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
What is a local content library?
simplest form of library:
Content can be added, modified, and deleted by the administrator.
What is a published content library?
local library that is made available for subscription.
What is a subscribed content library?
- subscribed to a published library.
- cannot make changes to the subscribed library, and it cannot be published.
How do you subscribe to a content library?
Subscription is performed through a dialog box. Selecting the Enable automatic synchronization with an external library check box:
- then enter the URL, which was generated during the publication of the content library, and subscribe to it.
True or false?
You can create a content library in the vSphere Web Client and populate it with templates to use to deploy virtual machines or vApps in your virtual environment.
True!
True of False?
You can use virtual machine snapshots to preserve the state of the virtual machine so that you can return to the same state repeatedly.
True
True or False?
You cant move virtual machines while they are powered on.
False!
You can using vMotion in vSphere
