What is the primary use of Postman in web services testing?

  • Creating databases
  • Generating random data
  • Graphic design in web development
  • Sending HTTP requests and testing APIs
Postman is primarily used for sending HTTP requests and testing APIs, allowing developers to interact with web services.

The _______ protocol is deprecated in favor of TLS for securing web services.

  • FTP
  • HTTP
  • SMTP
  • SSL
The SSL (Secure Sockets Layer) protocol is deprecated in favor of TLS (Transport Layer Security) for securing web services.

RESTful APIs use HTTP _______ to perform operations on resources.

  • Actions
  • Methods
  • Requests
  • Verbs
RESTful APIs use HTTP methods, also known as HTTP verbs, to perform operations on resources. Common methods include GET, POST, PUT, DELETE, etc.

The use of _______ ensures that web services can be accessed regardless of programming language or platform.

  • CORBA (Common Object Request Broker Architecture)
  • HTTP (Hypertext Transfer Protocol)
  • URI (Uniform Resource Identifier)
  • WSDL (Web Services Description Language)
The use of URI (Uniform Resource Identifier) ensures that web services can be accessed regardless of programming language or platform. URIs provide a standardized way to identify and locate resources on the web, promoting a language-agnostic and platform-independent approach.

How does JWT differ from session-based authentication in terms of scalability?

  • JWTs and session-based authentication have similar scalability
  • JWTs are stateless and don't require server-side storage
  • JWTs require frequent server-side storage updates
  • Session-based authentication is more scalable
JWTs (JSON Web Tokens) are stateless, meaning they don't require server-side storage, making them more scalable than session-based authentication, which relies on server-side storage.

A financial service is transmitting sensitive data over the web. Which encryption technique should be prioritized for data protection?

  • AES
  • Blowfish
  • RSA
  • Triple DES
In the context of transmitting sensitive data, Advanced Encryption Standard (AES) is commonly prioritized for its robust security.

The _______ algorithm in TLS is used for key agreement and establishment.

  • AES
  • HMAC
  • RSA
  • SHA-256
The RSA algorithm in TLS is utilized for key agreement and establishment during the handshake process.

_______ versioning involves maintaining multiple versions of the service at the same time.

  • Concurrent
  • Horizontal
  • Parallel
  • Vertical
Concurrent versioning involves maintaining multiple versions of the service at the same time.

Which approach uses multiple endpoints for different resources?

  • GraphQL services
  • JSON-RPC services
  • RESTful services
  • SOAP services
RESTful services commonly use multiple endpoints for different resources, providing a clear and resource-centric structure.

Which type of testing is facilitated by the mocking service in SOAP UI?

  • Load testing for APIs
  • Security testing for APIs
  • Simulating the behavior of a web service
  • Unit testing for API components
The mocking service in SOAP UI facilitates simulating the behavior of a web service, allowing for testing interactions without invoking the actual service.
