An IT integration team followed an API-led connectivity approach to implement an order-fulfillment business process It created an order processing API that coordinates stateful interactions with a variety of microservices that validate, create and fulfill new product orders.
Which interaction composition pattern did the integration architect who designed this order processing API use?

  1. Multicasting
  2. Orchestration
  3. Streaming
  4. Aggregation

Answer(s): B

Explanation:

In an API-led connectivity approach, different APIs are layered to provide modular and reusable services. For an order processing API that coordinates stateful interactions with various microservices, the integration architect used the orchestration interaction composition pattern.
Here's a step-by-step explanation:
Understanding Orchestration:
Definition: Orchestration involves coordinating multiple services to achieve a complex business workflow. Unlike choreography, which relies on each service knowing its part, orchestration uses a central controller to manage the interactions.

Role of the Orchestrator: The orchestrator manages the execution sequence, handles the state, and ensures all the necessary steps are completed successfully.
Order Processing API:
API-Led Connectivity: An order processing API, following API-led connectivity, sits in the Process layer, handling complex business processes and logic. Stateful Interactions: Orchestration is particularly suitable for stateful interactions where the process needs to remember the state between steps, such as validating an order, creating it, and fulfilling it.
Implementation Steps:
Microservices Interaction: The order processing API interacts with various microservices:
Validation Microservice: Checks the validity of the order details. Creation Microservice: Creates the order in the system. Fulfillment Microservice: Manages the order fulfillment process.

Coordination: The API orchestrates these steps, ensuring each one completes successfully before moving to the next, handling exceptions, and maintaining the state of the process.

An organization's IT team must secure all of the internal APIs within an integration solution by using an API proxy to apply required authentication and authorization policies Which integration technology, when used for its intended purpose should the team choose to meet these requirements if all other relevant factors are equal?

  1. Integration Platform-as-a-Service (iPaaS)
  2. API Management (APIM)
  3. Robotic Process Automation (RPA)
  4. Electronic Data Interchange (EDI)

Answer(s): B

Explanation:

Securing internal APIs within an integration solution is critical for protecting sensitive data and ensuring proper access controls. The use of API proxies to apply authentication and authorization policies is a best practice in API security. Here's a detailed explanation:
API Management (APIM):
Purpose: API Management platforms are designed specifically to manage, secure, and monitor APIs. They provide tools for designing, publishing, securing, and analyzing APIs.
Key Features:
Security: APIM platforms offer robust security features such as OAuth, JWT, API keys, and IP whitelisting to authenticate and authorize API consumers. API Proxies: They allow the creation of API proxies which act as intermediaries between the client and the backend service. This enables enforcing security policies without modifying the backend API.
Implementation:
Authentication and Authorization Policies: Using APIM, the IT team can easily configure policies for authentication (e.g., OAuth 2.0) and authorization to control access to APIs. Policy Enforcement: These policies are enforced at the API proxy level, ensuring that only authenticated and authorized requests reach the backend services. Monitoring and Analytics: APIM platforms provide detailed analytics and monitoring capabilities to track API usage, detect anomalies, and ensure compliance.

What is an advantage of using OAuth 2 0 client credentials and access tokens over only API keys for API authentication?

  1. If the access token is compromised, the client credentials do not have to be reissued
  2. If the client ID is compromised it can be exchanged for an API key
  3. If the access token is compromised it can be exchanged for an API key
  4. If the client secret is compromised, the client credentials do not have to be reissued

Answer(s): A

Explanation:

OAuth 2.0 provides a more secure and flexible way of handling API authentication compared to API keys. Here's a detailed explanation of the advantage mentioned:
OAuth 2.0 Client Credentials Grant:
How It Works: In this flow, a client application uses its client ID and client secret to obtain an access token from the authorization server.
Access Tokens: These tokens are short-lived and used to authenticate API requests.
Security Advantages:
Token Compromise: If an access token is compromised, it only grants limited access because it has a short lifespan and can be easily revoked.
Client Credentials: The client credentials (client ID and secret) are not exposed during API calls, reducing the risk of them being compromised.

Token Refresh: New tokens can be obtained without exposing the client credentials again.
Comparison with API Keys:
API Keys: If an API key is compromised, it often provides long-term access without expiration. Revoking the API key impacts all users or applications using it. OAuth Tokens: Compromised tokens can be individually revoked without needing to change the client credentials, minimizing disruption.
