Read your requirements and always check with the proctor first. Static mroutes are really meant to override unicast information. There may be scenarios that exist that enable multicast routing on interfaces the IGP does not choose as the route. In these scenarios, state your case clearly to the proctor and you should have no issue.

The answer is "IT DEPENDS". The exam will clearly call out what is allowed / disallowed in the exam. If it isn't clear, then you should ask the proctor.
