segments warn of excessive jitter, delay, and in some cases packet retransmissions. ?There is a pair of
switches that all traffic converges upon. The link between the two switches is a 100/Full Fast Ethernet
connection that is operating at near maximum capacity for the majority of the day. ?At any given time, the
estimated traffic on the link between the two switches is 200 Mbps. Which two configuration changes will
improve the voice quality of the VoIP calls and prevent possible VoIP issues in the future between these
two switches? (Choose two.)
A. Place a router between the two switches and configure the 100 Mbps links to the two switches with a
higher QoS for VoIP traffic.
B. Prioritize the traffic on the switches to give VoIP improved QoS. Prioritize only the traffic on the
switches to give VoIP calls improved QoS.
C. Provide a larger aggregated bandwidth of 300 Mbps by trunking three interfaces together on the two
switches using Multilink Trunks (MLTs).
D. Purchase two new Layer 2 switches that are capable of gigabit Ethernet to replace the Fast Ethernet
connection with a single gigabit Ethernet connection.
