How can you create a custom query method in a Spring Data JPA repository?
- By defining a method with a specific naming convention.
- By using a native SQL query.
- By annotating a method with @Query and providing the JPQL query.
- By creating a new repository interface for custom queries.
In Spring Data JPA, you can create custom query methods by defining a method in your repository interface with a specific naming convention. Spring Data JPA generates the query based on the method name, eliminating the need to write explicit queries. The other options represent alternative ways to create custom queries but are not the typical approach in Spring Data JPA.
For web services communication, SOAP relies on _______ for message format validation.
- JSON
- REST
- WSDL
- XML Schema
SOAP uses XML Schema for message format validation, ensuring that the structure and content of messages conform to a predefined schema.
_______ in WSDL is used for defining abstract messages and their data structures.
In WSDL, the element is used for defining abstract messages and their data structures. It describes the data elements involved in a web service operation.
What is the primary language used for writing SOAP messages?
- CSS
- HTML
- JSON
- XML
The primary language used for writing SOAP messages is XML (eXtensible Markup Language). SOAP messages are encoded in XML format, providing a standardized way for communication between web services.
A web service needs to update its security protocols. Considering current best practices, which TLS version should it upgrade to?
- SSL 2.0
- SSL 3.0
- TLS 1.0
- TLS 1.3
Current best practices recommend upgrading to TLS 1.3 for improved security and cryptographic algorithms.
An effective way to mitigate XSS is to implement _______ encoding for user inputs.
- Base64
- HTML
- JavaScript
- URL
Implementing HTML encoding for user inputs is an effective way to mitigate Cross-Site Scripting (XSS) attacks.
What is a primary advantage of using cloud-based web services?
- Graphic design capabilities
- Offline functionality
- Scalability
- Spreadsheet calculations
Cloud-based web services offer scalability, allowing applications to handle varying workloads efficiently.
For a service that provides access to third-party applications, what authorization mechanism would ensure secure and limited access?
- API Key Authorization
- OAuth 2.0
- Role-Based Access Control (RBAC)
- SAML (Security Assertion Markup Language)
OAuth 2.0 is commonly used for authorization in scenarios where secure and limited access is required, especially for third-party applications.
How does AWS Lambda fundamentally change the way computing resources are used?
- Free tier with limited usage
- Hourly billing model
- Monthly subscription model
- Pay-per-execution model
AWS Lambda introduces a pay-per-execution model, allowing users to pay only for the compute time consumed by their functions.
_______ is a technique used to simulate real user interactions with a web service during testing.
- Automation Testing
- Load Testing
- Regression Testing
- Stress Testing
Automation testing involves using tools to simulate real user interactions, ensuring efficient testing of web services.
API Gateways often use _______ to ensure that requests are only served to authenticated and authorized users.
- API keys
- JSON
- OAuth
- Tokens
API Gateways often use OAuth to ensure that requests are only served to authenticated and authorized users.
What is the primary purpose of Web Services Interoperability?
- Designing user interfaces
- Ensuring security
- Facilitating communication between
- Managing databases
Web Services Interoperability aims to facilitate communication between different applications and systems. It ensures seamless integration by enabling diverse software to work together effectively, irrespective of their underlying technologies and platforms.
