My VCAP DCV – Deploy 2018 exam (3V0-21.18) experience !!! Wohhooo I am so excited!!! Rajesh Poojary

I am so so excited to tell you guys that after 3 months of sleepless night studies and spending  some money on preparing my Home Lab for daily practice.

I had successfully cleared VCAP DCV – Deploy 2018 exam in my first attempt 🙂

So i would like you to share my exam experience as i have given the exam recently… Ahhh the question about the result time taken… Yes it took 4 long weeks to get to know my results. But never mind i am happy with my result 😉

I had started preparation for the exam 3 months back and i had sleepless nights during this period. I did spend around 3-4 hours and sometime more than that to complete all the study guide given in Exam Blue Print, also spending time on labs.

Exam has 17 questions which are all lab scenarios and if you are working in deployment and in enterprise environment , it would make exam more easier, but the time management is the key for success during exam.

The Exam is total lab based environment, i would suggest to have a good hands on experience of using VMware HOL (https://labs.hol.vmware.com/HOL/catalogs/) , your exam environment would be totally similar to VMware HOL.

I would suggest whoever is going to give this exam should check the exam sections in exam preparation guide (https://www.vmware.com/education-services/certification/vcap-dcv-deploy-2018-exam.html).

Not everything given in exam blue print will come , but don’t take chance be prepared for everything. Make sure you have completed and checked all the tasks given in exam preparation guide.

I would suggest to have a good hands on experience of VSAN and Availability Management.

While i was searching for VMware HOL labs on vSphere 6.5, most of the labs are replaced by vSphere 6.7. So i decided to prepare my own homelab to test the scenarios. Still if you don’t want to spend money on preparing HomeLab, you can still count on VMware HOL vSphere 6.7.

I followed multiple websites for the study resources and i would like to thank everyone who had shared so much study materials which made to clear the exam successfully.

Please find some of the links which i did referred and helped me highly in scoring.

and many more… Feel free to search as many study resources and go through it.

The Exam lab will have multiple vCenters in linked mode, so while doing any task make sure you are doing it on correct vCenter which is given in exam questions.

If you feel at any point you are not able to find the task or options make sure you recheck the vCenter on which you are doing is the right one.

I would like to repeat this again, during exam Time Management is the key to pass the exam. Read the questions properly and if you feel that specific question is time consuming or while doing any task given in exam , if you feel that this gonna take some time. I would suggest you to skip that question and go ahead for next one which you feel you can complete it quickly.

You can always come back and do the question which you had skipped.

Even though i tried to make all the time management, still i was not able to attempt couple of questions even though i was aware of the solution.

So i would request you to make the time management the priority, refer the links given above , do as much lab as possible and once go through all the deployment guides and you should be able to clear this exam.

Happy Learning Guys 🙂

Feel free to like, comment and share.

I would be more than happy to reply to your queries.

Deep Dive into the VMware VMotion

What is VMotion in VMware

 

VMotion is VMware technology which allows you to migrate your live running VM server from 1 physical server to another without any downtime, which allows you to have your server service/applications continuously available. This is very much helpful during your planned activity of your physical server without need of any downtime to the VM server which runs on that physical server which hosts these VM servers.

 

VMotion

 

How does VMotion works?

When you do VMotion of VM, the entire state of VM is encapsulated by a set of files stored in shared storage. The filesystem used in VMware i.e. VMFS (VMware file system) allows multiple ESXi servers to access same set of files concurrently.

 

  • Than the active memory and execution state of VM is rapidly transferred over the high speed network. VMware keeps track of on going memory activity during VMotion activity.

 

 

  • Once the entire system state and memory is copied over the network to other ESXi server, VMotion suspends the VM from current host and transfers the remaining active memory activity and resumes it on the target ESXi server. This entire process takes less than 2 seconds on high speed network.

 

  • VM’s network is also virtualized by the underlying ESXI server which ensures VM’s network identity to be preserved. VMotion manages the virtual machine MAC address as part of the VMotion process and once the VM machines is been resumed VMotion pings the network router to make sure it is aware of the new physical location of MAC address. Since the migration of VM with VMotion preserves the precise execution state, the network state and identity and this results in zero downtime.

 

Hence even users who are continuously working on this VM servers doesn’t seems to see any difference even though at background it is been migrated from one physical ESXI server to another ESXi server.

So this is how VMotion works at the backend.

VMware vSphere 6 Awesome Features – Rajesh Poojary

VMware had always given the best in features , but we were looking for some more features from VMware and here it comes  with vSphere 6 🙂

I have listed few features hope you will love these to know.

vSphere 6 Features and Enhancements:

1)      VMware cluster now supports up to 64 nodes in cluster and 8,000 VM’s.

2)       ESXi Hosts now supports up to : 1000 VM’s ,12 TB RAM , 480 CPU’s and 64 TB datastores.

3)      VM’s hosted now supports up to 4TB vRAM and 128 vCPU’s.

4)      vSphere Fault Tolerance: Here comes the long awaited features which can save lots of engineer by doing extra hours of work and can help mission critical applications to keep always up.

a)      Now FT supports up to 4 vCPU’s and 64 GB RAM.

b)      Earlier versions had limitations of not been able to take snapshots of FT enabled VM’s, this limitation has now been removed and Snapshot is possible of the FT enabled VM’s in vSphere 6, thereby enabling some of the VM backup software’s which relies on Snaphot’s to work  FT enabled VM’s.

c)       In earlier version FT VM’s should reside in same shared storage and using the same disk, but in vSphere 6, Primary and Secondary VM has it’s own .VMX and own .VMDK files, which can be placed in different datastores and are in continuously sync with each other thereby reducing performance issues also.
