CCAO-F Claude Model Fundamentals Practice Question
A developer is using the Anthropic Messages API with Claude 3 Opus to build a multi-turn technical support chatbot. The conversation history is growing large, and they want to reduce token usage while preserving the most relevant context. They decide to implement a sliding window that keeps only the last N turns. What is a potential drawback of this approach that they should consider?
⚠ Common exam trap
The trap here is believing that Claude retains memory of dropped turns or automatically summarizes them, when in fact the model only sees the current request payload.

Correct answer & explanation
✓
The sliding window may discard important early instructions or context that Claude needs to maintain consistent behavior throughout the conversation.
A sliding window reduces token usage by dropping older turns, but it also removes early context that may be essential for consistent behavior. Claude does not retain memory outside the provided messages, so once early instructions or facts are dropped, they are unavailable. The developer should consider summarization or selective retention of important early context to balance token efficiency with conversational coherence.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The sliding window will increase latency because Claude must reprocess the entire conversation history on each turn.
Why it's wrong here
A sliding window reduces the amount of text sent in each request, which generally lowers latency compared to sending the full history. While Claude does process the provided input, a smaller input means less processing. The claim that it increases latency is the opposite of the typical effect. Latency could still be affected by other factors, but the sliding window itself is a mitigation, not a cause of increased latency.
- ✓
The sliding window may discard important early instructions or context that Claude needs to maintain consistent behavior throughout the conversation.
Why this is correct
A sliding window keeps only recent turns, so any critical instructions or facts established early in the conversation are dropped once they fall outside the window. Claude has no memory beyond the supplied context, so it may forget user preferences, prior constraints, or key details. This can lead to inconsistent or incorrect responses. The developer should summarize or selectively retain important early context rather than blindly truncating.
- ✗
Claude will automatically summarize the dropped turns and include the summary in its response, which may introduce hallucinations.
Why it's wrong here
Claude does not automatically summarize or retain information that is not present in the conversation history. The model only sees the messages provided in the current API call. It cannot summarize dropped turns because it has no access to them. Any summarization must be implemented by the developer and explicitly included in the prompt. This option misattributes a developer responsibility to the model.
- ✗
The sliding window will cause Claude to exceed the model's maximum context window because older turns are still counted in the token limit.
Why it's wrong here
A sliding window explicitly removes older turns from the request, which reduces the number of input tokens and helps stay within the context window. It does not cause the context window to be exceeded; rather, it is a technique to avoid exceeding it. The concern about older turns still being counted is incorrect because they are not included in the API call once dropped.
