In Docker, what is a 'Dockerfile' used for?
- Configuring container security policies
- Defining the structure and content of a container
- Managing Docker network configurations
- Storing container logs
A Dockerfile is used to define the structure and content of a Docker container, specifying the steps to build the container image.
In terms of API versioning, how does GraphQL differ from REST?
- GraphQL typically doesn't require versioning
- GraphQL uses URL versioning
- REST automatically handles version updates
- REST uses HTTP headers for versioning
GraphQL typically doesn't require versioning due to its flexible schema and ability to request only the needed data.
How does WSDL facilitate the interaction between different web services?
- By enabling user interface creation
- By executing server-side scripts
- By managing database connections
- By providing a standard way to describe the interface and communication protocols
WSDL (Web Services Description Language) facilitates interaction by providing a standardized way to describe the interface and communication protocols of web services. This allows for interoperability between different systems.
In debugging complex scenarios, _______ allows simulation of various service responses.
- Authorization
- Compression
- Encryption
- Mocking
Mocking allows developers to simulate various service responses, aiding in debugging complex scenarios.
In SOAP, _______ is used to encode complex data types.
- JSON
- SOAP Encoding
- WSDL
- XML Schema
SOAP Encoding is a method used in SOAP to encode complex data types in a way that can be transmitted over the network, facilitating interoperability.
The approach where tests are written before the actual web service code is known as _______.
- Agile Development
- Behavior-Driven Development (BDD)
- Test-Driven Development (TDD)
- Waterfall Development
Test-Driven Development (TDD) is an approach where tests are written before writing the actual code, promoting a more testable and reliable codebase.
What metric in performance testing measures the number of requests a service can handle per second?
- Concurrent Users
- Latency
- Response Time
- Throughput
Throughput in performance testing measures the number of requests a service can handle per second, providing insight into system capacity.
What is the primary difference between HTTP and HTTPS protocols in web services?
- Data Encryption
- Header Formats
- Port Numbers
- Request Methods
The primary difference between HTTP and HTTPS is that HTTPS encrypts data during transmission. It uses protocols like SSL/TLS to secure the communication channel, providing a secure and private connection between the client and the server.
For automated testing, Postman integrates with _______ for continuous delivery.
- Docker
- GitLab
- JIRA
- Jenkins
Postman integrates with Jenkins for continuous delivery in automated testing processes.
For microservices, _______ testing is crucial to ensure each service functions correctly within the larger system.
- Component
- End-to-End
- Regression
- Unit
End-to-End testing for microservices is crucial to ensure that each service functions correctly within the larger system.
