- A
Hyperparameter configuration (e.g., learning rate, batch size)
Hyperparameters define the training process and are required for fine-tuning.
- B
A separate inference endpoint for testing during training
Why wrong: Testing is done via the validation dataset; an inference endpoint is not needed during training.
- C
Training dataset in JSONL format with prompt and completion
Fine-tuning requires labeled data to guide the model.
- D
Validation dataset for model evaluation
A validation set is used to monitor overfitting and tune hyperparameters.
- E
Model architecture code for the Titan model
Why wrong: Bedrock manages the model architecture; you do not need to provide code.

AIF-C01 Generative AI and Foundation Models Practice Question
This AIF-C01 practice question tests your understanding of generative ai and foundation models. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A data scientist is preparing to fine-tune an Amazon Titan model for a domain-specific text classification task. Which THREE components are essential for the fine-tuning process on Amazon Bedrock? (Choose THREE.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Hyperparameter configuration (e.g., learning rate, batch size)
Option A is correct because hyperparameters such as learning rate, batch size, and number of epochs directly control the optimization process during fine-tuning on Amazon Bedrock. These settings determine how the model updates its weights based on the training data, and they must be configured to achieve convergence without overfitting or underfitting.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse the need for a separate inference endpoint with the ability to evaluate during training, but Bedrock allows evaluation using the validation dataset without an extra endpoint, and they may also mistakenly think they need to provide model architecture code when Bedrock abstracts that away as a managed service.
Detailed technical explanation
How to think about this question
During fine-tuning on Bedrock, the training dataset must be in JSONL format with 'prompt' and 'completion' fields, and the validation dataset is used to monitor metrics like loss and accuracy to prevent overfitting. Hyperparameters such as learning rate (e.g., 1e-5) and batch size (e.g., 8) are passed in the fine-tuning job configuration, and Bedrock automatically handles weight updates using techniques like LoRA or full fine-tuning depending on the model size.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
