Question 61

Report Export Collapse

You are training a Language Understanding model for a user support system.

You create the first intent named GetContactDetails and add 200 examples.

You need to decrease the likelihood of a false positive.

What should you do?

Enable active learning.
Enable active learning.
Add a machine learned entity.
Add a machine learned entity.
Add additional examples to the GetContactDetails intent.
Add additional examples to the GetContactDetails intent.
Add examples to the None intent.
Add examples to the None intent.
Suggested answer: A
Explanation:

Active learning is a technique of machine learning in which the machine learned model is used to identify informative new examples to label. In LUIS, active learning refers to adding utterances from the endpoint traffic whose current predictions are unclear to improve your model.

DRAG DROP

You are building a Language Understanding model for purchasing tickets.

You have the following utterance for an intent named PurchaseAndSendTickets.

Purchase [2 audit business] tickets to [Paris] [next Monday] and send tickets to [[email protected]]

You need to select the entity types. The solution must use built-in entity types to minimize training data whenever possible.

Which entity type should you use for each label? To answer, drag the appropriate entity types to the correct labels. Each entity type may be used once, more than once, or not at all.

You may need to drag the split bar between panes or scroll to view content.

Correct answer: Microsoft AI-102 image answer Question 62 83993 09262024054204000
Explanation:

Box 1: GeographyV2

The prebuilt geographyV2 entity detects places. Because this entity is already trained, you do not need to add example utterances containing GeographyV2 to the application intents.

Box 2: Email

Email prebuilt entity for a LUIS app: Email extraction includes the entire email address from an utterance. Because this entity is already trained, you do not need to add example utterances containing email to the application intents.

Box 3: Machine learned

The machine-learning entity is the preferred entity for building LUIS applications.

You need to build a chatbot that meets the following requirements:

Supports chit-chat, knowledge base, and multilingual models

Performs sentiment analysis on user messages

Selects the best language model automatically

What should you integrate into the chatbot?

Language Understanding, Text Analytics, and QnA Maker
Language Understanding, Text Analytics, and QnA Maker
Text Analytics, Translator, and Dispatch
Text Analytics, Translator, and Dispatch
Suggested answer: C
Explanation:

Language Understanding: An AI service that allows users to interact with your applications, bots, and IoT devices by using natural language.

QnA Maker is a cloud-based Natural Language Processing (NLP) service that allows you to create a natural conversational layer over your data. It is used to find the most appropriate answer for any input from your custom knowledge base (KB) of information.

Text Analytics: Mine insights in unstructured text using natural language processing (NLP)—no machine learning expertise required. Gain a deeper understanding of customer opinions with sentiment analysis. The Language Detection feature of the Azure Text Analytics REST API evaluates text input

Incorrect Answers:

A, B, D: Dispatch uses sample utterances for each of your bot’s different tasks (LUIS, QnA Maker, or custom), and builds a model that can be used to properly route your user’s request to the right task, even across multiple bots.

Question 66

Report Export Collapse

You have the following C# method for creating Azure Cognitive Services resources programmatically.

Microsoft AI-102 image Question 4 83925 09262024174203000000

You need to call the method to create a free Azure resource in the West US Azure region. The resource will be used to generate captions of images automatically.

Which code should you use?

create_resource(client, "res1", "ComputerVision", "F0", "westus")
create_resource(client, "res1", "ComputerVision", "F0", "westus")
create_resource(client, "res1", "CustomVision.Prediction", "F0", "westus")
create_resource(client, "res1", "CustomVision.Prediction", "F0", "westus")
create_resource(client, "res1", "ComputerVision", "S0", "westus")
create_resource(client, "res1", "ComputerVision", "S0", "westus")
create_resource(client, "res1", "CustomVision.Prediction", "S0", "westus")
create_resource(client, "res1", "CustomVision.Prediction", "S0", "westus")
Suggested answer: B
Explanation:

Many of the Cognitive Services have a free tier you can use to try the service. To use the free tier, use F0 as the SKU for your resource. There are two tiers of keys for the Custom Vision service. You can sign up for a F0 (free) or S0 (standard) subscription through the Azure portal.

Incorrect Answers:

A: There is no free tier (F0) for ComputerVision.
