ISTQB Exam CT-PT Topic 3 Question 2 Discussion

Actual exam question for ISTQB's CT-PT exam
Question #: 2
Topic #: 3
[All CT-PT Questions]

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

Show Suggested Answer Hide Answer
Suggested Answer: B

A ramp-up period in a performance test gradually increases load over time, and a ramp-down period does the opposite. This prevents sudden surges in system load, making test results more realistic.

Option A (Ensuring transactions complete in a time window) is incorrect because ramp-up/down periods do not control transaction timing.

Option C (Providing a buffer for slow transactions) is incorrect because ramp-up/down is about load balancing, not transaction timing.

Option D (Keeping all virtual users active throughout the test) is incorrect because ramp-down periods reduce users gradually.

Haha, D is a good one. Might as well ask if the test can make me a coffee while it's at it. Definitely going with B.

That's also important, but I believe simulating realistic user load is the primary reason.

D seems like a trick question. Guaranteeing all users remain active throughout the test duration? That's just unrealistic.

I agree with Jeannine. Gradual ramp-up and ramp-down is crucial for a realistic performance test. Sudden spikes in load can skew the results.

But what about ensuring virtual users complete their transactions within a defined time window?

I think the key reason is to simulate a more realistic user load pattern and avoid sudden system stress.

Option B sounds like the most sensible choice. Ramping up and down the user load helps simulate real-world usage patterns and avoids shocking the system.

I agree, option B makes sense. It's important to gradually increase and decrease the user load.
