Refer to the exhibit. An engineer is configuring new Cisco MPLS TE tunnels between routers A and F and must prevent the TE tunnel from using any of the 10G interface, while also allowing for oversubscription of the 100G link. Which strategy achieves the configuration requirements?

• A.Implement bandwidth reservations on the tunnels.
• B.Configure link attributes and tunnel affinities.
• C.Implement the 100G links in an auto-tunnel mesh.
• D.Configure the 10G interfaces into a shared risk link group.

An engineer has been tasked to configure a guaranteed 2 Mbps of bandwidth for outgoing FTP traffic on interface FastEthernet 1/1/1 on Cisco IOS XR. Which method accomplishes this configuration?

• A.configure terminal
  access-list 100 permit ip any any eq 21
  policy-map POLICY_1
  match ip access-list 100
  bandwidth 2000
  exit
  exit
  interface FastEthernet 1/1/1
  service-policy output POLICY_1
  end

• B.configure terminal
  policy-map POLICY_1
  class FTP_CLASS
  match protocol ftp
  bandwidth 2000000
  exit
  exit
  interface FastEthernet 1/1/1

A service provider experiences routing issues in a customer MPLS network. The customer has two sites that are connected over its core. Which feature can be used for troubleshooting?

• A.traceroute, to verify the label-switched path that is used for point-to-multipoint
• B.LSP Ping, to confirm that the label-switched path is used for transport
• C.disabling of Cisco Express Forwarding, to enable the use of LSP Ping and LSP Traceroute to verify the IP routing path
• D.redistribution between the BGP IPv4 and VPNv4 address families, to use labels to forward the customer packets
