What is the primary purpose of WS-Security in web services?
- Ensuring security in messages
- Handling web service errors
- Improving performance
- Managing session information
WS-Security is primarily used for ensuring security in messages exchanged between web services. It provides a set of specifications that enhance the integrity and confidentiality of the communication, addressing concerns related to authentication, encryption, and the prevention of message tampering.
Which scripting language is commonly exploited in Cross-Site Scripting (XSS) attacks?
- JavaScript
- PHP
- Python
- Ruby
Cross-Site Scripting (XSS) attacks commonly exploit vulnerabilities in JavaScript to inject malicious scripts into web pages.
What is the primary purpose of SSL/TLS in web services?
- Compress data for storage
- Encrypt data transmission
- Speed up data transfer
- Validate HTML code
SSL/TLS in web services is primarily used to encrypt data transmission, ensuring secure communication between clients and servers.
How does implementing idempotent operations in REST APIs enhance the service?
- Enhances security through encryption
- Ensures the same operation has the same effect, even if called multiple times
- Improves response time for non-idempotent operations
- Increases the complexity of the API
Idempotent operations in REST APIs ensure that the same operation has the same effect, even if called multiple times, which aids in reliability and consistency.
What is the role of a resource's representation in REST?
- It defines the resource's data schema
- It determines the resource's security settings
- It represents the current state of the resource and controls its interactions
- It specifies the location of the resource on the server
The representation of a resource in REST encapsulates its current state and governs interactions. This representation can be in various formats like JSON or XML.
Which tool is commonly used for load testing of web services?
- Apache JMeter
- Docker
- Git
- Selenium
Apache JMeter is a popular tool used for load testing of web services, allowing testers to simulate various user loads and analyze system performance.
Which service in AWS provides scalable computing capacity?
- AWS EC2 (Elastic Compute Cloud)
- AWS Lambda
- AWS RDS (Relational Database Service)
- AWS S3 (Simple Storage Service)
AWS EC2 (Elastic Compute Cloud) provides scalable computing capacity by allowing users to run virtual servers in the cloud.
For a service requiring detailed and structured contracts, _______ would be a more appropriate choice over _______.
- GraphQL
- REST
- SOAP
- WebSocket
For a service requiring detailed and structured contracts, SOAP (Simple Object Access Protocol) would be a more appropriate choice over REST (Representational State Transfer). SOAP provides a formal contract through WSDL (Web Services Description Language), making it suitable for scenarios where a strict and defined interface is crucial. REST, on the other hand, is more flexible and often preferred for lightweight and loosely-coupled systems.
The _______ feature in Azure provides a serverless compute service.
- Azure App Service
- Azure Batch
- Azure Functions
- Azure Logic Apps
Azure Functions is a serverless compute service that allows you to run event-triggered code without explicitly provisioning or managing infrastructure.
SOAP services use _______ to define the structure of the request and response messages.
- HTML
- JSON
- XML
- YAML
In SOAP services, XML is used to define the structure of both the request and response messages. XML provides a standardized format for data exchange, making it suitable for describing the structure and content of messages in a consistent manner.
