What is the primary use of Postman in web services testing?
- Creating databases
- Generating random data
- Graphic design in web development
- Sending HTTP requests and testing APIs
Postman is primarily used for sending HTTP requests and testing APIs, allowing developers to interact with web services.
The _______ protocol is deprecated in favor of TLS for securing web services.
- FTP
- HTTP
- SMTP
- SSL
The SSL (Secure Sockets Layer) protocol is deprecated in favor of TLS (Transport Layer Security) for securing web services.
RESTful APIs use HTTP _______ to perform operations on resources.
- Actions
- Methods
- Requests
- Verbs
RESTful APIs use HTTP methods, also known as HTTP verbs, to perform operations on resources. Common methods include GET, POST, PUT, DELETE, etc.
The use of _______ ensures that web services can be accessed regardless of programming language or platform.
- CORBA (Common Object Request Broker Architecture)
- HTTP (Hypertext Transfer Protocol)
- URI (Uniform Resource Identifier)
- WSDL (Web Services Description Language)
The use of URI (Uniform Resource Identifier) ensures that web services can be accessed regardless of programming language or platform. URIs provide a standardized way to identify and locate resources on the web, promoting a language-agnostic and platform-independent approach.
How does JWT differ from session-based authentication in terms of scalability?
- JWTs and session-based authentication have similar scalability
- JWTs are stateless and don't require server-side storage
- JWTs require frequent server-side storage updates
- Session-based authentication is more scalable
JWTs (JSON Web Tokens) are stateless, meaning they don't require server-side storage, making them more scalable than session-based authentication, which relies on server-side storage.
A financial service is transmitting sensitive data over the web. Which encryption technique should be prioritized for data protection?
- AES
- Blowfish
- RSA
- Triple DES
In the context of transmitting sensitive data, Advanced Encryption Standard (AES) is commonly prioritized for its robust security.
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.
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.
