Question
What is a characteristic of traffic shaping?
A. lacks support for marking or remarking
B. must be applied only to outgoing traffic
C. can be applied in both traffic directions
D. queues out-of-profile packets until the buffer is full
Answer
C. can be applied in both traffic directions
Explanation
Traffic shaping is a technique used to control and manage network traffic by adjusting the speed of traffic flow. One of the key characteristics of traffic shaping is that it can be applied in both incoming and outgoing traffic directions.
Traffic shaping allows network administrators to:
- Prioritize critical traffic
- Limit bandwidth for specific applications or users
- Smooth out traffic bursts to prevent network congestion
- Ensure fair bandwidth allocation among different traffic types
Unlike some other traffic management techniques, traffic shaping supports marking or remarking of packets, allowing for granular control over traffic prioritization.
When traffic exceeds the configured rate limit, traffic shaping queues the excess packets in a buffer until the rate falls below the limit, rather than immediately dropping them. This helps prevent buffer overflow and maintains network stability.
In summary, traffic shaping is a powerful tool that can be applied bi-directionally to efficiently manage network bandwidth, prioritize critical traffic, and prevent congestion, making it an essential concept for the Cisco CCNP 350-401 certification exam.
