VCP-DCV 6 Questions with Correct Answers
2.3 ESXi features memory hardening, random unpredictable memory addresses; module
integrity, digital signing; small disk footprint. 64bit only.
2.3 VMkernel aka. ESXi hypervisor
2.3 VMM virtual machine monitor request resources from VMkernel. One per VM.
presents virtual hardware to the virtual machine.
2.3 ESXi accessed thru interfaces (5) web client (thru vcenter); vsphere client; vsphere
command line; vmware api and sdk; CIM (common info model)
2.3 CIM management standard promoted by distributed management task force. Health
status of ESXi HW only found thru CIM
2.3 DCUI Direct Console User Interface. similar to bios. keyboard UI. used for initial and
basic installation. including hostname, IP config, DNS servers. config network adapter used by
,management network test/reboot/disable functionality. enable ESXi shell for troubleshooting and
SSH.
2.3 DCUI lockdown mode disables all access except direct root access to ESXi hosts.
forces all ops to vCenter Server system.
2.3 DNS and Routing tab lets change hostname/domain, DNS users, search domain,
VMkernel default gateway. Click properties in upper right.
2.3 vCenter vCenter allows ability to centrally mange multiple ESXi hosts and their vms.
back-end system manages features like HA and vmotion. vsphere client connects to it.
3.1 VM files - .vmx Configuration file
3.1 VM files - .vmdk disk configuration characteristics. virtual disk files (2) - vm.vmdk
and vm_name-flat.vmdk. one file each for each virtual disk.
3.1 VM files - .nvram file with Vm's BIOS settings
,3.1 VM files - .log Vm's log file
3.1 VM files - .vswp swap files used to reclaim memory during period of contention. page
file in windows, swap in linux
3.1 VM files - .vmsd contains vm snapshots. snapshot description file. empty if no
snapshots in vm
3.1 .vmss file created when VM suspended, VM suspend file
3.1 VM files - .vmtx if vm is a template .vmx becomes .vmtx
3.1 VMCI vm communication interface provides networking between vms on same host
and to the host itself(hypervisor). faster then VMXNET3, can go 10 Gbit/s
3.1 VM hardware limitations up to 2 IDE controller devices, 3 parallel ports, 32
serial/com ports, 1 usb controler, 1 floppy, 4 scsi adapters, 15 devices (drives) per adapter,
keyboard, mouse, 128 vCPUS, 4 TB ram, hardware 3D, 10 NICS.
, 3.1 VM hardware version each VMware product has corresponding vm hardware version.
each level supports 5 major releases. vmware esxi 6 compatiable with 11, 5.5 10, etc..
3.1 Virtual Hardware version 11 More h/w attached basically. VMXNET3 driver support
(windows), guest authentcation, HGFS, vCPU capacity increased to 128 cpus, increased RAM
(4TB)..
3.1 SCSI adapter chosen by default based on guest OS.
3.1 VMware Vsphere VMFS datastore container that holds multiple virtual disks
3.1 Thick provisioning Uses all defined disk space at creation of virtual disks regardless
of actual data in guest OS.
3.1 Thick - thick provision eager Zeroed every block is prefilled w/ a zero. can use fault
tolerance with this method.
3.1 Thick - thick provision lazy Zeroed every block fileld with zero when data written to
the block for the first time. (default type disk)
