A is correct. The max number of machines used is 5. It doesn't matter the number of process, each license is distributed to each machine. At my employer we have 12 licenses and over 30 processes that run across those 12 machines.

B is correct

Answer is B Look in Control Room at the number of sessions that are concurrently running. It doesn't matter which process it is or which runtime resource(s) is being used. The license consumption/limitation is purely calculated by adding up the total number of sessions that are active in some way, which includes pending, running, warning, stopping, etc. So, basically all sessions that are other than Completed, Terminated, or Stopped are counted up and that's the license usage. If you have 1 runtime resource running 2 sessions, then that's 2 "licenses" consumed. If you have 2 runtime resources running 1 session each, then that's 2 licenses consumed. If you have 2 runtime resources with 2 sessions each, then that's 4 licenses consumed.

5 is the ans

shouldn't the answer be B -> 9+1+2 = 12
