Exam AZ-400 topic 18 question 1 discussion

more on this: Specifies how the LCM actually applies the configuration to the target nodes. Possible values are "ApplyOnly","ApplyAndMonitor", and "ApplyAndAutoCorrect". ApplyOnly: DSC applies the configuration and does nothing further unless a new configuration is pushed to the target node or when a new configuration is pulled from a service. After initial application of a new configuration, DSC does not check for drift from a previously configured state. Note that DSC will attempt to apply the configuration until it is successful before ApplyOnly takes effect. ApplyAndMonitor: This is the default value. The LCM applies any new configurations. After initial application of a new configuration, if the target node drifts from the desired state, DSC reports the discrepancy in logs. Note that DSC will attempt to apply the configuration until it is successful before ApplyAndMonitor takes effect. ApplyAndAutoCorrect: DSC applies any new configurations. After initial application of a new configuration, if the target node drifts from the desired state, DSC reports the discrepancy in logs, and then re-applies the current configuration.

Change to ApplyAndAutoCorrect

Correct answer

A is the answer. https://learn.microsoft.com/en-us/powershell/dsc/managing-nodes/metaconfig?view=dsc-1.1#basic-settings ConfigurationMode - ApplyOnly: DSC applies the configuration and does nothing further unless a new configuration is pushed to the target node or when a new configuration is pulled from a service. After initial application of a new configuration, DSC does not check for drift from a previously configured state. Note that DSC will attempt to apply the configuration until it is successful before - ApplyAndAutoCorrect: DSC applies any new configurations. After initial application of a new configuration, if the target node drifts from the desired state, DSC reports the discrepancy in logs, and then re-applies the current configuration.

A. Change the value of the ConfigurationMode parameter. The current technical issue is that the test servers are experiencing configuration drift over time, and the Azure Automation State Configuration is failing to correct the configurations. The Register-AzureRmAutomationDscNode command is used to register the nodes with the Azure Automation State Configuration. One of the parameters of this command is the ConfigurationMode parameter, which specifies the mode in which the configuration should be applied. The ApplyOnly mode is currently being used, which means that the configuration will only be applied, but not checked or corrected. To resolve the current technical issue, the ConfigurationMode parameter should be changed to ApplyAndAutoCorrect, which will apply the configuration and also check and correct any drift. Therefore, option A is the correct answer.

You should add scenario to the question. "Scenario: Current Technical Issue The test servers are configured correctly when first deployed, but they experience configuration drift over time. Azure Automation State Configuration fails to correct the configurations. Azure Automation State Configuration nodes are registered by using the following command. Register-AzureRmAutomationDscNode -ResourceGroupName 'TestResourceGroup' -AutomationAccountName 'LitwareAutomationAccount' -AzureVMName $vmanme -ConfigurationMode 'ApplyOnly' To resolve the current technical issue, what should you do to the Register-AzureRmAutomationDscNode command?"

'"Azure Automation State Configuration fails to correct the configurations" https://docs.microsoft.com/en-us/powershell/module/azurerm.automation/register-azurermautomationdscnode?view=azurermps-6.13.0 "-ConfigurationMode Specifies the DSC configuration mode. Valid values are: ApplyAndMonitor ApplyAndAutocorrect ApplyOnly" Answer is A

ApplyAndAutocorrect option is all that we need there, just see get-help Register-AzAutomationDscNode

Given answer is correct Possible values are "ApplyOnly","ApplyAndMonitor", and "ApplyAndAutoCorrect". Here you can use ApplyAndAutoCorrect Sachin Kadam
