Under which condition does UDP dominance occur?
when TCP traffic is in the same class as UDP
when UDP flows are assigned a lower priority queue
when WRED is enabled
when ACLs are in place to block TCP traffic
Which two actions must you perform to enable and use window scaling on a router? (Choose two)
Execute the command ip tcp window-size 65536.
Set window scaling to be used on the remote host.
Execute the command ip tcp queuemax.
Set TCP options to “enabled” on the remote host.
Execute the command ip tcp adjust-mss.
Which three TCP enhancements can be used with TCP selective acknowledgments? (Choose three)
explicit congestion notification
TCP path discovery
A network engineer notices that transmission rates of senders of TCP traffic sharply increase and decrease simultaneously during periods of congestion. Which condition causes this?
random early detection
queue management algorithm
Which three problems result from application mixing of UDP and TCP streams within a network with no QoS? (Choose three)
A network administrator uses IP SLA to measure UDP performance and notices that packets on one router have a higher one-way delay compared to the opposite direction. Which UDP characteristic does this scenario describe?
nonsequencing unordered packets
A network engineer is configuring a routed interface to forward broadcasts of UDP 69, 53, and 49 to 172.20.14.225. Which command should be applied to the configuration to allow this?
router(config-if)#ip helper-address 172.20.14.225
router(config-if)#udp helper-address 172.20.14.225
router(config-if)#ip udp helper-address 172.20.14.225
router(config-if)#ip helper-address 172.20.14.225 69 53 49
Which traffic characteristic is the reason that UDP traffic that carries voice and video is assigned to the queue only on a link that is at least 768 kbps?
typically is not fragmented
typically is fragmented
causes excessive delays for video traffic
Which two attributes describe UDP within a TCP/IP network? (Choose two)
A network engineer wants to ensure an optimal end-to-end delay bandwidth product. The delay is less than 64 KB. Which TCP feature ensures steady state throughput?
