Which of the following is a fundamental component of Docker?
- Docker image
- HTML file
- Java compiler
- Video player
A Docker image is a fundamental component, serving as a lightweight, standalone, and executable software package that includes everything needed to run a piece of software.
To achieve seamless integration across different systems, the concept of _______ is applied in web services.
- API (Application Programming Interface)
- Encryption
- Middleware
- Service-Oriented Architecture (SOA)
To achieve seamless integration across different systems, the concept of Service-Oriented Architecture (SOA) is applied in web services. SOA is an architectural approach that enables the creation of modular and reusable services, promoting interoperability by allowing different applications to communicate and collaborate effectively.
What type of encryption is used by HTTPS to secure communication in web services?
- Asymmetric-Key Encryption
- Hashing Algorithms
- Public-Key Infrastructure (PKI)
- Symmetric-Key Encryption
HTTPS primarily uses Asymmetric-Key Encryption. It employs a combination of public and private keys to secure communication between the client and the server. This ensures confidentiality and integrity by encrypting data in transit, providing a secure environment for web services.
_______ is essential for maintaining the lifecycle of services in SOA.
- Service Choreography
- Service Composition
- Service Governance
- Service Orchestration
Service Governance is essential for maintaining the lifecycle of services in SOA. It involves defining and enforcing policies, standards, and guidelines to ensure that services are developed, deployed, and managed consistently throughout their lifecycle. This helps in achieving reliability, security, and overall effectiveness in service-oriented architectures.
In a scenario where a web service must support multiple clients with different needs, how does WSDL contribute?
- It allows defining multiple endpoints
- It enforces security policies
- It manages database connections
- It specifies the programming language for clients
WSDL allows defining multiple endpoints, enabling the web service to cater to various clients with different requirements by exposing different sets of operations.
When introducing a breaking change in a RESTful API, what versioning approach is most appropriate?
- Header Versioning
- Media Type Versioning
- Query Parameter Versioning
- URI Versioning
URI Versioning involves including the version information directly in the URI, which is suitable for handling breaking changes in a RESTful API.
How does SOAP handle data encoding for transmission?
- It does not handle data encoding
- It uses JSON for encoding data
- It uses XML for encoding data
- It uses binary encoding for efficiency
SOAP typically uses XML for encoding data. XML provides a standardized way to represent structured data, making it platform-independent and human-readable.
JSON is a subset of _______, making it highly compatible with web browsers.
- CSS
- HTML
- JavaScript
- XML
JSON is a subset of JavaScript, making it highly compatible with web browsers. JavaScript Object Notation (JSON) is a lightweight data interchange format derived from JavaScript, ensuring seamless integration with JavaScript-based applications.
UDDI's role in a _______ architecture is to facilitate service management and discovery.
- Cloud-Based
- Microservices
- Monolithic
- Service-Oriented
UDDI plays a crucial role in a Service-Oriented architecture by facilitating service management and discovery. In a Service-Oriented architecture, services are designed to be independent and loosely coupled, and UDDI helps manage and discover these services, promoting flexibility and interoperability in the architecture.
How does RESTful architecture optimize network communication?
- By encrypting all communication channels
- By increasing the payload size of each request
- By relying on complex session management
- By using stateless communication and caching mechanisms
RESTful architecture optimizes network communication by adopting a stateless approach, reducing the need for server-side storage of client state. Caching mechanisms further enhance performance.
Azure _______ is a cloud computing service for building, testing, deploying, and managing applications through Microsoft-managed data centers.
- App Service
- Cosmos DB
- Functions
- Logic Apps
Azure App Service is a cloud computing service that supports building, testing, deploying, and managing applications.
For a service experiencing intermittent errors, _______ testing is crucial for identifying the problem.
- Load
- Performance
- Regression
- Stress
Load testing is essential for identifying intermittent errors and bottlenecks in web services.
