Question 5 of 40

5. Question

Category: None

AI102-Q45

Your company uses an Azure Cognitive Services solution to detect faces in uploaded images. The method to detect the faces uses the following code.

static async Task DetectFaces(string imageFilePath)
{
    HttpClient client = new HttpClient();
    DefaultRequestHeaders.Add(“Ocp-Apim-Subscription-Key”, subscriptionKey) ;
    string requestParameter = “detectionModel=detection_01éreturnFaceId=true&returnFaceLandmarks=false”;
    string uri = endpoint + “/face/v1.0/detect?” + requestParameters;
    HttpResponseMessage response;
    byte[] byteData = GetImagesAsByteArray (imageFilePath) ;
    using (ByteArrayContent content = new ByteArrayContent (byteData) )
    {
        Headers.ContentType = new MediaTypeHeaderValue (“application/octet-stream”) ;
        response = awaitPostAsync(uri, content);
        string contentString = await Content.ReadAsStringAsync();
        ProcessDetection(contentString) ;
    }
}

You discover that the solution frequently fails to detect faces in blurred images and in images that contain sideways faces.

You need to increase the likelihood that the solution can detect faces in blurred images and images that contain sideways faces.

What should you do?

Use a different version of the Face API.

Use the Computer Vision service instead of the Face service.

Use the Identify method instead of the Detect method.

Change the detection model.

client.accounts.create(resource_group_name, resource_name, parameters)

You need to call the function to create a free Azure resource in the West US Azure region. The resource will be used to generate

captions of images automatically.

Question 7 of 40

7. Question

Category: None

AI102-Q47

You are developing a method that uses the Computer Vision client library. The method will perform optical character

recognition (OCR) in images. The method has the following code.

def read_file_url(computervision_client, url_file):

read_response = computervision_client.read(url_file, raw=True)

read_operation_location = read_response.headers[“Operation-Location”]

operation_id = read_operation_location_split(“/”) [-1]

read_result = computervision_client.get_read_result (operation_id)

for page in read_result.analyze_ result.read_results:

for line in page.lines:

print (line.text)

During testing, you discover that the call to the GetReadResultAsync method occurs before the read operation is complete.

You need to prevent the GetReadResultAsync method from proceeding until the read operation is complete.

Which two actions should you perform? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

Remove the operation_id parameter.

Add code to verify the read_results.status value.

Add code to verify the status of the read_operation_location value.
