VCAP-DTMmmmmm. After securing the VCP-DTM for version 6 and getting the pass results in for the version 7 DTM Beta, my sniper target is set for the VCAP-DTM’s. Maybe I should cut down on Battlefield 1 a bit ;). Anyhow…..
As the title of this post suggests, first up the deploy exam. Version 6 as version 7 VCAP’s are not yet out. Deploy is possibly the one that fits my person a bit lesser than the design part, but it is always good to have the “weakest” out-of-the-way the fastest. But there is no requirement that you should do deploy first, if you want design out of the way first go with that one.
With the VCAPs I have attempted and by hearing of the experience from those that have tried, next to actually knowing what you’re doing time management is (still) the key of securing the VCAPs. I think the actually knowing bit is pretty okay for most that will attempt this exam. Maybe some bit of practice in the Mirage parts for myself. And that is exactly needed for time management. Know your weak(est) and strong(est) points in the list of exam objectives. And next to that, with time management comes drill drill drill. And where better to drill than in a lab. Or to put it in other words, you will need a lab for the deploy!
Now where are we with DTM?
Exam Topics aka Objectives
You will find a lot of blog post explaining how to prepare and going through all the exam objectives. And I do mean a lot. I am not putting in a how to study for that objective in this blog post. Use your google-fu for that.
The exam objectives for this post are important for what components you need to have in your lab.
On the mylearn page of the exam the exam topics are in expendable sections and clickable white papers, documents and such to prepare. Just go to: https://mylearn.vmware.com/mgrReg/plan.cfm?plan=88780&ui=www_cert. I haven’t seen an other PDF exam blueprint document for this exam on the VMware site.
Some bloggers will offer their packages of collected set of documents for preparation. One for example is offering theirs on: http://www.virtuallyvirtuoso.com/vcap6-dtm/.
VCAP6-DTM Component Versions
When going through the VCAP6 objectives we will need the following components and their versions of the Horizon Suite:
- Horizon 6.2 Components: CPA, Connection Server, Security Server and Composer.
- Pools: Linked clone PCoIP pool (Windows 7), RDSH Farm (W2K8R2/W2K12R2), Application Pools (Evernote). Reference machine Windows 7 and RDS version for ThinApp and App Volumes.
- vSphere and vSAN 6.0: vSphere HA/DRS Cluster resources for management and pools. VSAN Storage.
- Identity Management: vIDM 2.4.1
- Application Layer Management: App Volumes 2.9, ThinApp 5, version 5.1.1.
- Image Management: Mirage 5.4
- Endpoints: Web-based, Horizon Clients, Kiosk.
- Operations Management: vROPS for Horizon version 6.1.0.
- Supporting Infrastructure/Tools: Active Directory (DNS,DHCP), GPO, MSSQL Database server, VMware OS Optimization Tool (OSOT) with support for Windows 7/8, File Services ThinApps Repository, syslog and Windows 2012R2 Jump Host.
The easiest way to get the VMware bits is to go to the Horizon Enterprise edition download on my.vmware.com and select the version 6.2. You need evaluation or an entitled my VMware user to access those. You can use this link for your bits: https://my.vmware.com/group/vmware/info?slug=desktop_end_user_computing/vmware_horizon/6_2.
Download OSOT here: https://labs.vmware.com/flings/vmware-os-optimization-tool.
Strange, wondering why they did not put Access Point or UEM in the exam objectives. Access Point for example is designed to be deployed with Horizon version 6.2. A well less bits to put in the lab.
For supporting Infrastructure and tools, and client versions it is up to you, at least put in the supporting versions.
Study Lab options
The deploy part is a lab based exam. Hands-on experience with the Horizon suite is crucial for success. Not everyone has a home lab, cloud lab credits or have enough resources on their notebooks to put in all the resource hungry Horizon suite components, you can use a combination of lab options in your exam preparations. Don’t forget the Horizon suite versions that are used in the VCAP version and components in your study lab. Practice with the right version, or know what have been changed between versions what takes a little more preparation time.
Get command line experience in practicing with vdmadmin, lvmutil, client and dct command line options, web interface locations, RDP to servers, SSH to appliance and log / config file locations.
This can be a lab in a notebook and to some people having a home lab that are offering more services and resources than a small country uses in a decade. Home labs are excellent for build and break your own. You will not have any permissions issues. Downside mostly are the resources required.
Again this provides good experience in build and break your own. Accessible from anywhere. Downside mostly are the resources required and the costs that are involved.
If you are a 2017 vExpert like me, Ravello (https://www.ravellosystems.com/go/vexpert/lab-service-description) still offers 1000 CPU hours per month to vExperts. Build your lab, configure an application start-up and stop procedure and set your lab to stop after practicing. For example put in 2:00 hours of studying and after that your lab will shut down and no CPU cycles will be wasted.
You can even simulate the exam lab speed and put your lab in a cost optimized far away cloud provider location. Pretty good for the time management preparations.
Downside for Ravello is the support of VMware OVA appliance deployment, there are some tips and tricks needed to get appliances uploaded to Ravello. Or optionally go for Windows components or nested deployments.
I’m currently building my lab in here: (yes status stopped in screenshot and Windows 10 is my client)
Hands on Labs.
VMware Hands on Labs are an excellent place to practice with a whole scale of VMware products. Use the manual to be guided through the labs, or just click it away and go on your own. Choose from the mobility labs for example: http://labs.hol.vmware.com/HOL/catalogs/catalog/125.
I personally use HOL-1751-MBL-1-HOL a lot. Downside no composer as Horizon 7 instant clones is used, version mismatch with exam lab and no vROPS for Horizon. For vROPS for Horizon I use Testdrive. You also aren’t administrator on Windows hosts and there is no Internet connection to get some missing piece in.
You start with 1hr:30min, and you can extend the lab time up to 8 times with one hours. Topping up to 9hr:30minutes of lab time per enrollment. Amazing discovery Mike!
VMware Testdrive is the EUC demo environment. Need to show the customer some part they are missing or need some extra’s to make your point, open up a testdrive for the customer and let them show see it. As a superuser I also misuse it to work on some vROPS for Horizon parts. You are admin in vROPS so testing a metric set for a dashboard or showing policies without breaking the customers vROPS environment. The rest of the components are limited in what you can do and practice over there. But that wasn’t the use case of Testdrive in the first place.
Time management studying for the exam
Time management starts with studying. Plan your exam date and schedule your exam up front. Take enough time to prepare and work through the objectives. How much depends on your own strong and weak points. But do schedule the exam, else you will have no target to work to and that VCAP-DTM will be a never-ending story.
Time management throughout the Exam Lab
You can navigate through the lab exercise scenario’s. Go through the objectives. Use you notepad to put an order for easy or though ones. Get the easy one’s done and out-of-the-way. Labs that require deployments, captures, synchronisation or otherwise take time to finish, start-up those actions and go to the next. Don’t waste time watching progress bars……
There are dependencies between questions and skipping a part of a question because you are waiting for a deployment can be tricky for your mind if your also working through the scenario. You have to make sure you come back to that incomplete task and finish it.
Test Center Check
If you have the opportunity and have multiple options for test centers in your friendly neighborhood, be sure to check out what lab setup they have. I know where I would go if I had to choose between test centers that have 21″ or 17″ screens. Or ask on twitter or Reddit if someone has experience with the test center.
– Happy prepping your exam!
