   A company is deploying a new video conferencing system. The network team must ensure the system performs well. The video application requires a maximum one-way latency of 150 ms and jitter under 30 ms. The WAN link has an average latency of 120 ms and jitter of 40 ms. What should the network team do?

   • AAccept the current performance because latency is within the limit.
   • BIncrease the WAN bandwidth to reduce latency.
   • CImplement QoS to reduce jitter by prioritizing video traffic.
   • DSwitch to a different video codec that requires less bandwidth.

   A company is deploying a cloud-based application that requires a round-trip time (RTT) of less than 100 ms. The network team is choosing between two cloud providers. Provider A has a data center 500 miles away with an RTT of 80 ms. Provider B has a data center 100 miles away with an RTT of 40 ms but experiences occasional packet loss of 2%. Which provider is more suitable?

   • AChoose Provider B and rely on TCP retransmissions to handle the packet loss.
   • BUse both providers and route traffic to the one with the lowest RTT at any time.
   • CProvider A, because the RTT is within the requirement and the connection is more stable.
   • DProvider B, because the RTT is lower.
