Which tool is commonly used for creating mock RESTful services?
- Postman
- SoapUI
- Swagger
- WireMock
WireMock is commonly used for creating mock RESTful services, allowing developers to simulate responses for testing purposes.
Which design principle in SOA emphasizes the use of standardized service contracts?
- Service Abstraction
- Service Loose Coupling
- Service Reusability
- Service Standardization
In SOA, the design principle that emphasizes the use of standardized service contracts is Service Standardization. Standardized contracts define the way services interact, promoting consistency and interoperability. This principle facilitates a more uniform and predictable integration between services, contributing to the overall success of the SOA implementation.
What strategy can be used to handle deprecated features in web service versioning?
- Force clients to upgrade immediately
- Maintain backward compatibility
- Remove deprecated features abruptly
- Use version headers for each request
To handle deprecated features in web service versioning, maintaining backward compatibility is a common strategy. This allows existing clients to continue functioning while encouraging them to update gradually.
_______ is a tool in Docker for defining and running multi-container Docker applications.
- Docker Compose
- Docker Hub
- Docker Registry
- Docker Swarm
Docker Compose is a tool in Docker for defining and running multi-container Docker applications. It allows you to manage and orchestrate multiple containers as a single service.
How does a stress test differ from a load test in the context of web services?
- Load testing is not applicable to web services.
- Stress testing assesses system behavior under expected conditions, while load testing simulates extreme conditions to identify failure points.
- Stress testing focuses on normal usage conditions, while load testing simulates extreme conditions to identify failure points.
- Stress testing simulates extreme conditions beyond normal usage, focusing on system failure points. Load testing assesses system behavior under expected conditions, testing scalability.
Stress testing and load testing serve distinct purposes. Stress testing aims to evaluate system behavior under extreme conditions, while load testing assesses performance under expected conditions.
In REST, how are different resources typically accessed?
- Through HTML (Hypertext Markup Language)
- Through SOAP (Simple Object Access Protocol)
- Through TCP (Transmission Control Protocol)
- Through URIs (Uniform Resource Identifiers)
RESTful resources are typically accessed through URIs, providing a standardized way to identify and interact with resources.
_______ is a security vulnerability where an attacker can execute unauthorized commands.
- Cross-Site Request Forgery (CSRF)
- Cross-Site Scripting (XSS)
- Man-in-the-Middle (MitM)
- SQL Injection
SQL Injection is a security vulnerability where an attacker can execute unauthorized commands by injecting SQL code into input fields.
In REST, changing or adding fields requires a new _______ of the API.
- Endpoint
- Instance
- Method
- Version
In REST, modifying or adding fields typically necessitates the creation of a new version of the API.
A developer is tasked with enhancing the scalability of a web service. What design approach should be considered first?
- Distributed architecture
- Microservices architecture
- Monolithic architecture
- Serverless architecture
Microservices architecture is a design approach that promotes scalability by breaking down applications into smaller, independent services.
In HTTPS, data integrity is verified using ________.
- Certificates
- Digital Signatures
- Encryption
- Hash Functions
Data integrity in HTTPS is verified using hash functions. Hash functions generate fixed-size values (hashes) based on the content of the data. By comparing the received hash with the original hash, the recipient can ensure that the data has not been tampered with during transmission, maintaining the integrity of the information exchanged over the secure connection.
