• C. What are the targetfor CPU utilization and memory consumption for the web services platforms receiving question responses?
• D. What is the projected participation growth rate over the next nine months?

Answer: C

NEW QUESTION 5
You have been asked to test the performance of a software and system update to a North American mobile trivia quiz game application The quiz app is available on major app stores serving English-speaking users.The number of concurrent users planned for is 5 million Winning quiz participants are promised a share of an allocated cash prize Once participants start playing, their quiz sessions must not be lost especially if all previous questions were answered correctly. The application owner wants to ensure that 99% of quiz sessions are maintained (up to 4.95 million sessions) until the last answer has been successfully recorded.
You performed 100 test runs that provided 5 million virtual concurrent users.You have measurements of participant concurrency at the last question for each test run In your analysis, you order all the concurrency test results by measured concurrency value from best to worst.You determine 85%. 90%. 95% and 100% values by selecting the 85th. 90th. 95th and 100th (last and worst) measured values by counting list positions starting from the best value going towards the worst until you reach the desired list position (ex. 85). Keep in mind, the results in lower list positions are as good or better than the results chosen for reporting.
After analyzing the results of the performance tests, you present the following results 85% 4.92 million valid concurrent users
90% 4.90 million valid concurrent users
95%: 4.0 millionvalid concurrent users
100%. 3.8 million valid concurrent users
Based on these results, what should you report to thestakeholders?

• A. The performance tests clearly have failed to produce a realistic and compatible load.The results should confirm the test oracle in that the 99% of five million participants concurrency objective has been achieved.If the performance test plan had worked correctly, the reported values should have been 85% 4.95, 90% 4.95, 95% 4 95 and 100% 4.95 million valid concurrent users.
• B. These results clearly show that the system update successfully supports 99% of five million participants
• C. Four samples from the first fifteen ordered test results are presente
• D. The system update performed much worse than what is presented her
• E. The system update has failed to meet the 99% of five million participants concurrency objective.
• F. If we pick 85 out of 100 test runs as the minimum level of reliability, thesystem update does not reliabilitymeet the 99% of five million participants concurrency target,However not all results are as bad as these

Answer: A

NEW QUESTION 6
Which section of a performance test script is typically responsible for ensuring the script will have the right values and communication settings during execution?

• A. main section
• B. clean-up section
• C. initialization section
• D. timer section

You have been asked to test the performance of a software and system update to a North American mobile trivia quiz game application.

The application owner wants to ensure that 99% of quiz sessions are maintained (up to 4.95 million sessions) until the last answer has been successfully recorded
In order to avoid cooperation among quiz participants, the answers to the multiple choice questions are listed randomly Confidence in the game's fairness requires that a registered user originate from only one quiz client device Every user must respond over the same short window of time in order toavoid external assistance and learning the official answer before responding. Only participants who respond correctly may answer the next question Any activity that appears to violate expected behavior of a rule-following participant will cause the client session to be rejected.
You are developing test script code that handles quiz question responses. To do this you need to ensure that the script emulates the production quiz app client's logic in terms of rule following and client-backend interface specification.
Based on the question description provided, which is one test script behavior you would implement in order to ensure the test script successfully delivers the operational and load profile of a quiz participant?

• A. Recognize whether the previous question response was correct
• B. Set the device identifier as a constant to ensure all virtual user instances use the set valuecorrect
• C. Randomly select the maximum think time limit used to delay question responses.
• D. Use the date-time clock in order to submit question responses on a synchronized schedule with each instance

Answer: B

NEW QUESTION 8
What statement is TRUE regarding the security policies provided by Nuage VCS?

• A. The match criteria in security policies can be based on MAC address, IP address and TCP/UDP port number.
• B. Each policy entry has an associated priority that defines the order in which policy entries are evaluated.
• C. Ingress security policy controls the traffic flowing into the virtual machine.
• D. The default ingress security policy allows all traffic to be forwarded.

Answer: A

NEW QUESTION 9
How Is transaction elapsed time determined?

• A. response time - think time
• B. response time + think timecorrect
• C. response time + think time + nest time
• D. response time + think time - nest time

Answer: B

• B. stress test
• C. scalability test
• D. load test

Answer: B

NEW QUESTION 12
Which Is a valid reason for why performance testing load would be applied to the SUT in a ramp-up pattern during a performance test?

• A. Frequent sudden significant increases of toad allows the SUT performance to stabilize after each |ump in load thus exhibiting consistent behavior that results in measurements that are more reliable
• B. Gradually increasing the load ensures the SUT remains in a transient performance condition as it responds to the new increase in load thus exhibiting realistic behavior that improves the realism of the performance test
• C. Gradually increasing the load allows the SUT performance to stablize after each progressive increment of load thus exhibiting consistent behavior that results in measurements that are more reliable
• D. Frequent sudden significant increases of load ensures the SUT remains in a transient performance condition as it responds to each new large increase in load thus exhibiting consistent behavior that results in measurements that are more reliable.

Answer: B
