Exhibit:As shown in the figure, complex traffic classification is configured for RTA's upstream GigabitEthernet 1/0/0. The QoS is configured as follows:A tester sends TCP packets from GE 1/1 to GE 1/2 at 40 1.2.2 IF DSCP values of packets GE receives are not 46, what are the possible causes?
Answer(s): B
The inner VLAN tag in layer 2 user packets is used to differentiated key services from other services. If packets are not processed after being encapsulated by QinQ, the 802. 1p information of the inner VLAN tag becomes invalid. After the QinQ is employed, three methods can be used to configure conditions for sensing 8021p configuration of the inner VLAN tag:1. Reset the 802.1p of the outer VLAN tag regardless of the existing 02 1p configurations of the inner VLAN tag.2. Automatically swap the 802. 1p configurations of the inner VLAN tag to that of the outer VLAN tag.3. Reset the 802.1p configurations of the outer VLAN tag based on the existing 802.1p configurations of the different VLAN tags
Answer(s): A
On a router, HQoS parameter are configured for the users. The CURP of user 1 is Mbit/s. The CUR and PIR of user 2 are 0 Mbit/s and 10 Mbit/s, respectively. The CIR and PR of user 3 are 0 Mbit and 20 Mbit/s respectively. These three users join group with a bandwidth of 10 Mbit/s.Which statements is true?
Answer(s): C
Exhibit:RTA is an edge router of the MPLS backbone network. It provides the access services for users under Layer 2 switches and different users by subinterface . User A access VLAN 12 and has subscribed to the His, VoIP, and IPTV services. According to 802 1p priorities, the value indicates the His service, 1 indicates the VoIp service, and 4 indicates the IPTV service. RTA is configured on he access side as follows.What is the descending order of service priorities?
Answer(s): D
An interface sends 300 Mbit/s user BE traffic. The downstream HQoS scheduling is configured at this interface as followsSQ: cir 15 Mbit/s pw 200 Mbit/sFQ. queue be Ipq shaping 10CQ: port-queue be Ipq shaping shaping-percentage 10 outbound, port shaping 100 How much traffic is at the downstream outbound interface after HQoS scheduling?
