   A performance test team is planning the activities for a new system. The system will be used by both internal employees and external customers. The internal users are on a fast corporate network, while external customers use various internet connections. The team needs to define realistic load profiles. What is the MOST appropriate approach?

   • AUse a single load profile based on the internal users' network conditions, as they are more predictable.
   • BRun two separate tests, one for internal users and one for external users, and report the results separately.
   • CUse a single load profile based on the external users' network conditions, as they are the majority.
   • DCreate separate load profiles for internal and external users, with different network conditions and think times, and combine them in the test.

   A performance test team is preparing to test a mobile banking application. The test plan specifies that the test must simulate realistic user behavior, including think time and varying network conditions. The team has completed scripting and is now ready to execute. What is the NEXT task in the performance testing process?

   • AUpdate the test plan to include the network conditions that were just discovered.
   • BAnalyze the results from the previous test run to identify bottlenecks.
   • CRun a smoke test with a small number of virtual users to verify that the scripts execute correctly and the environment is stable.
   • DImmediately run the full load test with the target number of virtual users to save time.

   A performance test team has just completed a load test. The results show that response times increased significantly at 80% of the target load. The team needs to identify the cause. What is the MOST appropriate next task?

   • AReport the results to stakeholders and recommend increasing the server capacity.
   • BImmediately rerun the test with a higher load to confirm the results are reproducible.
   • CAnalyze the monitoring data from the application server, database, and network to correlate the response time increase with resource utilization.
   • DModify the test script to reduce the think time and rerun the test.

   During the requirements phase of a project, a product owner asks the performance test team to define the expected response time for a new search feature. The team has no historical data for this feature. What is the most appropriate performance testing activity to perform in this phase?

   • ADefer all performance work until the system is in production and then monitor real user response times.
   • BExecute a load test against a prototype to measure the actual response time and use that as the baseline.
   • CConduct a stakeholder workshop to elicit and document non-functional requirements such as response time, throughput, and load profiles.
   • DAsk the development team to estimate response time based on their knowledge of the codebase.

   A team is in the implementation phase of a project. Developers have just completed a new feature that adds a complex search function. The performance test team wants to test this feature early. What is the MOST appropriate activity?

   • AWait until the feature is integrated into the main branch and then run a full regression performance test.
   • BSkip performance testing for this feature because it is too small to affect overall performance.
   • CRun a targeted performance test on the new search feature in the development environment to identify any obvious issues.
   • DAsk the developer to estimate the performance impact of the feature and document it in the test plan.
