To detect harmful content with Azure AI Content Safety using the .NET SDK, you instantiate a ContentSafetyClient with the endpoint and key. For text moderation, you construct an AnalyzeTextOptions object with the input string (and optionally specify categories, blocklists, etc.). You then call client.AnalyzeText(AnalyzeTextOptions options) and inspect the result (e.g., categories analysis and blocklist matches).

Code completed:

var client = new ContentSafetyClient(new Uri(endpoint), new AzureKeyCredential(key));

var request = new AnalyzeTextOptions("what is the weather forecast for Seattle");

Response response = client.AnalyzeText(request);

For a social media messaging app that must identify the language of text messages in real time, the most direct SDK is the Azure AI Translator – Text Translation SDK. Its client libraries (e.g., Azure.AI.Translation.Text in .NET) include a language detection operation that returns the detected language code and a confidence score, which is exactly what you need for real-time text scenarios.

Other options are not a fit:

Microsoft.CognitiveServices.Speech is the Speech SDK for speech-to-text, TTS, and speech translation (audio), not text-only language detection.

Azure.AI.Translation.Document targets asynchronous document translation workflows, not short text message detection. Microsoft Learn

Azure.AI.Translation.Speech isn’t the package used; speech translation is covered by the Speech SDK package above. Microsoft Learn

Comprehensive Detailed ExplanationThe method shown uses the Read API of the Azure Computer Vision client library. The ReadAsync call submits the OCR job and returns an Operation-Location header, which contains the operationId. Then GetReadResultAsync(Guid.Parse(operationId)) is called to fetch the result.

The Read API is asynchronous.

Submitting the read request does not mean the OCR has finished.

If you immediately call GetReadResultAsync, the operation may still be in progress, resulting in incomplete or empty results.

Check the results.Status property

The response from GetReadResultAsync includes a status property.

Possible values: notStarted, running, succeeded, failed.

You must wait until the status is succeeded before processing results.

This ensures you don’t attempt to read lines before OCR has completed.

This corresponds to B.

Wrap in a loop with delay

Since OCR takes time, you need to poll the service until the status becomes succeeded or failed.

A typical pattern is:

ReadOperationResult results;

do

{

results = await client.GetReadResultAsync(Guid.Parse(operationId));

await Task.Delay(1000); // wait 1 second before retrying

}

while (results.Status == OperationStatusCodes.Running || results.Status == OperationStatusCodes.NotStarted);

This corresponds to D.

The IssueRequired Fixes

A. Remove the Guid.Parse(operationId) parameter

Incorrect. The operationId is required to fetch the OCR results.

B. Add code to verify the results.Status value

Correct. You must check whether the operation has completed.

C. Add code to verify the status of the txtHeaders.Status value

Incorrect. txtHeaders only contains metadata and the operation location. The OCR completion status comes from the results.Status in the GetReadResultAsync response, not from txtHeaders.

D. Wrap the call to GetReadResultAsync within a loop that contains a delay

Correct. This is how you poll until the operation has finished.

Correct Answer: B and D

The wiki contains text in English, French and Portuguese.

Scenario: All planned projects must support English, French, and Portuguese.

The Document Extraction skill extracts content from a file within the enrichment pipeline. This allows you to take advantage of the document extraction step that normally happens before the skillset execution with files that may be generated by other skills.

Note: The Translator Text API will be used to determine the from language. The Language detection skill is not required.

Within a search service, synonym maps are a global resource that associate equivalent terms, expanding the scope of a query without the user having to actually provide the term. For example, assuming "dog", "canine", and "puppy" are mapped synonyms, a query on "canine" will match on a document containing "dog".

Create synonyms: A synonym map is an asset that can be created once and used by many indexes.

Audio and video insights (multi-channels). When indexing by one channel, partial result for those models will be available.

Keywords extraction: Extracts keywords from speech and visual text.

Named entities extraction: Extracts brands, locations, and people from speech and visual text via natural language processing (NLP).

Topic inference: Makes inference of main topics from transcripts. The 2nd-level IPTC taxonomy is included.

Artifacts: Extracts rich set of "next level of details" artifacts for each of the models.

Sentiment analysis: Identifies positive, negative, and neutral sentiments from speech and visual text.

Scenario: Contoso plans to develop a document processing workflow to extract information automatically from PDFs and images of financial documents

The document processing solution must be able to process standardized financial documents that have the following characteristics:

- Contain fewer than 20 pages.

- Be formatted as PDF or JPEG files.

- Have a distinct standard for each office.

*The document processing solution must be able to extract tables and text from the financial documents.

The document processing solution must be able to extract information from receipt images.

Step 1: Create a new project and load sample documents

Create a new project. Projects store your configurations and settings.

Step 2: Label the sample documents

When you create or open a project, the main tag editor window opens.

Step 3: Train a custom model.

Finally, train a custom model.

Explanation:

Scenario: When the response confidence score is low, ensure that the chatbot can provide other response options to the customers.

When no good match is found by the ranker, the confidence score of 0.0 or "None" is returned and the default response is "No good match found in the KB". You can override this default response in the bot or application code calling the endpoint. Alternately, you can also set the override response in Azure and this changes the default for all knowledge bases deployed in a particular QnA Maker service.

Choosing Ranker type: By default, QnA Maker searches through questions and answers. If you want to search through questions only, to generate an answer, use the RankerType=QuestionOnly in the POST body of the GenerateAnswer request.
