Basic VMware Interview Questions

These commonly asked VMware Interview Questions will help you answer your upcoming interview confidently and land your dream job.

1. What is VMware?

VMware is a virtualization technology-based software tool used to test various software virtually by making a virtual operating system. It is like using a different operating system simultaneously as your current OS. It develops virtualization software, which means creating an abstraction layer over computer hardware that allows the hardware elements of a single computer to be divided into multiple virtual computers, also called virtual machines (VMs).

2. What is the reason for using virtual machines instead of original hardware?

VM or Virtual machines allow us to operate multiple operating systems simultaneously from the same piece of hardware. Without virtualization, operating multiple systems like Windows and Linux would require two separate physical units. So it reduces the requirement to invest in additional units by splitting up a physical server into multiple servers.

3. What are the different types of virtualization available?

There are five types of visualizations available, they are:

• Desktop Virtualization.
• Application Virtualization.
• Server Virtualization
• Storage Virtualization.
• Network Virtualization  

4. What is the server software VMware provides us?

VMware provides us with:

• VMware ESX Server,
• VMware ESXi Server, and
• VMware Server.

5. Name some VMware products.

• VMWARE MIRAGE,
• VMWARE PIVOTAL CONTAINER SERVICE,
• VMWARE PHOTON PLATFORM,
• VMWARE THINAPP,
• VMWARE VCLOUD NFV,
• VMWARE VCLOUD NFV OPENSTACK,
• VMWARE VCLOUD SUITE,
• VMWARE VREALIZE.

6. What is desktop virtualization? How does desktop virtualization work?

Desktop virtualization is a technology that simulates a workstation load to access a desktop from a connected device remotely or locally. This separates the desktop environment and associated application software from the physical client device used to access it.

Desktop virtualization works in many ways, but the basic two types of desktop virtualization are based on whether the operating system instance is local or remote.

• Local Desktop Virtualization: It denotes the operating system runs on a client device where all processing and workloads occur on local hardware. This desktop virtualization works when users don’t need a continuous network connection and can meet application computing requirements with local system resources. Although this requires processing to be done locally, you cannot use local desktop virtualization to share VMs or resources across a network to thin clients or mobile devices.

• Remote Desktop Virtualization: Remote desktop virtualization is a commonly used virtualization that operates in a client/server computing environment. It allows users to run operating systems from a server while all user interactions occur on a client device. The result is that IT departments have more centralized control over applications and desktops and can maximize the organization’s investment in IT hardware through remote access to shared computing resources.

7. What is network virtualization?

In virtualization technology, network virtualization is the process of combining network resources and network functionality into a single software-based administrative entity which is called a virtual network. It can combine multiple physical networks into one virtual software-based network, or it can divide one physical network into separate independent virtual networks.

8. Explain memory and storage virtualization?

Memory virtualization is the process of creating a memory pool by aggregating the resources of Random Access Memory (RAM) from individual systems in the data centre.

Storage virtualization is a process of taking information about all of the storage hardware resources on storage area networks. Logically this can be used to combine hardware resources from different networks and data centers.

9. What are the components of VMware infrastructure?

The major components of VMware infrastructure are:

• VMware ESX Server
• VirtualCenter Server
• VMware Infrastructure Client (VI Client)
• VMware Infrastructure Web Access (VI Web Access) 
• VMware Virtual Machine File System (VMFS)
• VMware Virtual Symmetric Multi-Processing (SMP)
• VMware VMotion and VMware Storage VMotion
• VMware High Availability (HA)
• VMware Distributed Resource Scheduler (DRS)
• VMware Consolidated Backup (Consolidated Backup) 
• VMware Infrastructure SDK

10. What is the requirement for running ESXi in the BIOS of the server?

Running ESXi in the BIOS requires the NX/XD bit to be enabled for the CPU in the BIOS in order to ensure the smooth installation of the software programs.

11. What does ESXi stand for?

ESXi stands for ESX Integrated.

VMware ESXi is a type-1, enterprise-class hypervisor which easily installs on to your server and divides itself into multiple virtual machines. It isn’t a software application, although it includes and integrates vital OS components, such as a kernel.

12. What is VMKernel? What is the VMkernel port used for?

The VMkernel is the interface between virtual machines (VMs) and the physical hardware of the system. The responsibility of VMkernel is scheduling CPUs, allocating memory and providing other hardware abstraction with other operating systems (OS) services.

Virtual machines cannot communicate with the ESXi server without VMKernel, so that’s why it’s very important for VMs.

VMkernel port, also called VMkernel adapter, is a type of VMkernel network interface that works as a service provider used by the ESXi host to communicate with the VMware-based infrastructure. These adapters or ports are created according to the type of services required by vMotion, Fault Tolerance, Management or perhaps vSAN etc.

13. What is VMotion? Why is it used?

VMotion could also be a key enabling technology for creating the dynamic, automated, and self-optimizing data centre.

We used VMware VMotion because it enables the live migration of running virtual machines from one physical server to a special one with zero downtime, continuous service availability, and complete transaction integrity.

14. What is Port-group?

VM port groups are how we will create logical rules round the virtual ports that are made available to VMs. It’s common to make a port group for every VLAN and network subnet that you simply want to present to your VMs.

15. What is vSwitch in VMware?

vSwitch is the software-based virtual networking switch used to connect virtual machines to the ESXi host & it also provides the connectivity between the virtual machines on that virtual switch. vSphere Standard Switch is referred to as vSwitch. Each ESXi host requires its own vSwitch.

16. How does vMotion work in the background?

The Virtual Machine Memory state is copied over the Vmotion Network from the source Host to the Target Host. Users still access the virtual machine and potentially update memory pages. A list of modified pages in memory is kept during a memory Bitmap on the source host.

17. What happens if VMotion fails?

VMotion will fail if the target host does not have enough memory to satisfy the reservation of the virtual machine. If you want to fix this, migrate the virtual machine to another ESXi host that can provide the guaranteed memory for the VM or reduce the memory reservation of the virtual machine.

18. What is the hypervisor and its types?

A hypervisor may be a virtualization layer that permits multiple operating systems to share one hardware host. Each operating system or Virtual Machine is allocated physical resources such as memory, CPU, storage etc by the host. There are two types of hypervisors.

• Hosted hypervisor – works as application i.e. VMware Workstation
• Bare-metal – is virtualization software i.e. VMvisor, Hyper-V which is installed directly onto the hardware and controls all physical resources.

19. We have got tons of features like VMotion, DRS, SMP, etc, but why do we like HA?

We’d like this because we want our services running without interruption. Assume like, for a couple of reasons if anyone of the ESX server within the cluster goes down suddenly, what happens to the virtual machines which are running thereon particular server? Do they continue to run or go down? Yes, they also go down. But with the help of VMware HA, these VM’s are often restarted immediately on the other ESX servers within an equivalent cluster. But here, you’ll get a downtime of 5 –10 mins because a server crash is an unexpected thing.

Intermediate VMware Interview Questions

If you are someone who already has a basic understanding of VMware, this section is helpful for you as it covers the intermediate VMware interview questions.

20. What architecture changes were seen between ESXi 4.1 and 5.0?

vSphere 5.0 involves a replacement HA architecture. HA has been rewritten from the bottom up to shed a number of those constraints that were enforced by AAM. HA, as a neighbourhood of 5.0, also mentioned as FDM (fault domain manager), introduces less complexity and better resiliency. From a UI perspective, not tons have changed, but there are tons under the covers that have changed. Though no more primary/secondary node concept as stated but a master/slave concept with an automated election process.

21. Is HA dependent on Vmware vCenter Server?

Yes. But only during the initial installation and configuration.

22. What is VM Monitoring status?

HA will usually monitor ESX hosts and reboot the virtual machine within the failed hosts within the opposite host within the cluster just in case of host isolation. Still, I want the HA to monitor Virtual machine failures also. Here the feature called VM monitoring status as a neighbourhood of HA settings.VM monitoring would restart the virtual machine if the VMware tools heartbeat didn’t receive within the specified time using Monitoring sensitivity.

23. What is VMware vSphere API and vSphere SDK?

VMware vSphere API may be a set of interfaces for managing vSphere. You can use the API to try to do most of the items the vSphere Client can do. The API is defined as SOAP Web Services with WSDL. The vSphere SDK could also be a group of libraries that support vSphere API, also as tools and samples that assist your development efforts. The vSphere SDK is additionally referred to as VI SDK, vCenter SDK, ESX SDK, etc. In most discussions, the vSphere API and vSphere SDK are used interchangeably.

24. What’s VMFS?

VMFS may be a block-level, high-performance clustered filing system for virtualization. It is often shared between multiple ESXi hosts or VMs and may simultaneously write and read data to and from one storage location.

25. What advantages does VMware filing system provide over the utilization of traditional file systems?

The advantages of the VMware filing system over the utilization of a traditional filing system are that the structure of VMFS makes it possible to store VM files in a single folder and simplifies VM administration. Traditional file systems authorize only one server to get read/write access to a storage resource. This guarantees that a VM works with only one ESXi server at a time.

26. What’s a VMware Data-store?

Data-stores are the storage containers for files. Generally, data-stores hide the specifics of every memory device and supply a consistent model for storing VM files. Data-stores are wont to hold virtual machine files, templates, ISO images etc.

27. What’s the difference between NFS and VMFS data-stores?

NFS may be a file-level filing system, while VMFS may be a block-level filing system. Once we create a VMFS Data-store, the VMFS filing system is made by the vSphere, but the NFS filing system is on the Storage side and is merely mounted and features a shared folder on the vSphere.

28. What’s iSCSI in VMware?

iSCSI may be a protocol which uses the TCP to move SCSI commands and also enables the utilization of the prevailing TCP/IP networking infrastructure as a cargo area Network.

29. What’s the default port employed by iSCSI during a VMware vSphere environment?

In a VMware vSphere environment, iSCSI uses TCP ports 860 and 3260 with higher-level names wont to address the objects within the protocol.

30. What’s multipathing in vmware?

In VMware, multipathing may be a process that permits you to employ quite one physical path that transfers data between the host and an auxiliary storage device. During a failure of any element within the SAN network, like a switch, adapter, or cable, ESXi can switch to a different physical path that doesn’t use the failed component.

31. What’s FCoE protocol?

Fibre Channel over Ethernet or FCoE may be a transport standard that takes Fibre Channel frames and encapsulates them within an enhanced Ethernet network. FCoE retains Fibre Channel upper-level protocol features like flow control and data integrity checking but not its cables and interfaces.

32. What’s the difference between FC and FCoE?

FCOE maps Fiber channels over full duplex Ethernet networks based on IEEE 802.3 standard. And therefore the other hand, Fiber Channel or FC may be a serial data transfer protocol and standard for high-speed enterprise-grade storage networking. It accelerates to 128 Gbps and delivers storage data over fast optical networks.

33. How does VMware measure IOPS?

VMware measures IOPs by these two formulas:

A. IOPS = 1/(Avg. Latency + Avg. Seek)(ms) (per Disk )

B. Total IOPS = IOPS * Total number of Disks.

34. What’s IOPS in VMware?

IOPS stands for Input/output Operations per Second and may be a common performance measurement to benchmark memory devices like hard disc drives, solid state drives and cargo area networks.

35. What’s the utilization of snapshots in VMware?

The VMware snapshot is used to preserve the state and data of the Virtual machine at the present point in time, so once you are done testing, you’ll quickly revert the VM back to the desired state. In VMware, VMware snapshots are easy and quick thanks to saving the state of a virtual machine before you test a software update, patch or other change.

36. What percentage sorts of snapshots are there in VMware?

As the perspective of files VMware snapshot are often four types:

1. Delta disk files
2. Flat file
3. Database file
4. Memory file

37. Are you able to restore a VM from a snapshot?

Yes, one can restore a snapshot in VMware by using the Revert and attend commands.

38. What’s ALUA storage?

ALUA stands for Asymmetric Logical Unit Access. ALUA may be a specific memory device capable of servicing I/O to a given LUN on two different storage processors but unevenly. Using ALUA, I/O to a given LUN are often sent to available ports on any of the SPs within the storage array.

39. What’s NUMA in VMware?

The full sort of NUMA is Non-uniform access. It’s a memory design utilized in multiprocessing, where the access time depends on the memory location relative to the processor. The biggest disadvantage is that the access of the CPU is usually the fastest when the CPU can access its local memory.

40. How do I enable NUMA in VMware?

There are thanks to enable NUMA in VMware which is:

• Configure one virtual machine to use hyper-threading with NUMA, add NUMA and VCPU.
• Click on the VM option then select Edit Settings.
• Now configure all virtual machines to use hyper-threading with NUMA. Add numa then configure PreferHT=1 for per-host advanced configuration file.

41. What’s vNUMA or Virtual NUMA?

vNUMA or virtual non-uniform access may be an access optimization technique for VMware virtual machines (VMs), which helps prevent memory-bandwidth bottlenecks. Virtual NUMA is particularly useful with large, multiple VMs during a vApp or high-performance virtual machines.

42. What’s a LUN in VMware? What’s the complete sort of LUN?

LUN stands for Logical Unit Number. LUN could also be a logical section of storage. A LUN is often one disk or multiple disks, and it can also be allocated from a disk pool or disk volume relying on the storage vendor’s terminology. A data store could also be a representation VMware uses for an area of storage that virtual machines can reside on.

43. Why is RDM employed in VMware?

RDM allows Virtual machines to bypass VMFS. VMware’s default storage management interface and access the memory device directly. In this manner, an RDM acts as a proxy for a raw LUN residing during a VMFS volume. RDM or Raw Device Mapping may be a mapping file that maps a LUN on to a VM.

44. What’s the difference between RDM and VMDK?

RDM is additionally referred to as a pass-through disk and may be a mapping file that acts as a proxy for a physical device like a LUN. On the opposite side, VMDK may be a file that appears as an uncompromising drive to the guest OS. Fundamentally it’s a virtual disk drive.

45. How to add RDM to VMware?

First, you’ve got to create the RDM pointer file, then attach the RDM to a virtual machine using the vSphere Client; Right-click the virtual machine you would like to feature an RDM disk, Click Edit Settings, Click Add, Select hard disc, Select Use an existing virtual disk.

46. What’s the first feature of VMware vSAN?

The primary feature of VMware vSAN is its work with VM storage policies to support a VM-centric approach to storage management.

47. What’s the difference between SAN and vSAN?

SAN leverages storage protocols like FCP and iSCSI while vSAN only works with ESXi hosts. Within the case of SAN, storage administrators are required to pre-allocate storage on different systems although vSAN automatically converts local storage resources into one storage pool.

48. What’s NAS in VMware?

The NAS or network-attached storage transport mode enables the virtual server agent proxy computer to read data directly from the network digital computer (NFS) without browsing an ESX host or transferring data over the local area network.

49. What’s vSphere replication NFC?

vSphere replication NFC is that the replication traffic was sent and received using the management interfaces of ESXi and VRA appliances. NFC (Network File Copy) traffic is employed to repeat VM replication data from the vSphere Replication Server appliance at the target site to the destination datastores.

50. What’s VMware VAAI?

VMware VAAI is hardware acceleration or hardware offload APIs which are a group of APIs to enable communication between VMware vSphere ESXi hosts and storage devices.

51. How do I know if VAAI is enabled?

To enabled VAAI steps are following,

1. In the vSphere Client inventory panel, click the host.
2. Click the Configuration tab, then click Advanced Settings under Software.
3. Check that these options are set to 1 (enabled).

52. What’s NFS in VMware?

NFS generally referred to as Network File Systems, may be file-level storage allocated by shared storage. Its network-attached storage will be shared through a cluster in vSphere. It also allows a user on a computer to access files over a network similar to local storage.

53. What’s the default number of ports configured with the virtual switch?

The default number of ports configured with the virtual switch is 128 ports.

54. What’s vDS in VMware?

The full form is vDS is VMware vSphere Distributed Switch which provides a centralized interface from which you’ll configure, monitor and administer virtual machine access switching for the whole data center. And it also provides support for advanced VMware vSphere networking features.

55. What’s a vSphere client?

The vSphere Client is application software that permits the management of a vSphere installation. The vSphere Client provides an administrator with access to the key functions of vSphere without the necessity to access a vSphere server directly.

56. What’s the max number of virtual machines per host?

Maximum number of virtual machines per host is 100.

57. What’s a host and cluster in VMware?

A Host is the virtual representation of the computing and memory resources of a physical machine running ESX Server, and a cluster may be a group of hosts.

58. What’s VMware auto deploy?

Auto Deploy is a process of VMware that stores the knowledge for the ESXi hosts to be provisioned in several locations. Information about the situation of image profiles and host profiles is initially laid out in the principles that map machines to image profiles and host profiles.

59. How does one automate a VM deployment in VMware?

Steps to automate a VM deployment in VMware:

1. Enter the vCenter IP address, username and password.
2. Select your vCenter platform.
3. Enter the registration details, and therefore the new specification name.
4. Enter the administrator password.

60. What are the 2 reasons why a virtual machine might fail to power on?

The two reasons for a virtual machine might fail to power on:

1. The virtual machine is running on an ESXi host which has an expired license.
2. The virtual machine is running on a data-store which has insufficient disc space for the .vswp file.

61. What’s VMware VUM?

VUM, also called VMware vSphere Update Manager, may be a tool that gives a patch management framework for VMware vSphere. IT administrators use VUM to patch and upgrade VMware ESXi hosts, VMware Tool, virtual hardware for virtual machines, and appliances.

62. What’s an appliance in VMware?

68. Which cloud service does VMware vCloud air provide?

vCloud Air provides three Infrastructure as a Service(IaaS) subscription service types- dedicated cloud, virtual private cloud, and disaster recovery.

69. What’s VMware VADP?

VMware VADP may be a VMware vStorage API that backs up and restores vSphere virtual machines. VADP replaces the VMware Consolidated Backup (VCB) framework, this offloads backup processing from ESX hosts and allows each ESX host to run more VMs.

70. What does MOB in VMware stand for?

MOB in VMware stands for Managed Object Browser.

71. How do I disable Storage DRS for the Data-store?

The steps are:

1. Browse to the data-store cluster within the vsphere Client.
2. Click the Configure tab and click on Services.
3. Select Storage DRS and click on Edit.
4. Select activate vSphere DRS and click on OK.

An optional step is to disable only I/O-related functions of Storage DRS, leaving space-related controls enabled then perform the subsequent steps.

72. What do you mean by clone & template in VMware? What is the difference between the two? 

Clone VMware: Clone virtual machines are the identical copy of the parent virtual machine; however the clone virtual machine and parent virtual machine will have different MAC addresses and UUIDs. Any changes done on a cloned virtual machine will not affect the parent virtual machine and vice-versa.

Template VMware: Template VMware the master copy or golden image of virtual machine that is used to provision virtual machines. This image can be later used to clone multiple virtual machines.

Clone VMware	Template VMware
Create the exact copy of the parent virtual machine that can work independently	It is a master copy of a VM with basic configuration and can’t work independently
The cloned VM can’t be converted back to the parent VM or original VM	Template VMware can be converted back to virtual machine and updated the latest configuration before converting back to template for future VM deployment
For deploying large numbers of VM it is not recommended	For deploying large numbers of VM it is recommended
Clone VM can we turned on/off	Template can’t be turned on/off or edit it
Powered on VM can we cloned	Powered on VM can’t be used to create templates

73. What are VMware HA and VMware FT? What is the difference between the two?

VMware HA: VMware HA (High Availability) works on cluster level. By pooling virtual machines and hosts resides into a cluster. Virtual machines running on failed hosts are forced to restart on alternate hosts. 

VMware FT: Vmware FT (Fault Tolerance) works on VM Level. In this a secondary virtual machine is created and maintained as identical to the primary virtual machine and it can be replaced when ESXi hosts fail to provide continuous availability of virtual machines. It is a complete copy of a virtual machine including storage, computation and memory.

VMware HA	VMware FT
VMware HA is enabled per cluster	VMware FT is enabled per Virtual Machine
VMware HA works on cluster level	VMware FT works on VM level
In case of failure the HA system will restart and power on VM on another host	In case of failure the FT system will start secondary host in case the lost of primary host by providing fast backup and continuous availability and reduces downtime

74. How many CPUs can be used for a VM in FT in vSphere 7.0?

In VMware vSphere 7.0, we can use up to 8 vCPUs with VMware vSphere Enterprise Plus license. 

75. Explain Fault Tolerance logging traffic.

Fault tolerance logging traffic is considered to be the second network requirement. For syncing the data between primary VMs and secondary VMs fault tolerance applies FT logging.

76. Differentiate between vSphere and vCenter.

vSphere	vCenter
vSphere is a complete infrastructure for virtualization	vCenter is a centralized and extensible platform
It is complete infrastructure for virtualization	It is a centralized and extensible platform
It allows IT team to build reliable and resilient infrastructure	It allows IT team to automate and deliver a virtual infrastructure
The initial release of vSphere was April 21, 2009	The initial release of vCenter was December 5, 2003

77. Will FT work if the vCenter server goes down?

Fault tolerance does not require vCenter to be online once configured, due to this no fault tolerance between primary and secondary will occur when vCenter is down.

78. What do you understand about Promiscuous mode?

Promiscuous mode is used for monitoring traffic. In the Promiscuous mode, all the network data packets can be viewed and accessed by all the network adapters operating in this mode. It is a network security, monitoring, and administration method that allows any network adapter configured on a host system to access all network data packets.

79. What do you mean by cold and hot migration?

Cold Migration: In this migration, the powered-off VM, along with its configuration and data, is migrated from one host to another host. The VMs can be migrated manually, or one can set up scheduled tasks to perform this migration.

Hot Migration: In this migration, the powered-on VM is migrated from one host to another. This is also known as live migration because there is no need to shut down the virtual machine.

80. What is the difference between virtual desktop and remote desktop?

Remote Desktop: The remote desktop program allows a computer that is located at a different location and interacts with the desktop as if they are accessing them physically, sitting in front of that device. Its solution is best for people who want to access their computers if they are away from their usual workplace. Also, it is beneficial for the technician who wants to fix any issues remotely by taking the remote console of that system.

Virtual Desktop: Virtual Desktop and Remote Desktops offer similar functionality – under the surface, there are a few significant differences. Virtual desktops provide a pre-configured image of operating systems or applications – separate from the device used to access them. Over the internet, any endpoint device – be it a laptop, tablet, or smartphone can be used to access the virtual desktop. 

81. How can I differentiate between virtual machine port groups and VMkernel ports?

The VMKernel port provides connectivity to the host, and it handles the traffic like vMotion, Fault Tolerance traffic, and management. The IP address is assigned to the Virtual Kernel Adapter (VMK) of the VMKernel port group. The Virtual machines are connected to the VM port group.

One of the important differences is that a Virtual Machine port group is just passing your garden variety virtual machine traffic, and a VMKernel port group is passing traffic specific to VMware vSphere.

82. What’s the difference between VMFS and NFS?

VMFS (Virtual Machine File System): VMFS is a block-level file system that is used to store virtual machine files. In vSphere 6.0, it can also store large files up to 64TB in size. 

NFS (Network File System): NFS is a distributed file system protocol that was first developed by Sun Microsystems in 1984. It has a client/server architecture, which contains a client program, server program, and protocol that helps to communicate between the client and the server. It helps the user to access the data and files easily over the network.   

83. What do you understand about RDM?

The Raw Device Mapping (RDM) files are contained in VMFS and act as proxies for raw physical devices. This helps virtual machines access logical unit numbers (LUNs) directly. The RDM contains metadata used for managing and redirecting disk access to the physical device.
