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.
48. To determine if the network had issues with increasing traffic (or number of Vusers) during the loadtest, what merging graphs will you use to make this determination? Choose Two. (2 points)
Running Vusers with Transaction Response Time
Running Vusers with Hits per Second
Running Vusers with Throughput
Running Vusers with Transaction Peformance Summary
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 above normal and indicates system congestion.
Processor queue length is below normal and indicates too little hardware is utilized by the system.
46. What was the average CPU utilization (in percentage)? (2 points)
Note: Your answer should be in whole integers only. Decimals are not allowed.
45. If you want to show the correlated values (for automatic correlations) only for the current step in your scrīpt, what feature will you use?
Scan scrīpt for correlations
Show Differences In
Show only differences that appear in scrīpt
Show Scan for correlations popup after replay
44. Which utility do you use to identify dynamic values in a recorded scrīpt by comparing two scrīpts of similar recorded steps and data for correlation?
Automatic correlation
Correlation by recording
Compare with Vuser…
Scan
43. Which of the following functions adds a checkpoint in your scrīpt? Choose TWO. (2 points)
web_reg_find ( );
web_reg_save_param ( );
web_reg_add_cookie ( );
win_get_text ( );
obj_get_text ( );
42. What is the correct syntax to initialize a variable in VuGen?
int var1,
int var1;
int var1=2;
int var1==2;
40. If the load test objectives were to evaluate transaction response times and monitor server resources, which types of monitors would best meet these objectives? Choose TWO. (2 points)
Running Vusers
Transaction Response Time
Total Trans/Sec
Hits per Second
Throughput
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
Under ‘Add Measurements…’
Under ‘Freeze’
Under ‘Configure…’
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. WhatLoadRunnerfeature 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.
27. Which Run-Time Setting ensures that when a scrīpt is played back, there is caching in the browser, and each iteration simulates a new user? (1 point)
Additional attributes
Browser emulation
Miscellaneous
Preferences
Advanced options
26. What setting do you use to meet the requirement that the recording option for the scrīpt type be set to “A scrīpt describing user actions.” (1 point)
URL-based scrīpt
URL advanced
HTML-based scrīpt
HTML advanced
25. You want a Vuser scrīpt to capture a screenshot in case an error occurs during playback. Which setting will you configure to capture these errors? (1 point)
Continue on error
