Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 17

Under which circumstance can TCP starvation occur?

Answer options

• A. when HTTP and HTTPS traffic are transmitted on the same link
• B. when TCP and UDP traffic are mixed in the same class of service
• C. when DNS TFTP traffic are transmitted on the same link
• D. when UDP traffic is processed in a policy-map before TCP traffic
• E. when TCP traffic is blocked by an ACL

Correct answer: D

Explanation

TCP starvation can occur when UDP traffic is prioritized over TCP traffic in a policy-map, which can lead to TCP not receiving enough bandwidth to function effectively. The other options do not directly lead to TCP starvation; mixing traffic types or blocking does not necessarily prioritize one over the other as is the case in option D.
