Question 1

Which architectural component introduced in the 2017 Vaswani et al paper is the foundation of modern large language models such as Alibaba's Qwen series?

Recurrent neural network (RNN) Transformer with self-attention Long short-term memory (LSTM) Convolutional neural network (CNN)

Correct Answer:

Transformer with self-attention

Question 2

In a Transformer self-attention block, what role do the Query, Key and Value projections play?

Query and Key compute attention weights, which are then used to combine Values into the output Query produces the output, Key and Value are discarded after training Query stores the vocabulary, Key stores positions, Value stores embeddings All three are identical copies of the input embedding

Correct Answer:

Query and Key compute attention weights, which are then used to combine Values into the output

Question 3

Which Transformer variant is best suited for autoregressive text generation as used by Qwen-Chat?

Encoder-only (BERT-style) Decoder-only with causal masking Encoder-decoder (T5-style) Bidirectional encoder with pooling

Correct Answer:

Decoder-only with causal masking

Question 4

What does Byte Pair Encoding (BPE) do during LLM tokenization?

Encrypts user prompts before sending them to the model Iteratively merges the most frequent adjacent character or subword pairs to build a fixed vocabulary Splits text strictly on whitespace and punctuation Converts each Unicode character into its ASCII equivalent

Correct Answer:

Iteratively merges the most frequent adjacent character or subword pairs to build a fixed vocabulary

Question 5

An embedding model maps a sentence to a 1024-dimensional dense vector. Which downstream task is the most natural use for this vector?

Storing in a vector database for semantic similarity search Decoding back into the original sentence character by character Replacing the model's tokenizer at inference time Serving as a system prompt

Correct Answer:

Storing in a vector database for semantic similarity search
