Right Answer:
Microservices architecture is a software design approach where an application is built as a collection of small, independent services that communicate over APIs. Each service is responsible for a specific function and can be developed, deployed, and scaled independently.

In contrast, monolithic architecture is a traditional approach where an application is built as a single, unified unit. All components are tightly integrated and run as one process, making it harder to scale and update individual parts without affecting the whole system.

Right Answer:
To ensure compatibility between MCAL, BSW, and RTE layers, I follow these steps:

1. **Adhere to AUTOSAR standards**: Ensure all components comply with the AUTOSAR specifications.
2. **Version alignment**: Use compatible versions of MCAL, BSW, and RTE as specified in the AUTOSAR release.
3. **Interface definitions**: Clearly define and maintain consistent interfaces between layers.
4. **Configuration management**: Use the AUTOSAR configuration tools to generate and validate configurations for all layers.
5. **Testing and validation**: Conduct integration testing to verify that all layers work together as intended.
6. **Documentation**: Maintain thorough documentation of interfaces and dependencies for reference during integration.

Right Answer:
My approach to handling version control and deployment in AEM projects involves using Git for version control to manage code changes, ensuring that all code is committed to a central repository. For deployment, I utilize a CI/CD pipeline with tools like Jenkins or Adobe Cloud Manager to automate the build and deployment process, ensuring consistent and reliable deployments across environments. Additionally, I manage AEM content and configurations using packages and ensure proper versioning of these packages for smooth rollbacks if necessary.

Right Answer:
Aspects in Alfresco are reusable metadata bundles or behaviors that can be dynamically added to nodes (files or folders). They're used to:

* **Add extra properties:** Attach extra metadata fields (like "Classifiable" or "Geographic").
* **Add behavior/functionality:** Enable certain actions or rules (like versioning or workflow participation).
* **Categorize content:** Tag content with specific characteristics for searching and filtering.

Right Answer:
SELECT statements in ABAP are used to retrieve data from database tables. They allow you to specify which fields to select, from which table, and under what conditions. The basic syntax is:

```abap
SELECT field1, field2 FROM table_name WHERE condition INTO TABLE @DATA(result_table).
```

This retrieves data that meets the specified condition and stores it in an internal table.

Right Answer:
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. In APIs, JSON is commonly used to format data exchanged between a client and a server, allowing for structured data representation in requests and responses.

Right Answer:
CORS, or Cross-Origin Resource Sharing, is a security feature implemented by web browsers that allows or restricts web applications from making requests to a domain different from the one that served the web page. It affects API development by requiring developers to configure their APIs to specify which origins are allowed to access their resources, ensuring that only trusted domains can interact with the API.

Right Answer:
An API Gateway acts as a single entry point for clients to access multiple microservices, handling requests, routing them to the appropriate services, managing authentication, rate limiting, and aggregating responses.

Right Answer:
API authentication is the process of verifying the identity of a user or application trying to access an API. Common methods include:

1. **API Keys**: Unique keys provided to users to access the API.
2. **Basic Authentication**: Uses a username and password encoded in Base64.
3. **OAuth**: A token-based authentication method that allows users to grant limited access to their resources without sharing credentials.
4. **JWT (JSON Web Tokens)**: A compact, URL-safe means of representing claims to be transferred between two parties, often used for stateless authentication.
5. **HMAC (Hash-based Message Authentication Code)**: Uses a secret key to create a hash of the request, ensuring data integrity and authenticity.

Right Answer:
API documentation is a technical manual that explains how to use an API, including its endpoints, request and response formats, authentication methods, and examples. It is necessary because it helps developers understand how to integrate and interact with the API effectively, ensuring proper usage and reducing errors.

Right Answer:
SLA stands for Service Level Agreement, which is a contract that outlines the expected level of service between a service provider and a customer, including metrics for service quality, availability, and responsibilities.

Right Answer:
RAID (Redundant Array of Independent Disks) is a data storage technology that combines multiple hard drives into a single unit to improve performance, increase storage capacity, and provide redundancy for data protection.
