  Pretty simple maths: MTTD stays 5 as no change in it MTTR doubles to 20 minutes because question says "a new database system that takes twice as long to successfully fail over between zones." MTBF stays the same i.e., once per quarter (90 days) Impact: 33% because if one zone fails, only users in that zone is affeted and we have users spread over 3 zones.

  Impact would be 33% since failure is one zone out of three zones (1/3)
