Amazon Web Services AIF-C01 Exam Dumps - Actual Questions Answers

Amazon Transcribe is the correct solution for converting audio from customer calls into text, allowing the company to analyze and extract key information from the conversations.

Amazon Transcribe:

It is a fully managed automatic speech recognition (ASR) service that converts speech into text, making it easier to perform text-based analysis on audio data.

After transcribing the audio, further analysis can be performed using other AWS services like Amazon Comprehend to extract insights such as sentiment, key phrases, or entities.

Why Option B is Correct:

Conversion to Text:Transcribing audio recordings is the first step in gaining insights from spoken conversations, allowing for further processing.

Enables Further Analysis:Once the audio is transcribed into text, other tools and services can be used to analyze the content more deeply.

Why Other Options are Incorrect:

A. Amazon Lex:Is used for building conversational interfaces, not for transcribing or analyzing audio from customer calls.

C. Amazon SageMaker Model Monitor:Monitors ML models for bias and data drift, not for audio analysis.

D. Amazon Comprehend:Can analyze text but cannot transcribe audio; it would be used after transcription is completed.

To determine customer sentiments based on written customer reviews, the company can use Amazon Comprehend and Amazon Bedrock.

Amazon Comprehend:

A natural language processing (NLP) service that uses machine learning to uncover insights and relationships in text.

Can analyze customer reviews to detect sentiments (positive, negative, neutral, or mixed) automatically.

Amazon Bedrock:

Provides access to foundational models (FMs) from multiple AI companies for tasks such as text generation, summarization, and sentiment analysis.

The company can use a pre-trained sentiment analysis model available on Amazon Bedrock for processing customer reviews.

Why Other Options are Incorrect:

A. Amazon Lex:Used for building conversational interfaces like chatbots, not for sentiment analysis.

C. Amazon Polly:Converts text to speech; it doesn't analyze sentiment.

E. Amazon Rekognition:Analyzes images and videos, not text.

The average response time is the correct metric for measuring the runtime efficiency of operating AI models.

Average Response Time:

Refers to the time taken by the model to generate an output after receiving an input. It is a key metric for evaluating the performance and efficiency of AI models in production.

A lower average response time indicates a more efficient model that can handle queries quickly.

Why Option C is Correct:

Measures Runtime Efficiency:Directly indicates how fast the model processes inputs and delivers outputs, which is critical for real-time applications.

Performance Indicator:Helps identify potential bottlenecks and optimize model performance.

Why Other Options are Incorrect:

A. Customer satisfaction score (CSAT):Measures customer satisfaction, not model runtime efficiency.

B. Training time for each epoch:Measures training efficiency, not runtime efficiency during model operation.

D. Number of training instances:Refers to data used during training, not operational efficiency.
