An enterprise deploys a foundation model on Amazon Bedrock with a knowledge base. Users report that the model is returning outdated information. What is the most likely cause?
⚠ Common exam trap
Watch out — candidates often confuse model versioning (Option B) with data freshness, but the question specifically ties the symptom to the knowledge base, making the refresh cycle the critical factor.

Correct answer & explanation
✓
The knowledge base data source is not refreshed
When a knowledge base is attached to a foundation model on Amazon Bedrock, the model retrieves information from the data source to augment its responses. If the data source is not refreshed, the model will return outdated information even if the model itself is current. Option C directly addresses this by identifying the stale data source as the root cause.
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 model was fine-tuned
Why it's wrong here
Fine-tuning does not inherently cause outdated information.
- ✗
The model is not the latest version
Why it's wrong here
While a newer model might have updated training, the knowledge base is the primary source for current info.
- ✓
The knowledge base data source is not refreshed
Why this is correct
If the underlying data source hasn't been updated, the knowledge base contains stale data.
- ✗
The inference parameters are incorrect
Why it's wrong here
Inference parameters affect output style, not recency.
