In MTBF, higher values indicate what about a component?

• A. Faster repair times
• B. Greater reliability
• C. Shorter downtime
• D. More data loss

Answer: (C)

Mean Time Between Failures (MTBF) measures how long a component operates on average before a failure occurs. A higher MTBF means longer time between failures, which corresponds to lower failure frequency and higher reliability. MTBF doesn’t tell you how long a repair takes—that’s a separate metric (MTTR, the mean time to repair). Downtime is influenced by both how often failures happen and how long repairs take, so while a higher MTBF can reduce downtime over time, it doesn’t directly indicate shorter repair times. Therefore, the best interpretation is greater reliability. The other options describe repair speed, immediate downtime, or data loss, which aren’t directly determined by MTBF.
