In Cisco IOS, what must be configured to ensure that an MPLS TE tunnel becomes active?

• A.a path-option configuration, for either dynamic or explicit paths
• B.layer 3 addressing on the tunnel, to establish bidirectional communication over the tunnel
• C.the tunnel for autoroute, to ensure proper installation into the forwarding plane
• D.the tunnel with a minimum bandwidth value, to properly calculate CSPF

Refer to the exhibit.

Which two commands can be used to assign traffic onto MPLS TE Tunnel1001? (Choose two.)

• A.tunnel mpls traffic-eng bandwidth
• B.tunnel mpls traffic-eng autoroute announce
• C.ip route 0.0.0.0 0.0.0.0 Tunnel1001
• D.tunnel mpls traffic-eng priority 1 1
• E.ip route 0.0.0.0 0.0.0.0 10.0.0.1

Which option describes what happens when a labelled packet with a TTL of 1 is received by an LSR?

• A.The packet is dropped and an ICMP "time exceeded" message is label-switched from the expiring router on the same label switched path toward the destination and then back to the originating source.
• B.The packet is dropped and an ICMP "time exceeded" message is IP routed back to the sender.
• C.The packet is forwarded on to the next router where its TTL expires and from where an ICMP "time exceeded" message is generated and label switched back to the source.
• D.The packet is forwarded on to the next router where its TTL expires and from where an ICMP "time exceeded" message is generated and routed back to the source.
• E.The packet is dropped and an ICMP "time exceeded" message is label-switched from the expiring router back on a new path toward the source.

Which four pieces of information are stored for each prefix in the LFIB? (Choose four.)

• A.local label
