Questions # 11:

You're setting up a folder config in Jenkins, and you set a couple of items called "child item with worst health" and "recursive." A colleague turns to you, since you know the answers to the rest of his questions, and asks you, "how do I determine the health of the folder with those items set?What's your answer?

Options:

Only top scoped projects will determine the health of a folder.

I don't know. Ask someone else.

Items in nested sub-folders are used to calculate the folders health.

Don't be silly. Folder's don't have health.

Answer

Explanation

When a folder is configured to recursive and "child item with worst health" is selected, the item in the recursive folder structure will be used to determine the folder's health.
