Your network environment includes a Microsoft Visual Studio Team Foundation Server (TFS) 2012 server. You create a new project using the default Visual Studio Scrum 2.0 template. You want to inform the product owner when a Product Backlog Item (PBI) is ready for testing. You need to ensure that when the development of a PBI has been completed, the tester is able to change the state of the item to be Ready for Acceptance Testing. You need to achieve this goal without developing custom code. What are two possible ways to accomplish this goal? (Each correct answer presents a complete solution. Choose two.)
A. Use the TFSFieldMapping command to map a new state for Product Backlog Item.
B. Use the Visual Studio Process Template editor to modify the Product Backlog Item template.
C. Write a Visual Studio Extension (VSIX) so developers can change the state in Visual Studio.
D. Modify the Product Backlog Item template XML and use the witadmin command to import the modified XML.
