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.
When designing a secure API that requires user-specific data access, which security standard is most appropriate?
- JWT (JSON Web Tokens)
- OAuth 2.0
- OpenID Connect
- SAML (Security Assertion Markup Language)
OAuth 2.0 is a widely used security standard for securing APIs, especially when user-specific data access is needed. It provides a token-based authentication and authorization mechanism, allowing controlled access to resources without exposing user credentials.
In web service security, what does authorization determine?
- Encryption methods for data transmission
- IP addresses of connected clients
- Permissions and access control for authenticated users
- Quality of service metrics
Authorization in web service security determines the permissions and access control for authenticated users, specifying what actions they are allowed to perform.
What role does Kubernetes play in the management of containerized services?
- Database management for containerized services
- Graphic design for containerized services
- Load balancing for web servers
- Orchestration and scaling of containerized applications
Kubernetes is used for the orchestration and scaling of containerized applications, managing deployment, scaling, and operational tasks.
In a scenario where different development teams are working on separate modules of a web service, how should integration testing be approached?
- Conducting integration testing in a random order
- Conducting integration testing only after all modules are complete
- Incremental integration testing, starting with individual modules
- Skipping integration testing for individual modules
Incremental integration testing, starting with individual modules, helps identify issues early and ensures smoother integration of different modules.
What is the primary purpose of authentication in web services?
- Enhancing the visual appeal of web applications
- Monitoring network traffic
- Optimizing database queries
- Verifying the identity of users or systems accessing the service
Authentication in web services is primarily about verifying the identity of users or systems accessing the service, ensuring that only authorized entities can interact with it.
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.
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.
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.
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.
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.
_______ 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.
