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.
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.
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.
_______ 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.
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.
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.
When developing a new mobile application that relies on fast and efficient data exchange, which data format is more suitable?
- BSON
- CSV
- JSON
- Protocol Buffers (protobuf)
For a mobile application requiring fast and efficient data exchange, Protocol Buffers (protobuf) is a more suitable choice. It offers a compact binary format, reducing the size of data payloads and improving serialization and deserialization speed. This is crucial for mobile applications operating in resource-constrained environments where bandwidth and processing power are significant factors in ensuring a responsive and seamless user experience.
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.
The _______ in a SOAP message specifies the actions to be performed.
- Body
- Envelope
- Fault
- Header
In a SOAP message, the Envelope element contains the Header and Body, and it specifies the actions to be performed.
_______ in JSON represents a significant advantage in terms of API response time compared to XML.
- Compact Syntax
- Data Binding
- Schema
- Verbosity
The compact syntax of JSON, with its minimalistic representation, contributes to a significant advantage in API response time compared to XML. JSON's lightweight format is more concise and results in faster data transmission, making it preferable for scenarios where response time is crucial.
Which protocol is commonly associated with RESTful web services?
- FTP
- HTTP
- SMTP
- TCP
RESTful web services are commonly associated with the HTTP protocol, which is used for communication between clients and servers over the web.
How does SOAP UI support WSDL validation?
- Automatically during runtime
- By importing the WSDL file
- By writing custom scripts
- Through integration with third-party tools
SOAP UI supports WSDL validation by allowing users to import the WSDL file associated with the web service being tested.
