the downside to fault tolerance is the cost associated with duplicate devices and services
that might never be needed or used.
balancing the cost of duplicate devices, we need to consider mtbf and mttr. although not
a direct expenditure, each of these is a cost to our network when the device is not available.

average amount of time that will pass for devices exactly like this one before the next failure is expected to occur.
average amount of time to repair a device.
mttr

Explanation:

MTBF stands for Mean Time Between Failures. It is calculated as the average time between successive failures of a device. So, it represents the average amount of time that will pass for devices exactly like this one before the next failure is expected to occur.

MTTR stands for Mean Time To Repair. It is the average time required to repair a failed device. So, it represents the average amount of time to repair a device.

Answer:

MTBF: Average amount of time that will pass for devices exactly like this one before the next failure is expected to occur.

MTTR: Average amount of time to repair a device.
