A network engineer is tasked with supporting traffic discrimination over MPLS traffic engineering tunnels.
To allocate restricted bandwidth to a certain type of traffic with no QoS degradation, which technique must be used?

Refer to the exhibit. Router BRDR-1 is configured to receive the 0.0.0.0/0 and 172.17.1.0/24 networks via BGP and advertise them into OSPF area 0. An engineer has noticed that the OSPF domain is receiving only the 172.17.1.0/24 route and default route 0.0.0.0/0 is still missing. Which configuration must an engineer apply to resolve the problem?

Refer to the exhibit. Tier 2 ISP A on AS 653 is connected to two Tier 1 ISPs on AS 321 and AS
51 respectively. The network architect at ISP A is planning traffic flow inside the network to provide predictable network services. Cisco Express Forwarding is disabled on the edge router.
How should the architect implement BGP to direct all traffic via the Tier 1 ISP with next-hop
7.4.5.2?

A company needs to improve the use of the network resources that is used to deploy internet access service to customers on separate backbone and internet access network.
Which two major design models should be used to configure MPLS L3VPNs and internet service in the same MPLS backbone? (Choose two.)

Refer to the exhibit. If the SP network is configuring RTBH filtering to protect hosts on the
152.68.19.0/24 network, which router should be configured as the black hole activating router?
