What is the recommended approach when an unexpected failure occurs during a performance test?

Immediately stop the test and restart from scratch without documentation

Change the load profile without recording the change

Apply the predefined procedure for handling such issues

Ignore the failure and continue the test as if nothing happened

Why is continuous monitoring important during performance test execution?

To automatically fix any performance issues found

To detect anomalies early and ensure the required data is collected

To eliminate the need for post-test analysis

To reduce the total test execution time

A performance test team is configuring a load testing tool for a test that simulates 500 concurrent users. The test design specifies a ramp-up period of 10 minutes and a steady-state duration of 20 minutes. The team sets the tool to start 50 users every minute for 10 minutes, then hold for 20 minutes. During a trial run, they notice that the tool is not applying the ramp-up correctly; it starts all 500 users immediately. What is the most likely cause?

The test data is not properly parameterized.

The load profile settings are not configured correctly in the tool.

The network bandwidth is insufficient for the load test.

The monitoring settings are interfering with the load generation.

What is the primary purpose of monitoring the execution of a performance test scenario?

To ensure the test proceeds as intended and the load profile is applied correctly

To configure the load generators

To prepare the test data for the next scenario

During a performance test, the application server crashes. The test engineer is following the predefined procedure for system crashes. The procedure says to stop the test, collect the logs, and notify the infrastructure team. What should the engineer do first?

Collect the logs before stopping the test.

Restart the application server and continue the test.

Notify the infrastructure team before stopping the test.
