Question No. 1
When troubleshooting LDP operations on the Cisco IOS and IOS XE routers, what is one of the first things that should be verified?
Question No. 2
Which QoS mechanism is used for congestion avoidance?
Question No. 3
DS-TE implementations on Cisco routers support which bandwidth pool(s) and class type(s)? (Choose two.)
Differential Service Tunnels
Differential Service Traffic Engineering (TE) is an extension of the regular MPLS Traffic Engineering (MPLSTE) feature. Regular TE does not provide bandwidth guarantees to different traffic classes. A single bandwidth pool (global pool) is used in regular TE that is shared by all traffic. In order to support various class of service (CoS), the ability to provide multiple bandwidth pools is required. These bandwidth pools then can be treated differently based on the requirement for the traffic class using that pool.
In RSVP global and subpools reservable bandwidths are configured on a per interface basis to accommodate TE tunnels on the node. Available bandwidth from all configured bandwidth pools is advertised using Interior Gateway Protocol (IGP). RSVP is used to signal the TE tunnel with appropriate bandwidth pool requirements.
Question No. 4
Which option is the appropriate way to configure a color-aware, dual-rate policer together with a color-blind, single-rate policer for the rest of the traffic?
Question No. 5
A network engineer must analyze RSVP-TE signaling on a syslog server. Whichthree RSVP messages are valid? (Choose three.)
Question No. 6
Which configuration can a network engineer use to establish high availability for LDP in an MPLS setup?
