Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 305

Under which condition does UDP dominance occur?

Answer options

• A. when TCP traffic is in the same class as UDP
• B. when UDP flows are assigned a lower priority queue
• C. when WRED is enabled

Correct answer: T, C, P

Explanation

UDP dominance occurs when WRED is enabled, allowing for preferential treatment of UDP traffic under certain conditions. Option A is incorrect as TCP traffic being in the same class as UDP does not guarantee UDP dominance. Option B is also wrong because lower priority for UDP would not lead to dominance.
