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.
For a business aiming to provide dynamic binding of web services, what aspect of UDDI is most crucial?
- Publish API
- Quality of Service (QoS)
- Security and Authentication
- Subscription and Notification Mechanism
The Subscription and Notification Mechanism of UDDI is crucial for businesses aiming to provide dynamic binding of web services. This feature allows service consumers to subscribe to changes in service information, enabling dynamic updates and binding based on the evolving nature of services in the distributed environment. It facilitates agility and adaptability in integrating web services dynamically.
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.
