- A
Knowledge Bases for product information
Why wrong: Knowledge Bases are for static documents, not transactional API calls.
- B
Lambda functions to execute the API calls
Lambda functions implement the business logic to call inventory and payment APIs.
- C
A vector store to cache transaction data
Why wrong: Vector stores are for similarity search, not for transactional data storage.
- D
Action groups with API schemas
Action groups define the inventory and payment APIs that the agent can invoke.
- E
Guardrails to filter sensitive data
Why wrong: Guardrails are not required for the agent to perform actions; they are optional for content safety.

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 using Bedrock Agents to create an order management assistant. The agent needs to check inventory and process payments. Which TWO components are required to enable these capabilities?
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
✓
Lambda functions to execute the API calls
Option B is correct because Lambda functions are required to execute the business logic for API calls, such as checking inventory or processing payments. In Bedrock Agents, Lambda functions serve as the compute layer that processes the agent's requests and returns results, enabling the agent to interact with external systems like inventory databases or payment gateways.
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
A common pitfall in Bedrock Agents is confusing Knowledge Bases (used for static information retrieval like product details) with Action Groups (used for dynamic real-time actions like inventory checks and payment processing). Candidates often select Knowledge Bases for capabilities that require API calls, but those rely on Action Groups + Lambda.

Vector stores are for similarity search, not for transactional data storage.
Detailed technical explanation
How to think about this question
Action groups define the set of operations an agent can perform, using OpenAPI schemas to describe the APIs. Lambda functions are invoked by the agent to execute these operations, handling authentication, request/response transformation, and error handling. In a real-world scenario, the Lambda function might call a REST API for inventory checks and a separate payment gateway API, with the action group schema defining the input/output parameters for each.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
