What is the main difference between SSL and TLS protocols in web services?
- SSL is for secure websites, and TLS is for non-secure websites
- SSL is newer than TLS and has more features
- TLS is the successor of SSL and provides better security
- There is no difference; they are used interchangeably
TLS is the successor to SSL and provides improvements in security. It's important to use TLS for secure data transmission in modern web services.
How does versioning in SOAP differ from RESTful services?
- RESTful services do not support versioning
- RESTful services often rely on URI versioning
- SOAP typically uses explicit versioning in the message format
- SOAP uses header information for versioning
SOAP and RESTful services differ in versioning approaches. SOAP often uses explicit versioning in the message format, while RESTful services commonly employ URI versioning.
Which HTTP method is used for retrieving data in a RESTful service?
- DELETE
- GET
- POST
- PUT
The GET method in RESTful services is used for retrieving data. It is a safe and idempotent operation that fetches information without causing any side effects on the server.
The concept of _______ in versioning allows users to transition smoothly to newer versions.
- Backward Compatibility
- Forward Compatibility
- Service Compatibility
- Version Compatibility
The concept of Forward Compatibility in versioning allows users to transition smoothly to newer versions.
What is the primary benefit of Azure Kubernetes Service (AKS)?
- Exclusive support for virtual machines
- Increased network latency
- Lower storage costs
- Simplified container orchestration
Azure Kubernetes Service (AKS) provides simplified container orchestration, making it easier to deploy, manage, and scale containerized applications.
When a financial service provider uses a web service, what key compliance factor should be evaluated?
- GDPR (General Data Protection Regulation)
- HIPAA (Health Insurance Portability and Accountability Act)
- PCI DSS (Payment Card Industry Data Security Standard)
- SOX (Sarbanes-Oxley Act)
Financial service providers using web services should prioritize compliance with PCI DSS to secure payment card data.
What is the significance of following a RESTful design pattern in web service development?
- High resource utilization
- Stateless communication
- Tight coupling between components
- XML-based communication
Following a RESTful design pattern in web service development is significant for achieving stateless communication, promoting scalability and simplicity.
For a web service that needs to securely exchange sensitive data with a SOAP-based system, what security implementation is most suitable?
- JWT (JSON Web Tokens)
- OAuth 2.0
- SSL/TLS (Secure Socket Layer/Transport Layer Security)
- WS-Security
WS-Security is a standard for securing SOAP-based web services. It provides a comprehensive set of specifications for securing message integrity, confidentiality, and authentication. When dealing with sensitive data exchange in SOAP, WS-Security is a suitable choice for robust security.
In Docker, what is a 'Dockerfile' used for?
- Configuring container security policies
- Defining the structure and content of a container
- Managing Docker network configurations
- Storing container logs
A Dockerfile is used to define the structure and content of a Docker container, specifying the steps to build the container image.
In terms of API versioning, how does GraphQL differ from REST?
- GraphQL typically doesn't require versioning
- GraphQL uses URL versioning
- REST automatically handles version updates
- REST uses HTTP headers for versioning
GraphQL typically doesn't require versioning due to its flexible schema and ability to request only the needed data.
