Topic #: 2

[All CT-PT Questions]

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

Show Suggested 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.

I agree, B is the best answer. Sudden spikes in traffic can be unrealistic and mask underlying performance issues.

I agree with Cherry. Including ramp-up and ramp-down periods helps in creating a more realistic test scenario.

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

B) is the obvious choice here. Ramping up and down the user load helps simulate real-world usage patterns and prevents the system from being suddenly overwhelmed.
