Q2. How is pressurization maintained in the cabin of an A320? 

Ans: Pressurization is maintained with the help of the outflow valve. 

The outflow valve is on the right-hand side of the fuselage, behind the aft cargo compartment and below the flotation line.

It is regulated and controlled automatically through CPC computers and helps the cabin air to escape at a controlled rate to maintain the required differential pressure
