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.
_______ versioning involves maintaining multiple versions of the service at the same time.
- Concurrent
- Horizontal
- Parallel
- Vertical
Concurrent versioning involves maintaining multiple versions of the service at the same time.
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.
