Huawei HCIE-Datacom V1.0 Sample Questions (Q199-Q204):

NEW QUESTION # 199
In an MPLS domain, LSRs can be classified into ingress, transit, and egress LSRs based on how they process data. For the same FEC, an LSR can be both an ingress and a transit LSR of the FEC.

A. FALSE
B. TRUE

Answer: A

Explanation:
In MPLS (Multiprotocol Label Switching), Label Switching Routers (LSRs) handle packets based onFECs (Forwarding Equivalence Classes)and their positions in the label-switched path:
Ingress LSR:The entry point for labeled packets; it classifies packets into FECs and assigns the initial label.
Transit LSR:Intermediate routers that swap labels and forward packets along the LSP.
Egress LSR:The last router in the LSP that removes the label and forwards the packet normally.
An LSRcannotbeboth an ingress and a transit router for the same FEC, because an ingress LSR is defined as thestarting pointfor that specific FEC's LSP. If it's the ingress, it means the labeled pathstarts there, so it can't be in themiddle (transit)of that same path.
Therefore, the statement isFALSE.

NEW QUESTION # 200
During isis ' broadcast network database synchronization, is the following statement correct?

A. R2 As DIS, Hello time is 3 times that of a normal router.
B. RI and R3 maintain database consistency by periodically sending PSNP requests.
C. R2, as DIS, sends CSNP periodically.
D. R2 as DIS does not receive PSNP nouns for other routes.

Answer: C
