Question 5

You are a software tester that is testing a complex application that is running within a single virtual machine. You have recently encountered a rare and intermittent software defect that developers have been unable to reproduce or troubleshoot in the past. Which of the following steps should you take to allow developers to recreate the issue?

a. Power off the virtual machine and discard any saved state information.

b. Save the state of the virtual machine and provide a copy of it to your developers to troubleshoot the problem.

c. Roll back the state of the virtual machine to a point in time prior to when the defect was discovered.

d. Move the virtual machine to another host server to which developers have access.

 

Answer: b 

Explanation: One of the primary benefits of virtualization is the ability to save the state of a VM and then move or copy it to another location. This is particularly helpful when troubleshooting intermittent problems or those that are hard to reproduce.
