3. VMware Interview Questions
Q1. Can you explain what VMware is and why it is used in the industry? (Virtualization Fundamentals)
VMware is a leading provider of multi-cloud services for all apps, enabling digital innovation with enterprise control. It is widely recognized for its virtualization products, which allow businesses to run multiple virtual machines (VMs) on a single physical machine, and share the resources of that single computer across multiple environments. Different operating systems can run on the same physical hardware, which is a cost-effective way of managing and optimizing the use of hardware resources.
VMware’s virtualization technology is used in the industry for several reasons:
- Resource Optimization: It helps in consolidating servers and saving on hardware costs.
- Isolation: Each VM is isolated from others, which means that if one VM crashes, it doesn’t affect the others.
- Encapsulation: A VM includes a full copy of an operating system, one or more apps, and the necessary binaries and libraries — making it highly portable.
- Hardware Independence: VMs can be easily moved, copied, and assigned to other servers.
- Management and Automation: Improve the efficiency, agility, and responsiveness of IT to business needs.
Q2. Why do you want to work with VMware technologies? (Interest & Motivation)

Q3. How does vSphere High Availability (HA) work? (High Availability & Fault Tolerance)
vSphere High Availability (HA) provides easy-to-use, cost-effective high availability for applications running in virtual machines. In the event of server failure, affected VMs are automatically restarted on other production servers with spare capacity. Here’s a glimpse of how it works:
- Host Failure Detection: HA monitors whether each physical server (host) in a cluster is still running. If a host stops responding, HA treats this as a failure and initiates VM restarts on other hosts.
- VM Monitoring: Besides monitoring the health of servers, HA can also monitor VMs to ensure they’re running properly. If a VM stops responding, HA can reset the VM and get it running again.
- Admission Control: This ensures that sufficient resources are reserved for VM recovery in case of a host failure.
- Network and Datastore Heartbeating: In situations where a host is isolated from the network, HA uses datastore heartbeating to determine if the host should be considered down and its VMs restarted elsewhere.
Q4. Can you describe the differences between vSphere, vCenter, and ESXi? (VMware Product Knowledge)
Here are the primary differences between vSphere, vCenter, and ESXi:
Feature | vSphere | vCenter | ESXi |
---|---|---|---|
Definition | A suite of products and features for server virtualization. | A centralized management platform for vSphere environments. | A bare-metal hypervisor that installs directly onto a server. |
Components | Includes ESXi, vCenter Server, and other components. | Does not include ESXi but manages it. | Does not include vCenter but can be managed by it. |
Purpose | Provides the foundation for a cloud computing architecture. | Provides a single point of control for vSphere environments. | Provides the layer that allows multiple VMs on a single host. |
Functionality | High availability, distributed resource scheduling, etc. | VM management, resource allocation, monitoring, etc. | Runs VMs and manages their resources. |
vSphere is the overall product suite that provides cloud computing virtualization. vCenter is a management application that allows centralized management of vSphere environments. ESXi, on the other hand, is a type 1 hypervisor that runs on the host machine to manage and allocate resources to VMs.
Q5. What is VMotion and how does it work? (VM Migration & DRS)
VMotion, now called vSphere vMotion, is a feature that allows the live migration of running VMs from one physical server to another with zero downtime, continuous service availability, and complete transaction integrity. Here’s how it works:
- Pre-Migration: vSphere vMotion checks if the target host has sufficient resources and is compatible with the virtual machine’s hardware requirements.
- Quiesce and Snapshot: The VM’s memory, current state, and precise execution point are quiesced and snapshoted.
- Transfer: The memory and execution state of the VM are then transferred over a high-speed network to the target ESXi host.
- Switch Over: Once the memory and system state are copied, vSphere vMotion switches the VM network identity and storage to the new host without any noticeable service interruption.
- Clean Up: The original VM on the source host is powered off, and resources are cleaned up.
vSphere vMotion is a key component of VMware’s Distributed Resource Scheduler (DRS), which automatically balances computing workloads with available resources.
Q6. Describe the process of creating a new VM on an ESXi host. (VM Provisioning & Management)
Creating a new VM on an ESXi host involves several steps. Here is a general process:
- Log into vSphere Client: Access your vSphere Client and connect to the vCenter Server or directly to the ESXi host if vCenter is not used.
- New Virtual Machine Wizard: Right-click on the ESXi host in the inventory and select "Create New Virtual Machine" or click on "Create a new virtual machine" from the Actions panel.
- Configuration: Select a configuration type, typically "Custom" for advanced settings or "Typical" for a guided setup with default settings.
- Name and Folder: Enter the name of the virtual machine and select the location (datacenter or folder) where it will be stored.
- Compute Resource: Choose the host or cluster where the VM will run.
- Storage: Select a datastore where the virtual machine files will be stored.
- Compatibility: Choose the virtual machine version that defines the hardware features available to the VM. This should match or be lower than the ESXi host version.
- Guest OS: Choose the guest operating system family and version.
- Customize Hardware: Configure the virtual machine’s hardware, such as CPU, memory, network, and disk size. You can also add additional hardware like GPUs or USB controllers.
- Review and Finish: Review the configuration summary and click "Finish" to provision the VM. The VM files will be created on the datastore and the VM will be powered off by default.
Remember to install VMware Tools on the newly created VM for optimized performance and driver compatibility.
Q7. Explain the concept of a datastore in VMware. (Storage Management)
A datastore in VMware is a logical storage unit that can aggregate physical storage resources from one or more storage devices and provides a unified model for storing virtual machine files, templates, and ISO images. Datastores in VMware are used for:
- Storing virtual machine files (.vmx for configuration, .vmdk for disks, .nvram for BIOS settings, etc.)
- Storing templates for rapid deployment
- Holding ISO images for OS installation
Datastores can be backed by different types of physical storage like:
- Local storage on the ESXi host

- Flexibility: DRS allows for manual overrides, where an administrator can intervene for specific resource allocation decisions if needed.
Q13. Can you explain the difference between thick provision and thin provision of virtual disks? (Storage Provisioning)
Thick provision and thin provision are two methods of allocating storage to virtual disks in VMware environments:
-
Thick Provision: This method allocates the entire specified size of the virtual disk upfront. There are two types of thick provisioning:
- Thick Provision Lazy Zeroed: Creates a virtual disk in a default thick format. Space required for the virtual disk is allocated during creation, but the data that makes up the disk is not zeroed until it is written to for the first time by the VM.
- Thick Provision Eager Zeroed: Space required for the virtual disk is allocated at creation time and is zeroed immediately. This can enhance performance as data does not need to be zeroed on demand as the space is used.
-
Thin Provision: This method allocates disk space on-demand as data is written to the virtual disk. Initially, a small amount of space is allocated, which grows as needed, up to the maximum defined disk size.
The primary difference is in how disk space is allocated and when it is reserved. Thick provision ensures that the space is guaranteed but may lead to unused allocated space. Thin provision is more efficient in space utilization but requires monitoring to prevent the VM from running out of space as it grows.
Q14. What are the essential components required for a VMware virtual infrastructure? (Infrastructure Components)
The essential components required for a VMware virtual infrastructure include:

Q20. Can you explain how resource pools work in VMware? (Resource Management)
Resource pools are used in VMware to hierarchically partition available CPU and memory resources among multiple virtual machines (VMs). Here’s how resource pools work:
- Hierarchical Organization: Resource pools allow you to organize and manage resources in a hierarchical manner. You can create a tree-like structure with parent and child resource pools.
- Resource Allocation: You allocate CPU and memory resources to each resource pool, which can then be further divided among the child pools or assigned to VMs.
- Shares, Reservations, and Limits:
- Shares: Determine the relative priority of a resource pool or VM within a parent pool.
- Reservations: Guarantee a minimum amount of CPU or memory to a resource pool or VM.
- Limits: Set a maximum amount of CPU or memory usage for a resource pool or VM.
Here is an example table demonstrating how you might allocate resources within a simple hierarchy:
Resource Pool | Shares | Reservation (GHz/GB) | Limit (GHz/GB) | VMs/Child Pools |
---|---|---|---|---|
Production | High | 8 GHz / 32 GB | None | VM1, VM2 |
Development | Normal | 4 GHz / 16 GB | 6 GHz / 24 GB | VM3, VM4 |
Testing | Low | 2 GHz / 8 GB | 4 GHz / 16 GB | VM5, VM6 |
- Balancing Performance: If a VM requires more resources and they are not being utilized by others, the resource pool can allow that VM to consume more up to the limit set for the pool.
Using resource pools, administrators have greater control over resource distribution and can ensure that critical workloads have the necessary resources while maintaining overall efficiency in the environment.
Q21. Describe a scenario where you had to troubleshoot a VMware environment. What steps did you take? (Problem-Solving & Troubleshooting)
