ISTQB CTAL-TTA Exam : Certified Tester Advanced Level Technical Test Analyst

You are working on a project that is integrating code from multiple development groups. There have been numerous integration problems, particularly regarding reliability, error recovery and transactional integrity.
You are now responsible for planning the performance efficiency testing for this product. There Is a strong feeling among the development managers that some parts of the code are weaker than others and will tend to exhibit problems during the performance efficiency testing. To identify these problematic areas as soon as possible, which type of testing should you do?

• A. Scalability testing
• B. Stress testing
• C. Load testing
• D. Interoperability testing

Your Agile team is developing a web-based system that will allow users to browse and buy online from a store's shopping catalogue. Continuous Integration has been implemented and technically it is working well, running several times per day, but each run is taking almost as much time as the team is prepared to allow. It is clear that after a few more iterations, as the number of tests needed grows with the product, it will be taking too much time.
Which of the four options contains a pair of solutions that will BOTH help to solve this problem?
a.Only include unit and component integration tests in the automated Cl runs.
b.Schedule low priority tests to be the first ones executed in each run, in order to provide rapid build verification.
c.Reduce the extent to which the automated tests go through the user interface, using technical interfaces instead.
d.Reduce the number of Cl cycles run each day.
e.Select a subset of automated tests for the daytime Cl runs, and run as many of the other tests as possible in an overnight cycle.
SELECT ONE OPTION

• A. a and c
• B. b and d
• C. c and e
• D. d and e

Which TWO of the following statements about Maintainability testing are TRUE?
A) It should start as soon as the draft design documents are available for review
B) An application can be considered maintainable when static analysis and code review defects have been fixed
C) It tests the regression impact of software or environmental changes to an operational system
D) It can be performed during Operational Acceptance Testing by multiple departments
E) It can be performed during User Acceptance Testing to ensure business processes can be maintained

• A. b and c
• B. a and d
• C. a and b
• D. d and e

A project to develop a new system has performance efficiency listed as a critical requirement. Which of the following describes how and when the Technical Test Analyst should FIRST be involved in performance test activities for the new system?

• A. Implementing the performance tool's load test scripts, for execution in a production-like environment during system test
• B. Designing an operational profile that does not exceed hardware, software, and network bandwidth test environment budgets
• C. Assisting the developers in determining CPU utilization for critical components during component testing
• D. Participating in code reviews that focus on database and component interactions as well as error handling

Consider the simplified logic below for crediting money to a bank account.
Receive money and account number to be credited
IF account number is valid
IF customer account is active
Store current account balance as oldBalance
Credit money to account
IF oldBalance < zero
IF balance now >= zero
Set message "Overdraft cleared"
ELSE
Set message "A/c overdrawn"
ENDIF
ELSE
Set message = "You have more money"
ENDIF
IF account holder is VIP customer
Send message by email to customer
ENDIF
ELSE
Set message "A/c inactive"
Send message by email to supervisor
ENDIF
ELSE
Add 1 to count of invalid inputs
ENDIF
What percentage of decision testing coverage has been achieved by the following suite of test cases?
Test Case A - Account number valid, account is active, oldBalance = -100, balance now = +200, not a VIP customer Test Case B - Account number valid, account is active, oldBalance = -100, balance now = -50, is a VIP customer

• A. 40%
• B. 60%
• C. 70%
• D. 80%
