A developer is designing an API endpoint for updating user profiles where partial update is expected. Which HTTP method should be used?
- PATCH
- POST
- PUT
- UPDATE
When a partial update is expected in an API endpoint, the appropriate HTTP method to use is PATCH. PATCH is designed to apply partial modifications to a resource, making it suitable for updating specific fields in a user profile without affecting the entire resource.
WSDL documents are formatted in which language?
- HTML
- JSON
- Java
- XML
WSDL documents are formatted in XML (eXtensible Markup Language), providing a standardized way to describe web services.
For a SOAP service that requires dynamic discovery of other services, what technology is typically employed?
- Representational State Transfer (REST)
- Simple Object Access Protocol (SOAP)
- Universal Description, Discovery, and Integration (UDDI)
- Web Services Description Language (WSDL)
Universal Description, Discovery, and Integration (UDDI) is a technology commonly employed for dynamic service discovery in SOAP-based architectures. UDDI provides a standard way for services to be published and discovered dynamically, allowing SOAP services to locate and interact with other services in a flexible and scalable manner.
For a company migrating to a microservices architecture, how should they approach testing for each individual service?
- Isolated testing for each service
- Only perform unit testing
- Skip testing for services
- Testing all services together
Testing each microservice in isolation is crucial to ensure that they function correctly and maintain independence in a microservices architecture.
Web services must adhere to _______ to ensure data privacy and security.
- HTTP
- JSON
- SSL/TLS
- XML
Web services must adhere to SSL/TLS to ensure data privacy and security through secure communication.
In AWS, what is the primary function of Elastic Load Balancing?
- Configuring network security groups
- Deploying and managing virtual machines
- Distributing incoming application traffic across multiple targets
- Storing and retrieving data in the cloud
Elastic Load Balancing in AWS is used to distribute incoming application traffic across multiple targets, ensuring high availability and fault tolerance.
In a cloud-native approach, _______ helps in defining and managing complex architectures.
- Infrastructure as Code (IaC)
- Manual configuration
- Static resource management
- Traditional deployment
In a cloud-native approach, Infrastructure as Code (IaC) is used to define and manage complex architectures, providing agility and scalability.
In which type of web service architecture is UDDI most commonly used?
- Remote Procedure Call (RPC)
- Representational State Transfer (REST)
- Service-Oriented Architecture (SOA)
- Simple Object Access Protocol (SOAP)
UDDI is most commonly used in Service-Oriented Architecture (SOA), providing a directory for businesses to publish and discover services in a standardized way.
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.
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.
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.
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.
