  After that any issues you find please let me know and I will do my best to fix it.  Keep in mind I'm far from the best coder so this stuff takes me a lot longer then I like it to :smileysilly:  What I usally think is a 1hr job takes me 2-3 hours :smileysilly:

I will also give more of a tutorial tomorrow as well but I'm beat :smileysilly: so here is how the connectors work:

The Anchors will show up as soon as you create a connector and then you just drag from a empty circle to a full circle.

Well that's where its at for now, cheers!

Dear Jason..Thx for your time and effort to create something like that

What I found is the following:
1-) Create/start Over/Undo buttons isn't not in their correct places: check the attached screenshot

2-) You can't connect any item with two or more connectors, i.e. empty circle can only be connected to just one full circle, when full circle can be connected with two connectors: check the following

3-) I wish you can get smaller storage processor :smileygrin:
Thx so much my friend
