A.
Increased availability of network services due to higher throughput

B.
Longer MTBF of hardware due to lower operating temperatures

C.
Higher data integrity due to more efficient SSD cooling

D.
Longer UPS run time due to increased airflow

Explanation:
The mean time between failures (MTBF) is the measure of the anticipated incidence of failure for a system or
component. This measurement determines the component’s anticipated lifetime. If the MTBF of a cooling
system is one year, you can anticipate that the system will last for a one-year period; this means that you
should be prepared to replace or rebuild the system once a year. If the system lasts longer than the MTBF, your
organization receives a bonus. MTBF is helpful in evaluating a system’s reliability and life expectancy. Thus
longer MTBF due to lower operating temperatures is a definite advantage
