hard📝 Application Q15 of 15

PowerShell - System Administration

AUse a loop with Install-WindowsFeature for each feature name in an array

BRun Install-WindowsFeature once with all feature names separated by commas

CRun Get-WindowsFeature and pipe output to Install-WindowsFeature

DUse Uninstall-WindowsFeature first, then Install-WindowsFeature for each feature

Step-by-Step Solution

Solution:

Step 1: Understand installing multiple features
PowerShell's Install-WindowsFeature accepts multiple feature names as a comma-separated list in the -Name parameter, but it is recommended to use a loop for clarity and error handling.
Step 2: Evaluate options
A loop with Install-WindowsFeature for each feature name in an array is the best approach for scripting multiple installs. Running once with all names separated by commas is possible but less flexible. Piping Get-WindowsFeature output would attempt to install all features, which is dangerous. Using Uninstall-WindowsFeature first is inefficient and risky.
Final Answer:
Use a loop with Install-WindowsFeature for each feature name in an array -> Option A
Quick Check:
Looping Install-WindowsFeature for each feature = best practice [OK]

Quick Trick: Use a loop to install multiple features individually for better control [OK]
