master image doesn't get accidentally changed or modii ed. Then, once a template has been
created, vCenter Server can clone VMs from that template, customizing them in the process
to ensure that each one is unique.
Master It Of the following tasks, which are appropriate to be performed on a VM run-
ning Windows Server 2008 that will eventually be turned into a template?
a.
Align the guest OS's i le system to a 64 KB boundary.
b.
Join the VM to Active Directory.
c.
Perform some application-specii c coni gurations and tweaks.
d. Install all patches from the operating system vendor.
Solution The answers are as follows:
a.
Yes. This is an appropriate task but unnecessary because Windows Server 2008
installs already aligned to a 64 KB boundary. Ensuring alignment ensures that all
VMs then cloned from this template will also have their i lesystems properly
aligned.
b.
No. This should be done by the vSphere Web Client Guest Customization Wizard
or a customization specii cation.
c.
No. Templates shouldn't have any application-specii c i les, tweaks, or coni gura-
tions unless you are planning on creating multiple application-specii c templates.
d. Yes. This helps reduce the amount of patching and updating required on any VMs
cloned from this template.
Deploy new VMs from a template. By combining templates and cloning, VMware vSphere
administrators have a powerful way to standardize the coni guration of VMs being deployed,
protect the master images from accidental change, and reduce the amount of time it takes to
provision new guest OS instances.
Master It Another VMware vSphere administrator in your environment starts the wiz-
ard for deploying a new VM from a template. He has a customization specii cation he'd
like to use, but there is one setting in the specii cation he wants to change. Does he have
to create an all-new customization specii cation?
Solution No. He can select the customization specii cation he wants to use and then
select Use The Customization Wizard To Customize This Specii cation to supply the al-
ternate values he wants to use for this particular VM deployment. He also has the option
of cloning the existing customization specii cation and then changing the one setting
within this new clone.
Deploy a VM from an OVF template. Open Virtualization Format (OVF, formerly Open
Virtual Machine Format) templates provide a mechanism for moving templates or VMs
between different instances of vCenter Server or even entirely different and separate instal-
lations of VMware vSphere. OVF templates combine the structural dei nition of a VM along
with the data in the VM's virtual hard disk and can exist either as a folder of i les or as a
single i le. Because OVF templates include the VM's virtual hard disk, OVF templates can
