The _______ element in WSDL defines the operations offered by the service.
In WSDL, the element defines the operations offered by the service. It contains a set of abstract operations, each representing a message exchange pattern.
A software development team is deploying a complex application with multiple interdependent services. What Docker feature would best handle this setup?
- Docker Compose
- Docker Hub
- Docker Swarm
- Dockerfile
Docker Compose is a tool for defining and running multi-container Docker applications. It allows the definition of services, networks, and volumes in a single file, simplifying the deployment of complex, interdependent services.
To manage state in stateless SOAP services, the technique of _______ is commonly used.
- Cookies
- Session Management
- WS-ReliableMessaging
- WS-Security
In stateless SOAP services, managing state is essential. Session management is a common technique employed to maintain state across multiple requests. It allows for the persistence of information related to a particular session, ensuring continuity and coherence in interactions with the stateless service.
RESTful services are stateless. What does this imply in terms of client-server communication?
- Each request from a client contains all the information needed for the server to fulfill it.
- The client must include a state identifier in each request.
- The server retains no information about the client's state between requests.
- The server stores the client's state for future interactions.
Stateless in REST means that the server does not retain any information about the client's state between requests. Each request from a client to the server must contain all the information needed to understand and fulfill the request, promoting scalability and simplicity in the communication model.
In a Continuous Integration/Continuous Deployment (CI/CD) pipeline, how do mock services enhance the testing process?
- Automating database migrations
- Enabling parallel testing
- Enhancing user interface design
- Reducing dependencies on external services
Mock services enhance the testing process in CI/CD pipelines by reducing dependencies on external services, enabling faster and more reliable testing without relying on the availability of real services.
Which security consideration is most critical when implementing OAuth in a web service?
- Allowing unlimited token validity periods
- Properly validating and securing access tokens
- Storing user credentials in plaintext
- Using plaintext for token transmission
The most critical security consideration in implementing OAuth is properly validating and securing access tokens. Access tokens are a key component in OAuth, and ensuring their integrity and validity is crucial for preventing unauthorized access. This involves token validation, protection against token leakage, and secure handling of tokens throughout the authentication process.
_______ is used in web services to describe the data structure in a detailed manner.
- HTML
- JSON
- XML
- YAML
XML is commonly used in web services to describe the data structure in a detailed and standardized manner, facilitating data interchange between systems.
In a scenario where a web service handles sensitive data, what TLS feature should be prioritized to prevent data breaches?
- Heartbeat Extension
- Perfect Forward Secrecy
- SSLv2 Compatibility
- Session Resumption
Prioritize Perfect Forward Secrecy (PFS) to ensure that even if a long-term key is compromised, past communication remains secure.
A web application suffers a data breach due to an SQL Injection. Which aspect of security was most likely overlooked?
- Authentication
- Encryption
- Input validation
- Session management
The data breach due to SQL Injection indicates a lack of proper input validation, allowing malicious SQL queries to be executed.
The process of finding suitable web services in UDDI is known as _______.
- UDDIsearch
- serviceDiscovery
- serviceMatching
- webServiceIdentification
The process of finding suitable web services in UDDI is known as serviceMatching. During service matching, UDDI compares the technical and business criteria provided by the requester with the information stored in the registry to identify and return relevant services.
