New Questions 7
Addressing QoS design in the Enterprise Campus network for IP Telephony applications means what?
A. It is critical to identify aggregation and rate transition points in the network, where preferred traffic and congestion QoS policies should be enforced
B. Suspect traffic should be dropped closest to the source, to minimize wasting network resources
C. An Edge traffic classification scheme should be mapped to the downstream queue configuration
D. Applications and Traffic flows should be classified, marked and policed within the
Enterprise Edge of the Enterprise Campus network
Answer: A
Explanation: https://www.cisco.com/c/en/us/support/docs/switches/catalyst-4500-series- switches/69632-configuring-cat-ip-phone.html#topic1
When you connect an IP phone to a switch using a trunk link, it can cause high CPU utilization in the switches. As all the VLANs for a particular interface are trunked to the phone, it increases the number of STP instances the switch has to manage. This increases the CPU utilization. Trunking also causes unnecessary broadcast / multicast / unknown unicast traffic to hit the phone link. In order to avoid this, remove the trunk configuration and keep the voice and access VLAN configured along with Quality of Service (QoS). Technically, it is still a trunk, but it is called a Multi-VLAN
Access Port (MVAP). Because voice and data traffic can travel through the same port, you should specify a different VLAN for each type of traffic. You can configure a switch port to forward voice and data traffic on different VLANs. Configure IP phone ports with a voice VLAN configuration. This configuration creates a pseudo trunk, but does not require you to manually prune the unnecessary VLANs.
