CTAL-TAv4.0 Certification Exam Guide + Practice Questions Updated 2026

You plan to test a computer game on various configurations.
A configuration consists of: operating system (2 possible values:
Windows 10, Windows 11) browser (4 possible values: Edge, Chrome, Firefox, Opera)
RAM type (4 possible values: 8 GB, 16 GB, 32 GB, 64 GB)
Market research shows that 90% of gamers own the same configuration: Windows 11, Chrome, 32 GB.
You use combinatorial testing with the base choice coverage.
What is the MINIMUM number of configurations that need to be tested to achieve 100% base choice coverage?

The test analyst defined four test cases for the test condition: “Verify that the system refuses to log in if the login information is incorrect.”
Where in the test process did the test analyst perform this task?

You are a test analyst on a project producing a critical system―an air traffic management application to support controllers in monitoring, planning, and managing flights in real-time. The application's goal is to improve flight safety, airspace management, and route optimization, considering changing factors such as weather conditions, alternate routes, flight priorities, and dynamic schedule changes.
In a conversation with the system architect, you learn that the application has to handle many different combinations of variables, such as flight type, weather conditions, flight priority, or current airspace status. When you talk to air traffic controllers, you learn that the application performs complex operations that not only process data but also generate data based on already existing information. For example, when weather conditions change, the flight route is dynamically recalculated, and the system automatically modifies the route. This makes some data dependencies difficult to grasp and predict directly.
Based on this scenario, which TWO test techniques will be best suited for this project? (Choose two.)

As a test analyst, you have been asked to conduct a role-based review of the usability of the electronic banking system’s user interface. The interface allows the user to choose a language from English, Spanish, or Italian. The system is secured with a multi-factor authentication mechanism. After logging in, the user can manage their loans.
During the review, you take the role described by the following persona:
Name: Maria Rossi
Age: 64
Occupation: retired Italian language teacher
Knowledge of technology: basic; she is afraid of technology
Hardware: Windows laptop, Android phone
Place of residence: Rome, Italy
Language skills: Italian (native), Spanish (basic)
What could MOST likely be reported by you during this review?

A technology company called TechSoft has just completed the development phase of a new module in its Pro Task project management mobile application. The new module - “Notifications and alerts” - allows users to receive notifications about the status of their tasks and messages. The functionality includes configuring different types of notifications (email, SMS, push), notification frequency, and customizing notifications according to the user's role.
Due to the many possible combinations of settings and the various usage scenarios, the project team has decided to do exploratory testing, with a focus on verifying the functionality of notifications in an environment that replicates the end-user environment as closely as possible.
Tech Soft has software for designing tests that meet combinatorial coverage criteria, such as pairwise coverage. It also has the latest version of a test management tool.
As a test analyst, you have been asked to prepare a test charter for exploratory testing.
Which TWO pieces of information should be included in the charter? (Choose two.)
