Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 322

Which three problems result from application mixing of UDP and TCP streams within a network with no QoS? (Choose three.)

Answer options

• A. starvation
• B. jitter
• C. latency
• D. windowing
• E. lower throughput

Correct answer: A, C, E

Explanation

Starvation occurs when one type of traffic is prioritized over another, leading to delays or drops. Latency is introduced due to the different handling of TCP and UDP, causing delays in data transmission. Lower throughput results from the inefficiencies created by mixing the two protocols without QoS, where TCP's congestion control mechanisms can limit overall network performance.
