1. What is virtualization? - 🧠ANSWER ✔✔Virtualization is the creation of a
virtual (rather than actual) version of something, such as an operating
system, a server, a storage device or network resources.
2. What is a Hypervisor? - 🧠ANSWER ✔✔It is a program that allows
multiple operating systems to share a single hardware host. Each operating
system appears to have the host's processor, memory, and other
resources all to itself. However, the hypervisor is actually controlling the
host processor and resources, allocating what is needed to each operating
system in turn and making sure that the guest operating systems (called
virtual machines) cannot disrupt each other
3. What is the difference between Esx and Esxi? - 🧠ANSWER ✔✔ESX
(Elastic Sky X) is the VMware's flagship enterprise server virtualization
platform. In ESX, VMkernel is the virtualization kernel which is managed by
a console operating system which is also called as Service console. Which

,is linux based and its main purpose is it to provide a Management interface
for the host and lot of management agents and other thrid party software
agents are installed on the service console to provide the functionalists like
hardware management and monitoring of ESX hypervisor.
ESXi (Elastic sky X Integrated) is also the VMware's flagship enterprise
server virtualization platform. In ESXi, Service console is removed. All the
VMware related agents and third party agents such as management and
monitoring agents can also run directly on the VMkernel. ESXi is ultra-thin
architecture which is highly reliable and its small code-base allows it to be
more secure with less codes to patch. ESXi uses Direct Console User
Interface (DCUI) instead of a service console to perform management of
ESXi server. ESXi installation will happen very quickly as compared to ESX
installation. ESX 4.1 is the last version availability of ESX server. After
vSphere 5, only ESXi is available.
4. Difference between ESX and GSX? - 🧠ANSWER ✔✔With VMware
Workstation and GSX Server, the software sits on top of a host operating
system such as Windows or Linux. With ESX Server, the software runs

,directly on the system's hardware, eliminating the need to install a base
OS. In fact, ESX has its own OS
5. What is VMware vMotion and what are its requirements? - 🧠ANSWER
✔✔VMware VMotion enables the live migration of running virtual machines
from one physical server to another with zero downtime, continuous service
availability, and complete transaction integrity. Without share storage you
can do VM migration with vMotion and Storage VMotion from one physical
host to another but the virtual machine have to be powered off. Note : Local
storage vMotion needs VM's powered off and share storage vMotion is live
migration where VM's can be powered on.
Below are the pre-requisites for configuring vMotion
Lisence required vsphere essential plus, standard, enterprise or enterprise
plus
Storage requirements: shared storage iSCSI SAN, FC SAN and NAS

, VMkernel Management Network should have vMotion Enable
Vswitch have the same name
CPU Compatibility
Support 1GoE 16 NIC Cards or 10 GoE 4 NICs
6. What is VMware HA? - 🧠ANSWER ✔✔VMware HA i.e. High Availability
which works on the host level and is configured on the Cluster. A Cluster
configured with HA will migrate and restart all the vms running under any of
the host in case of any host-level failure automatically to another host
under the same cluster. VMware HA continuously monitors all ESX Server
hosts in a cluster and detects failures.
VMware HA agent placed on each host maintains a heartbeat with the
other hosts in the cluster using the service console network. Each server
sends heartbeats to the others servers in the cluster at five-second
intervals. If any servers lose heartbeat over three consecutive heartbeat
