Based on the exhibit, which statement is true about the applied QoS policy?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Video traffic is being dropped at a rate of 5 kbps.

The exhibit shows that the video class has a police rate of 20 kbps and an exceed rate of 5 kbps, indicating that 5 kbps of video traffic is being dropped due to the policer. Option A is false because the voice class has no drops. Option B is false because the policy does not use low-latency queuing (LLQ); it uses policing instead. Option D is false because voice traffic shows zero drops.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The default class matches only best-effort traffic.

    Why it's wrong here

    The default class matches 'any', including all traffic not matched by other classes.

  • The policy uses low-latency queuing for voice.

    Why it's wrong here

    No priority or LLQ is shown; only policing is applied.

  • Video traffic is being dropped at a rate of 5 kbps.

    Why this is correct

    The video class shows an exceed rate of 5 kbps, confirming drops.

  • Voice traffic is experiencing drops due to policer.

    Why it's wrong here

    Voice traffic shows zero exceeded packets, so no drops.
