PowerShell 5.0 and Desired State Configuration Quiz Questions and Answers
Answer :
Active Directory
Explanation :
The trust relationship is obtained when the
machines are members of the same Active Directory domain. Theprerequisite to use
DSC is the WinRM HTTP 5895 protocol (Windows Remote Management – that is theimplementation
of the standard WS-Management on the Windows platform). It is, therefore, necessary
to assurethe correct functioning of this component, so as to allow the remote execution
of the PowerShell code.
Each target node has to be told to use pull mode and given the URL where it can contact
the pull server to getconfigurations. To do this, you have to configure the Local
Configuration Manager (LCM) with the necessaryinformation. To configure the LCM,
you create a special type of configuration, decorated with theDSCLocalConfigurationManager
attribute.
The node keyword takes an array of strings that represent the names of the target
nodes. We provide the array ofnames by using a PowerShell filter called Where() that
accepts a script block. Inside this script block, we examineeach item in the array
and inspect whether it matches the filter.
DSC is idempotent, autonomous, and uses declarative syntax in the files.
Let’s look at some terms thatwe will use, as it’s better to have at least a basic
concept of them at the beginning. We realize we’ve covered someof these already,
but it won’t hurt to do a brief review.
An imperative language requires the user to determine what the end result should be,
and tells the computer stepby-
step how to achieve that result. It is the same as
calling an Uber, but telling the driver step-by-step how you want
to get to your destination.
The configuration scripts in DSC are based on building blocks, which we call DSC resources.
DSC resources arePowerShell modules with a specific set of options. The DSC resources
have Microsoft support, and you canrequest bug fixes and feature changes.
