Q1. What is the main difference between generative AI and traditional discriminative/predictive AI models?

A. Generative AI creates new content (text, images, audio) resembling its training data, while discriminative models classify or predict labels for given inputs
B. Generative AI can only process numerical data, while discriminative AI only processes text
C. Discriminative AI always requires more training data than generative AI
D. Generative AI does not require any training data at all

Show answer & explanation

✓ Answer: A. Generative AI creates new content (text, images, audio) resembling its training data, while discriminative models classify or predict labels for given inputs

Generative models learn the underlying distribution of training data well enough to produce new, plausible examples, such as generating an image or paragraph. Discriminative models instead learn a boundary or mapping to predict a label or value for a given input, such as classifying an image as 'cat' or 'dog'.

Q2. What is the primary architectural innovation that underlies most modern large language models?

A. Convolutional layers with max pooling
B. The transformer architecture with self-attention mechanisms
C. Decision tree ensembles
D. K-means clustering layers

Show answer & explanation

✓ Answer: B. The transformer architecture with self-attention mechanisms

The transformer architecture, introduced in 2017, uses self-attention to weigh the relevance of different tokens in a sequence to one another, enabling it to model long-range context far better than earlier recurrent approaches. Convolutional and clustering methods are used in other machine learning domains, not as the core of modern LLMs.

Q3. A company observes that their foundation model gives significantly different quality answers depending on whether instructions appear at the start or end of a long prompt. What prompt engineering practice addresses this?

A. Placing the most important instructions clearly and, where relevant, repeating them or positioning them prominently (e.g., near the start or end) rather than burying them in the middle
B. Always using the maximum possible context window regardless of relevance
C. Disabling the system prompt entirely
D. Switching exclusively to zero-shot prompting for all tasks

Show answer & explanation

✓ Answer: A. Placing the most important instructions clearly and, where relevant, repeating them or positioning them prominently (e.g., near the start or end) rather than burying them in the middle

Models can be less attentive to instructions buried in the middle of very long prompts (a known 'lost in the middle' effect), so best practice is to place critical instructions prominently — often near the beginning and/or restated near the end — rather than relying on the model to fully weigh every position equally.
