1)What is service console?
A) The service console is developed based up on Redhat Linux Operating system,it is used to manage the vmkernel.
2)What are the basic commands to troubleshoot connectivity between vsphere client/vcenter to esx server?
(A)--->service mgmt-vmware restart
(restarts host agent(vmware-hostd)on vmware esx server))
---->service vmware-vpxa restart(restarts vcenter agent service)
----->service network restart(restarts management networks on esx)
(3)what is vcenter agent?
(A)vc agent is an agent installed on esx server which enables communication between vc and esx server.This agent will be installed on esx/esxi will be done when you try to add the esx host in vcenter.
(4)what is the command used to restart SSH,NTP&vmware web access?
(A)
(1)service sshd restart
(2)service ntpd restart
(3)service vmware-webaccess restart
(5)what are the types of port groups in esx?
(A)There are 3 types of port groups in esx
(1)service console port group
(2)vmkernel port group
(3)virtual machine port group
There are only 2 types of port group in esxi
(1)vmkernel port group
(2)virtual machine port group
(6)what is vmkernel?
(A) vmkernel is a proprietary kernel of vmware and is not based on any of the flavors of linux operating systems.vmkernel requires an os to boot and manage the kernel.A service console is being provided when vmware kernel is booted.only service console is based up on redhat linux os not vmkernel.
(7)what is the use of service console port?
(A)service console port group required to manage the esx server and it acts
as the management network for the esx.vcenter/vsphere clent uses the service console ip's to communicate with the esx server.
(8)what is the use of vmkernel port?
(A)vmkernel port is used by esx/esxi for vmotion,iscsi&nfs communications.esxi uses vmkernel as the management network.since it dont have service console built in it.
(9)what is the use of virtual machine port group?
(A)virtual machine port group is used by virtual machine communication.
(10)How virtual machine communicates to another servers in network?
(A)All the virtual machines which are configured i vm port group are able to connect to the other machines on the network.So this port group enables communication between Vswitch and physical switch by the use of uplink associated with the port group.
(11)What is the default number of ports configured with the virtual switch?
(A) When the time of virtual switch created,vswitch is creted with 56 ports by default.We can extend the no of ports by editing the vswitch properties.
(12)What are the different types of partitions in esx server?
(A) /-root
Swap
/var
/var/core
/opt
/home
/tmp
