質問 2:
(REFER TO BASE SCENARIO 2): When you refer to Base Scenario 2. you are referring to the description and only the description, without any modification.
Question specific constraints: (specific constraints are not part of the Base Scenario and are specific to this question).
Natalie has run a performance test cycle. The following metrics have been collected:
Total virtual users: 10,000.
* Status of the simulated users.
o Total number of users for whom all transactions have been completed: 89%.
* Transaction response time, o Check-in
* Response time < 1 second: 60%
* Response time < 2 seconds: 70%
* Response time < 3 seconds: 88%
* Response time < 5 seconds: 90%
* Response time < 10 seconds: 95%
Question
Given this information, how should Natalie present the results to those involved?
SELECT ONE OPTION
A. The percentage of completed transactions is close to the acceptance value, an improvement is required. The transactions associated with the check-in are close to the acceptance value, no Improvement is required.
B. The percentage of completed transactions is close to the acceptance value, no improvement is required. The transactions associated with the check-in are below the acceptance value, no improvement is required.
C. The percentage of completed transactions is close to the acceptance value, an improvement is required. The transactions associated with the check in are below the acceptance value, an improvement is required.
D. The percentage of completed transactions is so close to the acceptance value that no improvement is required. The transactions associated with the check-in are below the acceptance value, a minimum improvement is required.

Each installation shall have a high processing capacity.
Question specific constraints: (specific constraints are not part of the Base Scenario and are specific to this question).
* The project follows a sequential development life cycle model.
Question
Which is the right moment in the project to analyze and evaluate the performance risks?
SELECT ONE OPTION
A. Repeatedly throughout the development phases (including requirements activities) and the performance test itself.
B. During the analysis and design activities as well as, again, before each performance test cycle.
C. After design but before coding.
D. During the requirements activities and again before running the performance test.
正解:A
