- A
Switch to a model with a 100,000 token context window like Claude 3
Why wrong: While possible, it may be costlier and not address the core issue of long document handling; also, the model may still miss details. Chunking is more reliable.
- B
Truncate the ticket to 4,000 tokens before sending to the model
Why wrong: Truncation risks losing key details entirely.
- C
Split the ticket into chunks of 3,500 tokens, summarize each chunk, then summarize the summaries
Chunking preserves all information and the hierarchical summarization captures key details.
- D
Use Amazon Bedrock's Converse API with the entire 8,000-token ticket
Why wrong: Titan Text Express has a context window limit; exceeding it causes truncation or errors regardless of API.

AIF-C01 Generative AI and Foundation Models Practice Question
This AIF-C01 practice question tests your understanding of generative ai and foundation models. 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.
A company uses Amazon Titan Text Express to summarize customer support tickets. The model often misses key details when the ticket exceeds 4,000 tokens. The team needs to process tickets up to 8,000 tokens without losing important information. Which strategy is MOST effective?
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
✓
Split the ticket into chunks of 3,500 tokens, summarize each chunk, then summarize the summaries
Option C is correct because it uses a hierarchical summarization approach: splitting the 8,000-token ticket into chunks within the model's 4,000-token limit, summarizing each chunk independently, then combining those summaries into a final summary. This preserves key details across the entire ticket without exceeding the model's context window, which is a common technique for handling long documents with fixed-context models.
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
The trap here is that candidates may assume the Converse API (Option D) can handle longer inputs because it supports multi-turn conversations, but it does not change the underlying model's token limit, leading to silent data loss.
Detailed technical explanation
How to think about this question
Amazon Titan Text Express has a fixed maximum input token limit of 4,000 tokens, and any input exceeding this is silently truncated, losing data beyond that boundary. The hierarchical summarization technique (chunking and merging) leverages the model's strength in summarization within its context window, and is a standard pattern in production systems for processing long documents with models that have limited context lengths. In practice, chunk overlap (e.g., 100 tokens) is often added to avoid cutting off sentences or key context at chunk boundaries.
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.
