You are tasked to design a QoS policy for a service provider so they can include it in the design of their MPLS core network If the design must support an MPLS network with six classes, and CEs will be managed by the service provider, which QoS policy should be recommended?

1. A. map IP CoS bits into the IP Precedence field
2. B. map flow-label bits into the Exp field
3. C. map IP precedence bits into the DSCP field
4. D. map DSCP bits into the Exp field

Correct Answer: D

A business requirement stating that failure of WAN access for dual circuits into an MPLS provider for a Data Centre cannot happen due to related service credits that would need to be paid has led to diversely routed circuits to different points of presence on the providers network? What should a network designer also consider as part of the requirement?

1. A. Provision of an additional MPLS provider
2. B. Out of band access to the MPLS routers
3. C. Ensuring all related remote branches are dual homed to the MPLS network
4. D. Dual PSUs & Supervisors on each MPLS router

Correct Answer: A

Company XYZ is running OSPF in their network. They have merged with another company that is running EIGRP as the routing protocol. Company XYZ now needs the two domains to talk to each other with redundancy, while maintaining a loop free environment. The solution must scale when new networks are added into the network in the near future. Which technology can be used to meet these requirements?

1. A. multipoint route-redistribution with route filtering using ACLs
2. B. DUMP multipoint route-redistribution with route filtering using route tags
3. C. DUMPS single point route-redistribution with route filtering using route tags
4. D. DUMPS single point route-redistribution with route filtering using ACLs

Correct Answer: B
