AIF-C01 Practice Question: Using Amazon Bedrock Agents to build a travel…
A company is using Amazon Bedrock Agents to build a travel booking assistant that can search for flights, book hotels, and answer questions about travel policies. Which TWO components are required to enable the agent to call external services? (Select TWO.)
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
✓
Action group with API schema
Action groups define the APIs (e.g., flight search, hotel booking) that the agent can invoke. A Lambda function provides the business logic to execute those API calls. Together they enable the agent to interact with external services.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Action group with API schema
Why this is correct
Action groups define the set of operations (APIs) the agent can call.
- ✓
AWS Lambda function
Why this is correct
Lambda functions provide the implementation for each action, such as calling external APIs.
- ✗
Amazon DynamoDB table
Why it's wrong here
While the Lambda may use DynamoDB, it is not a required component for defining agent actions.
- ✗
Amazon SageMaker endpoint
Why it's wrong here
SageMaker endpoints are for hosting custom models, not for agent actions.
- ✗
Bedrock Knowledge Base
Why it's wrong here
A Bedrock Knowledge Base provides a repository of static documents for retrieval-augmented generation (RAG), not the ability to execute live API calls to external services. It is tempting because it can store travel policy documents, which an agent might query for answers, but it lacks the action groups or Lambda functions required to invoke external flight or hotel booking systems. It would be correct only if the agent needed to answer policy questions from a fixed corpus, not to perform transactional operations.
