What QoS technology allows traffic to pass even though it has exceeded the bandwidth limit but will be queued later?

Question

Options

• AShaping
• BPolicing
• CWeighted Fair Queuing
• DLow Latency Queuing

• A
  89% (16)
• B
  6% (1)
• C
  6% (1)

Explanation

Traffic shaping (A) is designed to smooth traffic bursts by buffering excess traffic in a queue when the rate exceeds the configured limit, then transmitting that queued traffic later when bandwidth is available. This contrasts with policing (B), which drops or re-marks excess traffic immediately rather than queuing it-traffic that exceeds the policed rate is discarded or marked down and does not pass. Weighted Fair Queuing (C) is a scheduling mechanism that shares bandwidth fairly among flows but does not specifically buffer traffic that has exceeded a rate limit. Low Latency Queuing (D) prioritizes delay-sensitive traffic but also does not buffer exceeded-rate traffic for later delivery.
