49. What conclusion can you draw for File Data Operations? (1 point)

 

  Processor queue and file data operations correlate and show that the system is backlogged.

  Rising CPU and file data operations indicate the system is backlogged.

  Processor queue and file data operations are in contrast and the system is not backlogged.

  Rising CPU and file data operations correlate to show the system is well tuned for I/O operations.

47. What do the readings for processor queue length indicate? (1 point)

 

  Processor queue length is average; the system is processing on acceptable levels.

  Processor queue length is below normal and indicates too little hardware is utilized by the system.

  Hits per Second

  Throughput

  Windows Resources

  Apache

 

39. What setting will you use so that all Vusers are initialized before starting the scenario? (1 point)

 

  Reset

  Run/Stop Vusers

  Initialize Vusers before run

  Load all Vusers simultaneously

 

38. An application has an actual peak load value of 150 users. If you are creating an Overload scenario that comprises 120% of the actual peak load value, how many Vusers will you run? (3 points)         

 

37. Which feature allows you to configure the ramp up, ramp down, and duration options during a load test? (1 point)

 

  Schedule builder

  Design tab

  Edit Schedule

  Run tab

 

36. What setting will you configure to add the machines whose resources you want to monitor?

 

  Under Tools > Options

  UnderAdd Measurements…

  UnderFreeze

  UnderConfigure…

 

35. Thinktimes are included in the Vuser scrīpt you are debugging. Since this is not yet a load test, you want to reduce the thinktime values to only a portion of the original recorded values. Which thinktime settings can you use to meet this requirement? Choose TWO. (2 points)

 

  As recorded

  Multiply thinktime by

  Use random percentage of recorded thinktime

  Limit thinktime to x number of seconds (where x is 1)

 

 

34. Dynamic data that you may need to correlate can best be investigated using which logging feature? (1 point)

 

  Send messages only when an error occurs

  Standard log

  Parameter substitution

  Data returned by the server

  Advanced trace

 

33. One of the requirements for a Vuser scrīpt is to include dynamic values in the execution log. What LoadRunner feature will you use to include dynamic values in the execution log without modifying the scrīpt? (1 point)

 

  lr_output_message

  Extended log

  Web_reg_find

  Advanced log

 

32. Match the scenario type with the action being described. (4 points) 选ABCD

 

 This scenario run shows the responsiveness of a site under low stress and helps you validate business process functions for concurrent usage with data being used in the test. ()

This scenario applies the entire load through slow ramp up. The scenario is repeated until any bottlenecks found are investigated and corrected for optimum system performance. ()

This scenario allows you to see the final limits of the system and helps determine a safety factor for your system.()

ABCD This scenario is run to help you isolate the slowest transactions and helps you identify any system bottlenecks on major problem areas. ()

 A. Debug

B. TopTime

C. Full Load

D. Scalability

 

30. What setting would you configure to view the execution log that includes parameter substitution, data returned by the server, and advanced trace? (1 point)

 

  Send messages only on error

  Advanced automatic log

  Standard log

  Extended log

 

29. To control the time between iterations in a Vuser, you will need to configure which run-time feature? 

 

  Run Logic

  Pacing

  Think Time

  Network Speed

 

28. Which TWO statements represent best practice when selecting monitor measurements during an initial load test? (2 points)

 

  Add specific monitors to allow backend experts to confirm their diagnosis of the system under test.

  Add default monitors to get a broad spectrum of how the system is behaving under load.

  Add specific monitors to help you target suspected problems in specific servers or components.

  Add default monitors to help you isolate potential bottlenecks during the load test.
