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.
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.
How does SOA contribute to business agility and process optimization?
- By enabling modular and reusable services
- By enforcing rigid business processes
- By limiting flexibility in system design
- By prioritizing technology over business needs
SOA contributes to business agility and process optimization by enabling the development of modular and reusable services. This allows organizations to adapt quickly to changing business requirements, streamline processes, and achieve greater flexibility in designing and implementing solutions.
For secure API access, _______ is a protocol for delegating authorization.
- LDAP
- OAuth
- SAML
- SSL
OAuth is a protocol commonly used for delegating authorization in the context of secure API access.
In a scenario where an organization needs to expose different APIs to various external clients, what feature of API Gateways is most beneficial?
- API Versioning
- Authentication and Authorization
- Rate Limiting
- Request Logging
API Versioning in API Gateways is most beneficial when an organization needs to expose different APIs to various external clients, allowing for smooth evolution and backward compatibility.
AWS _______ is a managed service that simplifies the setup and scaling of a distributed database system.
- ECS (Elastic Container Service)
- Lambda
- RDS (Relational Database Service)
- S3 (Simple Storage Service)
AWS RDS (Relational Database Service) is a managed service for databases, simplifying the setup and scaling of distributed database systems.
In a Microservices Architecture, services communicate with each other using _______.
- HTTP/HTTPS
- Message Queues
- REST
- SOAP
Services in a Microservices Architecture communicate with each other using Message Queues, enabling asynchronous and decoupled interactions.
In SOAP, the _______ defines the data types used in the message.
- UDDI
- WSDL
- XML Schema
- XML-RPC
In SOAP, the XML Schema is used to define the data types that can be used in the SOAP message, ensuring consistency in data representation.
