Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 79
An engineer is describing QoS to a client.
Which two facts apply to traffic policing? (Choose two.)
Answer options
- A. Policing should be performed as close to the source as possible.
- B. Policing adapts to network congestion by queuing excess traffic.
- C. Policing should be performed as close to the destination as possible.
- D. Policing drops traffic that exceeds the defined rate.
- E. Policing typically delays the traffic, rather than drops it.
Correct answer: A, D
Explanation
The correct answers are A and D because traffic policing is best implemented close to the source to effectively manage the traffic flow and it is designed to drop packets that exceed the defined rate. Option B is incorrect as policing does not queue excess traffic, and option E is wrong since policing typically drops traffic rather than delaying it.
