Which of the following increases system reliability?
A.
A lower MTBF and a lower MTTR
B.
A higher MTBF and a lower MTTR
C.
A lower MTBF and a higher MTTR
D.
A higher MTBF and a higher MTTR
Explanation:
Mean-time-between-failures (MTBF) is the average length of time the
hardware is functional without failure. Mean-time-to-repair (MTTR) is the amount of
time it takes to repair and resume normal operation after a failure has occurred.
Having a higher MTBF and a lower MTTR will increase equipment�s reliability, thus
increasing the system�s overall reliability.
