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.
In performance testing, what does the term 'latency' refer to?
- The amount of data that can be processed simultaneously
- The delay between sending a request and receiving the response
- The number of concurrent users
- The speed of data transmission
Latency in performance testing refers to the delay between sending a request and receiving the corresponding response, measuring the time taken for data to travel between points.
How does unit testing contribute to the continuous integration process of web services?
- By increasing the likelihood of bugs in production
- By providing rapid feedback on code changes
- By skipping the testing phase
- By slowing down the integration process
Unit testing contributes to continuous integration by providing rapid feedback on code changes, helping catch issues early in the development process.
In SOA, _______ is a common approach for integrating heterogeneous systems.
- Enterprise Service Bus (ESB)
- Representational State Transfer (REST)
- Service-Oriented Architecture
- Web Service Description Language (WSDL)
In Service-Oriented Architecture (SOA), the Enterprise Service Bus (ESB) is a common approach for integrating heterogeneous systems. The ESB facilitates communication and integration between different services and applications in a loosely coupled manner.
Which HTTP method is commonly used for creating resources in REST?
- DELETE
- GET
- POST
- PUT
The HTTP method commonly used for creating resources in REST is POST. It is used to submit data to be processed to a specified resource.
In WSDL, the term 'binding' refers to what?
- The association between the abstract interface and a concrete protocol
- The definition of complex data types
- The process of connecting to a database
- The specification of user interfaces
In WSDL, 'binding' refers to the association between the abstract interface and a concrete protocol. It defines how the web service will be accessed over the network.
What is the role of a namespace in XML-based web service versioning?
- Avoid naming conflicts in different versions
- Enhance security in web service communication
- Provide a unique identifier to each version
- Simplify XML document structure
A namespace in XML-based web service versioning plays a crucial role in avoiding naming conflicts between different versions, ensuring clarity and preventing ambiguity.
When designing a web service for a healthcare application, what encryption standards must be considered for compliance?
- FERPA
- GDPR
- HIPAA
- PCI DSS
Healthcare applications must consider compliance with the Health Insurance Portability and Accountability Act (HIPAA) for encryption standards.
What is the main advantage of using elliptic curve cryptography over RSA in web services?
- Faster decryption speed
- Greater compatibility with legacy systems
- Improved resistance to quantum attacks
- Smaller key sizes with equivalent security
Elliptic curve cryptography offers the advantage of providing equivalent security with smaller key sizes, making it more efficient for resource-constrained environments like web services.
