Identify the option that is not a type of web service architecture.

1. RESTful Web Services

2. SOAP (Simple Object Access Protocol)

3. JSON-RPC (Remote Procedure Call)

4. GraphQL (Graph Query Language)

Explanation:

Options A, B, and D are different types of web service architectures commonly used for communication between systems. JSON-RPC is a protocol for making remote procedure calls using JSON over HTTP, rather than a distinct architecture like RESTful, SOAP, or GraphQL.

Choose the option that is not a data format commonly used in web services.

1. HTML (Hypertext Markup Language)

2. YAML (YAML Ain't Markup Language)

3. JSON (JavaScript Object Notation)

4. XML (eXtensible Markup Language)

Explanation:

Options B,C and D are data formats commonly used for data interchange in web services. HTML is primarily used for creating web pages and displaying content in browsers, rather than data interchange between systems.

Identify the option that is not an HTTP method commonly used in RESTful web services.

1. PUSH

2. DELETE

3. POST

4. GET

Explanation:

Options B, C, and D are HTTP methods commonly used in RESTful web services (GET, POST, and DELETE respectively). PUSH is not a standard HTTP method; instead, PUT is commonly used in RESTful services to update resources.

Choose the option that is not a characteristic of RESTful web services.

1. Stateless

2. Caching

3. Contract-first approach

4. Protocol-agnostic

Explanation:

Options A, B, and D are characteristics of RESTful web services. A contract-first approach is more commonly associated with SOAP-based web services, where the service contract (WSDL) is defined before implementation, unlike RESTful services which are typically more flexible in defining contracts.

Identify the option that is not a benefit of using web services.

1. Interoperability

2. Tight coupling

3. Reusability

4. Scalability

Explanation:

Options A, C, and D are benefits of using web services (Interoperability, Reusability, and Scalability respectively). Tight coupling, where components are highly dependent on each other, is not a benefit but a disadvantage in web services architecture.
