The correct answer is B. The VoIP traffic on the core link exceeds 1 Gb/s and is dropped by the policer. D. The VoIP traffic on this core link is MPLS-labeled and is not subject to QoS. See the full explanation below for the reasoning.
Question
Refer to the exhibit. You are operating a converged network that is used to provide multiple types of services including VoIP. You have received multiple complaints that the call quality for some of the calls is poor. You determine that all calls with a reported problem transit via one common link in the core. This link interconnects two CRS-1 core routers. The exhibit shows the QoS configuration of the port on both CRS-1 routers. What are the two most likely reasons for the problem? (Choose two.)
Options
- AThe bandwidth that is allocated in the QoS configuration is more than 100 percent and is probably
- BThe VoIP traffic on the core link exceeds 1 Gb/s and is dropped by the policer.
- CThe core link is congested due to VoD and IPTV traffic and is causing starvation to VoIP traffic.
- DThe VoIP traffic on this core link is MPLS-labeled and is not subject to QoS.
- EA DoS attack on the CRS has caused high CPU utilization on the line card that hosts the 10 Gigabit
