Which of the following descriptions of quota control strategies is incorrect?

Question

Options

• AThe quota control policy can only limit the amount of users' Internet traffic.
• BThe quota control strategy consists of two parts: detection and control.
• CQuota control policy can limit the maximum bandwidth
• DQuota control policy can detect Internet traffic in real time

• A
  75% (15)
• B
  5% (1)
• C
  15% (3)
• D
  5% (1)

Explanation

Option A is incorrect because quota control policies are not limited to controlling only the amount (volume) of Internet traffic - they are more versatile than that. Quota control strategies can also limit maximum bandwidth (as stated in C) and can detect Internet traffic in real time (as stated in D), making both C and D accurate descriptions. Option B is also correct: a quota control strategy is fundamentally composed of two components - the detection phase (monitoring and measuring traffic) and the control phase (enforcing the configured limits).

Memory tip: Think of quota control as a "traffic cop with multiple tools" - it can watch traffic in real time (D), has a detection unit and enforcement unit (B), and can restrict both how fast (bandwidth) and how much (volume), not just one or the other (which is why A is wrong).
