This was one of the questions I brought to
the proctors. They were very helpful in clearing up things like this.
My advice would be to do what the lab says, but don't hesitate to clarify
if the paper is not clear or doesn't say. I know I always worked for full
connectivity between all routes in my practice labs, but it may not be
necessary in the real lab.
