AI-102 Practice Question: Implement natural language processing solutions
Exhibit
Refer to the exhibit. $az = Get-AzResource -ResourceGroupName 'myRG' -ResourceType 'Microsoft.CognitiveServices/accounts' -Name 'myLangService' $az.Properties.apiProperties.textAnalytics.documentEndpoint = 'https://eastus.api.cognitive.microsoft.com/text/analytics/v3.1/entities/health/general' Set-AzResource -ResourceId $az.ResourceId -Properties $az.Properties -Force
A PowerShell script (exhibit) attempts to update the endpoint for an Azure AI Language resource. What is the outcome of running this script?
⚠ Common exam trap
It's easy for candidates to assume the 'endpoint' property is a simple string that can be updated like any other resource property, overlooking that it is a read-only system-generated attribute in Azure Cognitive Services.

Correct answer & explanation
✓
The script fails because the property does not exist
The PowerShell script attempts to set the 'endpoint' property on an existing Azure AI Language resource using the `Set-AzCognitiveServicesAccount` cmdlet. However, the 'endpoint' property is read-only and cannot be modified after resource creation; it is generated automatically by Azure based on the resource's name and region. Attempting to update it results in a failure because the property does not exist as a writable attribute in the resource's schema.
