CTAL-TA_SYLL2019 Question #54: Real Exam Question with Answer & Explanation

You have been assigned to test an application that allows users to conduct banking online. You have been asked to verify the various installation environments for the product. According to the specification the product supports four browsers (Edge, Chrome, FireFox and Safari), three operating systems (Windows, Mac, Unix), and four languages (English, Spanish, French, German). As you are reviewing the specifications you realize that the actual operating system names and versions were not included, only the major category. From this, you conclude that if you pick one from each of these sets (for example, select Windows 10 for the Windows OS), that testing should be sufficient. You have researched the product and determined that there should be no interaction between these three characteristics that would affect the operation of the system. However, you do want to exercise representative set of these options while conducting the other functional testing for the product. If you decide to test pairs of combinations, how many combinations will you need to test?
