How does REST handle state between client and server?
- Cookies for maintaining state
- Persistent server-side storage
- Session-based communication
- Stateless communication
REST relies on stateless communication, meaning each request from a client to a server contains all the information needed to understand and fulfill the request. This enhances scalability and simplicity.
_______ is a protocol that can be used with SOAP for reliable message delivery.
- FTP
- HTTP
- SMTP
- WS-ReliableMessaging
WS-ReliableMessaging is a protocol used with SOAP to ensure reliable and guaranteed message delivery in web services communication.
In basic terms, what does decryption do?
- Converts encrypted data back to its original form
- Generates random encryption keys
- Increases data complexity
- Secures network connections
Decryption, in basic terms, reverses the process of encryption, converting encrypted data back to its original, readable form.
In a distributed system, API Gateways facilitate _______ between different microservices.
- Authentication
- Authorization
- Communication
- Service discovery
API Gateways play a crucial role in facilitating communication between different microservices in a distributed system, ensuring seamless interaction and coordination.
_______ is the process by which a SAML assertion is exchanged for a service provider token.
- Assertion Transfer
- SAML Transformation
- Security Handshake
- Token Exchange
The process by which a SAML assertion is exchanged for a service provider token is known as Token Exchange.
Which technology is primarily used for containerization in web services?
- Docker
- HTML
- Java
- Python
Docker is a popular technology used for containerization in web services, providing a lightweight and portable environment.
In the context of API Gateway, what is rate limiting used for?
- Controlling the number of requests a client can make in a given time period
- Determining the color scheme of the API documentation
- Encrypting API data
- Managing the size of API responses
Rate limiting in an API Gateway is used to control the number of requests a client can make within a specified time period, preventing abuse and ensuring fair usage.
When configuring a web service for maximum security, what is a key consideration in the implementation of SSL/TLS?
- Plain Text Transmission
- Public Key Infrastructure (PKI)
- Simple Authentication
- Strong Cipher Suites
Choosing strong cipher suites is crucial for maximum security in SSL/TLS implementation, ensuring robust encryption for data in transit.
The _______ protocol in SOAP ensures data integrity and security, a feature not inherently present in REST.
- API Key
- OAuth
- SSL/TLS
- WS-Security
The WS-Security (Web Services Security) protocol in SOAP ensures data integrity and security. This is a significant feature not inherently present in REST, where security mechanisms often depend on the underlying transport layer (e.g., SSL/TLS) or additional authentication mechanisms like OAuth or API keys.
In terms of web services, what is a major security risk associated with HTTP that is mitigated by HTTPS?
- Insufficient server resources
- Lack of encryption for data in transit
- Limited support for RESTful APIs
- Vulnerability to SQL injection attacks
A major security risk associated with HTTP is the lack of encryption for data in transit. HTTPS addresses this concern by encrypting the communication between clients and servers, ensuring that sensitive information is secure and protected from unauthorized access or interception by malicious entities.
