Huawei HCIE-Datacom V1.0 Sample Questions:

1. The following description of the LDPLSP establishment process is correct?

A) In the DoD mode of label publishing, for a specific FEC, the LSR does not need to obtain a label request message from upstream to distribute the label.
B) By default, LSRs are for the same FEC, and the received tag mappings can only come from the optimal next hop, not from the non-optimal next hop.
C) The process of establishing a LSP is actually to bind the FEC to the tag and advertise this binding to the LSP upstream LSR process.
