The correct answer is A. The trust upstream default command maps the DSCP priority to the corresponding EXP value C. The port-queue ef pq shaping 20 outbound command configures PQ scheduling and a maximum. See the full explanation below for the reasoning.
Question
The edge routers of the MPLS network, partial interface configurations on the IP access side are as follows:
[Quidway]diffserv domain default [Quidway-dsdomain-default]ip-dscp-inbound 10 phb ef green [Quidway-dsdomain-default]mpls- exp-outbound ef green map 5 [Quidway-dsdomain-default]mpls-exp-inbound 4 phb ef green [Quidway-dsdomain-default]ip-dscp-outbound ef green map 18 [Quidway-dsdomain- default]quit[Quidway] interface GigabitEthernet 2/0/0 [Quidway-GigabitEthernet2/0/0] trust upstream default [Quidway-GigabitEthernet2/0/0] port-queue ef pq shaping 20 outbound Which of the following statements about the preceding configurations are true?
Options
- AThe trust upstream default command maps the DSCP priority to the corresponding EXP value
- BIf an IP packet with a DSCP value of 10 is sent to the MPLS network (non-PHP node) from
- CThe port-queue ef pq shaping 20 outbound command configures PQ scheduling and a maximum
