Question 1

An integration architect is designing an API that must accept requests from API clients for both XML and JSON content over HTTP/1 1 by default.
Which API architectural style when used for its intended and typical purposes, should the architect choose to meet these requirements?

Correct Answer: C
REST (Representational State Transfer) is an architectural style commonly used for designing networked applications, particularly APIs that need to handle multiple content types over HTTP. Here's a detailed explanation:
* Content Negotiation:
* Definition: REST APIs support content negotiation, allowing clients to request either XML or JSON formats by setting theAcceptheader in HTTP requests.
* Flexibility: This capability makes REST ideal for scenarios where an API needs to serve multiple content types.
* HTTP Protocol:
* Usage: REST APIs operate over HTTP/1.1, making them compatible with web standards and easily accessible by various clients (browsers, mobile apps, etc.).
* Methods: Supports standard HTTP methods like GET, POST, PUT, DELETE, allowing for CRUD operations.
* Advantages:
* Stateless: Each request from a client to server must contain all the information needed to understand and process the request.
* Scalability: RESTful services can handle a high load of requests efficiently.

Question 2

A Kubernetes controller automatically adds another pod replica to the resource pool in response to increased application load Which scalability option is the controller implementing?

Correct Answer: A
Kubernetes offers several scalability options to handle varying application loads. The scenario described involves adding another pod replica in response to increased load, which is a form of horizontal scaling. Here' s a detailed explanation:
* Horizontal Scaling:
* Definition: Horizontal scaling, also known as scaling out, involves adding more instances (pods) to distribute the load and increase capacity.
* Implementation in Kubernetes: Kubernetes uses controllers like the Horizontal Pod Autoscaler (HPA) to automatically adjust the number of pod replicas based on observed CPU utilization or other select metrics.
* Benefits:
* Load Distribution: By adding more pod replicas, the load is evenly distributed, reducing the risk of any single pod being overwhelmed.
* Fault Tolerance: Horizontal scaling enhances fault tolerance and availability, as multiple pod replicas can handle requests if one fails.
* Automatic Scaling:
* Kubernetes Controller: The HPA continuously monitors the application load and adjusts the number of pod replicas accordingly, ensuring optimal performance.

Question 3

A developer is examining the responses from a RESTful web service that is compliant with the Hypertext Transfer Protocol (HTTP/1 1) as defined by the Internet Engineering Task Force (IETF).
In this HTTP/1 1-comphanl web service, which class of HTTP response status codes should be specified to indicate when client requests are successfully received, understood and accepted by the web service?

Correct Answer: A

Question 5

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

Correct Answer: A
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.
