You are using a base Jenkins master in production with the recommended set of plugins.
The administrators have configured a Global Pipeline Library named "common-libs", stored in a git repository, with the configuration shown in the exhibit above.
You have a Pipeline job at the root of the Jenkins dashboard, whose script starts with the annotation @LibraryCcommon-libs') _
You want to test this Pipeline job with a beta version of the Global Pipeline Library "common-libs", stored on the branch named ‘’edge’’ the git repository.
Which of the following statements are TRUE? Choose 2 answers

A.Replace the @ Library ('common- lib.'_ annotation with QLibrary('common-libs@edge') and run the job again.
B.Duplicate the Pipeline job in a folder with a local Global Pipeline Library referencing the git repository on the "edge" branch, and change libs')_ annotation to ^Library ('common-libs: edge1) Replace the ommon-libs1)_ annotation with ^Library (' common -libs: edge')_ and run the job again.
C.Duplicate the pipeline job in a folder with a local Global Pipeline Library referencing the git repository on the "edge" branch, and change its annotation to ^Library (' common - libs@edge' )
