The following exhibit shows the parts of the plugin-cfg.xml file that are relevant for myApp. The UriGroups for other applications are not shown in the exhibit.
What should the administrator do to the plugin-cfg.xml file to ensure that requests for default_host_myApp URIGroup are routed only to machine1?
A. Delete the server tag for Cloneld="b20000002" Delete all of the tags within the Server tag
B. Delete the UriGroup tag for default_host_myApp Delete all of the tags within this UriGroup tag
