Actual exam question for Huawei's H31-161 exam

Question #: 61
Topic #: 1

Refer to the exhibit.

This figure shows the MPLS L3VPN networking. CE 1 and CE 3 belong to VPN

ACE 2 and CE 4 belong to VPN B. Two MPLS TE tunnels (5 Mbit/s and 10 Mbit/s) and an LSP tunnel are set up between PE 1 and PE 2.It is expected that a tunnel policy is configured on PE
1 to distribute traffic in the three tunnels and MPLS TE tunnels are preferred. Configurations on PE
1:
