ISTQB CT-PT Quiz 1 Topic 2 Questions 1-5

Question: 1

You are managing a project that is testing a system that manages a newly redesigned jet engine for heavy aircraft. Given the fact that this engine is specifically engineered to reduce noise, it is important that the software maintains enough thrust for lift for a period of 5 minutes without exceeding 87.5dB. The software must achieve this independent of other internal systems such as fuel or navigation management.

Given the risk for the ability of the aircraft to meet the noise abatement regulations while still being able to fly, when is the optimum time in the software lifecycle to apply the performance testing?

APreferably during each phase in the lifecycle

BPreferably at the end of system testing

CPreferably during system integration testing

DPreferably at the end of unit testing

Show Answer

Question: 2

What is typically the result of oversaturation of system resources during performance testing?

AResponse time will gradually improve over a period of time.

BResponse time will be slow under significant load levels.

CError logging will decrease.

DThe size of the database will gradually decrease.

Question: 3

Which of the following is a key challenge when testing applications in a cloud environment?

ALimited ability to control test execution timing

BInability to generate significant load

CLack of user behavior simulation tools

DTest execution speed being too high

Show Answer

Question: 4

Which of the following is usually identified by a performance test?

AResource bottlenecks

BSuitability issues

CLearnability concerns

DFailure to meet accessibility requirements

Show Answer

Question: 5

Which of the following is a key reason to include ramp-up and ramp-down periods in a performance test?

ATo ensure virtual users complete their transactions within a defined time window

BTo simulate a more realistic user load pattern and avoid sudden system stress

CTo provide a buffer for slow-performing transactions to complete

DTo guarantee that all virtual users remain active throughout the test duration
