For microservices, what strategy should be adopted for effective unit testing?
- Avoiding unit testing altogether
- Ignoring unit tests for microservices
- Mocking external dependencies
- Relying solely on end-to-end testing
Effective unit testing in microservices often involves mocking external dependencies to isolate each microservice during testing.
In UDDI, service providers are categorized under the _______ element.
- businessEntity
- providerCategory
- serviceClassification
- technicalDetails
In UDDI, service providers are categorized under the businessEntity element. This element is used to represent business entities, including service providers, and contains information about their services and other related details.
_______ 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.
SOAP services primarily communicate over which protocol?
- FTP
- HTTP
- SMTP
- TCP
SOAP services primarily communicate over the HTTP (Hypertext Transfer Protocol). Although SOAP itself is a protocol, it typically relies on HTTP as the transport protocol for sending and receiving messages between clients and services.
How does OAuth differ from traditional password-based authentication methods?
- OAuth and traditional methods are the same
- OAuth enables delegated access with tokens
- OAuth requires user credentials
- OAuth uses plaintext passwords for authentication
OAuth differs from traditional password-based methods by enabling delegated access through tokens. Instead of sharing sensitive credentials, OAuth issues tokens that grant limited and specific access, enhancing security and reducing the risk associated with password sharing.
