What is the role of WSDL in a SOAP web service?
- WSDL defines the security protocols for a web service
- WSDL describes the structure and functionality of a web service
- WSDL handles the actual data transmission in SOAP
- WSDL is not related to SOAP
WSDL (Web Services Description Language) is used in SOAP web services to describe the structure and functionality of the service, including its operations and message formats.
When implementing HTTPS, what type of encryption is typically used?
- AES
- MD5
- RSA
- SSL/TLS
HTTPS typically uses the SSL/TLS protocol for secure communication over the web.
To prevent second-order SQL Injection, it is important to perform input validation at the _______ stage.
- Application
- Database
- Middleware
- Presentation
Input validation at the database stage is crucial to prevent second-order SQL Injection attacks, where malicious data is stored and later used to exploit vulnerabilities.
In integration testing, _______ is used to validate the interaction between different layers of a web application.
- Drivers
- Fuzzing
- Mocking
- Stubs
Stubs are used in integration testing to validate the interaction between different layers of a web application.
For a company using both SOAP and RESTful services, what strategy ensures optimal interoperability?
- Choosing SOAP for all communication
- Implementing a mediation layer
- Keeping SOAP and REST services separate
- Standardizing only on RESTful services
To ensure optimal interoperability in a company using both SOAP and RESTful services, implementing a mediation layer is a common strategy. The mediation layer acts as a translator, enabling communication between SOAP and RESTful services by converting messages and ensuring compatibility. This approach allows the coexistence of different service types without compromising interoperability.
What is the role of unit tests in ensuring the backward compatibility of web services?
- Causes backward compatibility issues
- Helps detect and prevent regressions in functionality
- Is not related to backward compatibility
- Only useful for new features
Unit tests play a crucial role in ensuring the backward compatibility of web services by helping detect and prevent regressions in functionality during updates.
The HTTP method _______ is used in RESTful services to request a representation of the specified resource requests without returning the entity-body.
- GET
- HEAD
- POST
- PUT
In RESTful services, the HTTP method HEAD is used to request a representation of the specified resource without returning the entity-body. The server responds with headers containing information about the resource, allowing clients to check its existence and obtain metadata without the actual data.
In a scenario where an application requires rapid scaling based on demand, which feature of Kubernetes is most beneficial?
- Container Registry
- Docker Compose
- Horizontal Pod Autoscaling
- Kubernetes ConfigMaps
Horizontal Pod Autoscaling in Kubernetes allows automatic scaling of the number of pods based on observed CPU utilization or other custom metrics, ensuring optimal resource allocation.
For safe and read-only operations, RESTful services commonly use the _______ method.
- DELETE
- GET
- POST
- PUT
For safe and read-only operations in RESTful services, the GET method is commonly used. The GET method requests data from a specified resource and should not cause any side effects on the server. It is suitable for operations where data retrieval is the primary goal.
What role does SOC 2 play in the compliance of web services?
- Assessing Service Organization Controls
- Certifying Open Source Components
- Optimizing Server Configuration
- Standardizing Object-oriented Code
SOC 2 plays a crucial role in web services compliance by assessing and ensuring the effectiveness of service organization controls related to security, availability, processing integrity, confidentiality, and privacy.
