Chapter 7 Flashcards
To deploy a virtual machine, you must provide such information as the virtual machine name, inventory _______, host, ______, and guest operating system customization data.
location, datastore
Cloning a virtual machine creates a _________ of the virtual machine with ________ configuration and installed software as the original.
duplicate, same
When you clone a virtual machine or deploy it from a template, to customize its guest operating system you change which 3 properties?
- Computer name
- Network settings
- License settings
Customizing guest operating systems can help prevent __________ that occur when virtual machines with identical settings are deployed
conflicts
_____ and _______ can also be added while the virtual machine is powered on.
CPU, memory
This feature is called the CPU hot-plug and memory hot-add option.
An _______ enables a virtual machine to gain direct access to a physical LUN.
RDM (a -rdm.vmdk file)
Encapsulating disk information in the RDM enables the VMkernel to lock the LUN so that only _____ virtual machine can write to it.
one
What items need to be defined when creating a RDM? (4)
Target LUN: LUN that the RDM will map to
Mapped datastore: Stores the RDM file with the virtual machine or on a different datastore
Compatibility mode
Virtual device node
After you increase the size of a virtual disk, you must increase the size of the ____ system on this disk.
file
Use the appropriate tool in the guest operating system to enable the file system to use the newly allocated disk space.
Inflating a thin-provisioned disk converts a thin disk to a virtual disk in _______-__________ format.
thick-provision
The _____ ______ panel enables you to set a delay between the time when a virtual machine is turned on and the guest operating system starts to boot.
Boot Delay
*A delayed boot can help stagger virtual machine startups when several virtual machines are being powered on.
What are the 4 different types of virtual machine migrations?
Cold: Migrate a virtual machine that is powered off. Suspended: Migrate a virtual machine that is suspended.
vSphere vMotion: Migrate a virtual machine that is powered on.
vSphere Storage vMotion: Migrate a virtual machine’s files, while the virtual machine is powered on, to another datastore.
The source and destination host must meet these certain requirements for a vSphere vMotion migration to be successful: (4)
- SAN visibility of virtual disks
- Gigabit Ethernet (or greater) interconnection
- Consistent network configuration, both physical and virtual
- Source and destination server CPUs from the same compatibility group
A virtual machine snapshot contains the following: (3)
- Setting state - vm settings (.nvram, .vmx) + pwoer state
- Disk state - state of vm assosciate disks
memory State - contents of vm memory
Snapshots are useful when you want to revert repeatedly to the same _______ without creating new machines
state
The snapshot state file has a _____ extension and is used to store the state of a virtual machine when a snapshot is taken
.vmsn
When you _______ a snapshot it returns all the items to the state it was in when the snapshot was taken
revert
A vApp is an object in the vCenter Server inventory: it is used to ?
be a container for one or more virtual machines.
package and manage multitiered applications.
An ____ file is a collection of virtual machine files
OVF
A _____ is a single file that needs to be unzipped and is a portable vm format
OVA
After creating the vApp, you should modify these certain vApp settings?
• Resource allocation:
Determines how CPU and memory should be allocated for the vApp.
• IP allocation policy:
Determines how IP addresses are allocated for the vApp
• Advanced settings: Product and vendor information, custom properties, and IP allocation
A _______ ________ is a repository of OVF templates and other files that can be shared and synchronized across vCenter Server systems.
content library
_______ and _______ is a key reason to install and use a content library. Sharing the content and ensuring that the content is kept up to date is a major task.
Storage , consistency
What are the three types of content libraries?
local, published, and subscribed
