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.
_______ 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.
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.
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.
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.
_________ is a cryptographic protocol used to secure web communications.
- FTP
- HTTPS
- SNMP
- SSH
HTTPS (Hypertext Transfer Protocol Secure) is a cryptographic protocol used to secure web communications, providing a secure version of HTTP.
SOAP uses _______ for message format, while REST typically uses formats like _______.
- HTML
- JSON
- XML
- YAML
SOAP (Simple Object Access Protocol) uses XML (eXtensible Markup Language) for message format, whereas REST (Representational State Transfer) typically uses formats like JSON (JavaScript Object Notation) for data interchange due to its simplicity and ease of use in web applications.
In TLS 1.3, what major security improvement was made compared to its predecessors?
- Elimination of vulnerable cryptographic algorithms and negotiation procedures
- Increased reliance on outdated ciphers for backward compatibility
- Introduction of a complex key exchange mechanism
- Reduction of encryption strength for better performance
TLS 1.3 made a major security improvement by eliminating vulnerable cryptographic algorithms and negotiation procedures, enhancing overall security.
Which of the following is not a characteristic of SOAP-based web services?
- Lightweight
- Loose coupling
- Platform-independent
- Stateless
SOAP-based web services are not typically considered lightweight; they involve more overhead due to the XML format and additional protocols.
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.
