CT-MAT sample questions

Question 1

You are defining the device selection strategy for a new e-commerce application targeting the European market. The marketing team has provided analytics data indicating the following user distribution: 45% Android (mostly versions 12-14), 50% iOS (mostly latest 2 versions), and 5% legacy/other. The budget allows for a limited number of physical test devices. Based on the ISTQB Mobile Application Testing syllabus, which approach represents the MOST effective risk-based device selection strategy?

Accepted Answer

Analyze the specific manufacturer and screen resolution data from the provided analytics, prioritize the top devices covering 80% of the active user base, and use cloud-based testing for the 'long tail' of legacy devices.

Answer

Select the top 10 most popular devices globally to ensure the widest theoretical coverage, ignoring the specific European data.

Answer

Focus exclusively on the latest flagship devices from Apple and Samsung since they represent the highest revenue potential per user.

Answer

Allocate 50% of the devices to Android and 50% to iOS, selecting the oldest supported versions to ensure backward compatibility is prioritized over current market usage.

Question 2

A startup is launching a 'Freemium' mobile game where the core loop is free, but users can purchase cosmetic items or watch ads to speed up progress. Which specific test scenario is CRITICAL for this business model to prevent revenue loss and ensure user retention?

Accepted Answer

Ensuring that purchasing a cosmetic item correctly unlocks the content and that ad rewards are granted only after the ad creates a 'completed' callback.

Answer

Verifying that the application installation process completes within 30 seconds on high-end devices.

Answer

Testing the application's performance when the device battery is below 15%.

Answer

Checking if the application can be uninstalled without leaving residual files.

Question 3

You are testing a mobile banking application that uses a Hybrid architecture. The app consists of a native container wrapping a Single Page Application (SPA). When testing the 'Offline Mode' capability, what is the primary technical limitation you should expect compared to a fully Native application?

Accepted Answer

The hybrid app may rely heavily on web view caching and might have slower performance or limited access to background sync services compared to native code.

Answer

The hybrid app cannot access the device's local storage or SQLite database, making offline data persistence impossible.

Answer

Hybrid applications are strictly prohibited from functioning without an active internet connection by Apple and Google store guidelines.

Answer

The native container automatically handles all offline syncing without any development effort, unlike native apps.

Question 4

Which of the following metrics are ESSENTIAL when calculating the 'Market Coverage' for a proposed list of test devices? (Select TWO)

Accepted Answer

The percentage of the target audience using the specific Operating System version (e.g., iOS 17.x).

Accepted Answer

The resolution and pixel density (DPI) popularity within the target region.

Answer

The release date of the physical device hardware.

Answer

The resale value of the device in the secondary market.

Question 5

A medical device company is developing a companion app that reads data from a bluetooth-connected insulin pump. Due to the critical nature of the app (safety-critical), which risk mitigation strategy is MOST appropriate during the test planning phase?

Accepted Answer

Adopt a rigorous extensive testing approach including physical device testing with actual pumps, focusing on connectivity loss, data corruption, and regulatory compliance (e.g., FDA/MDR) over cosmetic UI issues.

Answer

Rely primarily on emulators to ensure consistent, repeatable test environments free from hardware interference.

Answer

Use crowdsourced testing to get the maximum number of users testing the pump connection in real-world scenarios.

Answer

Limit testing to the 'Happy Path' to ensure the device works correctly under normal conditions, as edge cases are rare.

Question 6

True or False: A 'Thin Client' mobile application architecture performs the majority of business logic processing on the mobile device itself to reduce server load.

Accepted Answer

False

Answer

True

Question 7

You are preparing a test plan for a Progressive Web App (PWA). Which of the following test scenarios is UNIQUE to PWAs compared to standard responsive websites?

Accepted Answer

Verifying the 'Add to Home Screen' prompt appears and the Service Worker correctly caches assets for offline use.

Answer

Verifying the correct rendering of CSS media queries on different screen sizes.

Answer

Verifying that hyperlinks navigate to the correct destination pages.

Answer

Verifying the application works on Chrome and Safari browsers.

Question 8

When conducting 'Interruption Testing' on a mobile banking application, you simulate an incoming phone call while a user is in the middle of a transaction transfer. What is the expected 'correct' behavior you are validating?

Accepted Answer

The application should go to the background, pause execution, and upon resumption, present the user with the same state (or a lock screen if timeout occurred) without data loss.

Answer

The application should crash immediately to protect user data.

Answer

The application should automatically complete the transaction in the background to save the user time.

Answer

The application should block the incoming call to ensure the transaction finishes.

Question 9

You are testing the 'Runtime Permission' model on an Android 14 device. The user has previously selected 'Don't allow' for the Camera permission. When the user attempts to access the camera feature in the app again, what is the best practice behavior the app should demonstrate?

Accepted Answer

The app should display a rationale dialog explaining why the feature is needed and provide a link to the OS Settings page to manually enable the permission.

Answer

The app should force close since it cannot function without the camera.

Answer

The app should silently fail and do nothing when the button is tapped.

Answer

The app should bypass the system dialog and turn on the camera using root privileges.

Question 10

Which of the following scenarios represents a 'False Negative' in mobile automated testing?

Accepted Answer

The test script passes successfully, but the application actually crashed in the background during execution.

Answer

The test script fails because the element ID changed in the new build, but the feature works fine manually.

Answer

The test script fails, and the application has a critical bug.

Answer

The test script passes, and the application functions correctly.
