The _______ algorithm in TLS is used for key agreement and establishment.
- AES
- HMAC
- RSA
- SHA-256
The RSA algorithm in TLS is utilized for key agreement and establishment during the handshake process.
A web service uses _______ for encrypting sensitive data in transit.
- FTPS
- HTTPS
- SNMP
- SSH
Web services commonly use HTTPS (Hypertext Transfer Protocol Secure) for encrypting sensitive data in transit.
What is a Web Service primarily used for in application development?
- Mobile app development
- Video game programming
- Web page design
- authentication and Authorization
Web Services primarily facilitate data exchange between different software applications. They allow interoperability between different systems.
A company is deploying a new set of microservices and needs centralized monitoring of API traffic. Which component is most crucial?
- API Gateway
- Database
- Load Balancer
- Message Queue
In microservices architecture, an API Gateway is crucial for centralized monitoring of API traffic, allowing for efficient management and analysis.
WSDL documents are often used in combination with _______ for describing web service functionalities.
- REST
- SOAP
- UDDI
- XML
WSDL documents are often used in combination with XML to describe web service functionalities. XML is used to define the structure of the data exchanged between the web service and its clients.
What is the primary purpose of SOAP in web services?
- Defining a standard communication protocol
- Designing user interfaces
- Enabling RESTful services
- Managing databases
SOAP (Simple Object Access Protocol) is primarily used to define a standard communication protocol for web services. It provides a way for programs running on different operating systems to communicate with each other.
In SOAP services, what does the envelope element define?
- Contains the entire message
- Defines the data format
- Encloses the header and body
- Specifies the protocol
In SOAP services, the envelope element defines the overall structure of the XML message. It encapsulates the header and body elements, providing a standardized structure for organizing information within a SOAP message. The envelope ensures consistency in message formatting and helps both the sender and receiver understand the structure of the data being exchanged.
When a web service shows different behaviors for different users, what debugging approach should be considered?
- Code refactoring
- Load testing
- Logging and tracing
- User-specific data issues
When a web service exhibits different behaviors for different users, logging and tracing can help identify the root cause by capturing detailed information about the execution flow.
The use of _______ in XML facilitates more rigorous data validation than JSON.
- DTD
- JSON Schema
- XML Schema
- XPath
XML Schema (XSD) is commonly used in XML to define the structure and constraints of the data. It enables more rigorous data validation compared to JSON, as JSON relies on a less formalized schema approach. XML Schema provides a way to enforce specific data types, constraints, and relationships within XML documents.
In a scenario where XML data needs to be transformed into different formats for various clients, what technology should be used?
- Extensible Stylesheet Language Transformations (XSLT)
- JavaScript Object Notation (JSON)
- Simple Object Access Protocol (SOAP)
- Web Services Description Language (WSDL)
Extensible Stylesheet Language Transformations (XSLT) is used for transforming XML data into different formats, making it suitable for various clients.
