How does XML differ from JSON in terms of data structure representation?
- Graph-based structure
- Hierarchical structure
- Sequential structure
- Tree structure
XML represents data in a hierarchical structure, allowing nested elements and complex relationships. In contrast, JSON uses a tree structure, making it more straightforward with a sequential and easily readable format. Understanding these differences is crucial when choosing the appropriate format for data representation.
For a web service handling health information, which compliance standard takes precedence in the U.S.?
- FERPA (Family Educational Rights and Privacy Act)
- GDPR (General Data Protection Regulation)
- HIPAA (Health Insurance Portability and Accountability Act)
- PCI DSS (Payment Card Industry Data Security Standard)
In the U.S., web services handling health information must comply with HIPAA, which ensures the security and privacy of healthcare data.
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.
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 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 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 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.
