different port.
For quota limits, we can adjust my.cnf to control each instance's memory
usage, also can use cgroups to set CPU quota.

Ahmed, do you have more connections than you

An interface by definition is a point of interconnection.

John,
I don't want to argue too much on this but I'd also like the opinion of the

For the purposes of the exam, which I think the original question related
to, I would say you have to accept mysql's interpretation of 'network

you on.
Would you kindly supply the changes you made, for our collective education?
