For monitoring Microservices, _______ is an essential practice.

  • Code Obfuscation
  • Distributed Tracing
  • Static Analysis
  • Uptime Monitoring
Distributed Tracing is essential for monitoring Microservices, allowing tracking and analysis of requests as they traverse through various services.

________ in UDDI is critical for defining the technical details of a web service.

  • bindingTemplate
  • serviceDetails
  • tModel
  • technicalDescriptor
In UDDI, the bindingTemplate is critical for defining the technical details of a web service. It specifies the technical aspects of a service, such as the access point and other relevant information necessary for service consumption.

_______ ensures the integrity and authenticity of XML messages in web services.

  • XML Encryption
  • XML Serialization
  • XML Signature
  • XML Validation
XML Signature is used to ensure the integrity and authenticity of XML messages in web services.

Which technology allows clients to query exactly what they need and nothing more?

  • GraphQL
  • REST
  • SOAP
  • XML-RPC
GraphQL allows clients to query and retrieve exactly the data they need, providing more flexibility compared to other technologies.

_______ is a common mechanism used in OAuth for client authentication.

  • API Key
  • Client Credentials
  • JWT
  • SAML
In OAuth, the Client Credentials grant type is a common mechanism for client authentication. It involves the client (application) presenting its credentials to the authorization server to obtain an access token. This is often used in server-to-server communication or when the client is a trusted entity.

The process of isolating the container's view of the operating system, including file systems and network interfaces, is known as _______ in Docker.

  • Containerization
  • Isolation
  • Segregation
  • Virtualization
The process is known as isolation in Docker, where the container has its own isolated view of the operating system.

SAML is mainly used for which type of authentication?

  • Biometric Authentication
  • Captcha-based Authentication
  • Single Sign-On (SSO)
  • Two-Factor Authentication (2FA)
SAML (Security Assertion Markup Language) is mainly used for Single Sign-On (SSO) authentication.

In web services, how is a '404 Not Found' error typically resolved?

  • Changing the programming language
  • Ignoring the error
  • Increasing server load capacity
  • Providing a valid endpoint URL
A '404 Not Found' error in web services is typically resolved by providing a valid endpoint URL that the service can locate.

In token-based authentication, what is the main advantage of using tokens over traditional credentials?

  • Compatibility with legacy systems
  • Simplicity in implementation
  • Stateless nature and scalability
  • Strong encryption of credentials
Token-based authentication offers a stateless and scalable solution, as tokens carry the necessary information and reduce the need for server-side storage of session data.

In a scenario involving microservices architecture, why would JWT be preferred over traditional session-based authentication?

  • Compatibility with legacy systems
  • Simplicity and ease of implementation
  • Stateless nature and scalability
  • Tight coupling between services
JWT is preferred in microservices architectures due to its stateless nature, making it scalable and efficient. It eliminates the need for centralized session management.
