CTAL-TTA practice question 15 of 25

Which statement correctly describes service virtualization’’ SELECT ONE OPTION

Answer options

A: It is a shareable testing service that simulates the behavior, data and performance of a system or service to which the product or component under test would normally be connected Correct answer

B: It is a service which automatically deploys new versions of the software into the production environment at regular and short intervals

C: it is an integrated set of tools that will automatically compile, test and deliver into a virtual environment a new build of the product under test

D: it is a collection of mock objects such as stubs and drivers that will allow a product or component to run without some other product or component that it would normally need

Correct Answer:

A. It is a shareable testing service that simulates the behavior, data and performance of a system or service to which the product or component under test would normally be connected

Explanation

Service virtualization simulates the behavior of dependent services, which enables testing components without needing the actual services, thereby improving continuous integration and testing practices.

Why Incorrect

B describes deployment automation, which is different from virtualization. C focuses on build processes rather than simulating external dependencies. D refers to mock objects but lacks the broader context of simulating service behaviors integrated into testing.
