AIF-C01 Fundamentals of Generative AI Practice Question
This AIF-C01 practice question tests your understanding of fundamentals of generative ai. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which THREE factors should be considered when selecting a foundation model for a text generation task? (Select 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
✓
Context window length
Context window length (A) is critical because it determines the maximum number of tokens the model can process in a single input-output sequence. For text generation tasks like long-form content creation or document summarization, a larger context window allows the model to maintain coherence over extended passages, directly impacting output quality and relevance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
AWS often tests the distinction between model selection criteria (e.g., context window, license, parameters) and operational or deployment factors (e.g., latency, region availability), leading candidates to confuse performance optimization with foundational model suitability.
Detailed technical explanation
How to think about this question
Context window length is measured in tokens (e.g., 2048, 4096, or 128K tokens) and directly affects the model's ability to handle long-range dependencies. For example, a model with a 2048-token window may truncate a multi-page document, losing critical context, while a 128K-token window (like in Anthropic Claude) can process entire books. The number of parameters (D) influences model capacity and expressiveness, but larger models require more compute and may not always outperform smaller, specialized models for specific tasks.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
