What does each virtual user use during every loop when the open mode of a datapool is set to privatewith no wrap?(i.e. the wrap check box is unchecked)?A. a unique row from the datapool because the test will not retrieve restart from the beginning of thedatapool when the end of the datapool is reachedB. a private view of the datapool with unique rows apportionedC. a private view of a datapool with values that can be reused by other virtual usersD. a private view of a datapool assigned per agent machineAnswer: C27. A customer recently purchased RPT. The playback tests appear to have passed in the Test ExecutionHistory. However, upon closer inspection using the Protocol Data view, some pages following the datapoolsubstitution failed.What is the most likely cause of this problem?A. The datapool was opened in the wrong shared mode.B. The datapool variable was substituted with the incorrect test element.C. The datapool was not checked with a verification point.D. The datapool value was substituted, but not fully correlated.Answer: D28. if the automatic data correlation for execution is set to efficiency and the datapools are open in privatemode, test execution will be _____.A. faster, but datapool values will not be unique for each virtual testerB. faster, and datapool values will be unique for each virtual testerC. slower, but datapool access will be fast because of private viewsD. slower because the correlated values are substituted from the nearest previous referenceAnswer: Awww.Prepking.com
