Difficulty: Easy
Correct Answer: /s
Explanation:
Introduction / Context:
SMARTDrive (SMARTDRV.EXE) is a DOS/Windows 3.x era disk caching utility that accelerates disk access by buffering reads and writes. Knowing its command-line switches is important when tuning legacy systems or analyzing performance and write-caching behavior.
Given Data / Assumptions:
Concept / Approach:
The summary/statistics switch prints the current cache configuration (cache sizes, write-behind state) and counters. This is typically invoked at the command prompt to verify settings after AUTOEXEC/CONFIG configuration changes.
Step-by-Step Solution:
Verification / Alternative check:
Running SMARTDRV without parameters after loading often displays a brief status; explicitly adding /S prints a fuller summary of cache settings and hits/misses on many versions, which technicians use to confirm effective caching.
Why Other Options Are Wrong:
Common Pitfalls:
Assuming /x shows information because it changes behavior. Also, confusing the informational output shown when SMARTDRV is run with no parameters with the explicit statistics output requested here.
