LoadRunner Skills Competition

Customer says they need 95th percentile response time value for all transactions. Your scenario has 10 vusers which you know will generate at least 90 observations for each transaction. Your colleague says you must change your scenario to ensure 95th percentile can be calculated by LoadRunner. You decide to:

For LoadRunner Agent to be running in process mode on a Windows machine, what must be true?

You have 10 observations for response times (all in seconds) - 1,2,3,4,5,6,7,8,9,10. The correct values for average and 90th percentile are:

Your test scenario has 200 vusers. Beyond 50 vusers, you notice that response times stayed the same but Total transactions per second and Throughput (bytes) went down. You decide to:

Your script has a LoadRunner parameter called ticket_amount. In order to print its value for debugging purpose the right code is:

A character array called username can be declared in C as follows:

Run-time settings in the Controller allow you to select either thread or process mode for running your test. You prefer:

Receive Request Timeout value should be:

Customer's website allows keyword search (e.g. "Orville Wright Airplane") of all patent documents dating back to the 1950s. You have parameterized the search terms. Due to large expected load the number of vusers required in the scenario is ~1000. The system is known to cache the search results. The preferred data selection should be set to:

Sequential data selection setting for a parameter should be used:

lr_param_sprintf can be used to create a new parameter from a string.

IP spoofing configuration on a Windows Load Generator:

To prevent making requests during replay to hosts in a web HTTP/HTTP script that are of no interest to you (say external sites outside of your organization), you can:

VTS can be used:

Your customer has strict Response Time SLAs. You ran a test but forgot to add SLAs in the scenario before running it. You can:

A test scenario has 50 vusers. Think time is set to vary randomly between 50% to 150% of the recorded value. Pacing is set to 10 seconds. The test script has 5 transactions. The 95% response time SLA is 5 seconds. The test results indicate the SLAs were met. Customer asks if the system can support 50 simultaneous users in production. You say:

The vuser_init and vuser_end actions:

A client site has a homepage with several images, CSS and JS resources needed to render the page and wants to evaluate the performance for first-time users. The Web/HTTP script, with default Run-Time Settings, has a web_custom_request step with mode=HTML.  Select the most efficient strategy to download all the resources in order to simulate a browser page load:

A system is known to have 100 concurrent users at peak load.  In a scenario designed to simulate this load you would need 100 Vusers.
