An architect must address sustained congestion on the access and distribution uplinks of a network. QoS has already been implemented and optimized, but it is no longer effective in ensuring optimal network performance. Which two solutions should the architect use to improve network performance. (Choose two.)
Answer(s): B,D
An engineer must design a QoS solution for a customer that is connected to an ISP over a 1Gbps link with a 100Mbps CIR. The ISP aggressively drops all traffic received over the CIR, which is causing numerous TCP retransmissions. The customer is not using any RTP applications but wants to maximize bandwidth usage up to the CIR. Which QoS solution should the engineer choose?
Answer(s): C
The customer solution requires QoS to support streaming multimedia over a WAN. An architect chooses to use Per-Hop Behavior. Which solution should the engineer use to classify and mark traffic traveling between branch sites?
An engineer must design an in-band management solution for a customer with branch sites. The solution must allow remote management of the branch sites using management protocols over an MPLS WAN. Queueing is implemented at the remote sites using these classes:-Class1 equals voice traffic-Class2 equals mission-critical traffic-Class3 equals default trafficHow must the solution prioritize the management traffic over the WAN?
Answer(s): D
