_______ is an advanced technique used to manage and ensure interoperability among distributed web services.
- BPEL (Business Process Execution Language)
- Enterprise Service Bus (ESB)
- JSON-RPC
- RDF (Resource Description Framework)
Business Process Execution Language (BPEL) is an advanced technique used to manage and ensure interoperability among distributed web services. BPEL provides a standard for defining and orchestrating business processes, allowing seamless coordination and communication between different services in a distributed environment.
How does containerization benefit Microservices?
- Centralized Configuration
- Monolithic Scaling
- Portability and Consistency
- Tight Integration
Containerization provides benefits like portability and consistency, allowing Microservices to be deployed consistently across various environments.
In a scenario where a web service handles real-time transactions, what encryption technique would balance security and performance?
- Chaotic Encryption
- Elliptic Curve Cryptography (ECC)
- Quantum Key Distribution (QKD)
- Stream Cipher
Elliptic Curve Cryptography (ECC) is known for providing strong security with relatively lower computational overhead, making it suitable for real-time transactions.
The process of refreshing JWTs for continued authentication is known as token _______.
- Reauthentication
- Renewal
- Revocation
- Rotation
The process of refreshing JWTs for continued authentication is known as token rotation.
How does SOAP handle security compared to REST?
- REST relies on digital signatures for secure communication
- REST uses HTTPS for secure communication
- SOAP employs WS-Security for secure communication
- SOAP relies on API keys for security
SOAP, in comparison to REST, handles security through standards like WS-Security. This includes features such as encryption, digital signatures, and authentication mechanisms, providing a comprehensive approach to secure communication between web services.
In complex web service architectures, XML _______ is used for defining the message exchange patterns.
- Blueprint
- Protocol
- Schema
- Specification
In complex web service architectures, XML Schema is used for defining the message exchange patterns.
In microservices architecture, _______ patterns help in managing errors across service boundaries.
- Circuit Breaker
- Observer
- Proxy
- Singleton
In microservices architecture, Circuit Breaker patterns are employed to manage errors across service boundaries by preventing cascading failures.
A web service needs to exchange data with multiple clients using XML. What is the best approach to ensure data consistency and validation?
- Document Object Model (DOM)
- Representational State Transfer (REST)
- Simple Object Access Protocol (SOAP)
- XML Schema Definition (XSD)
XML Schema Definition (XSD) is used to define the structure and data types of XML, ensuring consistency and validation in data exchange.
How does WSDL 2.0 differ from WSDL 1.1 in terms of HTTP binding?
- There is no difference; they both handle HTTP binding the same way
- WSDL 1.1 has better compatibility with RESTful services
- WSDL 2.0 only supports SOAP over HTTP
- WSDL 2.0 provides better support for HTTP features and methods
WSDL 2.0 enhances support for HTTP features and methods, offering improved flexibility for web services.
What is the main benefit of using a Microservices Architecture over a monolithic architecture?
- Easier code maintenance
- Faster execution of a single codebase
- Improved scalability and flexibility
- Reduced network overhead
Microservices Architecture offers improved scalability and flexibility by breaking down applications into smaller, independent services.
