Amazon AWS Certified AI Practitioner Sample Questions (Q388-Q393):

NEW QUESTION # 388
An online learning company with large volumes of education materials wants to use enterprise search.

Answer: B


NEW QUESTION # 389
A financial company has offices in different countries worldwide. The company requires that all API calls between generative AI applications and foundation models (FM) must not travel across the public internet.
Which AWS service should the company use?

Answer: D

Explanation:
AWS PrivateLink provides private connectivity between VPCs, AWS services, and on-premises networks, ensuring traffic does not traverse the public internet.
A is correct:
"AWS PrivateLink provides private connectivity to services across VPCs, keeping API traffic off the public internet." (Reference: AWS PrivateLink Overview) B (Amazon Q) is a generative AI assistant, not a network security/control tool.
C (CloudFront) is a CDN, not for private API calls.
D (CloudTrail) is for logging and monitoring, not secure connectivity.


NEW QUESTION # 390
A company is using a large collection of web data to produce a large language model (LLM). The company completes a random initialization of the model's weights. Next, the company fits the model to the data through a language-modeling objective function.
Which stage of the model training process does this scenario describe?

Answer: A

Explanation:
The verified answer is B. Pre-training . The scenario describes the first major training stage for a large language model, where the model starts with randomly initialized weights and learns broad language patterns from a very large corpus of unlabeled or self-supervised text data. AWS describes large language models as very large deep learning models that are pre-trained on vast amounts of data . In this stage, the model is not yet being customized for a narrow business task; instead, it learns general-purpose linguistic and semantic representations from large-scale text.
AWS machine learning guidance explains that pre-training teaches the model broad linguistic and semantic patterns , including grammar, context, world knowledge, reasoning, and token prediction, using self- supervised learning approaches such as masked language modeling or causal language modeling. That exactly matches the question's description: random weight initialization followed by fitting the model to a large web dataset using a language-modeling objective. This is the core training process used to create a foundation model or LLM before later adaptation.
Option A. Fine-tuning is incorrect because AWS defines fine-tuning as training a pretrained model on a new dataset rather than training from scratch. Fine-tuning adapts an existing model for a specific task or domain and usually requires less data and less training time than pre-training.
Option C. Model selection is incorrect because model selection refers to choosing an appropriate model or architecture, not training the model weights from random initialization. Option D. Deployment is also incorrect because AWS describes deployment as the stage where a trained model is made available for inference or predictions, such as through SageMaker inference endpoints.
Therefore, because the company is training an LLM from initial weights on a large web corpus using a language-modeling objective, the stage is pre-training .


NEW QUESTION # 391
What is tokenization used for in natural language processing (NLP)?

Answer: C

Explanation:
The verified answer is C. To break text into smaller units for processing. AWS defines tokenization as the process of breaking input text into smaller units called tokens. These tokens can be words, subwords, or characters, and tokenization is used as a preprocessing step for natural language processing tasks. This exactly matches option C.
Tokenization is fundamental because machine learning and generative AI systems do not process raw human language in the same way humans read sentences. Text must first be split into units the model can represent, count, embed, and process mathematically. For example, a sentence might be split into words, subword pieces, punctuation, or characters depending on the tokenizer and model architecture. These tokens can then be converted into numerical representations for downstream tasks such as classification, summarization, question answering, translation, or text generation.
Option A is incorrect because encryption protects data confidentiality by transforming readable text into unreadable ciphertext. Tokenization in NLP is not encryption. The original purpose is linguistic and computational processing, not data protection.
Option B is incorrect because compression reduces file size. Tokenization may reduce text into units, but its purpose is not storage compression. It prepares text for analysis by NLP systems.
Option D is incorrect because translation is a downstream NLP task that converts text from one language to another. Tokenization may be used before translation, but it is not itself translation.
The wording "break text into smaller units" is the defining phrase. Therefore, the correct answer is C.


NEW QUESTION # 392
A social media company wants to use a large language model (LLM) for content moderation. The company wants to evaluate the LLM outputs for bias and potential discrimination against specific groups or individuals.
Which data source should the company use to evaluate the LLM outputs with the LEAST administrative effort?

Answer: D
