In WS-Security, what is the role of XML Encryption?

  • Compressing the XML document
  • Encrypting specific elements in the XML
  • Encrypting the entire XML document
  • Signing the XML document
In WS-Security, XML Encryption is used to encrypt specific elements within an XML document. This selective encryption enhances security by allowing sensitive data to be protected while leaving other parts of the document intact. It provides a granular approach to securing information in transit within web services.

XML uses _______ to define the structure of the data it encloses.

  • Attributes
  • Brackets
  • Elements
  • Tags
XML uses tags to define the structure of the data it encloses. Tags are the building blocks of an XML document, enclosing data and providing a hierarchical structure that is easily readable and understandable.

A web service is experiencing increased load and slowing down. What debugging strategy is most appropriate to identify bottlenecks?

  • Code review
  • Performance profiling
  • Security testing
  • Unit testing
Performance profiling is an appropriate debugging strategy to identify bottlenecks in a web service experiencing increased load and slowing down. It helps analyze the performance of different components.

In web services, a TLS handshake is used for what purpose?

  • Checking the server's availability
  • Establishing a secure connection between client and server
  • Sending encrypted data
  • Terminating the connection after data transmission
The TLS handshake is used to establish a secure connection between the client and the server, ensuring encrypted communication.

In a scenario where an external API is unavailable for testing, what is the most effective alternative?

  • Delaying testing until API is available
  • Mocking the API responses
  • Skipping API testing
  • Using live production API
Mocking the API responses allows testing to proceed even when the actual API is unavailable, simulating its behavior for testing purposes.

GraphQL queries can reduce over-fetching issues, common in _______ based APIs.

  • HTTP
  • REST
  • RPC
  • SOAP
GraphQL queries are efficient in reducing over-fetching issues commonly associated with REST-based APIs.

How does Microservices Architecture differ from a monolithic architecture in handling business functionalities?

  • Independent deployability of services
  • Limited scalability
  • Single codebase for all services
  • Tight coupling of services
Microservices Architecture allows for independent deployability of services, enabling flexibility and scalability in handling business functionalities.

_______ 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.
