Technical interviews assess the professional’s hands-on experience and technical expertise. A few of the interview questions on VMware Technology typically asked for an intermediate fresher candidate have been discussed here along with its answers. Hope these basic technical Q&As of an interview keeps you calm as you wait for the turn to get interviewed. VMware, being the virtualization leader needs no introduction. It is a known fact that it provides solutions in the field of Data center virtualization   Network virtualization

  2. www.mercurysolutions.co  Desktop virtualization and  Cloud The specialty of VMware is that it updates with the evolving technology. The versions represent the new add-ons of the technology. And organizations have realized the potential of going virtual and is in the constant hunt for subject matter experts. So, it’s high time for you to get ready for the interview and grab the opportunity. A few common VMware Interview questions and its answers in 2018 have been discussed here for your reference studies that would help you to crack the technical round. 1. What favored you to opt for Virtualization? 1. What favored you to opt for Virtualization? Virtualization refers to the creation of virtual machines and its remote management. The virtual versions of the physical components includes the storage devices, network devices, servers, and, etc. With virtualization, one is able to run multiple virtual machines on a single physical machine. The main benefits of implementing virtualization include: More than 50% of the total investment cost is reduced   Facilitates the operation of multiple operating systems on one virtual platform  Wards-off the heavy hardware dependency for running the application  Leads to high productivity with only a few servers  Cuts the need of physical environment [data center space] to a greater extent  Minimizes or eliminates the downtime completely  Increases the productivity and agility of the IT  Enhances the efficiency and responsiveness  Provisioning of resources and applications are made faster  Disaster recovery is faster leading to business continuity

  3. www.mercurysolutions.co 2. Well, you said the creation of virtual machine? How do you 2. Well, you said the creation of virtual machine? How do you convert a physical machine into a virtual machine? convert a physical machine into a virtual machine? The physical machine could be converted to a virtual machine in simple three steps. They are Installation of an agent to the physical machine   Installation of VI client with converter plug-in  A server placed to import or export the virtual machines 3. What are the different types of virtualization? 3. What are the different types of virtualization? The main types of virtualization include Server, Network, Storage, Application, and Desktop. Application Virtualization: It increases the mobility of the applications and facilitates migration of the VMs with lesser downtime.   Desktop Virtualization: It is the virtualization of the desktop so as to reduce the cost and increase of the service.  Network Virtualization: It completely reflects the physical network as the software-defined network.  Server Virtualization: The multiple operating systems and the physical server could be run on the single server.  Storage Virtualization: It gives the abstraction layer for the resources of physical storage to get optimized in virtual deployment. 4. What is cold and hot migration? 4. What is cold and hot migration? Migration in VMware refers to the process of transferring the virtual machine from one host or storage location to the other one. It is an added advantage for

  4. www.mercurysolutions.co using the virtual machines. The migration could be either hot or cold. Hot migration refers to the transfer of the operating system and the applications to the physical machines from the virtual machines while the OS or the applications still in its running stage. Whereas, cold migration involves the suspended virtual machines or turned-off migration. The disks are moved from one data store to another. 5. What are VMware tools? 5. What are VMware tools? VMware tools represent a suite of utilities which enhance the performance of the virtual machines’ guest operating system and the VM management. 6. How do you use the VMware tool? 6. How do you use the VMware tool? Installation of the VMware tool eliminates or enhances the issues like Inadequate color depth   Restricted mouse movement  Low video resolution  Incorrect Network display speed  Inability to drag-n-drop files or copy-paste  Syn the time of host and the guest operating system  Support the guest-bound calls  Ability to take quiesced snapshots of the guest OS 7. How do you differentiate a clone from that of a template? 7. How do you differentiate a clone from that of a template? Sr. NO Clone Template

  5. www.mercurysolutions.co Clone forms the exact copy of the running VM It is the baseline image for the virtual machine having predefined configurations 1 Cloning creates the exact copy with same configurations and no additional settings Creation of template is creating a master image from where multiple virtual machines could be deployed 2 A clone is created by right- clicking the running virtual machine and click clone A template is created by converting/cloning a virtual machine or cloning another template 3 Best suited for test and development environments Best suited for the production environment 4 Not suitable for virtual machine mass deployment Suitable for virtual machine mass deployment 5 6 Clone is not converted back Template is converted back Templates could not be created while powered on 7 Clones could be created while powered on 8. What is a hypervisor? 8. What is a hypervisor? A hypervisor or the virtual machine monitor is nothing but the computer firmware, hardware, or the software which creates and runs the virtual machines. The computer on which the hypervisor runs is called the host machine and the virtual machine is called the guest machine. They are mainly of two types: Type 1 or the Native/Bare metal Hypervisor: It runs directly on the hardware of the host and manage the hardware and guest operating systems. Apart from VMware ESX and ESXi, other hypervisor includes Microsoft hypervisor, Citrix XenServer, Oracle VM, and, etc.

  6. www.mercurysolutions.co Type 2 or the Hosted Hypervisor: It runs on the conventional operational system. Apart from VMware Workstation, VMware Server, other hypervisors include Microsoft Virtual PC, Oracle VM Virtualbox, Red Hat Enterprise virtualization, and, etc. 9. What 9. What is Fault Tolerance? is Fault Tolerance? VMware Fault Tolerance delivers continuous availability for the virtual machines even in an event of failover condition by creating and maintaining the secondary VM that is identical to the primary VM and is made available continuously. Fault Tolerance [FT] could be enabled for most of the virtual machines. 10. How do you secure the vCenter server and the users? 10. How do you secure the vCenter server and the users? By authenticating the vCenter with the Active Directory, one can assign specific roles to the users and thus manage the virtual environment efficiently and in a secure manner. 11. What is Virtual Desktop Infrastructure? 11. What is Virtual Desktop Infrastructure? Virtual Desktop Infrastructure [VDI] hosts the desktop operating system on the centralized server in a data center. It is also referred as server-based computing as it is the variation on the client-server computing model. The end user gets connected to their desktop by using the thin client. Moreover, the end user may get connected to the desktop by using the VMware Horizon view.

  7. www.mercurysolutions.co VMware is for easy access? 12. How do you justify that 12. How do you justify that VMware is for easy access? VMware comes with several features that make the user easy for access and maintain. A few of the features include:  Easy to use wizard for settings configuration  Web browser interface  Tools to create and maintain hosts  Easy maintenance of virtual machines  Configure VMware settings with easy graphics 13. What is the use of VMware Workstation? 13. What is the use of VMware Workstation?  Facilitates the user to run more than one operating systems on a single system simultaneously  Saves the existing operating system’s configuration in the form of virtual machines  Users may work on different OS even without switching between the OSs. 14. How does virtual machine communicate from one server to 14. How does virtual machine communicate from one server to the other server? the other server? The virtual machine communicates by using a virtual switch [vSwitch] /uplink adaptors. It uses the physical NICs associated with the host server so as to connect the physical and virtual network. 15. What is virtual networking? 15. What is virtual networking? It is the network of virtual machines running on the physical server that are logically connected with each other.

  8. www.mercurysolutions.co Bonus Question: Bonus Question: What are the disadvantages of VMware virtualization platform? What are the disadvantages of VMware virtualization platform? A few of the disadvantages include:  One must have the better understanding of the concept  It requires a huge investment to buy the resources  High-end server is required that increases the cost  Different technologies are required for implementation  System failures compensation is too costly with less reliability I hope you have got a glimpse of the Interview.
