- A
Create an action group that includes an OpenAPI schema describing the flight API and a Lambda function to invoke it
Action groups define the tools available to an Agent. The Agent uses the OpenAPI schema to understand the API and triggers the Lambda to execute the call.
- B
Add the API documentation as a context document in the Agent's instructions
Why wrong: Context documents only provide background info; they do not allow the Agent to make live API calls.
- C
Configure the Agent to use Amazon Kendra to index the API documentation
Why wrong: Kendra is for enterprise search, not for enabling live API calls from an Agent.
- D
Hard‑code the API endpoint in the Agent's prompt using a system message
Why wrong: Hard‑coding in a prompt cannot execute API calls; the Agent lacks the tool‑use mechanism.
AIF-C01 Practice Question: A developer is building an Amazon Bedrock Agent…
This AIF-C01 practice question tests your understanding of aif-c01 exam topics. 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 developer is building an Amazon Bedrock Agent to automate multi‑step workflows like booking flights and hotels. The Agent needs to call an external flight reservation API. How should the developer expose this API to the Agent?
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
Create an action group that includes an OpenAPI schema describing the flight API and a Lambda function to invoke it
Amazon Bedrock Agents use action groups to define external APIs that the agent can invoke. An action group requires an OpenAPI schema (to describe the API operations and parameters) and a Lambda function (to execute the actual API call). This allows the agent to dynamically select and call the flight reservation API during multi-step workflows.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why this is correct
Action groups define the tools available to an Agent. The Agent uses the OpenAPI schema to understand the API and triggers the Lambda to execute the call.

- ✗
Add the API documentation as a context document in the Agent's instructions
Why it's wrong here
Context documents only provide background info; they do not allow the Agent to make live API calls.
- ✗
Configure the Agent to use Amazon Kendra to index the API documentation
Why it's wrong here
Kendra is for enterprise search, not for enabling live API calls from an Agent.
- ✗
Hard‑code the API endpoint in the Agent's prompt using a system message
Why it's wrong here
Hard‑coding in a prompt cannot execute API calls; the Agent lacks the tool‑use mechanism.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think providing API documentation as context (Option B) is sufficient, but they miss that Bedrock Agents require an action group with both a schema and a Lambda function to actually invoke the API.
Detailed technical explanation
How to think about this question
Under the hood, the OpenAPI schema (in JSON or YAML format) defines endpoints, request/response structures, and authentication methods. The Lambda function acts as the bridge, receiving a structured request from the agent (with parameters extracted from the user's input) and returning a formatted response. In real-world scenarios, the Lambda function can also handle error retries, API key rotation, and logging, which are critical for production-grade flight booking systems.
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.
