How does the implementation of DevOps practices impact the lifecycle of web services?

  • Accelerated development and deployment cycles
  • Increased manual interventions in deployment
  • Limited collaboration between development and operations teams
  • Reduced automation in testing
Implementation of DevOps practices accelerates development and deployment cycles, promoting collaboration and automation throughout the lifecycle of web services.

How should a unit test be structured when testing a web service for compliance with security protocols?

  • Focus solely on input validation
  • Ignore encryption and focus on decryption
  • Include test cases for authentication and authorization
  • Prioritize performance testing
When testing a web service for compliance with security protocols, the unit test should be structured to include test cases for authentication and authorization to ensure secure access to the service.

To identify the root cause of an error, developers often rely on _______ files generated by the web service.

  • Configuration
  • Database
  • Log
  • XML
Developers often rely on log files generated by the web service to identify the root cause of errors.

In advanced unit testing, _______ is used to ensure that the web service can handle various types of failure scenarios.

  • Code coverage
  • Fault injection
  • Load testing
  • Static analysis
Fault injection is used in advanced unit testing to simulate various failure scenarios and ensure the robustness of the web service.

In web security, XSS stands for what?

  • Cross-Site Scripting
  • Extended Server Software
  • External System Support
  • XML Security Services
XSS stands for Cross-Site Scripting, a type of security vulnerability where attackers inject malicious scripts into web pages viewed by other users.

_______ is a key factor in achieving scalability and flexibility in SOA.

  • Centralized Architecture
  • Data Encryption
  • Loose Coupling
  • Object-Relational Mapping (ORM)
Loose coupling is a key factor in achieving scalability and flexibility in Service-Oriented Architecture (SOA). It allows services to operate independently, promoting modularity and ease of updates without affecting the entire system. Loose coupling enhances adaptability and scalability in SOA.

In OAuth, the _______ acts as an intermediary on behalf of the end-user.

  • Authorization Server
  • Client Credentials
  • Resource Server
  • Token Endpoint
In OAuth, the Authorization Server acts as an intermediary on behalf of the end-user. It is responsible for authenticating the user and obtaining their consent to grant access. Once authorized, it issues access tokens that the client can use to access protected resources on behalf of the end-user.

In GraphQL, what does the term "schema" refer to?

  • A visual representation of data
  • Defines the types and relationships in a data graph
  • The process of optimizing queries
  • The programming language used in GraphQL
In GraphQL, a "schema" defines the types and relationships in a data graph, specifying the structure of the data that can be queried.

In a scenario where a SOAP service needs to handle high-volume transactions, what architectural element is most critical?

  • Asynchronous Processing
  • Caching Strategies
  • Load Balancing
  • Throttling Mechanism
In high-volume transaction scenarios, Load Balancing is crucial for distributing the incoming requests evenly across multiple servers. This helps improve scalability and ensures that no single server is overloaded, thereby optimizing the overall performance of the SOAP service.

GraphQL is mainly used in web services for what purpose?

  • Data storage in databases
  • Efficient data querying and manipulation
  • Real-time video streaming
  • Voice recognition
GraphQL is used for efficient querying and manipulation of data, allowing clients to request only the data they need.
