Consider the following command: dispadmin -c IA -g -r 1000000 Which statement correctly describes the result?

Question

Options

• AThe quantum will be reported in milliseconds.
• BThe quantum will be output every 1000000 milliseconds.
• CThe quantum will be reported in microseconds.
• DThe quantum will be output every 1000000 microseconds.

• A
  4% (2)
• B
  8% (4)
• C
  87% (45)
• D
  2% (1)

Explanation

Option C is correct because the -r flag in dispadmin specifies the resolution as ticks per second - a value of 1,000,000 means one million divisions per second, which equals microsecond (µs) granularity (1/1,000,000 of a second). The quantum values in the output are then expressed in that unit.

Why the distractors fail:

• A is wrong because millisecond resolution would require -r 1000 (1,000 ticks/sec = 1 ms), not 1,000,000.
• B and D are wrong because -r has nothing to do with how often output is produced - it controls the unit of measurement, not a polling interval.

Memory tip: Think of -r as "resolution = reciprocal of time unit." -r 1000 → 1/1000 sec = milliseconds; -r 1000000 → 1/1,000,000 sec = microseconds. Each factor of 1,000 moves you one prefix smaller.
