You are planning the product creation project.
You need to recommend a process for analyzing videos.
Which four actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order. (Choose four.)
Explanation:
Scenario: All videos must have transcripts that are associated to the video and included in product descriptions.
Product descriptions, transcripts, and all text must be available in English, Spanish, and Portuguese.
Step 1: Upload the video to blob storage
Given a video or audio file, the file is first dropped into a Blob Storage. T
Step 2: Index the video by using the Video Indexer API.
When a video is indexed, Video Indexer produces the JSON content that contains details of the specified video insights. The insights include: transcripts, OCRs, faces, topics, blocks, etc.
Step 3: Extract the transcript from the Video Indexer API.
Step 4: Translate the transcript by using the Translator API.

You have an Azure subscription that contains an Azure OpenAI resource named AH.
You need to analyze an image to obtain a text descnption.
Which four actions should you perform in sequence from Azure OpenAI Studio? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Explanation:
Key Knowledge:
• To analyze images with Azure OpenAI, you must use a GPT-4 model with vision support (model version vision-preview).
• This requires deploying a GPT-4 model for vision.
• Then you use the Chat playground (not completions, not DALL-E) since you want analysis, not generation.
• You need to give the assistant instructions in the system message field (e.g., “You are an AI assistant that describes images”).
• Finally, you upload an image and prompt the model to describe it.
Correct Sequence:
HOTSPOT
You are developing a service that records lectures given in English (United Kingdom).
You have a method named Append To Transcript File that takes translated text and a language identifier.
You need to develop code that will provide transcripts of the lectures to attendees in their respective language. The supported languages are English, French, Spanish, and German.
How should you complete the code? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Explanation:
Box 1: {"fr", "de", "es"}
A common task of speech translation is to specify target translation languages, at least one is
required but multiples are supported. The following code snippet sets both French and German as translation language targets.
static async Task TranslateSpeechAsync()
{
var translationConfig =
SpeechTranslationConfig.FromSubscription(SPEECH__SUBSCRIPTION__KEY,
SPEECH__SERVICE__REGION);
translationConfig.SpeechRecognitionLanguage = "it-IT";
// Translate to languages. See, https://aka.ms/speech/sttt-languages translationConfig.AddTargetLanguage("fr"); translationConfig.AddTargetLanguage("de");
}
Box 2: TranslationRecognizer
After you’ve created a SpeechTranslationConfig, the next step is to initialize a TranslationRecognizer.
Example code:
static async Task TranslateSpeechAsync()
{
var translationConfig =
SpeechTranslationConfig.FromSubscription(SPEECH__SUBSCRIPTION__KEY,
SPEECH__SERVICE__REGION);
var fromLanguage = "en-US";
var toLanguages = new List<string> { "it", "fr", "de" }; translationConfig.SpeechRecognitionLanguage = fromLanguage; toLanguages.ForEach(translationConfig.AddTargetLanguage);
using var recognizer = new TranslationRecognizer(translationConfig);
}
You need to upload speech samples to a Speech Studio project.
How should you upload the samples?
- A . Combine the speech samples into a single audio file in the .wma format and upload the file.
- B . Upload a .zip file that contains a collection of audio files in the .wav format and a corresponding text transcript file.
- C . Upload individual audio files in the FLAC format and manually upload a corresponding transcript in Microsoft Word format.
- D . Upload individual audio files in the .wma format.
B
