1. 1

   Which JMeter component defines the number of virtual users, loop count, and ramp-up period?

   

   A Thread Group B Response Assertion C View Results Tree
2. 2

   Which JMeter element sends an HTTP request to the application being tested?

   A Listener B HTTP Request sampler C CSV Data Set Config
3. 3

   What should be added to model the pause a real user makes between two actions?

   A A Listener B A Post-Processor C A Timer
4. 4

   A Thread Group starts 120 users over a 60-second ramp-up period. What is the average user start rate?

   

   A 2 users per second B 60 users per second C 120 users per second
5. 5

   What does a 95th-percentile response time of 1.8 seconds mean?

   A Exactly 95% of requests took 1.8 seconds B 95% of requests completed in 1.8 seconds or less C The slowest 5% averaged 1.8 seconds
6. 6

   The graph shows throughput flattening while response time rises sharply as more users are added. What does this most strongly indicate?

   

   A The application is scaling linearly B The requests contain no assertions C The system has reached a saturation point
7. 7

   In JMeter terminology, what does the latency metric generally measure?

   A Time from sending the request until the first response data is received B Time required to download only embedded resources C Delay inserted by timers before the request
8. 8

   A server returns a new anti-forgery token after login, and the next request must submit it. Which approach should the test use?

   

   A Hard-code one captured token for every virtual user B Extract the token from the response and reuse it through a variable C Increase the Thread Group ramp-up period
9. 9

   Which JMeter element is commonly used to provide different usernames and passwords to virtual users from a file?

   

   A Constant Timer B HTML Assertion C CSV Data Set Config
10. 10

    What is the main purpose of a Response Assertion in a JMeter test?

    A To verify that a response meets defined conditions B To control how quickly virtual users start C To distribute load across worker machines
11. 11

    Why should resource-intensive listeners such as View Results Tree usually be disabled during a large load test?

    A They prevent HTTP cookies from being stored B They can consume substantial memory and CPU on the load generator C They automatically reduce the number of server responses
12. 12

    Which command correctly runs a JMeter test plan in non-GUI mode and saves sample results?

    A jmeter -open test.jmx -view results.jtl B jmeter -gui false -save test.jmx C jmeter -n -t test.jmx -l results.jtl
13. 13

    In JMeter distributed testing, what is the controller primarily responsible for?

    

    A Coordinating remote workers and collecting their results B Replacing the application server under test C Generating all load without using worker machines
14. 14

    A stable system completes 40 requests per second, and average response time is 0.5 seconds. Using Little's Law, approximately how many requests are in progress on average?

    A 10 requests B 20 requests C 80 requests
15. 15

    Which JMeter component can be used to make a Thread Group approximate a specified request throughput?

    A Boundary Extractor B HTTP Cache Manager C Constant Throughput Timer
16. 16

    Which description best defines a stress test?

    

    A Increasing load beyond expected capacity to find limits and observe recovery B Testing one request with three different data values C Maintaining only normal production load for a short period
17. 17

    The workload chart rises abruptly from 100 to 2,000 active users, remains there briefly, and then drops abruptly. Which test pattern does it represent?

    

    A Soak test B Spike test C Baseline test
18. 18

    A realistic user journey includes reading a product page for several seconds before clicking Buy. How should this pause be modeled?

    A By increasing the HTTP connection timeout B By adding another Response Assertion C By placing an appropriate Timer before the next request
19. 19

    A test dashboard shows 2,000 total samples and 50 failed samples. What is the error percentage?

    

    A 2.5% B 4% C 25%
20. 20

    Why is a warm-up period often excluded from the main performance measurements?

    A It guarantees that all later requests will succeed B It allows caches, connection pools, and runtime optimization to stabilize C It removes the need to monitor server resources
