Graded Quiz: Generative AI Architecture :Generative AI and LLMs: Architecture and Data Preparation (IBM AI Engineering Professional Certificate) Answers 2025

1. Best use of GANs for Rosy’s fashion app

❌ Utilizing natural language for chatbot conversations
❌ Translating text between languages
Generating realistic images based on training data
❌ Generating text from voice conversations

Explanation:
GANs are powerful for image generation — perfect for fashion design, virtual try-ons, or creating new clothing styles.


2. Best architecture for a memory-efficient chatbot on limited hardware

Recurrent neural networks (RNNs)
❌ BERT
❌ Variational autoencoders (VAEs)
❌ GANs

Explanation:
RNNs are lightweight and generate responses based on immediate previous context, making them ideal for resource-constrained devices.


3. Which model primarily functions as a decoder?

❌ BERT
❌ BART
Generative Pretrained Transformer (GPT)
❌ T5

Explanation:
GPT is a decoder-only model specialized in text generation.


4. Which GenAI capability simplifies complex patient test results?

❌ Predict patient results
Generate contextually relevant text from existing data
❌ Compress data
❌ Create 3D images

Explanation:
GenAI models can rewrite and simplify medical information into understandable language.


5. Why are GPT models called “large”?

❌ They have high memory requirements
❌ They are used in many industries
They contain billions of parameters
❌ They are applied to many tasks

Explanation:
GPTs are called “large” because of their massive parameter count, which enables sophisticated language understanding and generation.
