Which web service protocol is known for its lightweight nature and ease of use through HTTP?
- CORBA
- REST
- SOAP
- XML-RPC
REST is known for its lightweight nature and ease of use through HTTP. RESTful services use simple and standard HTTP methods for communication, making them widely adopted for building scalable and interoperable web applications.
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.
In REST, how are different versions of a resource typically handled?
- By embedding the version information in the resource representation
- By using query parameters to specify the version in each request
- Through URI versioning, where the version is included in the resource's URI
- Through request headers indicating the desired version
Different versions of a resource in REST are commonly handled through URI versioning, where the version is explicitly mentioned in the resource's URI. This approach helps in maintaining backward compatibility.
In cloud-based web services, _______ allows the management of infrastructure through code.
- Cloud Automation
- Cloud Orchestration
- Code Infrastructure Management
- Infrastructure as Code (IaC)
Infrastructure as Code (IaC) enables the management of cloud infrastructure through code, providing automation and consistency.
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.
