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.
_______ is used in REST to request the server to accept the entity enclosed in the request as a new subordinate of the web resource.
- DELETE
- PATCH
- POST
- PUT
In REST, the POST method is used to request the server to accept the entity enclosed in the request as a new subordinate of the web resource. It is often used for creating a new resource or submitting data to be processed, and the server responds with the details of the newly created resource.
_______ is a protocol used in SAML to pass the authentication and authorization decisions.
- Secure Authentication Protocol
- Secure Authorization Markup Language
- Security Assertion Markup Language
- Simple Authentication and Authorization Protocol
SAML uses the Security Assertion Markup Language protocol to pass authentication and authorization decisions.
How does an API Gateway assist in implementing authentication and authorization for APIs?
- It centralizes authentication and authorization logic, acting as a security guard for APIs
- It encrypts the data exchanged between APIs
- It only authenticates users and does not handle authorization
- It provides a platform for developing APIs but does not handle authentication and authorization
An API Gateway assists by centralizing authentication and authorization logic, serving as a security layer for APIs, ensuring secure access and controlled permissions.
