Microsoft AI-102 Exam Dumps

In the Microsoft Bot Framework SDK, bots communicate using activities (messages, events, conversation updates, etc.).

To respond to events (like conversation started, member added, or custom event activities), you use an ActivityHandler.

The ActivityHandler class provides methods you can override, such as OnMessageActivityAsync, OnMembersAddedAsync, or custom event handlers, to send custom text responses.

Other options:

Adaptive card (A) used for rich UI responses, not for handling events.

Dialog (C) used for managing conversation flow, not event handling.

Skill (D) used to integrate another bot's functionality, not for handling custom events.

Correct Answe r: B

You need to identify files containing specific phrases using cosine similarity. Cosine similarity is used in vector embeddings, not in generative LLM completion.

text-embedding-ada-002 Correct model for embeddings and cosine similarity search.

GPT-4, GPT-3.5 Turbo, GPT-4-32k Generative models, not designed for embedding similarity.

Correct Answe r: A. text-embedding-ada-002

The requirement is:

Bot asks for a date input.

Bot repeats the question until a valid date is provided.

Bot allows cancellation of transaction.

This is exactly what Prompts in Bot Framework are designed for.

Example: DateTimePrompt asks for a date, validates the input, and automatically re-prompts if invalid.

Waterfall is for multi-step dialog flows, but the specific requirement is repeating until valid input --- handled by Prompts.

Adaptive and Action dialogs are not relevant here in SDK context.

Correct Answe r: A

Comprehensive Detailed Explanation

If a chatbot must query a knowledge base (KB), the Bot Framework uses QnAMakerDialog (inherited into Azure Cognitive Service for Language's Question Answering).

AdaptiveDialog manages complex dialog flows but not specifically KB querying.

ComponentDialog organizes dialogs, but again, not specific for knowledge bases.

SkillDialog is used when invoking another bot (skill), not for KB queries.

Correct Answe r: B. QnAMakerDialog

The exhibit shows incremental increases by quarter leading to a cumulative running total, which is best represented with a waterfall chart.

Ribbon chart shows ranking changes over time, not cumulative totals.

Bar chart shows simple comparisons, not running totals.

Decomposition tree is for drill-down analysis, not running totals.
