   A TCP-based application is experiencing intermittent delays and reduced throughput. The network shows a small percentage of packets are being dropped. What is the most likely effect of this packet loss on the application?

   • AIncreased jitter
   • BRetransmissions and reduced throughput
   • CNo impact if the application is TCP-based
   • DHigher bandwidth utilization

   During peak hours, a network link becomes saturated with traffic. Users report that web pages load slowly and some requests time out. Which sequence of events best describes what happens during network congestion?

   • AReduced delay, then packet loss, then increased throughput
   • BPacket loss, then increased bandwidth, then reduced delay
   • CIncreased delay, then packet loss, then reduced application performance
   • DIncreased bandwidth, then reduced delay, then improved performance

   A financial trading firm has offices in New York and London. The application requires one-way latency of less than 65 ms. The current WAN link has a propagation delay of 40 ms, but the total latency is 80 ms due to router processing and queueing. What is the most effective way to reduce the latency to meet the requirement?

   • AOptimize router configurations to reduce processing and queueing delays.
   • BUpgrade the WAN link to a higher bandwidth connection.
   • CMove the application servers to a third location to reduce distance.
   • DUse TCP acceleration to speed up the application.
