Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 490

What is a characteristic of traffic shaping?

Answer options

• A. drops out-of-profile packets
• B. causes TCP retransmits when packets are dropped
• C. can be applied in both traffic directions
• D. queues out-of-profile packets until the buffer is full

Correct answer: D

Explanation

The correct answer is D because traffic shaping involves queuing out-of-profile packets until they can be transmitted, which helps manage bandwidth. Option A is incorrect as traffic shaping typically does not drop packets but rather queues them. Option B is wrong because while dropped packets may lead to retransmits, that is not a characteristic of traffic shaping itself. Option C is misleading as traffic shaping is usually focused on one direction at a time for effective management.
